Stopping Distance

Stopping distance is how far a car travels before coming to a full stop. It combines the driver’s reaction distance and the braking distance.

What is Stopping Distance?

Stopping distance is a safety measure in transportation. It equals reaction distance (time to perceive and act) plus braking distance (time to physically stop the vehicle).

(Note: This is not directly relevant to search engines, but included as a glossary entry for completeness.)

Formula

Reaction distance: speed × reaction time.
Braking distance: depends on speed, road surface, brakes, weather.
Total stopping distance: reaction + braking.

Why It Matters

Road safety: Essential for driving tests, signage, and safety policies.
Analogies: Sometimes used in system design to describe latency or lag between action and result.

Summary

Stopping distance is the total distance needed to halt a vehicle, combining reaction and braking phases. It’s a key concept in road safety and driving education.
