Before driving after snowfall, which surfaces should be cleared?
Correct answer: The entire vehicle, including windows, lights and loose snow on the roof and hood.
Why
Clear snow and ice from the entire vehicle before driving. This includes windows, headlights, signals and taillights, and snow on the roof or hood that could slide or blow into a driver’s view. Working wipers do not replace clearing accumulated snow.
