Legal Load Limits in Alberta

Below are the legal load limits by Alberta DOT 

  • 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 the steer axle. Tandem axles: 17,000 kg. Tridem 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 allowed overhangs 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 in Alberta

Here are oversize and overweight trucking permits routinely issued by the Alberta DOT:

  • Length: 52 meters (170′ 8″) is about the maximum length you can get 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 the tire you are running. Routing is 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.

Transportation of Superloads in Alberta

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 with our other viewers below. Thank you.

Permitted Travel Times and Restrictions in Alberta

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 3 pm 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 42 meters (137′ 10″) on a single-lane road you will be required to have 1 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 no 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
  • 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. Overwidth 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 affect 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 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 in Alberta

If your shipment is in excess of any of the following dimensions, 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 an 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 in Alberta

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’s 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, and Trailer Markings in Alberta

Truck, trailer, and shipment signs, banners, and flags in Alberta

All trucks 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 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.

  1. Hello, trying to find the correct information but just want some clarification. For a tractor hauling super “b” train tankers between USA and Alberta; 1) what is the length we are allowed in Southern Alberta, 2) if a permit is needed for length do we have to follow the 1/2 hour before sunrise and 1 hour after sunset rule? Thanks!

    1. Well, the max length is 23 meters per legal length with no need for a permit (see this page) anything longer is required to be permitted. For approval time purposes that are routinely issued the maximum is 52 meters long. After that, your into superload class which usually takes longer to permit and may even require a route survey.

      Also note pilot car requirements:
      “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.”

      Any shipments outside of legal dimensions must follow all curfew/travel times. All of this information is printed on the permit as well. While we offer this information on line as a guide, always follow the information printed on your permit. For any discrepancies in the information printed on the permit always contact the permit office in the province/state it was issued in.

  2. Rear Overhang rule for Alberta:
    Centre of rear axle group to end of trailer or load must not exceed 35% of trailer wheelbase (measured as Kingpin to center of rear axle group) or else it will need to be permitted.

  3. Hello I would just like to state that
    For Heavy Haul:
    Steer max is 7300kg (depending on steer tire size)
    Drives: Tandem 17000kg, Tridem 23000kg.
    Trailer: Tandem 17000kg Tridem 24000kg.

    These are the MAX LEGAL WEIGHTS before you need to permit. The province created SEASONS inwhich gives you the MAXIMUM at that time to permit.

    When you get into jeeps and booster the numbers change slightly and combination weights will come into play.

    OVERHANG is 35% of your trailer wheelbase or 6m (Whichever is shorter), you can permit up to 50% overhang though but will need to provide interals.

    1. Hello Matt,
      Can you be more specific please? How far can you stretch? What kind of deck do you have? There’s a lot of different kinds of stretch trailers that will do about anything known to man. Give us more information please. Thank you!

  4. Have a 3 ton Hino 195 Truck…client wants to transport teepee poles that are at least 20 feet long….even though flagged at the end of the poles….I told it was not safe as the only way to secure poles is with the door tied down…The other problem is the length of the poles out the back of truck…exceeds I believe 12.8 m…Is this a legal load to haul 10 km in CAlgary???

  5. I’m planning on moving a composite ultralight airplane, it’s a Quickie 1, a canard style plane. There’s no wings or tail that come off so I gotta haul it as is. Canard is 16’8″ wide and 15′ long and about 4′ high. I have a 8.5′ x 16′ trailer to haul it on. It only weighs 250 lbs.
    I can either, have the wings the length of my trailer and have the tail sticking up..making it approximately 18′ or I can load it with the wings over the sides of the trailer in a banking position where one wing is up high and the other down low past the trailers edge and close to the ground….
    So my question is which way can I move this thing from Melfort SK to Prince George BC?
    I will either need an overheight permit for the 18′ or the 16’8″ width.

    1. Tricky for cost effectiveness. A single escort with a high pole or two escorts. Since it is a relatively long run and you have multiple provinces with multiple rules and regulations I would suggest you ask them directly by calling their number on the relative “regulations” pages here on the site. A cursory guess would be the single with a height pole as 17′ 6″ is a good number for utility obstructions and you are pretty close but pretty close could injure yourself, other motorists as well as the cargo if you do have obstructions you can’t get around (like an underpass with no off/entrance ramp). So, to play it safe without guidance I would be forced to hire a lead and a chase pilot car set up but the province can route it for you and tell you exactly what you’ll need. Some state would require a lead with a height pole and a chase vehicle so whatever they say be complacent as your cargo will arrive safe and sound as long as it is properly loaded and secured. So sorry about the delay – we didn’t see your post but have since resolved this problem. We hope it went well and would love to get a reply back from you letting us know how you fared!

  6. This is a lot to figure out.
    Correct me if I am wrong, but 102 inches is fine.
    102 and above, is permit and flagged orange.
    150 and above is permit flagged and pilot cars.
    There must be a simple chart somewhere?

    1. Sorry for the delay but we didn’t see you. We’ve since got this problem solved as you’ve probably already done but for others; each province/state has it’s own individual regulations as it’s not federally mandated. That’s yet another reason why all of these “regulations” pages are required. Sorry there’s no exact chart as they are all different.

  7. 12′ X 24′ skid shack to be transported down gravel county road approximately 3 km.
    must all rules be followed when not going on pavement?

  8. i WANT TO HAUL 2 SEA CANS ON MY TRAILER. WIDTH AND HEIGHT ARE FINE. BUT I’LL HAVE 4 FT OF OVERHANG. DO I NEED A PERMIT OR EXTRA LIGHTING? I WILL BE TRAVELING DAYLIGHT HOURS.

  9. In Alberta, overwidth loads OVER 3.85 metres may travel on Friday up to 3:00 PM. Your site info on this is indicating that they may not travel at all on Friday which I believe is incorrect. Otherwise, excellent job and very helpful site.

    1. Awesome Mike. I will get that issue fully researched and corrected. Thank you so very much! Great example of how we can all help each other!!! Have a GREAT day friend!
