Roll bars are metal bars that reinforce a vehicle's frame and are designed to protect drivers in the event of a rollover. They benefit drivers by reducing rollover death rates, increasing performance during sharp turns, and providing great protection for both drivers and passengers. While often only associated with race cars, roll bars are actually beneficial for all vehicles by strengthening frames and improving anti-roll handling, as well as protecting occupants from side impacts and rollovers, which are often fatal without roof support. Aftermarket roll bars can be installed to provide these safety benefits.
