Does a bumper have protective casing?

A bumper is a protective casing that is attached to the front and rear of a vehicle to absorb impacts and protect the vehicle and its passengers from damage in a collision. Bumpers are typically made of metal, plastic, or a combination of both, and they are designed to absorb and dissipate the force of an impact, reducing the damage that would otherwise be caused to the vehicle. Bumpers may also include additional features such as fog lights, turn signals, and parking sensors.
