- reacts to a hazard until the vehicle comes to a stop.
- perceives the hazard until they react.
- perceives the hazard until the vehicle comes to a stop.
Show answer and explanation
Correct answer: perceives the hazard until they react.
Reaction distance is the distance you travel before you've responded, from the moment you notice a hazard until you react, for example by pressing the brake pedal. In the image, it's the distance the blue passenger car travels from the moment its driver sees the pedestrians in the crosswalk until they press the brake pedal. The distance it then travels before stopping is braking distance.
