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.

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.

Legal load limits.

Length: 65’on non-designated highways and 57′ 6″ max trailer length for all other areas.
Height: 14′
Width: 8′ 6″ or 102″ depending on route.
Weight: 80,000 lbs. on interstate roads and 80,640 lbs. on all others.
Overhang: We do not have any information on the legal overhang limits. If you have information please share it with others below.

Routine trucking permits.

Length:  There is no clarification on length. We do know that over 190′ is classified as a superload. Routing would be the issue. Please share your expertise below.
Height: 14′
Width: Routine limits on width is another bloodstone.  Routing (mainly sub-routing) is complicated in this state.
Weight: These are the routine weights that are allowed on the Interstates in New Mexico. Still routing is the determining factor. Single axle; 23,000 lbs, tandem axles; 46,000 lbs, tridum axles; 60,000 lbs, quadem axles; 68,000 lbs. Roads other than the Interstate all depend on your axle spacings. Gross weights are: 5 axles; 105,000 lbs, 6 axles; 119,000 lbs, 7 axles; 127,000 lbs, 8 axles; 150,000 lbs. Of course, all of this is totally dependent on the New Mexico DOT so do not assume anything as it seems they want to review any shipments that are pushing the upper limits as they hold back information so it’s “pending approval”.
Overhang: We do not have any information on the legal overhang. If you can help please comment below.

Superload information.

Length: anything over 190′ long.
Width: 20′ wide for sure. Possibly less on sub-routes.
Height: We have no number yet.  The maximum routine is 14′ but that is pretty low. We would think that 17′ would be superload height based on the information we have on this state but routing is everything when it comes to height.
Weight: 200,000 pounds and you are a superload.

Travel times & restrictions.

The sunrise to sunset rule applies in the state of New Mexico. Sunday travel is not allowed and holiday restrictions apply (if overweight interstate travels only with a pilot car). If the holiday is on a Friday then you can only travel until sunset on Thursday. If the holiday is on a Saturday you can not travel past Friday at sunset.  Resuming travel. If the holiday falls on a Saturday you can’t resume travel until Tuesday. Travel is not permitted on the following holidays: New Year’s Day, Memorial Day, Independence Day, Labor Day, Christmas Day, and Thanksgiving day.

Note: In the cities of Albuquerque, Espanola and Santa Fe you can not travel from the hours of 7 – 9 AM and 4 – 6 PM as high traffic density is the worst during this time.

When pilot cars are required in New Mexico.

Pilot cars (escort vehicles) are required for and shipments that exceed 14′ in width and can be even lower depending on the route you wish to travel.  Pilot cars (escorts) are required for loads exceeding 14′ 6″ on any of the restricted highways, see the pilot car (escort vehicle) map developed by the New Mexico DOT which will furnish all pilot cars (escort vehicles) a complimentary map if you ask. Over-length shipments may require a pilot car (escort) for shipments in excess of  90′ in length overall. If you are over 110′ overall you will be required to have 2 pilot cars (1 front & 1 rear). If the width of the load exceeds 20′ wide you will be required to have a police escort and flag person that is certified to control traffic. The maximum height is 16′. If you are over this height you will be required to have a high pole pilot car (escort vehicle).

Pilot car certifications required.

At the New Mexico DOT port of entry, your pilot car (escort vehicle) will be required to undergo an inspection for certification by the New Mexico DOT while operating in their state. The driver will be required to show all of the following equipment and documentation in/on the vehicle for inspection purposes:

  • Condition of vehicle tires must be excellent and a wheelbase of the vehicle must be a minimum of 100″ and have a rated capacity of no more than 1 and 1/2 ton vehicle.
  • Two-way radio or CB radio units that are capable of transporting well over 10 miles minimum.
  • 2 amber flashing or strobing lights on the two most outer edges of the vehicle that are visible 360 degrees from a distance of no less than 500′. Headlamps are required to be turned on as well when working.
  • At least 1 “OVERSIZE LOAD” sign must be displayed on the vehicle. This sign must have a yellow background with minimum dimensions of 5′ in width and 12″ in height with black letter thickness no less than 1″ thick. Best if mounted on top but can be mounted to the rear if chasing or front if leading.

