BDifficulty 2/5

In fog that significantly reduces visibility, which measure helps leave more room to respond to the vehicle ahead?

Correct answer

Increase the separation distance.

Increase following distance and adapt speed to visibility. Separation does not physically improve grip or remove fog, but gives more room to respond. Moisture may reduce grip; do not assume every fog condition has the same effect. Use appropriate lights and observe road markings without neglecting the rest of the road.
