General Conduct

1.1Respect all officials, marshals, and fellow competitors. Aggressive, threatening, or unsportsmanlike behavior results in immediate disqualification and removal from the event.

Vehicle Tech Inspection

2.1All vehicles must pass tech inspection before competing. Tech inspection is final — no re-runs after a failed tech without correcting the issue.

2.3Helmets are mandatory for all drivers in convertibles, open-top vehicles, and any car running 11.99 or quicker.

2.5Loose items, unsecured interior panels, and aftermarket seats without proper mounting are grounds for tech failure.
2.6Any vehicle modified after tech inspection must re-tech before staging. Failure to do so results in disqualification.

Race Procedure

3.1Burnouts are permitted only in designated areas. Burnouts on the track surface outside the burn-out box result in disqualification from that run.
3.2Drivers must stage promptly when called. Failure to stage within 2 minutes of being called results in a forfeit.
