A1Difficulty 3/5

According to the DGT road-safety manual, which of the human, vehicle and road factors has the greatest involvement in road crashes?

Correct answer

The human factor.

The human factor. It includes perception or decision errors, distraction, fatigue, inappropriate speed and other behaviours; it does not mean only deliberate recklessness. A crash may combine several factors, so vehicle and road condition must not be ignored. Anticipation, attention and adapting driving reduce risks.
