Heavy haul trucking, pilot cars and permits.

Locate heavy haul, oversize equipment shipping companies, pilot cars and ordering trucking permits in Alaska:

Legal load limits.

Length:  53’ Trailer Length
Width:  8’6”
Height: 14’
Weight: Depending on route 80,000 lbs GVW.
Overhang: 3’ in the front, 4’ in the rear.

Kenworth double trailers in compliance with 80,000 pounds GVW laws.

Alaska requires any shipment over the weight of 80,000 pounds to have a special trip permit.

Routine trucking permits.

Trucking oversize and overweight permit limits:

Length: Shipping varies due to routing and season.
Width: Shipping rules vary depending on route and seaason.
Height: Over 14′ and once again everything varies depending on routing and season.
Weight: Single; 30,000 lbs, tandem; 56,000 lbs, tridem; 70,000 lbs, quadem 80,000 lbs, gross weight; 150,000 lbs. Depends on the route you wish to travel, distance and the bridges you intend on crossing.
Overhang:  20′ is a safe number but once again everything up here is seasonal as roads are closed or combined with weight frost laws may be in effect and limit you.  For the most part there is no such thing as a “routing” shipment in Alaska.

Notes:  When between the months of October 1 and March 31 for 1, 2 & 3 drive axle groups on truck tractors intending to travel the Dalton, Elliott or Steese highways between Fairbanks and Prudhoe Bay you can shift your legal axle weights to make them legal. The following weights on these routes apply: single; 22,000 lbs with 8′ 1″ minimum spacing between axles, tandem; 42,000 lbs, tridem; 48,000 lbs maximum.

When a pilot car is required.

Pilot car (escort vehicle) requirements:

Length: if overall length exceeds 85′ you are required to have 1 pilot car (escort). If overall length exceeds 100′ you are required to have 1 front and 1 read pilot car (escort).

Shipments over 14 feet wide or 150 feet long or 16’6″ in height must supply to the permitting department the exact route they wish to travel.

Heavy haul and oversize truck signs and flags.

A standard oversize load sign is required on the front of the tractor and the rear of the shipment if it exceeds 8’6″ and width. The sign must be yellow and have a minimum of 48 inches in width with black letters that are 10 inches tall and 2 inches wide. Acceptable signs when specified shall read “oversize”, “oversize load” or “wide load” for over width vehicles and/or shipments “oversize”, “oversize load” or “long load” for over length vehicles must be affixed to the rear of shipment when overall load exceeds 60 feet in length. Vehicles and loads with rear overhang exceeding 10 feet are subject to the following: must have “oversize” or “oversize load” signs and a amber high intensity rotating, flashing, oscillating or strobe type beacon which must be visible for a minimum of 500 feet from the end of the shipment. You must have either an extended light-bar or a rear pilot car or escort vehicle. All flags must be a minimum of 16” square and must be red. Flags are required to be on vehicles with loads wider than 10 feet and if overhang exceeds the legal limits in any direction.

Pilot car and escort vehicle requirements.

If the width of the shipment is over 10’6″ and up to 12 feet one pilot car or escort vehicle is required. For lengths over 85 feet and up to 100 feet one pilot car is required. If overhang is greater than 10 feet but less than 20 feet one pilot car or escort vehicle may be used. It is possible to use an extended lightbar and place of a rear pilot car. Heavy haul or overweight shipments with special bridge conditions are required to have two pilot cars if the width is 12 feet up to 14 feet to pilot cars or escort vehicles are required if the length is greater than 100 feet to escort vehicles or pilot cars are required. If the overhang exceeds 20 feet unless the rear is greater than 35 feet or the front greater than 60 feet one pilot car is required. For widths over 14 feet three pilot car vehicles or escort’s are required: two in the front and one in the rear. If you have overhang from the rear that is greater than 35 feet to pilot cars are required and for widths up to 18 feet but not more than 22 feet 4 pilot cars or escort vehicles are required. If road closures exist and you are an excess of 22 feet wide then you will be required to have 5 escorts or pilot cars. You may be permitted to use an extended light-bar when up to 20 feet of rear overhang and lieu of a rear pilot car.

Pilot car and escort vehicle requirements.

Pilot cars and escort vehicles may be passenger trucks and cars as long is they are under 10,000 pounds in total weight. Pilot cars and escort vehicles must carry commercial vehicle insurance. Pilot cars and escort vehicles will not carry any passengers. Pilot cars and escort vehicles will not act as a steer man or a tiller man for any load. Oversize load signs and beacons: all escort vehicles and pilot cars are required to be equipped with the appropriate signage. Depending upon the shipment you are working with this might be oversize, wide load or long load and the sign must be roof mounted with a high intensity rotating flashing oscillating or strobe type amber beacon light which must be visible from a minimum of 500 feet in any direction. When a pilot car or in escort vehicle is required to lead any oversize load the appropriate sign must be faced towards the front of the pilot car or escort vehicle when the pilot car or escort is chasing a load the appropriate sign must be faced towards the rear of the vehicle. Pilot car companies and escort vehicle drivers shall carry the following items and equipment at all times when escorting heavy haul and oversize loads: a 24 inch stop slow paddle sign, three bidirectional emergency reflective triangles, 15 pound rated B and C fire extinguisher, a reflector rise orange vest shirt or jacket, a first aid kit, a flashlight with extra batteries, a red cone and be equipped with a red hand flag.

Oversize vehicles are allowed to operate during hours of darkness under special lighting and taping requirements. Travel is permitted on the following holiday weekends memorial day for for July and Labor Day. Urban areas do restrict travel during peak hours be sure to refer to your permit for specific travel times especially in urban areas.

Spring weight and frost laws.

