A speed bump is a raised area on a road or street designed to slow down vehicles. It is typically made of asphalt, rubber, or concrete and is placed in areas where drivers need to reduce speed, such as near schools, parking lots, or residential neighborhoods. Speed bumps are shorter and more abrupt than speed humps, which are designed to slow traffic over a longer distance. They help improve safety by encouraging drivers to drive at lower speeds, reducing the risk of accidents and allowing pedestrians to cross more safely.
