Dimensional Permit Condition for Provincial Highways


This is a basic guide for permits that are required for the movement of loads exceeding the legal limits. The information provided is subject to The Highways and Transportation Act, 1997 and "The Vehicle Weight and Dimension Regulation". Where conflicts may arise, this information will be superseded by the appropriate legislation.

The prime concern when issuing permits is the safety, convenience of the public and protection of the province’s highways and structures. Special precautions are required when vehicles are allowed to travel while exceeding legal weights and dimensions.

Permits are issued for non-divisible loads based upon bridge and highway capacities. Permits for overweight are issued at 10 kg per mm width of tire on the steering axle and at 9 kg per mm on all other axles. Operators requiring permits for extremely heavy loads should apply for these permits well in advance to avoid delay, as time is required to review structural capacities along the desired/requested routes.

TRAVEL RESTRICTIONS

Unless otherwise specified on the Permit:

No Travel permitted for loads or vehicles exceeding 3.35 m (11 ft.) wide or 25.0 m (82 ft.) long:

Direct crossing of a Provincial Highway is allowed on Sundays and Public Holidays if a flagperson is in attendance during the crossing.

Overdimensional loads restricted from travel on Fridays at 3:00 p.m. may resume travel at 12:00 midnight providing the load does not exceed the maximum dimension for Night Travel, as identified below.
