Question 4728

Traffic accidents are significantly influenced by..

  1. the driver and the road only.
  2. the driver, the road, and the vehicle.
  3. mainly the road and the vehicle.
Show answer and explanation

Correct answer: the driver, the road, and the vehicle.

Three factors influence crashes: the human factor, the vehicle, and the road and its surroundings. The human factor plays a role in most crashes, but the other two also matter. That is why naming only the driver and the road, or the road and the vehicle, is not enough.
