Texas Car / Permit practice question · Speed & Space Management

The total distance your vehicle needs to stop is made up of:

Answer choices

• perception-reaction distance plus braking distance— Correct answer
• braking distance only
• the length of the vehicle plus one car length
• reaction time minus braking distance

Why this is the answer

Reaction distance is how far the vehicle travels from when you perceive the need to act until you actually brake or steer, and braking distance is how far it travels from when the brakes are applied until it stops. Together they make your total stopping distance. Vehicle length does not enter into it, and the two parts are added, not subtracted.
