a bar that is attached to the back and front of a vehicle to reduce damage in time of an accident
A bumper is a protective part of a vehicle located at the front and rear, designed to absorb impact in case of a crash. It helps reduce damage to the vehicle by absorbing some of the force during a crash. Bumpers are typically made of plastic, metal, or fiberglass and may include additional features like lights or sensors. They are important for safety, as they help protect both the vehicle and its passengers from minor accidents, and they also improve the vehicle's overall durability.
