A bull bar, a metal structure mounted to the front of a vehicle, is also referred to as a grille guard, grille protector, or push bar. It's a popular accessory for off-road enthusiasts who want to protect their vehicles from damage caused by wildlife, rocks, or larger debris. Another synonym for bull bar is a bumper guard, reinforcing the idea that it helps safeguard the vehicle's front-end from harm and can lessen the impact of a collision. In some regions, you may hear it called a roo bar or kangaroo bar to reflect the increased chance of hitting wildlife in those areas. Regardless of the name, the primary function of a bull bar is to provide an added layer of protection for the car if an accidental situation arises.
