BDifficulty 2/5

Can a driver's reaction time increase?

Correct answer

Yes, depending, for example, on their physical condition.

Yes. Reaction time varies with attention, physical condition and circumstances. Alcohol, sleepiness and fatigue can lengthen it; excessive heat can promote tiredness and inattention. Substance effects are not identical in every case. It is not always below one second, and distance travelled during that time increases at higher speed.