Weight restrictions and frost laws usually occur on all major routes in South, Central as well as interior Alaska. Typical months are from March 1st until the 1st July.

Learn the details of the winter frost laws, spring thaw laws and seasonal weight restrictions. Details for the USA and Canada by State/Province. Many areas incorporate temporary special weight limits and restrictions (frost or thaw laws) during the winter and spring months of the year. These temporary restrictions are usually referred to as “frost laws” or “thaw laws” and implemented typically during the month or March and April. In some Northern States and Provinces frost laws can still be in effect in July as it’s much colder in the North. Since these restrictions are implemented on a “as needed” basis it is possible many of the official government websites may not have published this temporary restriction in a convenient place as frost laws are also subject to change at any moment based on the temperature of the roads core. You want to be certain to check with the appropriate officials to verify the latest changes in the laws.

Why we have these laws and must protect our roads and highways.

In order to keep the trucking industry operating the Northern US states and Canadian provinces rely on engineers and scientific data to determine which dates frost laws will be in effect. With fairly recent advances in science and technology, data is much more reliable. This helps with the implementation of “Frost Laws” or “Seasonal Weight Restrictions” ensuring they are not implemented to early or late. While no State or Province desires to delay the transportation of goods through their territory it is imperative public assets are protected.

In areas that constantly get negative (ie: -10 below zero) temperatures the amount of damages has forced Northern US States as well as Canadian Provinces to create and enact laws that restrict vehicle weights during the spring and winter months (specifically trucking companies) when the roads and bridges are thawing out. There are all kinds of things that can go wrong with different types of roads and pavements. For example the State of Michigan has implemented permanent frost laws that go into effect during the months of March through May (and in some cases even June). Some routes require legal axle weight limits be decreased by as much as 35%. Some areas and local governments may also limit heavy-haul vehicle speeds to a maximum of 35 miles per hour during frost/thaw law months regardless of posted limits.

One of many examples is in Southern Oregon on old US Highway 1 (which follows the coast line from Mexico to Canada) the road is as much as 16 feet thick as years of pavement (even bricks) has been laid down year after year since the early 1900’s. It should be noted that today’s technology is able to provide us with roads that are flexible due to the engineering of the construction process and the materials used. Excessive weight exerted by overloaded axles (or a weakened supporting base) can cause the pavement to bend or deform. The strength of the road combined with its resistance to bending determines the amount of weight the roadway can handle.

Do I need a trucking permit? Legal load limits.

Nevada maximum load limits until a trucking permit is required:

Length: 75 feet maximum overall. Maximum trailer length is 53 feet.
Width: 8 feet 6 inches.
Height: 14 feet.
Weight: GVW 80,000 pounds. Single axle 20,000 pounds, tandem axles 34,000 pounds, tridem axles 42,000 pounds. Steer axle maximums require some math obviously. Here’s what the NVDOT says about it: “The maximum weight per tire, measured by pounds per inch of tire width, is 600 pounds per inch for the steering axle and 500 pounds per inch for all other axles, not to exceed the axle rating”. We say good luck with that, 12,400 pounds average???
Overhang: The maximum overhang allowed is 10 feet which overall must NOT exceed the maximum length of 75 feet.

Routine oversize and heavy-haul trucking permits.

These maximum dimensions/weights are considered routine oversize or heavy-haul trucking permits in NV:

Length: There really isn’t any routine maximum length. It all depends on proposed route and the state. After 105 feet in length it can get complicated.
Width: 17 feet. However some routes are restricted, see notes below;
Height: 16 feet.
Weight: Single axles 20,000 pounds, tandem axles 46,725 pounds, tridem axles 58,000 (to 59,000 see below) pounds. Determined by bridge formula, desired route, tire size and axle spacings especially for singles, tandems, tridums and quadem axles. Gross weights are: 5 axles 92,000 pounds with 70 feet minimum axle spacings, 6 axles 96,000 pounds with 70 feet minimum of axle spacings, 7 axles 101,000 pounds with 70 feet minimum of axles spacings, 8 axles 106,000 pounds with 70 feet minimum of axles spacings.
Overhang: No more than 15’ combined total but you want to check with them to make absolute sure as routing can effect this limit.
Notes: For weight restrictions Nevada has different routes marked. Choose the map you need for the entire state, western, eastern and southern restricted areas. You can also view a list. For purple, orange and green areas. Also, restrictions for width and weight are in effect on the following routes: route map, route list. Also note to get the extra 1,000 pounds as noted above (59,000 pounds on tridem configurations) you are allowed to use up to 2 tridem configurations only. Any additional tridem axle configurations will max out at 51,000 pounds. If you have tridem configurations on your tractor that will be counted as 1 of the 2. However, the distance between the steer axle and the center tridum axle must be a minimum of 18 feet. It is possible to to exceed this within reason but is reviewed case by case by the NVDOT permitting office.

Nevada superloads.

Requirements for extra-heavy or over-dimensional (superloads) in NV:

Nevada is picky about weights and heights. Rather than attempting to illustrate a list of items that may not apply we suggest if your shipment does not fall within the set maximums listed above it’s more than likely going to be considered a superload by NVDOT. The permitting process for superloads is different than the normal oversize or over-weight trucking permits in Nevada and must be fully drafted by the company or person requesting the permit. For instructions for the format your super-load application must be in see: Nevada-superloads.

NOTE: any special purpose or special needs loads that are outside of the normal permitting parameters will classify as a superload.

Legal travel times for oversize and heavy-haul loads.

