All cars capable of attaining 150 miles per hour require braking parachutes. A safety requirement on all Drag cars running 9.99 and quicker in the 1/4 mile is the fireproof engine blanket which surrounds the engine block and contains debris in case of an engine explosion. NHRA rules call for a monetary, points, and time penalty if the car leaks oil during the run. During qualifying, the offending team loses its elapsed time and speed from the run; during a race, the penalty is loss of lane choice unless both teams in the ensuing race committed the violation.
