a metal bar or structure installed in a vehicle to protect passengers in case of a rollover
A roll bar is a safety feature in vehicles, particularly in sports cars, off-road vehicles, and race cars. It is a metal bar or frame positioned behind the seats, designed to protect passengers in case the vehicle rolls over. The roll bar helps prevent the roof from collapsing, reducing the risk of injury by providing a protective barrier. It is especially important in vehicles that are likely to be driven at high speeds or in off-road conditions, where the chances of a rollover are higher.