Travel times and restrictions:

Remember to refer to your actual permit for travel times and restrictions. For Nevada daylight travel hours are defined as one half hour before sunrise to one half hour after sunset with some restrictions;  under 12 feet wide, 110 feet long or 15 feet tall may also travel during night hours and on weekends as long as you are not on I-80 between Sparks, NV and the CA state border or on I-15 between Las Vegas and the CA state border. There are no weekday curfews for any cities and if your load is under 12 feet wide, 100 feet long or 15 feet tall you may travel on holiday. However, if your load is in excess of these dimensions  holiday travel restrictions are on the following days: New Years day, Memorial day, Independence day, Labor day, Thanksgiving day and Christmas day. If a large event is predicted to create dense traffic they may restrict that date as well, ie: state fairs, etc.

When pilot cars or escort vehicles are required.

Heavy-haul or oversize loads may be required to be accompanied by a escort vehicle or pilot car if:

QUICK REFERENCE

Length:

  • over 105 feet in length requires on escort. This applies to both 2 lane and 4 lanes roads.

Width:

2 lane roads:

  • 12 feet requires 1 pilot car or escort.
  • 14 feet requires 1 pilot car and 1 escort.
  • 16 feet requires 3 total pilot cars and escort vehicles.
  • 17 feet will require a review which will probably require 1 pilot car and 1 escort and 1 police escort.

4 lane roads:

  • 14 feet requires 1 pilot car or escort.
  • 16 feet requires 1 pilot car and 1 escort.
  • 17 feet requires 1 pilot car and 1 escort and 1 police escort.

Height:

  • if over 16 feet and 6 inches in height you will be required to have 1 pilot car equipped with a height pole.

DETAILED REFERENCE

Length: If shipment is over 110 feet in length you are required to have 1 pilot car behind the shipment.
Width: If your shipment is over 12′ wide on up to a 3 lane road you are required to have 1 escort vehicle in the front of your shipment. If over 14′ wide on up to a 3 lane road you are required to have 1 escort in the front and 1 pilot car in the rear of the load.  If over 14′ wide on a 4 lane road you are required to have 1 rear escort. If over 16′ you are required to have 1 front pilot car and 1 rear escort on 4 lane and all other roads.
Height: Loads that are in excess of 15′ 6″ are required to have a front high pole pilot car at all times.
Weight: Pilot cars and escorts are usually not required on shipments over weight that are able to maintain the minimum posted speed requirements. If you are not able to maintain minimum speeds you will be required to have a minimum of a rear escort vehicle if travelling in urban and some rural areas.
Overhang: If in excess of 25 feet you will be required to have a minimum of 1 pilot car.
Notes: Some routes are completely restricot car.ted. If in the Hoover dam vicinity shipments are not permitted for anything over 10 feet in width but if 10 feet will require 1 pilot car and 1 escort.

Pilot car and escort vehicle requirements, certifications.

In order to operate a pilot car or escort vehicle in the state of Nevada you are required to have a minimum of the following:

First of all the state of Nevada requires that all pilot and escort vehicles be certified. If you are officially certified by another state then this is recognized by the state of Nevada as valid certification and you may operate within the state however, in order to have an amber light mounted to ANY vehicle you must first obtain a permit from the state which costs $2.00 per vehicle, per year. You can do that online by clicking here.
A pilot car or an escort vehicle is required to be equipped with a strobing or flashing amber light that is visible from a distance of no less than 500′ in daylight and from all 360 degree angles, mounted to the roof and above signs. The light must be a minimum of 50 candle power and if it is a rotating light must have a lens of no less than 5″ in diameter with a flash count or not less than 50 per minute. Any vehicle used for this purpose must be no less than 60″ in width, with a wheelbase of a minimum of 95″ with no more than 2 axles and a manufacturer’s gross weight of no more than 16,000 pounds.
Each vehicle must be equipped with a two way radio that is in constant contact with/to all parties involved in the shipment, 5 pound (minimum) fire extinguisher, 3 bi-directional 18″ road triangles, 1 stop/slow sign with 5′ pole handle, 1 hard hat, 1 reflective safety vest, a copy of the ANSI/ISEA manual which can be ordered online here for $30. Drivers must be a minimum of 18 years of age, have a valid drivers license, and must be flagger/flagman “capable or carrying out flagging responsibilities” (we strongly suggest a flagger safety class) of controlling traffic, wearing a approved safety yellow-green safety jacket or vest and equipped with a red flag and a stop/slow paddle of no less than 18″. Each vehicle should be equipped with proper signs that specify “oversize”,  “oversize load” or “wideload” as well as “long load” with black letters a minimum of 10″ in height with a letter thickness of no less than 1 5/8″ on a yellow background which are removed or covered while not in work transit mode. Pilot car and escort vehicles must have a placard on each side of the vehicle with the companies name and phone number clearly visible from a distance of no less than 50′.
Operators of pilot cars and escort vehicles will maintain a reasonable distance from the shipment which all depends on weather, traffic, road conditions and the speed you are travelling with reasonable distance defined by how much time it takes for the shipment driver to recognize your indications to stop, slow or pass as necessary.

Shipment, truck and trailer markings.

Truck, trailer and shipment required signs, banners and flags:

All trucking companies that are hauling oversize and overweight shipments must have a amber colored strobing or flashing light affixed to the top of the tractor trailer cab that is visible 360 degrees from a minimum distance of 500′. Signs that state the nature of the shipment; “oversize load” or “wideload” signs in the overall front and rear of the shipment. Signs will be no less than 7′ in width and 18″ in height with black lettering no less than 10″ in height with a lettering thickness of no less than 1 5/8″ thick on a yellow background. Signs must be mounted securely and free of any dirt or debris. Warning flags are to be used only in daylight hours and must be florescent orange in color with a minimum size distance of 18″ from one corner to the next corner and be placed at the outer most corners of the shipment as well as on any protrusions. IF the shipment is permitted to travel during night hours must have 2 constant display amber lights placed at the very most front extreme of the shipment,  two amber steady burning lights on the outer (side) center of the shipment and two red steady lit lights on the outer most rear of the shipment. THIS INCLUDES OVER-WEIGHT LOADS MOVING AT NIGHT.

