Which of the following is equal to the stopping sight distance?

(braking distance required to come to stop) + (distance travelled during the perception-reaction time)
(braking distance required to come to stop) - (distance travelled during the perception-reaction time)
(braking distance required to come to stop)
(distance travelled during the perception-reaction time)

Correct answer: (braking distance required to come to stop) + (distance travelled during the perception-reaction time)

Solution

The stopping sight distance is the total distance a driver needs to safely stop their vehicle, which includes both the distance traveled during the time it takes to perceive a hazard and react, as well as the distance required to brake to a complete stop.
