Commercial Vehicle - Tire and Chain Requirements

Commercial drivers who travel outside the Greater Vancouver and Greater Victoria areas in the winter are required to carry chains, or other acceptable traction devices, and comply with all signage and regulations. Good practice is to keep chains on board at all times, and know how to install them.

Rapid changes in elevation and weather can make B.C. highway conditions unpredictable during winter months. Drivers may start a trip in sunshine but face stretches of slush, ice, heavy snowfall or compact snow along the way.

It is the responsibility for the operator of a vehicle to understand the conditions on the roads they travel and prepare their vehicle for those conditions.

Drivers must obey winter tire and chain signs throughout the province from October 1 to March 31. For select highways, including mountain passes and rural routes in high snowfall areas, the date is extended until April 30 to account for early-spring snowfall.

Chain Up Sign

Commercial trucks weighing between 5,000 kg and 11,794 kg LGVW must carry chains or acceptable traction devices, unless the vehicle is equipped with winter rated tires with the 3-peaked mountain and snowflake symbol or the M+S symbol.

Commercial vehicles 11,794 kg LGVW and greater, such as tractor trailers, are required to carry steel chains on most major highways.

Chains, Traction Devices and Additional Safety

Depending on the LGVW, vehicle type, and configuration of commercial vehicle, the requirements vary for type, number, and placement of chains or acceptable traction devices. Learn proper tire chain configurations for commercial vehicles (PDF)

Commercial Motor Vehicle Chain Configurations

Steel Chains

It is a requirement that commercial vehicles with a LGVW of 11,794kg or greater use steel link chains.  For larger vehicle configurations, they have been proven to provide superior traction and prevent lateral slippage.

Cable Chains

Cable style chains are lighter, and due to their lower profile, don’t provide the same level of traction as steel link chains.

Automatic Tire Chains

Automatic tire chains are activated and retracted from the safety of the driver's seat, eliminating the need for manual installation of chains.

Wheel Sander

On demand, a wheel sander system delivers grit in front of the tire to increase traction.

Textile Tire Cover

A textile “sock” placed over a tire improves traction. They work best on snow and ice, and at low speeds.  They degrade quickly when used on asphalt and at speeds higher than the manufacturer’s specifications.