Frost laws and restrictions for Nevada state.

Frost and thaw laws for Nevada:

Nevada is fairly elusive on frost and thaw law travel restrictions. They do provide a map but there is not much detail on it as far as the exact roads that must be travelled. You can view the frost law map or view this thaw law material published by the state DOT which does reference it as well. Then they also have some basic shipment route information that references it as well for the state of Nevada.

2020 – Federal Bridge Formula Weights Explanation.

2020 Easy – Federal Bridge Formula weights explanation.

The Federal Bridge Formula explanation.

Heavy-haul truck drivers should know exactly how to calculate the Federal Bridge Formula. Below is a very simple explanation to ensure compliance.

Explaining the maximum weight any combined set of axles on a truck and trailer can carry to cross a bridge on the Interstate highway system.  The following Federal bridge formula is used for calculating acceptable weights:

W=500 [ LN/N-1 + 12N + 36]

W= the overall gross weight on any group of two or more consecutive axles the the nearest 500 pounds.

L= the distance in feet between the outer axles of any group of two or more consecutive axles.

N= the number of axles in the group that are under consideration.

How do I determine Bridge Formula?

THIS IS A PERFECT EXAMPLE: Bridge formula is 30 times the wheelbase* in centimeters plus 18,000 kg.

*Wheelbase in the above Bridge Formula calculation refers to the maximum axles span (center of the first axle to the center of the last axle of any axle group) in a heavy commercial vehicle.

Axle spacing is another consideration that must be taken into account when looking at the Federal weight compliance laws.  In order to properly protect our bridges the number and the spacing of truck and trailer axles carrying the shipment must be calculated.  So a bridge weight formula applies when the gross weight on 2 or more consecutive axles exceeds the limitations on the formula, except that the 2 consecutive sets of tandem axles may carry a gross weight load of 34,000 pounds each if the overall distance between the 1st and last axle is  over a 36 feet minimum.

Exceptions to the Bridge Weight Formula:

There are exceptions.  Federal law does include an exception to the Federal Bridge Formula and the bridge table. 2 consecutive sets of tandem axles may carry 34,000 pounds each IF the overall distance between the first axle and last axles of these tandems is 36 feet or greater.  For example:  a 5 axle tractor semi trailer combination may carry 34,000 pounds of weight both on the tractor tandem (axles 2 and 3) and the trailer tandem (axles 4 and 5), provided the axles 2 and 5 are spaced at least 36 feet from each other.  Without this exception the bridge formula would allow for actual weight of only 66,000 pounds to 67,000 pounds on tandems spaced 36 feet to 38 feet apart. (References: U. S. Department of TransportationFederal Highway AdministrationFederal Bridge Formula Weights” – FWHA-FBFWHA-FBFF the .pdf)

Note:  In addition to the above formula weights Federal law says that a single axle is limited to a maximum of no greater than 20,000 pounds and that axles that are closer than 96 inches from each other are limited to a maximum weight of 34,000 pounds.  Also that gross vehicle weight be less than 80,000 pounds.

Federal law (23 U.S.C. 127) does include an exception to the Federal Bridge Formula and the Bridge Table—two consecutive sets of tandem axles may carry 34,000 lbs. pounds each if the overall distance between the first and last axles of the tandem axles is 36 feet or more. For example; a five-axle tractor and semitrailer combination may carry 34,000 lbs. pounds both on the tractor tandem (axles 2 and 3) and the trailer tandem (axles 4 and 5), if axles number 2 and 5 are spaced at least 36 feet apart. Without this exception the Federal Bridge Formula would allow an actual weight of only 66,000 pounds up to 67,500 pounds on tandems spaced 36 to 38 feet apart.

Legal load limits.
British Columbia legal load limits:

Length: 14.65 meters (48.06′) from the kingpin to the rear most portion of the trailer. No combinations in length over 23 meters (75.45′) overall without a permit. A 53 foot semi-trailer is allowed provided the lift axle is raised.
Width: No shipment may travel if in excess of 2.6 meters in width (without a permit) unless it is a shipment of hay which is limited to 3.1 meters (122″) or rear view mirrors which are limited to 30 cm (11.81 inches)on each side, additional auxiliary devices are allowed 30 cm (11.81 inches) and tires are allowed an additional 10 cm.
Height: No shipment may travel if larger than 4.15 meters (163″) in height without a permit.
Weight: Single axle: 9,100 kg (20,062 lbs) and the same for tandem and tridum axles. A tridem pole trailer: gross weight on any two adjacent axles in a tridum axle group must not exceed 17,000 kg (37,478 lbs). The maximum licensed gross vehicle weight of a vehicle or combination of vehicles must not exceed 63,500 kg* (139,994 lbs) without a permit (see; en B.C Regulation 95/2006, s. 3.)* THIS AMOUNT SEEMS EXCESSIVE. THIS IS THE NUMBER OUR RESEARCH PRODUCED. See; reference link below in “notes” under “maximum gross weight”. See also “comments” at bottom.
Notes: Not matter what a permit states if there is a sign posted on a highway or road that contradicts your permit the sign will take precedence over the permit so you must immediately stop traveling and get clarification. Section reference: Copyright Queens Printer Victoria, British Columbia, Canada.
Overhang: 1m in front and .061 – which seems a little odd to us as the rear maximum seems short. Please contact the BC DOT to verify.

