- presses the brake pedal until the vehicle comes to a stop.
- perceives a hazard until the vehicle comes to a stop.
- perceives a hazard until they act on the vehicle's controls.
Show answer and explanation
Correct answer: perceives a hazard until they act on the vehicle's controls.
Reaction time runs from when you notice a hazard until you use the controls, for example by pressing the brake or turning the steering wheel. In the image, it starts when the driver of the red car sees the girl with the ball next to the curb. From when you press the brake until you stop counts as braking time.