  • Certificate of insurance meeting the minimum requirements for New Mexico DOT which is $50,000, $100,000, and $25,000.

The New Mexico DOT inspections are annual inspections and the duration of validity is determined by the expiration date on the insurance certificate or 1 year, whichever is first.

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).

Width: If 10′ to 12′ wide you will be required to have 1 pilot car (escort vehicle). If width exceeds 12′ and up to 14′ you are required to have 1 front and 1 rear pilot car (escort vehicle). From 14′ to 18′ in width you will be required to have 3 pilot cars. 2 front on 4 lane and 2 rear on 2 lane roads with the additional at either end. 18′ up to 22′ in width will require 4 pilot cars (escorts); 2 in front and 2 on the rear. If over 22′ in width you will be required to “close and roll” (closing the road as you move) requiring you to have 5 pilot cars as well as a minimum of 1 police escort.

Weight: You may be required to have a pilot car/cars if you are not able to maintain the minimum speed limit and on some designated bridge crossings depending on your weight class.

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.

The great state of Arizona official seal.

Please share your expertise of Arizona state DOT trucking regulations with other visitors below.

As per the state of Arizona please read the following:

“The Arizona Department of Transportation in cooperation with state representatives, industry, the Department of Public Safety  and local law enforcement personnel work in collaboration to update and amend oversize and overweight special permit rules containing special permit requirements, restrictions and allowances for transporting oversize and overweight vehicles and loads on highways under the jurisdiction of the Department. This is a council established in statute and makes up the Over-dimensional Permit Council.

These rules detail the eligibility, application and use requirements for a variety of permits the Department currently issues to commercial motor carriers for transporting vehicles or vehicle and load combinations exceeding the maximum size or weight limitations provided by statute.

Each special permit provided by the Department under these rules is specifically authorized by statute.  The oversize and overweight special permits issued under these rules are that each permittee issued a particular class of permit is subject to the same activities, practices, requirements and restrictions applicable to that permit type. The statutes additionally provide authority for issuance, conditions, restrictions, approvals and fees.”

Do I need a trucking permit? Legal load limits.

Arizona maximum load limits until a trucking permit is required:

Length: Anything over 65 feet in length overall requires a permit on non-designated highways.
Overhang: 3 feet in the front and 6 feet off of the rear of trailer maximum (make sure your route is approved for overhang as there are location variations).
Weight: 80,000 pounds overall (GVW), 12,000 pounds on steer axle.
Width: 8 feet and 6 inches wide maximum.
Height: 14 feet maximum on interstates and 13 feet and 6 inches in height on secondary roads.

Routine heavy haul and oversize trucking permits in Arizona.

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

Length: 120 feet maximum or proceed to super load section.
Weight:  250,000 pounds maximum (Class C if over or see superloads). Single axle is 28,000 pounds maximum. All tandem, tridum, trunnion and quadem axle configurations depend on axle spacings and tire sizes. Gross weight maximums: 5 axles is 104,000 pounds, 6 axles is 108,000 pounds, 7 axles is 117,000 pounds. The permissible maximum weights depend on the number of tires combined with the overall distance between each of the axles. Spacings on axles are a little bit tricky in this state. The Arizona DOT permits office will consider a number or factors but it’s primarily about the bridges which could require a route survey if extreme weights are involved. If weights are excessive and trailer capabilities are even close to short of maxing out, forget it! Pavement, structural and stress testing results will govern your overall permissible capabilities.
Width: 14 feet wide maximum or file under super load.
Height: 16 tall maximum or file under super load.
Overhang:  3 feet of front or 6 feet off of the rear or any configuration that is in excess of 75 feet. They could require you to use a stretch trailer before allowing you to proceed under super load provisions.
Notes: These above routinely permitted shipments will need to be filed as class “A” permits. Class A permits are anything under 120 feet in length, 14 feet in width, 16 feet in height or under 250,000 pounds overall. Maximum speed is set at 55 mph for all oversize/overweight shipments.

