Use Winter Tread Tires or Carry Chains
The province of British Columbia has not yet mandated that only true winter tread tires be used during the winter months on our highways. If you pass a sign requiring the use of winter tires, currently both all season (marked M+S on the sidewall) or true winter tires (marked with the mountain and snowflake symbol on the sidewall) qualify for compliance.
You are no longer allowed to carry tire chains in lieu of having winter or all season tires fitted.
Remember, an all season tire is designed to be a compromise and operate in both summer and winter. It is not designed principally for winter use and may not be your best choice for safety.
Should you choose not to follow the advice on the sign, police may prevent you from traveling further until you are in compliance. They may also choose to issue a traffic ticket that carries a penalty of $121 and 2 points, or about the price of a good winter tire or set of chains.
