Maximum width on interstates, highways, roads. Commercial or private.

What are the maximum legal length, width, height, and weight limits allowed on roads, highways, or Interstates?

The legal maximum length, width, height, and weight permitted to travel, tow, or transport on local roads, highways, or Interstates in the United States and Canada are as follows.

Maximum legal limits Standard Metric
Length: 65 feet. 19.8 meters.
Width: 8 feet, 6 inches. 2.6 meters.
Height: 13 feet, 6 inches. 4.1 meters.
Weight: 80,000 pounds. 36,287 kilograms.
Notes: Always verify state/provincial legal limits prior to movement/transport.

These rules pertain to single personal vehicles (towed or otherwise), commercial motor vehicles including semi-tractors, trailers, and buses. Mirrors and certain safety devices (such as flags, etc.) may be permitted to protrude a “reasonable” distance further. Always obtain official consultation about any protrusion(s) you may have by contacting your state/provincial DOT office prior to any movement. Local city/county roads may vary from the maximum length/width/height/weight limits governed by federal guidelines.

Exceptions:

Within the state of Hawaii commercial motor vehicles are permitted the following maximum width on all highways (unless otherwise posted on the road by sign): Standard: 9 feet or 108 inches. Metric: 2.74 meters or 274 centimeters.

These roads usually have signs posted that display the maximum legal width permitted without obtaining a special travel permit. You should always inquire about the maximum widths permitted by the governing body of the particular road prior to traveling on it in order to prevent a fine or worse. In some situations depending on the width of the vehicle or shipment size, a route survey will be required prior to being granted permission to travel.

Maximum width allowed.

Maximum width laws are created to protect motorists and public assets. Know the maximums.

The importance of setting maximum widths for vehicles.

Safety and protection of motorists and public property are the primary reasons regulations have been set for maximum vehicle length/width/height/weight limitations.

A standard was required based on the dimensions of the existing roads that would protect any/all persons operating a motor vehicle on highways, roads, and Interstates. It should be noted public property is placed at risk for damage as well. Should motorists accidentally hit one of the many existing obstructions such as guard rails, signs, traffic signal poles, etc. liability while ultimately is the motorists, if it is not reported the state is required to repair damages which then is passed on to the taxpayers in both the USA and Canada. So maximum widths were created to protect both human lives but public property as well.

Noteworthy information:

“Federal width limits do not apply to special mobile equipment, which consists of self-propelled vehicles not designed or used primarily for the transportation of persons or property and only incidentally moved over the highways. Special mobile equipment includes the following, when moving under their own power: military or farm equipment; instruments of husbandry; road construction or maintenance machinery; and emergency apparatus, including police and fire emergency equipment. Federal rules do not require States to issue overwidth permits before allowing the operation of special mobile equipment. However, if States wish to allow other vehicles more than 102 inches wide (i.e. non-special mobile equipment) to operate on the NN, then States must issue special overwidth permits.” Reference Credit: FHWA website.

History:

“The Federal Government first enacted size regulations for CMVs with the passage of the Federal-Aid Highway Act of 1956. This Act provided a maximum vehicle width of 96 inches (2.44 meters) on the Interstate highway system. Subsequently, the Federal-Aid Highway Act of 1976 increased the allowable width for buses to 102 inches (2.6 meters). The Surface Transportation Assistance Act (STAA) of 1982 extended the same width requirement of 102 inches to commercial trucks. At the same time, the STAA expanded the highway network on which the Federal width provision applied from the Interstate to the National Network (NN) of highways.” Reference Credit: FHWA website.

Manitoba shipping regulations

2021 Manitoba DOT shipping laws, regulations, and limitations, for oversize and heavy-haul trucking over the roads and highways of Manitoba Canada.

Please share your expertise of knowledge with our other visitors below.

Legal 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: 3′ 3″ (1 meter) in front or rear.

Routine heavy-haul and oversize trucking permits.

Length: 30 meters in 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: Manitoba is overhang laws with permits.

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 Boxing day.

Superload information.

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 roadside 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.

Pilot car are escort vehicle information.

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 is 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 and escort vehicle requirements.

