ROAD SAFETY
Speed changes the outcome.
Explore why lower speeds protect pedestrians and school communities.
30 km/h
1.0× relative impact energy
Compared with the same vehicle at 30 km/h. Kinetic energy increases with the square of speed. This is a physics illustration, not a prediction of an individual pedestrian’s survival.
Use 30 km/h or lower limits where vehicles mix with pedestrians and school children, with safe crossings and traffic calming. Follow posted national highway limits and slow further in poor visibility.
