Races will start coming off of turn 4.  Anyone caught jumping the start (flagman's discretion), will be penalized two spots in the final scoring.  Restarts will be from the orange cone on the front straight-away.  You DO NOT PASS until you have passed the orange cone, STAY IN LINE!  DO NOT HIT OR GO UNDER THE ORANGE CONE, if you do, you will be disqualified.

The blue flag with a yellow diagonal stripe is the move over flag for lapped cars.  If you are being overtaken by the leaders you will be given this flag, we request that you maintain your racing line, but respect the racing line of the leaders as you are being passed.

If you stop on a yellow flag, or you cause the yellow flag, you will be started at the rear of the field on the restart. The two (2) spin rule is in effect.  If you spin out twice, causing a yellow flag, you will be flagged to go into the pits.  If you go into the pits DURING your event, you will NOT be allowed to re-enter the race track.

Cars may be worked on during a red flag condition, at the top of the 2nd corner ONLY!  If you change tires (ANY) during a red flag, YOU WILL RESTART AT THE REAR OF THE FIELD.

If there is an unusual amount of yellow flag laps without a red during the 30 lap A-Main, will will stop the race for refueling ONLY.  You will not be allowed to do anything else on the car.

Cars will be teched at a specific location within the pit area (impound area will be roped off).  The TOP 10 cars must go directly to the impound area (if you are in doubt, stop at the impound area). The TOP 5 cars of the A feature will be weighed and fuel sample drawn.  The top 5 cars will draw to see which one (or two) gets a COMPLETE inspection.  If one of the top 5 is DQ'd for any reason, the next place car will be teched for the 5th place, etc.  The roped off area will be limited to the Tech. Inspectors, Association Officials, and the Driver/Owner ONLY!  Weight is 725 lbs. minimum, without the driver (+/- 2 lb. buffer for scale accuracy).  Fuel is gasoline or alcohol only (NO oxygen enhancing fuels or fuel additives).  Displacement is 1205cc maximum.  Each will be informed as you come off of the track, as to which ones will GO DIRECTLY TO THE TECH AREA. DO NOT GO TO YOUR PIT AREA.  If you go on INTO or THROUGH the pit area you will be disqualified.  If you are not certain as to where you placed as you come off of the track, stay at the tech area.  If you are told to go to the tech area, and do not, you will be disqualified.

ROUGH DRIVING & FIGHTING WILL NOT BE TOLERATED AND WILL RESULT IN AUTOMATIC DISQUALIFICATION,  and you will not receive a refund. A professional attitude is a must. Arguing and cursing at the officials WILL NOT BE TOLERATED.  You will forfeit your winnings for the event.  The scorekeepers final tally is official.  Payoff will be held after the total tech inspection is completed at the black Rod End Supply trailer.  Your social security number WILL be required to receive any payoff.