Pilot car/escort vehicle operators are required to take a Manitoba DOT certification course in order to operate in this province. The certification program is recognized by all US jurisdictions that require PEVO except for New York state. 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″), 2 – 175 mm (7″) diameter flashing lights mounted on the top of the sign-box on each side with 2 amber strobing or rotating lights a minimum of 203 mm (8″) mounted between the flashing lights on top of the box as well. The sign-box must light up and be visible from a minimum distance of 200 meters (656′). 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 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.

To operate in Manitoba you must obtain a light permit. More information is available by calling: 204-985-0920

Shipment, truck, and trailer markings.

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

All trucks that are hauling oversize or overweight loads must have a strobing, 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. A sign stating the nature of the load; “OVERSIZE LOAD”, “WIDE LOAD” or “LONG LOAD” must be mounted to the front and rear of the overall shipment. Signs must be a minimum of 12′ in height and 6′ in width with a yellow background and black letting with lettering thickness no less than 4 cm (1 5/8″) thick.

Idaho frost law restrictions 2021.



2021 Idaho winter frost/spring thaw laws and seasonal weight restrictions.

During the spring months when warmer temperatures cause the road surface to break up and generally deteriorate, the highways most affected are restricted to lower axle weights and speed restrictions.
The District will sign and mark affected state highways the day before the weight and/ or speed restrictions are in effect. The weight and/or
speed restrictions will be enforced the day after the Districts sign and mark the state highway.
On those sections of highways which are posted for legal weight, or to less than legal weight, trucks and buses weighing 10,000 pounds or
more will be restricted to 30 mph in critical areas. Speed zones will be marked with red and yellow markers. A red marker will mean speed
is restricted to 30 mph and a yellow marker will mean that legal speed can be resumed.
For information on operating restrictions for state highways posted for spring breakup limits or to check on a route of travel for construction
restrictions etc., go to 511.Idaho.gov and the trucking page.
It is important for the trucking industry to cooperate and comply with the load and speed limits. If compliance with the load and speed limits
are adhered to, the need for future, more restrictive, limits may be alleviated. Excessive violations may lead to the implementation of more
restrictive limits.

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. A sign stating the nature of the load; “OVERSIZE LOAD”, “WIDE LOAD” or “LONG LOAD” must be mounted to the front and rear of the overall shipment. Signs must be a minimum of 12″ in height and 6″ in width with a yellow background and black letting with lettering thickness no less than 4 cm (1 5/8″) thick.

Legal load limits.

Alberta DOT legal load limits:

Length: The overall maximum length allowed in Alberta without a permit is 23 meters (75′ 3″).
Width: The maximum width allowed is 2.6 meters (8′ 6″‘).
Height: The maximum height allowed in Alberta is 4.15 meters 13′ 7″.
Weight: 6,000 kg maximum on steer axle. Tandem axles: 17,000 kg. Tridum axels is 17,000 kilograms (37,478.6 lbs) as well. All axle weights are subject to the size of the tire.
Overhang: We have no information on allowable overhang in Alberta. Please share your knowledge with others below.
Notes:

* Super single tires require “New Generation, Wide Base” tires with a minimum tire width of 445 mm. Available by permit only. Super single tires do not apply to the steering axle.
** These weights for tridem axles apply to provincial highways only. The maximum weight for a tridem axle on a municipal road is 17,000 kg. Permits may be available to achieve heavier weights.
*** All axle weights are subject to minimum tire size. The maximum weight per tire shall not exceed the lesser of the tire manufacturer’s weight rating or the width of the tire stamped on the sidewall multiplied by 10 kg/mm.
Source: Alberta Transportation

Routine trucking permits.

Oversize and overweight trucking permits that are routinely issued by the Alberta DOT:

Length: 52 meters (170′ 8″) is about the maximum length you can get by with on a routine permit.
Width: 14′ 7″ wide depending on routing  for routine trucking permits.
Height: 5.3 meters (17′ 5″) in height is the cut off point for routine permits of course contingent on routing.
Weight: Weight is where you run into a problem. Alberta wants to know every single detail down to the size of tire you are running. Routing being a huge issue we can’t state a “routine” weight as it all depends on your axle spacings, combinations and tire sizes. Just for a safe number we’re going to say a routine permit caps out at 43,359.2 kilograms (100,000 lbs).
Overhang: 6.09 meters is about the most you can get on routine depending on routing.

