Driver Rules

Interstate Racway is a Division 5 NHRA track and follows all NHRA safety requirements. Below is a general overview, but please read the current rulebook as well.

2. Motorcycles 6.98 and quicker must be equipped with a FUNCTIONAL ignition kill switch that is attached to the rider by a lanyard(a tether). Most stock motorcycles are equipped with a handlebar mounted thumb switch that can have a lanyard easily attached for this purpose.

3. ALL motorcycles must have a chainguard.

Junior Dragster

There are several classes for children to race in purpose-built dragsters. All Junior Dragster classes run to the 1/8th mile. Any Junior Dragster that runs a 7.50 second or quicker ET or goes faster than 85 mph at any time will be immediately disqualified from the event. For license application information and the full Junior Dragster rulebook, see the NHRA website.

Gambler

Depending on the racing schedule and car count, we may call for a bonus race class called the Gambler. Gambler participation is open to any vehicles that have been eliminated from Bracket competition. This means that competitors from across classes can meet on the starting line and take a gamble against each other!

• Participants can receive a bye for one driver in the last two elimination rounds before Finals if there’s an odd-number of entries.
• Bye is decided by random number drawing and you cannot be awarded a bye twice.

Test and Tune

You’re welcome to bring almost any truck or car to run test passes at our track in a non-competition group called Test and Tune. A cage is required for anything faster than 6.33 seconds and you must pass a standard safety tech inspection (no leaks, no expired helmet, etc).
