[1] The National Hot Rod Association in the USA began sanctioning the class in 1991, with the JDRL (Junior Drag Racing League).
The track is 1/8 of a mile, and depending on class, is contested as a bracket race or a heads-up start on a 5-tenths sportsman tree.
Drivers age 5-7 must use a crate engine from Briggs & Stratton with a slide valve to reduce power.
The different series restrict engine combinations and weight packages so that the cars do not exceed the 4.10 time NHRA says is the fastest junior dragsters can run to the 330 ft. legally.
Racers compete almost every weekend, running in points series at their home tracks, or in various specialty events with big prizes.