Super load information for Arizona.

Arizona state DOT will classify your shipment as a super load if you are in excess of any of the following:

If a shipment exceeds any of the following it is classified as a superload and will require a class C permit. Class C permits are “super load permits”. If any shipment is in excess of 120 feet in length or 14 feet in width or 16 feet in height or 250,000 pounds in weight it is classified as a super load.
Notes: For mobile home shipments and more class C permit information expand the file just below.

2021 Federal Bridge Formula Weights Explanation.

2021 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.

Do I need a trucking permits? Legal load limits.

Ohio maximum load limits until a trucking permit is required:

Length: The Ohio DOT has no maximum length set that we know of. Trailer length is set at a maximum length of 53 feet. If the shipment is over 90′ in length (combined) 1 pilot car (escort vehicle) is required.
Height: 13 feet 6 inches is the maximum allowed shipping height as per Ohio DOT without a permit.
Width: 8 feet 6 inches is the maximum width allowed to travel on Ohio roads.
Weight: 80,000 pounds maximum weight (GVW) 20,000 pounds on any single axle, 34,000 pounds on dual axles, 48,000 pounds on tridum axles.
Overhang: 53 feet is the maximum length. Front overhang is an issue that has not been clearly addressed by O
Notes: Definitions of weights: Overall Spacing: Distance center to center, to the nearest foot between extreme front and rear-most axles of vehicle or combination of vehicles, or any internal axle grouping. Spacing: Distance center to center, to the nearest foot, to an adjacent axle.

 

Some divisible loads may be permitted to travel is less than 150 miles. Transporting metal coils such as aluminum, copper, steel have different laws, basic info is 3 (or fewer) coils are deemed “nondivisible loads” (as per OH NonDivisible and per Ohio 5501:2-1-01 (Q).

Routine oversize and heavy-haul trucking permits.

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

Length: Anything over 90′ will require a pilot car/escort vehicle.
Width: 14′ is the maximum width considered on routine issued permits. Routing of course is the restricting factor so if you may qualify for up to (our approximation) 16′ routinely depending on your desired route.
Height: 14′ 6″ in the maximum for routinely issued permits. Of course routing is the qualifier. If your shipment is 14′ 6″ or over you will be required to have a high pole escort.
Weight: Single axle: 29,000 lbs. Tandem axles: 36,000 lbs if axle spacing is a minimum of 4′ 1″ and up to a whopping 50,000 lbs if  your axle spacings are more than the 4′ 1″ but not more than 16′. Tridem axles: 60,000 lbs maximum if your axle spacing is less than 4′ and 53,000 lbs if your axle spacing is more than 4′ but less than 16′. Quadem: 60,000 (as long as GVW is not over 120,000 lbs). 5 axles (single-tandem-tridem): 29,000 lbs – 46,000 lbs – 46,000 lbs = 121,000 lbs maximum total per group of axles.  However; in order to do this you have to have a minimum of a 51′ outer bridge and a 36′ inner bridge in order to heavy haul on a 5 axle setup. 6 axles: (single-tandem-tridum); 29,000 lbs, 46,000 lbs, 53,000 lbs = 128,000 lbs total maximum per group of axles. 7 axles: (single-tridum-tridum); 29,000 lbs – 53,000 lbs – 53,000 lbs = 135,000 lbs total maximum weight allowed. 8 axles: (single-tandem-tandem-tridum); 29,000 lbs – 46,000 lbs -46,000 lbs – 53,000 = 174,000 lbs maximum for this kind of group setup.
Overhang: We have not located any information on routinely permitted overhang. So, we have to assume that as long as you do not want to overhang more than 1/3 of the overall length of the item being shipped you can probably get a routine permit. When you wish to exceed this basic rule (more than 1/3 overhang) you create a potentially dangerous situation. If you have any knowledge on routine overhang in Ohio please share it with others below.

