For the safety of the driver and the other competitors on the track, any race car must be certified before racing. The SFI Foundation, founded in 1978, tests and certifies racing equipment offered by various manufacturers. SFI certifies tech inspectors that look over cars before they compete in racing events.
NASCAR, for example, requires that a vehicle have a certified roll bar, five-point harness, roll cage, window webbing and chassis. Specialized seats must be installed that include padded headrests. Tires must have a safety liner that minimizes the chances of an accident if a blow out occurs. Cars must also carry fire extinguishers in the cockpit. Drivers must wear certified helmets with full-face protection and fire-retardant uniforms.
