International Hot Rod Association

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, with a shorter, 1,000 ft 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 is also popular in some circles. Electronic timing and speed sensing systems have been used to record race results since the 1960s.

The National Hot Rod Association (NHRA) is a governing body which sets rules in drag racing and hosts events all over the United States and Canada. With over 40,000 drivers in its rosters, the NHRA claims to be the largest motorsports sanctioning body in the world.

A dragstrip is a facility for conducting automobile and motorcycle acceleration events such as drag racing. Although a quarter mile is the best known measure for a drag track, many tracks are eighth mile (201 m) tracks, and the premiere classes will run 1,000 foot (304.8 m) races. The race is begun from a standing start which allows three factors to affect the outcome of the race: reaction time, power/weight ratio, and traction.

Pro stock is a class of drag racing featuring "factory hot rods". The class is often described as "all motor", due to the cars not using any form of forced induction such as turbocharging or supercharging, or other enhancements, like nitrous oxide, along with regulations governing the modifications allowed to the engines and the types of bodies used.

The Junior Dragster or Jr Dragster is a scaled-down version of the top fuel dragster. The cars were developed in New Zealand in 1988, with classes developed by the New Zealand Hot Rod Association. The National Hot Rod Association in the USA began sanctioning the class in 1991, with the JDRL. The JDRL is a division of the NHRA, which consists of two different dragster classes, traditional Jr. Dragster having a wheelbase between 90 and 150 inches and a single-cylinder, five brake horsepower Briggs & Stratton engine, and the larger Jr. Comp dragster being 150-190 inches in wheelbase and using a motorcycle or personal watercraft engine. Junior drag racers may choose to participate in programs run by the NHRA, IHRA and the Australian National Drag Racing Association [ANDRA], or at an unsanctioned facility. Drivers may be male or female and must be at least five years of age to test, and six years to compete, and be no older than 20 years on December 31 of the competition year.