Routine trucking permits.
Oversize and overweight trucking permits that are routinely issued by the British Columbia DOT routinely:

Length: 27.5 meters (90 feet, 2 and 43/64 fourths on an inch) in the maximum length for a routine permit in B. C.
Width: 4.4 meters (14 feet, 5 and 15/64 fourths of an inch) is the maximum with you will get from BC DOT on a routine permit.
Height: There is no number provided. The British Columbia DOT permit office wants to assess every load that is over height based on intended routing.
Weight: This is the same as height. They will not give you a solid number for routine. We are going to suggest 63,500 kg (134,994 lbs) since we had trouble locating what we feel was a reasonable maximum limit above for “legal loads limits”. we sure welcome your comments below.
Overhang: 6.5 meters (21 feet, 3 and 29/32 seconds of an inch) for routine permits for overhang.

NOTES: If your shipment is oversize AND overweight you will be required to have two separate permits. Oversize loads are required to have safety flags no less than 16″ x 16″ (46.64 cm) square and be red in color.

Superload information- extraordinary loads.
British Columbia superload information:

Superloads in British Columbia or “extraordinary loads” are defined by the DOT any shipment that is in excess of 85,000 kilograms GVW in weight, 4.4 meters (14 feet, 5 and 15/64ths of an inch) in width, 4.88 meters (16 feet and 1/8th inches) in overall height. Depending on your route you may not be classified as a “Superload” as the British Columbia DOT has  pre-approved designated routes. You can find more (limited) information on super or extraordinary loads here.

Permitted travel times & restrictions.
British Columbia DOT travel times and restrictions for oversize and overweight trucking:

The rule of daylight is defined as 1/2 hour before sunrise to 1/2 hour after sunset in B. C. No travel is allowed after 2 PM on Friday until 12:01 AM on Monday for any load in excess of 3.8 meters (12′ 6″) in width. If your shipment is over 3.5 meters (11′ 6″) in width you are only allowed to travel during daylight hours only with the exception of the Peace River region. For holiday travel restrictions you may not travel after 2 PM on the day before the holiday and after 12:01 on the day after the holiday. Holidays are New Years day, Provincial day, Good Friday, Victoria day, Canada day, Family day, Labour day, Thanksgiving day, Remembrance day, Christmas day and Boxing day.

When pilot cars are required.
British Columbia DOT requires a pilot car (escort vehicle) to accompany your shipment if you are in excess of any of the following dimensions or weights:

Length: For shipments in excess of 27.5 meters (90′) in length you will be required to have 1 rear pilot car (escort vehicle) on all roads. For shipments over 27.5 meters (90′) in length 1 front pilot car/escort and 1 rear pilot car/escort is required.
Width: Shipments in excess of 3.5 meters (11′ 6″) wide you will be required to have 1 front pilot car on two lane roads or 1 rear pilot car/escort on multiple lane roads. In some cases a beacon light may be substituted. In many cases night travel is granted at 304.8 cm (10′ wide). If granted night travel you may be required to have 1 pilot car/escort in the front if your shipment is over 3.2 meters (10′ 5 and 63/64 fourths of an inch”) in width. Shipments that are over 3.5 meters (11′ 5 and 51/64 fourths of an inch”) wide up to 4.4 meters (14′ 5 and 15/64 fourths of an inch) require 1 front pilot car/escort vehicle. Shipments that are over 3.5 meters (11′ 5 and 51/64 fourths of an inch”) wide are permitted to travel at night only.
Height: Depending on your route the BC DOT permit office will determine if you are required to have a pilot car/escort vehicle.
Weight: Weight is on a case by case basis. As long as your shipment can maintain the minimum required speed limit you will probably not be required to have a pilot car/escort by the British Columbia DOT permits office.
Overhang: If you are have more than 6.5 meters (21′ 3 and 29/32 seconds of an inch) of overhang you will be required to have 1 rear pilot car/escort.

Pilot car certifications.
Pilot car (escort vehicle) certifications and requirements for operating in British Columbia:

Pilot car/escort vehicle operators at this time are only required to: 1.) have a valid drivers license and 2.) be over 18 years of age.  We are getting reports that a certification program is in the works but at the time of this update (March 2, 2014) these above 3 requirements are all that is needed to operate a “pilot car” or “escort vehicle” within the Province of British Columbia (see comments below for more information). Also see; British Columbia Pilot Cars laws. Your vehicle is required to have a lighted sign box that is a minimum of 180 cm x 35 cm x 10 cm (72″ x 14″ x 4″),  have 2 – flashing lights mounted on the top of the sign box on each side with 2 amber strobe or rotating lights a minimum of 203 mm (8″) mounted between the flashing lights on top of the box as well.

The minimum acceptable size for a rotating amber light is 15 cm in diameter and for strobe lights 11 cm in diameter. Either type of lamp must emit light flashes in 360 degrees.

The sign box must light up and be visible from a minimum distance of 200 meters. The sign box must have either a red and white D sign or a yellow with black lettering stating “OVERSIZE LOAD”, “WIDE LOAD”,  OR “LONG LOAD”. If you have the “D” sign your letter must be no less than 20 cm (8″) in height with a 4 cm (1 5/8″) line thickness. If you have the yellow sign your lettering must be no less than 20 cm (8″) with a 4 cm (1 5/8″) line thickness. The sign box must be mounted on the top of the vehicle and covered when not in operation. You are also expected to have the following items inside of the vehicle: CB radio or high powered 2-way radio, first aid kit, fire extinguisher type A, B & C of at least a 2 liters, 3 reflective road triangles, 3 traffic cones, reflective vest (worn while working), slow/stop sign, 3 red or orange safety colored flags no less than 40 x 40 cm (16″ x 16″), nose cone flashlight and a hard hat.

