Starting and Staging

  1. Vehicles must be in the starting area when the class is up and must be ready to run or they will be disqualified.

No friends or helpers of any kind are allowed to help after the vehicle has entered this area. If you are unwilling or unable to race for any reason after crossing the staging line you will be disqualified.
  3. After the first vehicle has reached the 20 foot pre-stage line, the second vehicle has one minute to get there. After your competitor is staged you have 30 seconds to be stages. If you are not on time for either of the reasons stated above, you will be disqualified. A competitor may raise his hand if he sees unsafe track conditions.
  4. A competitor is considered staged when he has pulled up to the line, his staging light is on or he has nodded to the starter (in the case of a flag start). When a driver is staged, the vehicle will be stopped and the driver will be watching the starting light (or flagman). THERE WILL BE NO BLOCKING OF WHEELS.

  8. There shall be a minimum of 50 feet between edge of drag strip and spectators.
