1. Get a grip. To have adequate snow traction, a tire requires at least 6/32-inch deep tread, according to The Tire Rack. (New passenger-car tires usually have 10/32-inch of tread.) Ultrahigh-performance “summer” tires have little or no grip in snow. Even “all-season” tires don’t necessarily have great snow traction: Some do, some don’t. If you live where the roads are regularly covered with snow, use snow tires (sometimes called “winter tires” by tire makers). They have a “snowflake on the mountain” symbol on the sidewall, meaning they meet a tire-industry standard for snow traction.
2. Make sure you can see. Replace windshield wiper blades. Clean the inside of your windows thoroughly. Apply a water-shedding material (such as Rain-X) to the outside of all windows, including the mirrors. Make sure your windshield washer system works and is full of an anti-icing fluid. Drain older fluid by running the washers until new fluid appears: Switching fluid colors makes this easy.
3. Run the air-conditioner. To remove condensation and frost from the interior of windows, engage your air-conditioner and select the fresh air option: It’s fine to set the temperature on “hot.” Many cars automatically do this when you choose the defrost setting.
4. Check your lights. Use your headlights so that others will see you and, we hope, not pull out in front of you. Make sure your headlights and taillights are clear of snow. If you have an older car with sand-pitted headlights, get a new set of lenses. To prevent future pitting, cover the new lens with a clear tape like that used to protect the leading edge of helicopter rotor blades and racecar wings. It’s available from auto-racing supply sites.
5. Give yourself a brake. Learn how to get maximum efficiency from your brakes before an emergency. It’s easy to properly use antilock brakes: Stomp, stay and steer. Stomp on the pedal as if you were trying to snap it off. Stay hard on the pedal. Steer around the obstacle. (A warning: A little bit of steering goes a very long way in an emergency. See Tip 8.) If you drive on icy roads or roads that are covered with snow, modify your ABS technique: After you “Stomp” and the ABS begins cycling — you will feel pulses in the pedal or hear the system working — ease up slightly on the pedal until the pulsing happens only once a second.
For vehicles without ABS, you’ll have to rely on the old-fashioned system: You. For non-ABS on a mixed-surface road, push the brake pedal hard until the wheels stop rolling, then immediately release the brake enough to allow the wheels to begin turning again. Repeat this sequence rapidly. This is not the same as “pumping the brake.” Your goal is to have the tires producing maximum grip regardless of whether the surface is snow, ice or damp pavement.
6. Watch carefully for “black ice.” If the road looks slick, it probably is. This is especially true with one of winter’s worst hazards: “black ice.” Also called “glare ice,” this is nearly transparent ice that often looks like a harmless puddle or is overlooked entirely. Test the traction with a smooth brake application or slight turn of the wheel.
