Show answer and explanation

Correct answer: The human factor, the road and environment factor, and the vehicle factor.

Three factors can play a role in a crash: the human factor, the road and its surroundings, and the vehicle. The human factor has the greatest influence, but the other two also cause crashes, for example through a tire blowout or very thick fog.
