Seasonal Weight Restrictions

 

Weight restrictions are necessary due to current highway and weather conditions. Certain areas along NWT highways are experiencing soft surface conditions, and these restrictions are critical to protecting the long-term integrity of the infrastructure.

We recognize the challenges this may pose to your operations and appreciate your understanding and cooperation. Please be assured that the Department of Infrastructure is actively monitoring conditions. Should conditions improve, the load allowances will be adjusted accordingly.

Weight restrictions effective December 15, 2025

Winter Load Tolerance

The ‘winter load tolerance’ allowance gives the trucking industry the opportunity to increase load capacity by 500 kg per axle not including steering axles. This allowance does not permit for any accumulative overweight on: A-train, B-train, C-train or Super B-train truck and trailer configurations. The table below gives estimates for the winter load tolerances.
