A winter trip to Kamloops starts with the route as well as the destination. British Columbia's tire requirements have specific dates, markings, and tread limits, while construction can add time to an eastbound journey on Highway 1. It helps to separate three questions: whether the vehicle meets the rules, what conditions are reported for the trip, and how much time to leave in the day's schedule. Meeting an equipment requirement does not turn a travel estimate into a guarantee.
When Winter Tires Are Required
The Province's designated winter tire and chain routes guidance requires winter tires or chains on most B.C. routes from October 1 to April 30. On selected highways outside mountain passes and high-snowfall areas, requirements end March 31. Do not assume that the shorter season applies to an entire journey simply because one part of the route is outside a mountain pass.
Regulatory signs identify the designated routes. The province can restrict travel at any time of year depending on conditions, and non-compliant motorists may be turned away and fined. Cities, municipalities, and private roads, including ski hills, may have their own rules for winter tires, chains, or traction devices. Check the requirements for the whole itinerary, including its final approach, rather than treating a provincial highway rule as the only rule that matters.
What Counts as a Legal Winter Tire
The Province's passenger-vehicle tire requirements define a legal winter tire as having at least 3.5 millimetres of tread and either an M+S marking or the three-peaked mountain/snowflake symbol. Both the tread depth and the marking matter. The definition applies to standard passenger vehicles and four-wheel or all-wheel-drive vehicles alike.
M+S is the minimum legal marking. The province says tires bearing the mountain/snowflake symbol provide better traction on snow and ice, recommends them for cold-weather driving, and recommends carrying chains for extreme conditions. Summer tires are not permitted during designated winter months. Putting chains on summer tires does not make them an acceptable substitute for legal winter tires on signed B.C. highways. Read the route guidance together with the passenger-vehicle definition rather than assuming that any tire-and-chain combination qualifies.
Visitors and Rental Cars
Coming from another province or country does not create an exception. The Province's visitor and rental-vehicle guidance says out-of-province passenger and commercial vehicles must follow B.C.'s winter tire and chain requirements. M+S and mountain/snowflake manufacturer ratings are consistent for tires sold in North America.
Most rental vehicles have M+S tires, according to that guidance, but this describes the usual equipment rather than confirming the tires on a particular car. The province advises discussing tire options with the rental provider, especially for travel beyond Greater Vancouver or Greater Victoria, and identifies mountain/snowflake tires as providing the best winter traction. Make tire type and tread depth explicit parts of the vehicle check before planning a route through the interior.
Highway 1 East: Construction and Travel Times
The Province's September 14, 2026, Highway 1 travel estimates give the following regular journey times and anticipated construction allowances between Kamloops and the Alberta border. These are dated estimates, not live traffic information.
| Section | Regular travel time | Construction allowance |
|---|---|---|
| Kamloops to Salmon Arm | 75 minutes | 10–20 minutes |
| Salmon Arm to Revelstoke | 81 minutes | 30–40 minutes |
| Revelstoke to Golden | 103 minutes | 30–40 minutes |
| Golden to the Alberta border | 35 minutes | None listed |
The total anticipated construction delay was 70–100 minutes. The table excludes unanticipated emergency and maintenance work and the separate closure notices on the provincial page. An allowance belongs alongside the regular travel time; it does not replace it. Leave space for rest and meal stops separately, and check DriveBC for the departure-day situation.
Completed work and remaining delays can coexist along the corridor. The Province's July 20, 2026, completed-project list records Chase West as complete in 2024 and Chase East in 2026. Quartz Creek and Donald Bridge were completed in October 2024, and Kicking Horse Canyon Phase 4 was completed on July 31, 2024. Completion of those sections does not describe every other section's status.
The Ford Road to Tappen Valley Road project page, dated September 21, 2026, says the highway and surrounding frontage roads were open at full design speeds. It still listed October 31, 2026, as scheduled completion. A road operating at its design speed and a project's scheduled completion date are different pieces of information.
Before You Set Out
Use the tire dates and markings to check equipment, then use current road information to decide how the journey fits the day. Keep the September 2026 construction allowances in their dated context. The province directs travellers to DriveBC for the latest highway information; a saved estimate cannot establish whether a closure or additional delay applies when you leave.
For a shared trip, agree who will check the route and vehicle details and who will pass along any change in departure time. Build flexibility into the schedule before committing to stops along the way. A useful plan brings the route requirements, the vehicle's actual tires, the latest road report, and the time available into the same conversation.
