2023 British Columbia Oversize and Overweight Load Trucking Regulations, Permits, Laws, Rules, and Limitations
Oversize Legal Load Limits in British Colombia
British Columbia legal load limits:
- Length: 14.65 meters (48.06′) from the kingpin to the rearmost 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 rearview 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 tridem axles. A tridem pole trailer: gross weight on any two adjacent axles in a tridem 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; the reference link below in “notes” under “maximum gross weight”. See also “comments” at the bottom.
- 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.
NOTES: No matter what a permit states, if 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.
Routine Trucking Permits in British Columbia
Oversize and overweight trucking permits that are routinely issued by the British Columbia DOT :
- Length: 27.5 meters (90 feet, 2, and 43/64 fourths on an inch) is the maximum length for a routine permit in British Columbia.
- Width: 4.4 meters (14 feet, 5, and 15/64 fourths of an inch) is the maximum you will get from British Columbia 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 the 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.

When Are Pilot Cars Required in British Columbia?
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 are required.
- Width: For 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 of 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 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.
