Commercial vehicle operators are required to carry chains on most routes in B.C., as indicated by roadside signs. Chains are not required on the Lower Mainland and most of Vancouver Island.
Type of Winter Tires:
Drivers should use tires marked with either the M+S (mud and snow) or mountain/snowflake symbol, in good condition with a minimum tread depth of 3.5 millimetres.
The best traction on snow and ice and in cold weather is offered by tires marked with a mountain/snowflake symbol on the sidewall.
Drivers driving on designated B.C. highways without winter tires in good condition can receive a fine of $121. Commercial vehicles bypassing the active chain up area can receive a fine of $598 and commercial vehicles that do not carry chains when/where required are subject to a fine of $196.
