On packed snow, what speed adjustment is recommended?
- A.Reduce speed by about one-third
- B.Reduce speed by half or more
- C.Keep normal speed but increase following distance slightly
- D.Speed up to keep heat in the tires
Correct answer
B. Reduce speed by half or more
Why
Packed snow offers very little grip for starting, stopping, or steering, so cutting speed by half or more is the safe rule. If the surface is ice rather than snow, even that may not be enough, and stopping may be the right call.