Shipment, truck & trailer markings.
Truck, trailer and shipment required signs, banners and flags:

All trucks that are hauling oversize or overweight loads must have a strobe, flashing or rotating amber light mounted to the roof that is visible from 360 degrees at a minimum distance of 200 meters (656′). All 4 outermost corners of the overall shipment and any obtrusive points must have flags mounted to them that are safety red or orange in color no less than 40 cm x 40 cm (16″ x 16″) and have the flags exchanged for lighting if moving during the night.

You will need to document why it is in the best interest of the people of Washington state to grant you permission to perform the move, show that it can not be reduced in any way reasonable, have a mechanical drawing of the truck, trailer and shipment showing all of the axle positions, why you can’t perform the shipment via water, have an iron clad route in mind, a detailed plan for controlling traffic, how you plan to use your pilot cars, show that you are aware of all railroad route time tables if performing any crossings, and have a way to prove that any kind of emergency vehicle at any time can easily get past you. If you have all of this together then the Washington DOT will take a look at it and may even charge you for their time. Superloads in Washington should be completely handled by a professional or you may loose time and money.

Legal limits.

Legal load limits:

Length: The overall maximum length without a permit is 23 meters.
Width: The maximum width allowed without a permit is 2.6 meters.
Height: 4.15 meters is the maximum height allowed by Manitoba DOT without a permit.
Weight: 9,100 kg on steer (seems high to us so NOT a confirmed number –  use reference link below), tandem axles: 17,000 kgs, tridem: 17,000 kgs,  or 3 axle combination with proper spacing of a 23,700, quadem: 31,600 kgs, 5 axle: 39,500 kgs and 6 axles: 46,500 kgs. Let me refer you to our reference on this for clarification from Manitoba DOT as there are different weight classes.
Overhang: Our researchers are unable to find any information on maximum allowed legal overhang. We did find the pilot car requirements of 25 meters. We will call and update at a later time or you can call Debra Martin at: 204-326-8292 M-F 8-4 – if you do please comment below as this author is writing on a Sat. and they are closed. Thank you!

Routine oversize and heavy haul trucking permits.

Oversize and overweight trucking permits that are issued routinely by Manitoba province:

Length: 30 meters on length is about all you are going to get.
Width: 5 meters wide for routine permits depending on routing.
Height: Depending on routing as Manitoba DOT has designated routes the maximum height is 4.8 meters.
Weight: We were unable to get a solid figure. Manitoba DOT has different zones for weight restrictions so it all depends on which zone you need to travel in. See Manitoba DOT zone map.
Overhang: Based on the comment they made on 25 meters of rear overhang we are going to say that up to this amount is routine. If you need to speak to them call the number located above in “legal load limits” in the “overhang” section.

Superload information.

Manitoba DOT information on suplerloads or extra ordinary loads:

We will do more research on superloads in Manitoba in the future. The Manitoba DOT documentation does not cover or mention much about them so we will need to speak with someone on the phone. We are able to  see that they are well versed in shipping superloads as they mention in their online documentation that there will make arrangements to remove road side signs and replace them for shipments that are in excess of the road width. We will get back to this section soon but in the meantime appreciate any comments you may be able to leave for other visitors below.

Permitted travel times for oversize and heavy-haul loads – restrictions.

Manitoba DOT permitted travel times and restrictions:

Daylight travel times are defined as from sunrise to sunset in Manitoba. No travel is permitted after 3 PM on Fridays during the summer months for shipments in excess of 3.4 meters (11′ 2″) wide on seasonal restricted roads. In the spring shipments in excess of 4.6 meters (15′) in width are not allowed to travel on roads during the spring restriction times. On routes that are not seasonally restricted you may proceed (multiple lane roads) until 3 PM as long as you are no wider than 3.7 meters in width (12′ 2″) on Friday and resume travel on Saturday at sunrise however if you are in excess of 25 meters in length (82′) you are not permitted to travel after 3 PM on Fridays during the summer months if you are on a seasonally restricted highway and resume on Saturday at sunrise – you are allowed however to travel on holidays. Sunday travel is permitted for loads up to 3.85 meters (12′ 7″) in width on all roads that have no seasonal restrictions. On a single lane highway on holidays you can not exceed 3.4 meters (11′ 2″) in order to travel. On multiple lane roads you can travel only if you are less than 3.7 meters (12′ 2″). This is very confusing so always refer to your permit for final verification but to help the matter lets go over the restricted routes:

  • Highway 1 from Falcon lake to the Manitoba/Ontario border.
  • Highway 6, 8, 9, 15, 16, 44, 307, 313, 317.
  • Highway 10 from the US border to Riding Mountain National Park.
  • Highway 11 but only north of highway 44.
  • Highway 12 but only north of highway 15.
  • Highway 59 from the west boundary line of Brokenhead to Grand Beach and the South perimeter of St. Malo

Here is the Manitoba link for spring road restrictions with zones to help you with interpretation. Holidays observed are: New years day, Provincial day, Good Friday, Victoria day, Canada day, Family day, Labor day, Thanksgiving day, Remembrance day, Christmas day and on Boxing day.

When pilot cars are required.

Manitoba DOT requires you to have a pilot car if your shipment is in excess of any of the following regulated limits:

Length: Shipments that are in excess of 30 meters (98′ 5″) long require 1 pilot car/escort vehicle on the rear of the shipment on all roads. For shipments that include a booster of a jeep that are over 31 meters (101′ 9″) you are required to have 1 rear pilot car vehicle on all roads.
Width: If your shipment is in excess of 4.6 meters (15′) wide then you are required to have 1 front pilot car on single lane roads and 1 rear pilot car/escort on multiple lane roads. If your load is in excess of 3.66 meters (12′) but less than 4.55 meters ( 14′ 7″) then you are permitted to travel at night as long as you have 1 front and 1 read pilot car/escort vehicle on all roads and highways. Mobile homes can travel at night on multiple lane roads as long as it does not exceed 5 meters wide (16′ 4″) but are required to have 1 pilot car on the rear.
Height: If you are approved for a shipment that is over the legal limits Manitoba DOT has designated routes and you are not required to have a pilot car.
Weight: As long as your shipment is able to maintain the minimum speed requirements you will more than likely not be required to have a pilot car as long as your shipment is overweight only.
Overhang: Overhang is approved on a case by case basis. Check with the Manitoba DOT for further information to see if your shipment will require a pilot car due to excessive overhang.

