How does driving at high speed affect a vehicle's road holding?

- B The road holding ability of the vehicle is reduced.
- C The wheel alignment keeps the tyres in full contact with the road.

Show answer & explanation
Correct answer: The road holding ability of the vehicle is reduced..
Driving at high speed is a factor that affects road holding. At higher speeds the airflow under a vehicle reduces tyre grip on the road and when you are approaching a bend or corner; the momentum of the vehicle makes it more difficult to change direction.