80,000 pounds maximum weight (GVW) 29,000 pounds on any single axle, 36,000 pounds on dual axles, 60,000 pounds on quad axles.

Notes: As long as the GVW is not over 120,000 lbs you can use a tridem or quadem setup but you are required to have the minimum of 4′ 1″ spacing in your axles. You can go up to 132,000 lbs on a 7, 8 or 9 axle setup for your steering configuration plus 2 tridem or quadem axle groups. Please see more in superloads section below.

Notes: Definitions of weights: Overall Spacing: Distance center to center, to the nearest foot between extreme front and rear-most axles of vehicle or combination of vehicles, or any internal axle grouping. Spacing: Distance center to center, to the nearest foot, to an adjacent axle.



Ohio superloads.

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

Length: Depending on your route you probably will not have any problems with length in Ohio unless you are over 160′ overall. Ohio DOT has no set limitations on length so you may not even qualify as a supleroad.
Width: Again depending on the route you intend on taking unless you are over 18′ in width you may not qualify as a superload by the Ohio DOT. While they are not too keen on wideload shipments they tend to look at these on a case by case basis which is all dependent on your routing. In some areas you 16′ may qualify you as routine. If your shipment is over 18′ in width you will be classified as a superload. We welcome your comments below.
Height:
If you are over 14′ 6″ in the state of Ohio you will be required to have a high pole escort (pilot car) in front of you the entire route. Ohio DOT may require that you notify any/all utility companies that manage obstructions on your route before you are permitted to move. It’s all about your routing in Ohio as we are sure you are learning however, Ohio DOT is very knowledgeable and you have to give them credit for that. We feel they should be a little more lenient on height issues or have published routes for routine permits  but maybe they have future plans.
Weight: For superload configurations that are in excess of 120,000 lbs gross you will most likely be required to reduce your configuration by using a jeep. Your overall minimum axle spacings will need to be no less than 65′ with the inner bridge no less than 51′. See “routine trucking permits” above for more information about required axle group spacings as your groups need a distance of no less than 4′ 1″ between each.
Overhang: Use the rule of 1/3. Read more above in “routine trucking permits”

Legal travel times for oversize and heavy-haul loads.

Travel times and restrictions:

Basic travel times:
The basic rule of one half hour before sunrise and one half hour after sunset applies (example; travel start time is at 1/2 hour before sunset on approved days). Ohio DOT regulations travel times are complicated due to population/traffic density consideration. ALWAYS REFER TO YOUR PHYSICAL PERMIT BEFORE COMMENCING MOVEMENT. If your shipment is over 12′ in width you are NOT allowed to travel in the list of counties and within a 25 mile radius of the cities listed below between the hours of 6:30 AM until 9 AM and from 4:30 AM until 6 PM Monday thru Friday and on Fridays,  Saturdays and Sundays you may not travel after 3 PM during the days between April 1st until November the 30th.

Holiday movement:
You are permitted to travel on the following holidays with the above rules in mind; Columbus day, George Washington’s birthday, Martin Luther King day and Veterans day. You are prohibited from traveling on the following holidays; New Years day, Memorial day, Independence day, Labor day, Thanksgiving day and Christmas day. The Ohio DOT permit offices are closed on all of these days.

When pilot cars of 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:

Width:
2 lane roads:

  • 13 feet requires 1 pilot car.
  • 14 feet and 6 inches requires 1 pilot car and 1 escort vehicle.
  • 16 feet requires 1 pilot car and 1 escort vehicle and 1 police escort.

4 lane roads:

  • 13 feet requires 1 pilot car.
  • 14 feet and 6 inches requires 1 pilot car and 1 escort.
  • 16 feet and 6 inches requires 1 pilot car and 1 escort and on some routes 1 police escort.

Height:

  • 14 feet and 6 inches requires 1 pilot car equipped with a high pole.
  • 14 feet and 10 inches and over requires 1 pilot car equipped with a height pole and 1 rear chase.
  • Some routes may be required to be accompanied by 1 police escort.

