Your vehicle is your lifeline during winter - and your biggest liability if it is not prepared. Heavy snow demands more than all-season tires and optimism.
Essential Vehicle Maintenance
Tires
Winter tires outperform all-season tires below 45�°F, improving stopping distance by 25% or more on snow and ice. Check tread depth - 4/32 inch minimum, 6/32 inch recommended for winter driving. Verify tire pressure monthly; cold air reduces pressure.
Battery
Batteries lose capacity in cold weather. Have yours tested before winter. If it is more than three years old and struggles on cold mornings, replace it proactively.
Fluids
Use winter-grade washer fluid rated to -20�°F or lower. Verify antifreeze concentration protects to your region's lowest expected temperature. Change oil according to manufacturer cold-weather specifications.
Wipers and Visibility
Install winter wiper blades. Clear all snow and ice from windows, mirrors, lights, and the roof before driving - roof snow slides onto windshields and creates hazards for vehicles behind you.

Driving Technique in Heavy Snow
Accelerate and decelerate gradually. Increase following distance to 8 - 10 seconds. Avoid cruise control on slippery surfaces. If you skid, steer in the direction you want to travel without slamming brakes. Use our Braking Distance Calculator to understand stopping distances at your speed.
When Not to Drive
If our Driving Safety Calculator scores below 40, postpone non-essential trips. No destination is worth a collision on an icy road.
