Why should you clear snow and ice from the entire vehicle, including the trailer roof and lights, before driving?
- A.Only the windshield needs clearing by law and practice
- B.Roof snow melts safely at speed
- C.Chunks blowing off can blind or strike following drivers, and covered lights and reflectors hide your vehicle from others
- D.Covered lights are brighter in snow
Correct answer
C. Chunks blowing off can blind or strike following drivers, and covered lights and reflectors hide your vehicle from others
Why
Ice leaving a trailer roof at highway speed is a dangerous projectile, and snow-covered lamps erase the signals other drivers depend on. A full clearing, including marker lights, mudflaps area, and the roof where safely accessible, is part of the winter pre-trip.
