Quebec Spring Thaw Weight Restrictions – Updated Dates

Each year, Quebec reduces weight allowances during spring thaw to reduce highway damage.  The province is divided into three zones – with Zone 1 representing most of southern Quebec, and Zones 2 and 3 progressively further north.  The following 2023 dates, as provided by the Ministère des Transports, are subject to revision depending on actual weather and road conditions.  Updates to the predicted dates can be found at:

Zone 1 – Monday March 20 to Friday May 19, 2023 (inclusive)

Zone 2 – Monday March 27 to Friday May 26, 2023 (inclusive)

Zone 3 – Monday March 27 to Friday May 26, 2023 (inclusive)

A map of the three zones as well as spring thaw weight allowances can be found in Quebec’s ‘Load and Size Limits Guide’:
