Correct answer

Reaction time.

Reaction time is defined as the interval that elapses from when a driver perceives a hazard to the moment they initiate a physical response, such as braking or manoeuvring the vehicle. This time includes two main components: perception and decision. First, the driver must identify the hazardous situation, and then decide how to respond. This time varies between individuals and can be affected by several factors, such as fatigue, attention, mood, the use of medicines or substances, and driving skills.
