Why Some Routes do not Require Winter Tires
B.C.
cities, municipalities and private roads (such as ski hills) may have their own bylaws or rules around the use of winter tires, chains or traction devices that may differ from provincial highway regulations.
Driving in the Lower Mainland and Southeastern Vancouver Island
Due to a more temperate winter climate in the Lower Mainland and southeastern Vancouver Island, drivers are not required to use winter tires in many areas along the coast. See the
South Coast Map for places where winter tires
are needed, such as the Malahat. Remember, you are responsible for equipping your vehicle properly for the conditions you are driving in. Many drivers choose to use M+S tires year-round.
Remember: If you plan to travel outside the Lower Mainland and southeastern Vancouver Island, winter tires are required on most highways.
