How should I prepare a vehicle for driving under winter conditions?
Driving in winter weather - snow, ice, wet and cold - creates a great challenge for vehicles and drivers. Keeping the vehicle in good technical repair reduces the overall chances of any mishap or disaster while driving - particularly in winter weather. To prepare the vehicle for winter driving, give it a complete checkup. Look for the following:
Tires
The traction between tires and roadway determines how well a vehicle rides, turns and stops, and is crucial for safe driving in winter. Proper tire selection is very important.
- context Use four snow tires of the same type, size, speed rating, and load index for better handling, control and stability. In Canada, tires are marked with a pictograph of a peaked mountain with a snowflake. This pictograph means the tire has been designed to meet specific snow traction performance requirements and is designed for use in severe snow conditions.
- context Use all-season radial tires only in areas that receive only light snowfall.
- context Use chains or studded tires on all four wheels when you expect severe snow and icy roads. Check with your local Department or Ministry of Transportation office to see if using tire chains or studded tires is legal in the region you plan to drive through.
- context Check tire pressure and restore it to levels recommended by the vehicle manufacturer. The pressure drops about 1 psi for every 5°C (9°F) drop in temperature.
- context Check the wear of the tires. Tires have tread wear indicators or bars that are inside the grooves of the tires. When the tread is close to (within 1.5mm) or the same level as the wear indicator, replace the tire as it no longer provides effective traction.
- context Check tire balance and correct it if necessary.
- context Check wheel alignment and correct if necessary.
What should I include in a winter driving kit?
A well-stocked winter driving kit helps to handle any emergency. It should include:
- context Properly fitting tire chains.
- context Bag of sand or salt (or kitty litter).
- context Tow rope.
- context Traction mats.
- context Snow shovel.
- context Snowbrush.
- context Ice scraper.
- context Booster cables.
- context Warning devices such as reflective triangles, flares, or emergency lights.
- context Fuel line de-icer (methanol, also called methyl alcohol or methyl hydrate).
- context Extra windshield wiper fluid is appropriate for sub-freezing temperatures.
- context Roll of paper towels.
- context Flashlight and a portable flashing light (and extra batteries).
- context Blankets.
- context Extra clothing, including hat and wind-proof pants, and warm footwear. Consider bringing hand and foot warmers.
- context First aid kit.
- context Non-perishable snacks or other "emergency" food and water.
- context Matches and emergency candles - only use with a window opened to prevent the build-up of carbon monoxide.
- context Road maps.
- context "Call Police" or other help signs or brightly coloured banners.
Should I put the vehicle into neutral during a skid?
Experts agree that during a skid, it is important to reduce the vehicle's forward motion to stop faster.
Many resources that promote putting your vehicle in neutral describe the following technique:
Others promote leaving the vehicle in gear but do not apply the gas during the skid. At the end of the skid, it may be necessary to accelerate gently, or you may need to avoid an obstacle.
Using winter tires and driving at a reduced speed are more important factors that influence a vehicle's stopping distance.
- context If you're using automatic transmission, shift to neutral. However, do not touch the transmission gear if you cannot do that immediately.
- context If you're using manual transmission, declutch.
- context Disconnect the driving force on the drive wheels by doing either of the following:
