The National Hot Rod Association (NHRA) establishes rules for every type of vehicle that can run down the quarter-mile. All NHRA member tracks must follow these safety guidelines. Each year, a new NHRA Rulebook is published with revisions and updates. Rulebooks are available at the track for $10, and are highly recommended for anyone who is interested in participating more frequently or building a car.

The basic items needed to pass tech inspection for the typical street car include good tires, a battery tie-down, radiator overflow catch-can, operable neutral-safety switch, seat belts, and a valid state driver's license or NHRA competition license is required for all participants. Don't forget to wear long pants, shoes, and a shirt!

A helmet is one of the first safety items that you may need to purchase. Any vehicle that runs faster than 13.99 seconds, and all motorcycles and dune buggy-type cars, must have an approved helmet. Helmets must have a SNELL rating of 2010, 2015 or 2020, as well as those with an SFI rating of 31.1A, 31.2A, 41.1A, or 41.2A. (SNELL 2010 helmets expire on 1/1/2022, SNELL 2015 helmets expire on 1/1/2027, SNELL 2020 helmets will expire on 1/1/2032).

NHRA allows the use of nitrous oxide in bracket classes. Check the track's specific class rules to be certain, but in most cases you can use nitrous. Nitrous bottles must be vented to outside the driver compartment if it is mounted in the same compartment as the driver. All bottles must be stamped with a DOT - 1800 pound rating.

The following is a list of major items that are required at specific ET's and speeds. This list is a guideline, and we recommend consulting a current NHRA rulebook for specific details, specifications, and diagrams.

A minor release form is available at Tech Inspection for children from ages 14-17 years. This release will allow them to be in a restricted access area. The restricted access area is defined to start at the back of the tower and extend through the track and return road to the ET Slip Booth. He or she is only permitted in this area while supporting a car making a run at that time. Upon completion of the run being supported they must depart the restricted access area. Anyone under the age of 14 or children without a Minor Release on file must remain seated INSIDE of a tow vehicle or not enter the restricted areas. No one under 16 years of age is allowed to operate any vehicles (including but not limited to tow vehicles, motorcycles or 4-wheelers) anywhere or ride in/on a vehicle making a run.
