PROCEDURAL RULES

(printer-friendly Procedural Rules)
1. All cars must be signed in at the pit entrance to be placed in heat races. All cars will be assigned starting positions according to handicap. Any car arriving less than thirty (30) minutes before the scheduled starting time will automatically start at the rear of the heat regardless of handicap.

  1. Any car unable to make its assigned heat will be placed directly into the consolation race.
  2. All cars participating in an event will assemble in the staging area during the preceding event and enter the track at the signal of the race director. All cars will stop in their starting positions at the start-finish line. At the starter’s signal, the field will begin its pace lap. The turn two pit gate attendant will regulate entry to the track after the start of the pace lap.You must come to a complete stop at the turn two entrance and wait for the flagman’s instructions. Failure to obey will result in disqualification.

There will be NO COURTESY LAPS for pitting or flat tires. With this and the interest of safety you will be allowed to enter the track after the field has taken the green flag and fall in the back of the pack as they pass the turn two-pit gate. You will not be considered a lap down. The turn two flagman will determine if your car is able to enter and when it is too late to enter. This is the only time you may enter track under green flag conditions.

  1. Turn two is the ONLY entrance to the racetrack. ANY CAR DISOBEYING THE TURN TWO PIT GATE ATTENDANT’S STOP SIGNAL OR ENTERING THE TRACK FROM TURN ONE WILL BE IMMEDIATELY DISQUALIFIED.5.There will be no driving the wrong way on the racing surface unless instructed to do so by an official.

All original starts will be controlled by the driver of the pole car, who may accelerate only after passing the white line in turn four. If the outside pole man goes before the pole man, the green will be displayed, but the yellow will come out by the backstretch. (NOTE: When a yellow is displayed immediately after a start, maintain a reasonable tempo until cars can be safely brought under control. Resist the temptation to drastically reduce your speed–remember there are people racing behind you!) The outside pole driver jumping the start will be warned the first time and sent to the rear for the second offense.

ORIGINAL STARTS: All original starts will be double file. The field will receive the green flag at the white line in turn four. Do not start to pass until you pass the start/finish line. If you break from line, you will be set back two spots for each car you pass.

RESTARTS: Restart lineups will revert to the last completed lap. Restarts will be double file for initial start. All subsequent restarts may be single file. Single file restarts will require cars to be NOSE-TO-TAIL, in line. On all restarts racing begins at the drop of the green. Any car obtaining an advantage on a single-file restart by being out of line may be disqualified or sent to the rear of the field. Restart penalties will be assessed on the next restart lineup. If the race ends without another yellow, the penalties will be assessed on the final order of finish.

  1. A race may be stopped at the discretion of the race director or starter if they consider it dangerous or unsafe to continue.
  2. The feature race shall run the full distance, if possible to run.

  4. Once an event has received a green flag, no other cars may join the field or be substituted (with the exception of proc. Rule # 3).No driver changes permitted after an event has received a green flag. Driver changes between events are permitted, but will result in the following: a) second car driven will start last in the next event, and b) first car driven will be scratched and must be re-qualified for the feature. In all cases-drivers, not cars, will be handicapped using a 3-week point average with maximum points awarded for races missed.
  5. DECISIONS OF TRACK OFFICIALS REGARDING RACE PROCEDURES OR SCORING SHALL BE CONSIDERED FINAL.
  6. When a race is halted for any reason, drivers must remain in their cars in order to restart the event as quickly as possible, Any driver leaving or working on a car on the racetrack will be sent to the rear. Any crewmembers leaving the pit area and entering the racing surface during an event will cause that car’s immediate disqualification from the event.

Lapped cars two or more laps behind the leader who impede or interfere with cars racing on the lead lap may be black flagged and removed from the event at the discretion of the starter.

Lap cars will move to the inside lane and stay out of the way of passing cars. If a lap car fails to listen to move over flag or gets passed on the inside, they will be black flagged out of race. They will receive last place points and money for the amount of cars that were on the track at the time of the black flag.

FLAG RULES

GREEN FLAG: The track is clear for racing–the event has officially started (or restarted). If held in a rolled position, you will be going green the next time around.

YELLOW FLAG: The most important flag, simply means SLOW DOWN, stay in line, no passing, and keep your eyes open for an accident, stalled car, debris, or anything else dangerous to you, fellow competitors, or spectators. You must get into single file for safety and line up purposes until told by officials to double up if so needed. Anyone not abiding by this rule will be sent to the back for the next re-start.

There are corner men, traffic lights, plus the starter who will be showing a yellow flag or light to warn you of impending danger. Anyone racing under the yellow will receive the following penalty:

1ST TIME: Verbal warning by the starter.

2ND TIME: Disqualified from the event and the rest of the night.

3RD TIME: Disqualified from the event, the rest of the night, and a week suspension and possible fine from raceway management.

RED FLAG: Simply means stop as quickly and safely as possible, there has been a bad crash and possible driver injury. All corner men have red flags and there are three traffic lights to warn you of a red flag condition. CARS ENTERING THE PITS UNDER RED FLAG CONDITIONS WILL BE DISQUALIFIED FROM THE EVENT. Under the red flag the only movement permitted will be at the direction of track officials. Move only to the extent of their direction as safety vehicles may be operating on the raceway. When the emergency situation is cleared, cars will be signaled to move by yellow flag or yellow traffic lights. At this time, proceed with caution to the start/finish line for realignment or to the pits for repairs. Failure to stop within a reasonable distance or movement under the red will result in the following penalties:

1ST TIME: Verbal warning by track official (those entering the pits will be disqualified from the event).

2ND TIME: Disqualified from the event and the rest of the night.

3RD TIME: Disqualified from the event, the rest of the night, and a week suspension and possible fine from raceway management.

1ST TIME: Verbal warning by starter (NOTE: Since it is impossible for the starter to give you a verbal warning while the race is going on, if you are totally disobeying the passing flag, you will be black flagged at his discretion–see black flag).

2ND TIME: Black flagged, disqualified from the event.

3RD TIME: Disqualified from the event, the rest of the night, and a week suspension and possible fine from raceway management.

BLACK FLAG: You have been disqualified from the event for a rule infraction, or a safety hazard exists (smoking, leaking, mechanical problem, etc.) with your racecar. PULL INTO THE INFIELD IMMEDIATELY. You will receive the black flag two (2) times along with the chalkboard with your car number on it. If you do not pull off after two laps, you will no longer be scored or a yellow may be brought out to remove you from the event. If a yellow is required, you are disqualified for the night, for a first offense.

2ND TIME: Disqualified for the night and a week suspension and possible fine from raceway management.

3RD TIME: Same as above with a two-week suspension.

WHITE FLAG: One lap to go in the event.
