7 Things You Need to Know BEFORE Driving the Coquihalla and High Mountain Passes

Coquihalla safety tips

Coquihalla, Rogers Pass, Bear Pass, Pine Pass…are you ready?

If you live on the Coast, you may not travel BC’s mountains very often. We’ve noticed a number of those living in those areas aren’t always ready to go from wet Lower Mainland winter to snowy BC Interior/ Northern winter.

Sure those mountains make the perfect backdrop to all those Hollywood North movies; and of course, they’re gorgeous looking when all covered in a fresh dusting of snow. Don’t be deceived by that beauty, though. When travelling, they can change pretty dramatically when you come face to face with them.

If you are planning on leaving the Lower Mainland and travelling into the mountains this winter, you need to plan ahead. To make safety a priority, you must know as much as you can about High Mountain Passes (there are more than 50 in BC, by the way) and what they mean to you.

As you could probably guess, high mountain passes are roads built on high mountains. But there’s more to those mountains than just mounds of rock. They are living, breathing environments, subject to a diverse range of weather that can change at a moment’s notice.

It’s not uncommon for a beautiful day to turn into a raging snow storm in a matter of minutes. The coastal mountains of BC are the first in line for weather systems moving in off the Pacific, and this close proximity to the ocean can translate into high volumes of water coming down on the mountainside. And, the higher you go in elevation, the colder it gets, meaning you need to be prepared for the “snow to hit the fan.” (I’m pretty sure that’s the saying)

But don’t worry – if you plan ahead, that risk of dramatic weather change won’t put too much of a wrinkle in your plans. Here’s what you need to do before you head up the hill:

  1. Make sure your car has proper tires. For severe winter conditions for passes such as the Coquihalla, winter tires with the mountain snowflake logo provide the best performance. At the very least M+S tires with a tread depth of at least 3.5mm must be used. Check out our winter tire site for more information.
  2. Make sure both your headlights and tail lights are working
  3. Make sure your car has a full tank of gas. There is nothing worse than being stuck in a snowstorm because of an accident ahead and watching your last gas fumes drift away, leaving you chilling on a cold and dark mountainside.
  4. Dress the part. Pack warm clothes, boots, gloves and blankets. Keep them in your trunk. Always.
  5. Bring food and water. Seems like a simple thing, but those basic things will keep you going if the weather turns sour and you are stuck in your car.
  6. Check DriveBC. DriveBC has road conditions, events and webcams of those mountain passes, so that you can see what is happening before you go and help you decide if Uncle Bernard’s reunion is really worth the trip. Current weather from ministry Road Weather Stations and Weather Forecasts from Environment Canada (including High Elevation Travellers’ forecasts for some of the prominent mountain passes) are also available on DriveBC.
  7. Carry a cell phone.

If the road is wet or has snow on it then you should be driving below the posted maximum speed limit. When conditions are anything but ideal you should be slowing down.

Two of the best things about living in Vancouver are the ocean and mountains. But now that you know a little bit more about those mountains, we hope that you will take some time to prepare yourself for the high mountain road ahead. Safe travels!

    • Hello Barbara,

      While weather on the Coquihalla during the summer is typically fair – summer storms can bring rain and even snow to high elevations. The tips given in this blog are valuable during the summer and winter and as always, please remember to check DriveBC for up to the minute road conditions and events.

  1. Not sure if anyone mentioned it and I might of overlooked it but getting a BCAA premium card might pay off too.
    Check all fluids, thermostat, belts, hoses, alternator, battery and put a piece of cardboard in front of your grill or radiator if it’s too cold for your car engine to stay warm.

  2. Interesting site for people unused to winter driving. I’d sure love to see the words “SLOW DOWN” written somewhere in capitals. I know it’s mentioned above but in such a pleasant way I wonder if it will register. So many people do not know black ice is hard to see but very easy to lose control on and don’t seem to even know enough to check it out. Bare & wet can often be icy. Why not add a winter speed LIMIT when conditions are treacherous? 120, 110 and even 100 k/p/h are too fast much of the time and especially at night.

  3. This is just straight up common sence shit why not tell ppl how to dreal with the driving conditions you don’t even mention that you should carry blankets and a flat nose shovel and some kind of sand or gravel bag to help you out in a bad situation like give ppl info that is more useful then a picture …
