A crash guard, also known as a bumper or bull bar, is a protective device installed on the front and rear of vehicles to minimize damage caused by collisions. Typically made of metal, plastic, or composite materials, they are designed to absorb the impact of a collision, protecting the vehicle’s body and its passengers.

Crash guards can come in different styles and sizes, ranging from small, low-profile bumpers to large, heavy-duty bars that wrap around the front of the vehicle. Some are designed to be mounted directly onto the vehicle’s frame, while others are attached to the front or rear of the vehicle’s chassis.

While crash guards can help protect vehicles in minor collisions, they can also pose a safety risk if they are improperly installed or if they cause additional damage to other vehicles or pedestrians in a collision. As such, some countries have regulations on the use of crash guards on public roads
