Bumpers are protective structures found on vehicles, designed to absorb impact during collisions. They are typically made of plastic, rubber, or metal and are located at the front and rear of a car. Bumpers help minimize damage to the vehicle and protect passengers by reducing the force of an impact. In addition to their safety function, bumpers often house other components, such as sensors and lights. Modern bumpers may also include features like parking sensors and cameras to assist drivers in maneuvering. Overall, bumpers play a crucial role in vehicle design and safety.
