From the driveway to the highway, get all the snow off your car.
Getting your car out of the snow and on the road can be a pain, but it's an important aspect of driving safety.
Keep your windows clear: Don’t start driving until the windows are defrosted and clean -- even if you’re only going a short distance. Brush all the snow off your car and don't forget the roof! In fact, failing to clean off your car can be illegal. More than that, it can be dangerous to cars behind you: You don't want a block of ice the size of a mattress flying off your car into traffic.
Also, before you hit the road, make sure the exhaust pipe isn’t clogged with snow, ice, or mud. A blocked exhaust could cause deadly carbon monoxide gas to leak into the passenger compartment with the engine running.