Superload information.

Alberta superload information:

The maximum width normally allowed is 7.32 meters (24′) so anything over this width is a superload. We are researching information pertaining to shipping superloads in the province of Alberta Canada. If you happen to have expertise or knowledge of trucking superloads in this province please share your information for our other viewers below. Thank you.

Permitted travel times & restrictions.

Alberta DOT travel times and restrictions for oversize and overweight trucking:

The rule of 1/2 hour before sunrise until one full hour after sunset is observed in Alberta. Travel is allowed on Fridays until 3pm in the afternoon for loads that exceed 3.85 meters in width (12′ 7″) (WE WILL NEED TO DOUBLE CHECK THIS AS IT WAS LEFT AS A CORRECTION COMMENT BELOW). Travel is otherwise allowed and unrestricted on Saturdays unless stated on your permit.  Night travel is permitted for loads that are over length as long as you have 1 rear pilot car/escort vehicle and are on multiple lane roads. If your shipment is no longer than of 42 meters (137′ 10″) on a single lane road you will be required to have1 front pilot car/escort vehicle and 1 rear pilot car/escort vehicle. Weekend travel is permitted for loads that are over length only. If your shipment is in excess of 4.45 meters (14′ 7″) in width you will be permitted to travel only during daylight hours. If over 3.85 meters (12′ 7″) in width you may not travel on Sundays. There is not travel permitted on the following holidays: New Years day, Provincial day, Good Friday, Victoria day, Canada day, Family day, Labour day, Thanksgiving day, Remembrance day, Christmas day and on Boxing day.

Adverse weather conditions: If adverse weather conditions are reported you may not proceed with your shipment and are required to remain where ever you are. If adverse weather conditions interrupt your shipment you are required to pull over at the nearest suitable location even if it is on the side of the road unless you are over width. Over width loads must continue until they are able to completely turn off of the road and remain until adverse weather conditions stop. If your shipment is over 4.45 meters (14′ 7″) in width or 5.32 meters (17′ 5″) in height you are not permitted to travel with snow or fog visibility less than 150 meters (492′), if the road is covered with snow or ice or sleet or any other conditions that may effect the driver from proceeding with the absolute safety in mind first and foremost.

Frost laws: Alberta does have frost laws but when they are in effect changes every year based on testing with a heat flow model that measures to 30 cm below the surface. So, if you are shipping during the spring months you will need to call the number below for the exact frost law restriction dates. There are exemptions which include milk and bread trucks, farm machinery, water, fuel, fertilizer, mail and buses.

When pilot cars are required.

If your shipment is in excess of any of the following you will be required to have a pilot car escort you:

Length: If your shipment is in excess of 34 meters (111′) in overall length you are required to have 1 rear pilot car on single lane roads. For shipments in excess of 38 meters (124′ 8″) you are required to have 1 front pilot car/escort and 1 rear pilot car/escort.
Width: If your shipment is in excess of 3.85 meters (12′ 7″) wide you are required to have 1 front pilot car/escort on a single lane road or one rear pilot car/escort on multiple lane roads.

Maximum weight restrictions for trucking.

Learn more about oversize trucking and transport.

Each state or province has different regulations. The above is a North American average. Regulations for heavy haul and oversize trucking can be very complex once a shipment has been determined “heavy” or “oversize” and there is a classification system within each state that can even qualify a shipment as a “super load”. Once dimensions or weights exceed the legal maximums transport permits are required. Some shipments may require pilot cars or even pilot cars equipped with height poles or the trucking company may be required to have a route survey performed. It’s important to consult a professional before attempting to transport any objects, machinery or equipment that is oversize or over weight.

 

Know the legal limits anytime you transport a load.

Whether you are a professional truck driver or a novice with a pick up truck it’s always smart to know the laws. Public safety a big factor to consider when transporting large or heavy items. Public property should also be factored in as damages could crush you financially. Fines and possibly getting your vehicle towed and impounded are other factors to consider. Always consult a professional as well as local laws when considering transporting over dimensional or over weight shipments.
