Bumpers are protective devices 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 lights and sensors. Modern bumpers may also include features like reinforcement bars to enhance strength and aerodynamic designs to improve fuel efficiency. Overall, bumpers play a crucial role in vehicle safety and performance.
