Vehicle braking distance is defined as:

• A. Distance from brake to full stop
• B. Distance from hazard to brake
• C. Distance before braking anticipated
• D. Distance from brake application to full stop

Answer: (D)

Braking distance is the portion of stopping distance that starts when you apply the brakes and ends when the vehicle comes to a stop. It marks the moment braking forces take over, so the distance traveled during that time depends on speed, road conditions, and brake/tire efficiency. The phrase that defines braking distance this way—starting at brake application and ending at full stop—is the precise description of the braking phase. Other options describe what happens before braking begins (perception/decision time) or use wording that doesn’t clearly specify when braking starts, which would mix in reaction or pre-braking travel rather than the actual braking phase.
