A roll cage is a safety feature installed on vehicles used in high-risk environments, such as racing, military, and law enforcement. It protects occupants by preventing intrusion into the passenger compartment, but may not offer enough protection in serious accidents. Roll cages can be integrated into the vehicle structure or installed as a modification, and roll cage kits are available for many vehicles. Roll bars are also a common feature for additional protection.
A roll cage is a safety feature installed on a vehicle used in environments where there is a high danger of rolling, such as race car driving, as well as military and law enforcement use. Some cars are specifically designed with this feature installed, while others have had this device installed during an update.
The idea behind a roll cage is that if the vehicle rolls, it will protect the occupants. While some parts of the vehicle can be damaged or crushed, the cage prevents intrusion into the passenger compartment, creating a secure pocket. However, in serious accidents, it may not offer enough protection, and serious injuries are still possible, even if the roll cage works exactly as expected. This safety feature is designed to work with other safety features such as crumple zones and seat belts to provide protection in the event of an accident.
In race cars, rolling is a very serious hazard, because the vehicles travel at such high speeds that a roll could crush the vehicle. Similarly, vehicles used in police and military work often have high demands, making a roll cage a good safety consideration. Some luxury cars also have roll cages for safety reasons; In the case of convertibles, a system of bars and supports can be designed to be raised in an accident to protect the occupants of the vehicle if the vehicle rolls over while the top is down.
In vehicles designed to have a roll cage, the roll cage is integrated directly into the vehicle structure. In modifications, the cage can be installed inside or outside the car, depending on the design. It is important to have it installed by an automotive professional to confirm that it is installed correctly, as improper installations can be dangerous. Roll cage kits are available for many commonly roll cage-equipped vehicles, saving mechanics the need to fabricate custom parts for the purpose of an upgrade.
In addition to a cage, it is also possible to see a roll bar, positioned behind the driver’s head to offer protection. This feature is not to be confused with an anti-roll or sway bar which is used to stabilize a vehicle and prevent it from rolling. Stabilizer bars are also common features on vehicles used at high speeds.