Pilot car certifications.

Do I need a trucking permit? Legal load limits.

Texas maximum load limits until a trucking permit is required:

Legal Loads:
Length: Trailer length maximum is 59 feet. Overall length is 65 feet.
Width: 8 feet and 6 inches wide max.
Height: 14 feet tall max.
Weight: 80,000 pounds overall GVW, 20,000 pounds on single axles, 34,000 pounds on tandem axles and 42,000 pounds on tridem axles.
Overhang: 4 feet in the rear and 2 feet in the front maximum.

Routine oversize and heavy-haul trucking permits.

These maximum dimensions/weights are considered routine oversize or heavy-haul trucking permits in Texas:

Length: up to 180 feet long or see superload section.
Width:  20 feet wide on “routine” permits (Go Texas!) however only 16 feet wide on the interstates.
Height: again Texas has it all together with the height set at 18 feet and 11 inches maximum for routine oversize trucking permits. Anything over this height is going to require a route survey.
Weight: up to 240,000 pounds for routine heavy haul trucking permits however if the shipment is in excess of 200,000 pounds with less that 95 feet of axle spacings you will have to apply for a heavy haul superload trucking permit. On single axles: 25,000 pounds. Tandem axles: 46,000 pounds. Tridum axles: 60,000 pounds and quadem axles: 63,000 pounds (confirmed May 31, 2018). 5 axles 73,260 pounds. Trunnion axles 54,000 pounds. On restricted routes: Single: 22,500 pounds, tandem: 41,400 pounds, tridum: 54,000 pounds, quad: 63,000 pounds, 5 axles 73,260 pounds, trunnion: 54,000 pounds. 5 axels gross weight 105,000, 6 axels: 119,000, 7 axles: 129,000 lbs, 8 axles depends on your axle configurations.
Overhang: Go again Texas DOT!  Front overhang is 25′ and rear overhang is 30′ in length for routine Texas oversize trucking permits.  Nice job folks!
Notes: If over 125 feet in length, 20 feet wide or 18 feet and 11 inches tall you will be required to have a route inspection. A flatbed trailer can not be used for a shipment that is considered a “wideload” and a “over-height” load. Your permit will be rejected and you will loose your payment. If a shipment has 2 different oversize dimensions (ie; long and wide or wide and tall), then it automatically will be required to have 2 pilot cars or escort vehicles.

Texas superloads.

To keep this simple any shipment that exceeds the above dimensions/weights in the “Routine” section above will more thank likely be classified as a superload shipment in the state of Texas. Superload permits issued in the state of Texas usually take at minimum 2 weeks time to be approved.

Legal travel times for oversize and heavy-haul loads.

Travel times and restrictions for heavy-haul and oversize loads:

One half hour before sunrise and one half hour after sunset is considered daylight time. Night time travel is permitted in the state of Texas if the shipment is less than 100 feet long or 10 wide on the Interstate highways only. If the shipment is ONLY overweight it may travel at night on any roads.  Weekend travel is permitted.  You can travel on some holidays but there are some limits;  if the length is in excess of 110′ long, height is in excess of 16′ or width is excess of 14′ you may NOT travel on the following holidays: New Years day, Memorial day, Independence day, Labor day, Thanksgiving day and Christmas day.  The Texas state DOT permit office is closed on these days as well.  Texas does have quite a few travel time curfews in high density traffic areas so be sure to refer to your permit. These typically range from 6-9 am and 3-6 pm (example only).  Each permit issued by the Texas DOT will specifically state exactly what the curfew law is. No Texas state heavy haul or oversize trucking permit is valid without the specific curfew restrictions attached to it.

Lights, safety flags and warning signs for heavy haul and oversize loads.

Required marking, safety flags, warning signs for heavy haul and oversize loads:

When transporting heavy haul and oversize loads the tractor trailer unit must have their low beam headlights turned on at all times. Any shipment that extends from either side of the actual trailer width requires red or orange florescent warning flags that are no less than 16 inches square as well as red lights/lamps. If you are transporting anything that has rear overhang in excess of 4 feet from the rear of the trailer you will be required to place two red lamps at each rear extreme corner. Red lights must be visible from a minimum distance of 500 feet. Any shipment over 8 feet and 6 inches wide will require a strobe and red lighting is addition or warning flags. Trucks must have either 1 strobing amber light with a minimum base size of 8 inches or 2 simultaneous flashing amber lights mounted on the roof of power unit. Signs must be applicable to the shipment being moved such as “oversize load”, “long load”, etc. Signs must be a minimum of 5 feet in width but no wider than 7 feet with a yellow background and black letters a minimum of 8 inches tall.

When pilot cars or escort vehciles are required.

