A roll cage is a protective framework installed in vehicles, particularly in racing cars and off-road vehicles. Its primary purpose is to provide structural support and protect occupants in the event of a rollover or collision. Made from strong materials like steel or aluminum, roll cages are designed to absorb and distribute impact forces, enhancing safety. In motorsports, such as NASCAR or rally racing, roll cages are mandatory to ensure driver safety. They are custom-fitted to each vehicle's design and must meet specific safety standards set by organizations like the Fédération Internationale de l'Automobile (FIA).
