The roll bar is a fundamental safety component in motorsports, primarily designed to protect the driver's head and torso during a rollover accident. Early examples were simple, single-hoop designs, but modern roll bars can be more complex, incorporating multiple bends and attachment points for increased strength and safety.
Roll bars are typically constructed from high-strength steel tubing, and their installation often involves welding them to the vehicle's chassis. They are a common requirement for track days and racing events, acting as a minimum safety standard. Roll cages build upon the roll bar concept to provide even more comprehensive protection.
