1. SEASONAL LOAD ALLOWANCES

The Department of Infrastructure (INF) has UPDATED the seasonal load allowances on selected highway sections commencing on Monday, February 5th, 2018 at 00:00 hours. INF will enforce these load allowances in order to best protect and preserve the NWT Highway System.

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.
