If a driver is involved in a major crash or roll-over, the driver may exit the vehicle if it is safe to do so. The driver is responsible for determining if and when he/she should exit the vehicle. Once clear of the vehicle the driver will wait in a safe area away from the track surface and impact zones until the Emergency Response Team arrives. A driver that has exited the car may walk back to the paddock by a safe route away from the racing surface and impact areas. Also see CCR section #25.7.
