In the drag racing world, the NHRA and IHRA sanctioning bodies take safety to the next level by combining their resources with the SFI Foundation, examining elapsed times and speeds with car designs, and determining when safety items like battery cutoff switches, roll cages, protective clothing, and advanced driver licenses must be required. As speed increases, so does the required list of safety equipment, and both the NHRA and IHRA require a single parachute at 150 miles-per-hour speeds on the quarter-mile distance. Even though the eighth-mile standard is becoming more popular, having upgraded safety equipment is never a bad idea.
