Drag racing

Drag racing is a type of motor racing in which automobiles or motorcycles compete, usually two at a time, to be first to cross a set finish line. The race follows a short, straight course from a standing start over a measured distance, most commonly 1⁄4 mi (1,320 ft; 402 m), with a shorter, 1,000 ft (0.19 mi; 304.80 m) distance becoming increasingly popular, as it has become the standard for Top Fuel dragsters and Funny Cars, where some major bracket races and other sanctioning bodies have adopted it as the standard. The 1⁄8 mi (660 ft; 201 m) is also popular in some circles. Electronic timing and speed sensing systems have been used to record race results since the 1960s.

The history of automobiles and motorcycles being used for drag racing is nearly as long as the history of motorized vehicles themselves, and has taken the form of both illegal street racing and as a regulated motorsport.

History

Drag racing started in the 1940s. World War II veterans were prominently involved, and some early drag races were done at decommissioned aircraft bases with landing strips that made them an ideal place for the sport. In 1951, Wally Parks formed the National Hot Rod Association (NHRA). The organization banned the use of nitromethane in 1957, calling it unsafe, in part through the efforts of C. J. Hart; the ban would be lifted in 1963.

Several other racing organizations were created over the past several decades, such as the Professional Drag Racers Association (PDRA) founded in 2014.
