Question 4973

Do all risk factors carry the same weight as a cause of an accident?

  1. No, the human factor barely plays a role.
  2. No, most accidents are due to the human factor.
  3. Yes, since the driver, road, and vehicle factors are always involved in an accident.
Show answer and explanation

Correct answer: No, most accidents are due to the human factor.

No. All three factors can occur together in a crash, but they do not carry the same weight. The human factor plays a role in between 70 and 90 out of every 100 crashes, far more than the road or the vehicle.