Heavy-haul or oversize loads may be required to be accompanies by a escort vehicle or pilot car if:

Length: If shipment is over 110′ in length and up to 125′ you will need 1 pilot car in the rear.  Over 125′ in length requires 1 pilot car or escort vehicle in the front and 1 on the rear.
Width: Shipments 14 feet to 16 feet wide will require 1 pilot car vehicle in front on a 2 lane road and 1 on the rear on a 4 lane road.  If shipment is in excess of 16 feet, 1 front and 1 rear pilot car or escort vehicle will be required on all shipments on all roads and highways.
Height: If height of load exceeds 17′ a front high pole car is required. If the shipment is over 18′ in height you will be required to have 1 high pole and 1 rear escort.
Weight: If the shipment is able to maintain minimum speeds no escort vehicle is required.
Overhang: Front overhang up to 20 feet on some 2 land roads will require 1 pilot car or escort vehicle in the front.  On a 4 lane front overhang up to 25 feet requires 1 pilot car (escort) on the rear.  Rear overhang; over 20 feet but not more than 30 feet requires one pilot car (escort) on the rear of shipment. If over 30 feet of overhang 2 pilot cars or escort vehicles will be required and you will need to get special approval for the permit to be issued.

Pilot cars/escort vehicle certifications and requirements.

Pilot car or escort vehicle mandatory operator certifications and vehicle requirements:

At the date of this publish (06/20/18) there are no certifications required by the state of Texas for pilot car or escort vehicle operators. Vehicle requirements: All pilot cars/escort vehicles must display either both bumpers or 1 roof mounted “OVERSIZE LOAD” or “WIDELOAD” sign (which ever is applicable) visible from both the front and rear of the vehicle and only displayed while working.

Vehicles must be equipped with a CB radio or 2-way communication device and be in constant communication with all parties assigned to the movement.

It is only our express opinion that pilot cars also have a minimum of the additional items but not required:  2 – 5 pound fire extinguishers type A, B and C, a paddle sign with the word “STOP” on one side and “SLOW” on the other with dimensions of no less than 18″ in diameter with a minimum of 6″ letters.

Length: 120 feet long overall.
Width: 16 feet wide. Anything that is in excess of 4 inches from either/both sides of the trailer is required to be flagged in front and rear. Flags must be 12 inches square minimum and safety colored orange or red.
Height: 15 feet about does it for max height in TN on most routes. At 15 feet in height you can count on being required to have a high pole (hi pole) escort.
Weight: Single axle 20,000 lbs, tandem axles 40,000 lbs, tridum axles 60,000 lbs, quadem axles, 80,000 lbs. Gross weight on 5 axles is 100,000 pounds, 6 axles 120,000 pounds, 7 axles 140,000 pounds, 8 axles 160,000 pounds.  Once you hit 150,000 pounds that’s in in TN.  You’re going to have to be granted special permission for your shipment to move.
Overhang: Depends on routing.  10 feet is probably not going to be a problem but much more than that is going to create delays.  Over 1/3 of actual item being shipped length is not going to go over real well.  Consider a different trailer is you are time sensitive. If shipment is extended beyond 4 feet from the rear of trailer red safety flags a minimum of 12 inches square are required on both sides.

Tennessee super-loads.

Requirements for extra heavy or extra dimensional (superloads) in TN:

Shipments that are defined as super-loads are typically any that exceed any of the weights or dimensions described above in routine oversize and heavy-haul trucking permits. Shipments that are in excess of  15 feet in height or 16 feet in width will not be allowed to travel via conventional permits if they is a public safety factor including potential property damages. Shipments that exceed 16 feet in height are seriously frowned on in the state of TN and will require additional approval to be considered for permitting.

Legal travel times for oversize and heavy haul loads.

Travel times and restrictions:

The one half hour before sunrise and one half hour after sunset basic rule applies. No travel on Sunday. If over-weight only continuous travel is permitted. Night time travel for overweight is not a problem as long as minimum speed limit can be maintained by carrier.  Anything other than over-weight is daylight travel only for the most part unless otherwise specified on your permit.  In cities and high density traffic areas travel may be restricted between 7 and 9 AM and 4 and 6 PM on weekdays – be sure to refer to your permit. On the following holidays no travel is permitted: New Years day, Good Friday, Memorial day, Independence day, Labor day, Thanksgiving day and Christmas day.  The Tennessee state DOT permit office is closed on these days as well and additionally on:  Martin Luther King day, Presidents day, Columbus day, Veterans day and the day after Thanksgiving. However, travel is not restricted on any of these days if it is not on a Sunday unless otherwise specified on your permit. Note that failure to comply with designated travel time restrictions can result in the carrier/shipment being placed on permit issue restriction for 365 days. Inclement weather such as ice, snow, rain, wind and anything that restricts reasonable visibility is observed. For more information on TN road conditions.

Pilot car and escort vehicle requirements, certifications.

Pilot car or escort vehicle mandatory operator certifications and vehicle requirements:

NOTE BE ADVISED NEW LAWS FOR 2018 WILL BE RELEASED VERY SOON. Tennessee state shipping regulations state that all pilot cars/escort vehicles must display either both bumpers or 1 roof mounted “OVERSIZE LOAD” or “WIDELOAD” sign (which ever is applicable) visible from both the front and rear of the vehicle and only displayed while working. Sign must be at least 5′ long but no greater than 7′ and 12″ in height but no greater than 18″ in height, yellow in color with black letters no less than 8″ in height but no more than 10″ in height and lettering must be a minimum of 1.4″ in width.  Vehicle must be equipped with 2 horizontally mounted rotating (if rotating 8″ base is required) (or strobe) amber colored flashing or strobe light which must be visible from a 360 degree angle from a minimum of 500 feet. Vehicles must be equipped with a CB radio or 2-way communication device and be in constant communication with all parties assigned to the movement.

It is our opinion that pilot cars also have a minimum of the additional items but not required:  2 – 5 pound fire extinguishers type A, B and C, a paddle sign with the word “STOP” on one side and “SLOW” on the other with dimensions of no less than 18″ in diameter with a minimum of 6″ letters.
