What effect can drowsiness have on driving?

Correct answer

Reduce vigilance and slow reactions.

It can reduce vigilance and slow reactions, making hazards harder to detect and decisions slower. Not everyone responds by taking greater risks in the same way. Plan breaks every two hours or about 200 km and stop sooner if sleepy; do not wait to complete the interval or continue while still drowsy.
