A roll cage is a protective framework installed in vehicles, particularly in racing cars, to enhance safety during accidents. It is designed to prevent the car's roof from collapsing and to protect the occupants by maintaining the integrity of the passenger compartment. Roll cages are typically made from strong materials like steel or aluminum and are engineered to absorb and distribute impact forces. In motorsports, such as NASCAR or Formula 1, roll cages are mandatory to ensure driver safety. They come in various designs, including full cages and half cages, depending on the level of protection required. Proper installation and adherence to safety standards are crucial for effectiveness.
