Roll cage
vehicle frame designed to protect occupants in the event of a crash / From Wikipedia, the free encyclopedia
A roll cage is a specially designed protective frame built in (or sometimes around) the passenger compartment of a vehicle.[1] Generally made of welded steel tubing, a roll cage is a safety feature in the event of a rollover or crash.[1] Roll cages are used mainly in auto racing and off-road sports such as rockcrawling. The roll cage also stiffens and adds strength to the vehicle which improves handling.[2] When the cage is constructed on the outside of a vehicle it is usually called an "exo-cage".[3]
