The correct answer, which describes the distance a vehicle travels from the moment the driver spots a hazard until the decision is made to apply the brake, is reaction distance. This term specifically refers to the time and distance it takes for a driver to recognize a potential danger and respond to it by engaging the braking system. Reaction distance is influenced by several factors, including the driver’s alertness, the conditions of the road, and vehicle speed.

Braking distance, on the other hand, is the distance the vehicle covers while the brakes are actively engaged after the driver has decided to stop. Perception distance refers to the distance covered while the driver is aware of a hazard but has not yet reacted, and stopping distance encompasses both reaction and braking distance combined, representing the total distance needed to come to a complete stop. Each of these definitions plays a critical role in understanding safe driving practices and the dynamics involved in responding to road hazards.
