PERMITS: Permits valid for one trip only, duration depending on length of trip.

OPERATING TIME: Travel is permitted 24/7 when under the following dimensions: 10’6″ wide, 14’6″ high, and 82’ long. Otherwise, daylight hours only, no Sunday travel, and no travel during the summer (last Friday in June until second Monday in September) after 2:00 pm on Friday and Saturday until 4:00 am the next day.


Tractor Wheelbase: Tractor wheelbase, measured from center of steer axle to center of drive axles, cann0t exceed 244 inches on a legal load without a Long Wheelbase 30 day Permit (see table). This permit only applies for legal leads. British Columbia does not have any exceptions to the 244 inch wheelbase rule for oversize or overweight loads, except when the overall length (tractor and trailer) does not exceed 65’4″.

Tridem Drive Tractor: In the past, British Columbia has allowed tridem drive tractor to have up to a 267″ wheelbase, if they do not have any lift axles and the axles are equally spaced, but that exemption is no longer in effect.

Spread Axles: A spread axle group (over 6′ spacing) is not allowed to carry more than about 20,000 pounds total (10,000 pounds per axle). However, the POE will sell you an overweight permit for extra weight on the spread if your load is a single piece and non-reducible. Tractor wheelbase still cannot exceed 244″.

Lift Axles: British Columbia does not recognize lift axles (they are not legal). Flip axles can be used if they lock into place, are equally spaced with other axles in the group, and if overall length does not exceed 75’4″.
