Winter tire rules for Okanagan drivers (2026–27): every route and date

Which Okanagan highways need winter tires, and until when

The province marks each designated route with a regulatory sign. In the Okanagan the routes split into two groups: valley highways, where the requirement ends March 31, and mountain passes, where it runs to April 30.

From the Ministry of Transportation’s Southern Interior winter tire map, checked October 6, 2026. The Ministry doesn’t sign highways inside municipal boundaries unless a city asks, and ski-hill access roads are private roads that can set their own rules, so watch for signs on roads like Big White Road.

In practice: if you drive the Connector to the Coast, the Coquihalla to Kamloops, or Highway 1 through Salmon Arm in April, keep your winter tires on until May 1.

What counts as a winter tire

• The tire must be marked M+S (mud and snow) or carry the three-peak mountain and snowflake symbol, and have at least 3.5 mm of tread.
• Many all-season tires are marked M+S, so they are legal on these routes. The province recommends the mountain and snowflake symbol, which marks tires tested for snow traction.
• Chains on summer tires are not a substitute for winter tires on a passenger vehicle.
• Studded tires are allowed from October 1 to April 30.
• AWD and 4x4 don’t change the rule: the law is about the tires, not the drivetrain.

Fines and commercial vehicles

• $121 for driving a passenger vehicle on a designated route without proper winter tires.
• Commercial vehicles over 11,794 kg licensed GVW must carry chains: $196 for not carrying them, $598 for bypassing an active chain-up area.
• Under 11,794 kg, commercial vehicles need winter tires or must carry chains.

Buying a used vehicle this fall? Check the tires before you pay

A vehicle can look winter-ready and still fail the rule. Before you buy:

• Find the M+S or mountain-snowflake marking on the sidewall of all four tires.
• Measure tread with a gauge or a coin: under 3.5 mm doesn’t count, and a new set of winter tires can cost a meaningful share of a budget vehicle’s price.
• Ask whether a second set of wheels and tires comes with it. Many Okanagan sellers include summer or winter sets, which is worth real money.
• If you’re comparing AWD with front-wheel drive, remember AWD helps you get moving; good winter tires are what help you stop and steer.

Before you drive a pass

Check DriveBC for closures, chain-up notices and webcams on the Connector, the Coquihalla and Highway 1. Rules set the minimum; conditions on the passes can call for more.
