BC Mountain Pass Winter Driving: What to Check Before You Go
What to check before driving through BC mountain passes this winter.
BC winter driving can be very different from the weather you experience at home. A clear morning in the Fraser Valley does not always mean clear roads in the mountains. Conditions can change quickly at higher elevations, especially on routes such as the Coquihalla, Sea-to-Sky Highway, Fraser Canyon, and Okanagan Connector.
Before you leave, take a few minutes to check road conditions, confirm your tires, prepare your vehicle, and allow extra travel time for unexpected delays.
BC Winter Driving: Check DriveBC Before You Leave
For BC mountain pass winter driving, DriveBC should be one of your first stops.
DriveBC provides real-time information about road conditions, active advisories, closures, and camera feeds on major routes across British Columbia. This includes popular mountain routes such as the Coquihalla, Sea-to-Sky, Fraser Canyon, and Okanagan Connector.
A general weather forecast may tell you what conditions are expected in your area. DriveBC can give you a better picture of what is happening on the road itself.
When should you check DriveBC?
Check it on the morning of your trip and shortly before leaving. Mountain conditions can change significantly overnight.
If you are travelling later in the day, check again before starting the mountain portion of your journey.
BC Winter Driving: Make Sure Your Tires Are Winter-Ready
Your tires are one of the most important things to check before winter mountain driving.
The routes covered by your trip may be subject to BC’s winter tire and chain requirements from October 1 through April 30. Make sure your vehicle meets the applicable requirements before you leave.
Winter-ready tires are not just about following the rules. They can also provide better traction when you encounter snow, ice, or changing road conditions.
If you are unsure whether your tires meet the requirements, check the applicable BC regulations before your trip.
Give Yourself Extra Travel Time
Winter mountain driving rarely follows a perfect schedule.
Snow, poor visibility, accidents, road maintenance, and avalanche control can all affect travel times. Sections of mountain routes may also close temporarily while crews carry out necessary work.
If you have an important appointment, flight, event, or other fixed commitment, build extra time into your schedule.
An additional hour of travel time can make a significant difference when winter conditions slow traffic or cause an unexpected closure.
Carry a Winter Emergency Kit
A regular household emergency kit is useful, but your vehicle needs its own winter supplies.
For a mountain drive, consider keeping these items in your vehicle:
- Warm blanket
- Extra warm clothing
- Flashlight
- Non-perishable food
- Phone charger
- Drinking water
- Basic emergency supplies
These items can become especially useful if traffic stops because of a closure, accident, or severe weather.

Check Your Route Before You Commit
Do not rely only on the route shown by your navigation app.
Before leaving, look at the latest road information and consider whether your planned route is still practical. A route that looks normal on a map may have very different conditions at higher elevations.
Pay attention to:
- Road closures
- Active advisories
- Avalanche control
- Snow and ice
- Visibility
- Traffic delays
- Camera images
A few minutes of preparation can help you avoid a much longer delay later.
Know When to Wait or Turn Back
Sometimes the safest decision is simply to wait.
If conditions are getting worse and you are uncomfortable with the visibility, road surface, vehicle, or tires, consider stopping at a safe location and waiting for conditions to improve.
You do not have to continue just because you have already started the journey.
Mountain pass closures and travel advisories are issued when conditions create safety concerns. Take those warnings seriously instead of trying to push through.
