A roll cage is a protective framework built into a vehicle, particularly in race cars or off-road vehicles, to protect the driver and passengers in case of a rollover or crash. It is typically made of strong metal bars and is designed to prevent the roof or body of the vehicle from collapsing during an accident. The roll cage provides added safety by distributing the impact forces across the structure, helping to keep the occupants safe even in extreme conditions. It is a critical feature for vehicles involved in high-speed or high-risk driving.
