Safety Rubber Speed Bump

​Definition: A short, steep, raised ridge built transversely (perpendicularly) across a roadway. ​Primary Purpose: To force drivers to slow down drastically to prevent a jarring vertical jolt, discomfort, or potential vehicle damage. They are highly effective for enforcing very low speeds. ​Target Speed: Typically designed to slow vehicles to 5 to 10 mph (8 to 16 km/h). ​Physical Dimensions (General Range): ​Height: Usually between 3 to 6 inches (7.6 to 15.2 cm). ​Travel Length (Width in direction of travel): Typically 1 to 3 feet (0.3 to 1 meter). This short length, combined with the height, creates an abrupt vertical deflection.
