WebApr 30, 2024 · Stopping Sight Distance. Stopping Sight Distance (SSD) is the viewable distance required for a driver to see so that he or she can make a complete stop in the event of an unforeseen hazard. SSD is made up of two components: (1) Braking Distance and (2) Perception-Reaction Time. Forces acting on a vehicle that is braking. WebThe following distanceequals your reaction distance plus your vehicle’s braking distance at different speeds.
