3 INTRODUCTION, NHRA JR. STREET (Page xv) (2/12/015) Pop culture observers who think young people s interest in cars is waning seem to have difficulty explaining a growing interest in motorsports among America s youth. In fact, to help meet the demand for teenagers wanting to drive fast, NHRA offers a racing program for year-olds that combines racing and car safety. NHRA Jr. Street gives teenage boys and girls the opportunity to race against their peers with an approved licensed supervising adult as a teammate. Competitors will go through an orientation/licensing procedure on an eighth-mile dragstrip in their vehicles, which must meet program requirements. Approved vehicles must be registered, insured, street-legal vehicles with mufflers and street tires and run 10 9 seconds and slower. NHRA Jr. Street is for drivers of full-bodied cars, trucks, vans, or SUVs. Prohibited vehicles include open-top SUVs or open-top SUV-type vehicles. Convertible tops are allowed but must be closed at all times. Motorcycles and race cars are prohibited. All vehicles must be street-legal and driven in and carry proof of vehicle registration and valid insurance. Vehicles also must display valid license plates and be able to pass all state highway safety requirements for the state in which the vehicle is registered. Participants may not compete in any other class except Jr. Dragster. As part of the membership purchase necessary for this program, participants also receive the digital edition of award winning National Dragster magazine, access to NationalDragster.net, and excess medical insurance (coverage may be different outside the United States). All of NHRA s member tracks are eligible to conduct NHRA Jr. Street activities. Those interested in competing should contact a member track by using the Member Track Locator at NHRA.com.
