A bullbar or push bumper is a device installed on the front of a vehicle to protect its front from collisions, whether an accidental collision with a large animal in rural roads, or an intentional collision by police with another vehicle. They vary considerably in size and form, and are normally composed of welded steel or aluminium tubing, or, more recently, moulded polycarbonate and polyethylene materials. The "bull" in the name refers to cattle, which in rural areas sometimes roam onto rural roads and highways.
