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 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.

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.

However, vehicles that are not exceeding 10’6″ wide or 16 feet tall or 85 feet and linked total may travel Monday through Saturday during daylight hours. 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.

Our research has turned up very little about New York state frost and thaw laws. Since a special permit is required in order to move a shipment the NYDOT determines the required route or denies the request until a later date. This makes projection for logistics providers difficult. However you may wish to visit their website: https://www.dot.ny.gov/nypermits/special-hauling-permits

Oversize restrictions.

There are no restrictions (we are aware of) for oversize loads during the winter and spring thaw months. This is not to suggest that no maximums will be imposed at any given time. Be sure to check with the NY DOT load permitting office for clarification if you plan on transporting a oversize object during the winter and spring seasons.

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.

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. For shipments over 4.45 meters (14′ 7″) wide require 1 front pilot car/escort and 1 rear pilot car/escort on single lane roads. If your shipment is in excess of 5.5 meters (18′) you are required to have 1 front and 1 rear pilot car/escort vehicle on all roads.
Height: Alberta does not normally use pilot cars with high poles as they have designated routes for shipments that are over height. You can view the routes on the Alberta DOT high load corridor page located here.
Weight: 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 Alberta DOT.
Overhang: If you have overhang that is over 6.5 meters (21′ 4″) you will be required to have 1 rear pilot car/escort vehicle. If your shipment overhang is in excess of 9 meters (29′ 6″) you will be required to have 1 front and 1 rear pilot car/escort vehicle.

Pilot car requirements.

Pilot car (escort vehicle) requirements for operating in Alberta province are as follows:

Pilot car/escort vehicle operators are NOT required to take any sort of DOT certification course in order to operate in Canada. Your vehicle is required however 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 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 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 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.

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.

Overweight shipments.

No shipment overweight (no matter what axle configuration) is permitted to travel during the spring thaw. It should also be noted some shipments may be required to reduce load weights by 25-35% on state roads during the spring thaw months. If your have more than 11 axles total you will not be permitted to leave or enter Michigan during the spring thaw months.

Oversize shipments.

Any shipment in excess of 14′ in width is not permitted to travel during the spring thaw months.
