A speed hump is a gently raised section of road, commonly made of asphalt or rubber. It is designed to reduce vehicle speed, especially in areas with heavy pedestrian traffic or where safety is a concern. Speed humps are typically used in residential neighborhoods, parking lots, or near schools, where they encourage drivers to slow down without causing a sudden bump. Unlike speed bumps, which are shorter and more abrupt, speed humps are longer and less steep, allowing vehicles to pass over them more smoothly while still reducing speed.
