The Delaware Office of Highway Safety was established on July 19, 1968 by Executive Order 35. Although it is a state agency, the Office of Highway Safety and its activities are primarily funded through federal grants from the National Highway Traffic Safety Administration (NHTSA).
Dover International Speedway is a NASCAR-sanctioned 1 mile (1.6 km) race track located in Dover, Delaware, owned by, and serving as the corporate headquarters of, Dover Motorsports, Inc. It is co-located with a harness racing track, Dover Downs, and shares the complex with Dover Downs Hotel & Casino. At one time both the entertainment complex and the speedway were owned by the publicly traded Dover Downs Entertainment, but they have since been split into two separate companies. Among NASCAR enthusiasts, the track has earned the nickname of "The Monster Mile".
