A bull bar (also roo bar in Australia) is a device fitted to the front of a vehicle to protect the vehicle (and its passengers) from damage in a collision with an animal. They vary considerably in size and form but are usually made out of welded steel or aluminium tubing and more recently polycarbonate materials.

In Australia the term roo bar refers to a generally lighter weight bull bar, more suited for sedan vehicles, although both terms are somewhat interchangeable. In northern areas where cattle are more prominent and where larger four wheel drive vehicles are used, larger bull bars may predominate.
The bull in the name refers to cattle which in rural areas can roam onto roads and highways, although other animals such as sheep and horses also pose hazards. In Australia, kangaroos are the primary hazard in many areas, hence the name roo bar.

Traditional bull bars have limited use as a safety feature since they are built to lessen the damage to the vehicle, which contradicts modern safety thinking where controlled deformation of the vehicle is considered to be the most effective way of absorption of the kinetic energy that comes from movement. Because of this some countries have made bull bars illegal on vehicles that weigh less than several tons. From 2006 the use of bull bars on 4x4s and SUVs will be illegal in the EU.

Modern design of bull bars and roo bars however has advanced so that some vehicle manufacturers now offer impact bars which integrate with the vehicle safety system such as activation of airbags after collision with the bull bar. In recent times they have become popular also as a cosmetic accessory, particularly on 4x4s and SUVs. An airbag is a flexible membrane or envelope, inflatable to contain air or some other gas. ...

 A diagram demonstrating the guidelines for the design of "roo bars" in Australia. Kangaroos account for over 60% of animal collisions in Australia with the next most common victim being dogs at 12%. The relatively high incidence of animal collisions means that roo bars are commonly fitted to vehicles in Australia in outback or rural areas.

It was estimated by the Federal Office of Road Safety (FORS) (now the Australian Transport Safety Bureau (ATSB)) that roo bars or bull bars are involved in between 12% and 20% of accidents involving pedestrians in Australia. Over recent years there has been debate in Australia regarding the safety implications of fitting a bull bar.
In some states it may be illegal to drive a vehicle fitted with a bull bar that does not comply with the Australian Standard. The standard was created to stop the use of bull bars which have protrusions that may cause injury to persons or animals in an accident. The standard states that:
"No vehicle shall be equipped with any object or fitting, not technically essential which protrudes from any part of the vehicle so that it is likely to increase the risk of bodily injury to any person." Despite this, many vehicles each year are illegally registered with bull bars that do not comply with the standard.