Length: 1 pilot car/escort vehicle is required in the overall length of your shipment is in excess of 90 feet in length.
Width: 1 pilot car/ escort vehicle is required for shipments in excess of 13′ wide. If on a 2 lane road the pilot car needs to be in the lead position and on 4 lane roads the rear chase position is required. If the width is greater than 14′ 6″ wide then you are required to have 1 front and 1 rear pilot car/escort vehicle.
Height: If the height of you shipment is in excess of 14′ 6″ in height you are required to have 1 front/lead pilot car/escort vehicle with a height pole. If the shipment is in excess of 14′ 10″ in height you are required to have 1 front pilot car/escort vehicle equipped with a high pole and 1 rear chase pilot car/escort vehicle displaying a “OVERSIZE LOAD” banner. See banner/sign specifications and requirements below in “pilot car certifications & requirements” section.
Weight: There are no immediate pilot car or escort vehicle requirements for shipments that are overweight. As long as the shipment is able to maintain the minimum speed limit requirements escort is necessary. This may not be applicable towards superloads which is on  case by case basis.
Overhang: Overhang, if excessive is reviewed on a case by case basis. If your shipment is overhanging by less than 1/3 of it’s length (1/3 meaning the overall measurement of only the item being shipped) you may be required to use a flag or amber light on the rear as long as the overall length of your shipment is not excessive and overhang is not either, ie; no more than 10′ (this is only a assumption and you must clarify your requirements with the Ohio DOT).
Note: If you are required to have only 1 pilot car/escort because your shipment is only 13′ wide but your shipment requires you to have 1 pilot car/escort because you are over 90′ in length you are considered a “combination” shipment and will be required to have 1 front and 1 rear pilot car/escort vehicle.

 

Pilot car certifications & requirements.

Pilot car (escort vehicle) certifications and requirements of the Ohio DOT:

Pilot car and escort vehicles operating in the state of Ohio are mandated by the Ohio DOT to have an amber light mounted on the roof of the vehicle. The amber light must strobe or flash and be clearly visible from a 360 degree angle from a distance of no less than 500′. The vehicle is required to have a single roof mounted sign or a front/rear sign (depending on if operating as a lead or chase vehicle) that is no less than 5′ in length and 12′ in height with letters no less than 8″ in height that are a minimum 1″ in thickness. The sign must be yellow in color with black lettering and state the nature of the load being shipping, either “OVERSIZE LOAD” OR “WIDELOAD”. All pilot car or escort vehicles are required to be equipped with a CB radio or powerful 2-way communication device that enables them to be in constant communication with all parties working in the movement. Pilot car vehicles are required to have a hand held paddle sign that states the words “STOP on one side and “SLOW” on the other is case traffic needs to be controlled.

Note: It is only our professional 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 red safety colored flag with a handle no less than 18″ square, 3 reflective emergency road triangles or 18″ traffic cones, 8 burning road flares, 2 OVERSIZE LOAD banners (yellow with black lettering) and a safety colored (red, orange, yellow or lime green) vest, jacket or shirt (used while directing traffic).

Shipment, truck and trailer markings.

Truck, trailer and shipment required markings with banners, signs and flags by Ohio DOT:

A strobing or flashing amber light that is visible from 360 degrees from a distance of no less than 500 feet is required to placed on the highest point of the cab of the tractor trailer. Signs/banners that indicate the nature of the shipment, “OVERSIZE LOAD” OR “WIDELOAD” are required to be placed at the overall front and rear of the shipment. These banners must be yellow in color with black lettering and not less than 7′ in width and 18″ in height. Letters must be a minimum of 10″ in height with a 1 1/2″ line thickness. Safety flags must be mounted at the 4 outer most corners of the overall shipment and be no less than 18″ in length in either direction and be safety red or orange in color. If the shipment protrudes in any direction like overhang additional flags are required. You may be required to place flashing or strobing amber lights on any protrusions as well.
