   4. If a car is allowed to make a change due to a pending mechanical issue, they will be forced to start at the rear of the field for the feature event.  SCSCS officials have the final say in allowing work to be done on a car following qualifying.
   5. The field will be ranked from the fastest to the slowest qualifier.  If two cars run identical times, the car that ran the time first will receive the higher qualifying position.
   6. After qualifying, the top six qualifiers will report to tech to draw for their starting positions 1-6. 
   7. If qualifying is not available or is rained out, the field will start by points with the current point’s leader being listed as the pole winner.  The field will then be inverted by five cars. 
   8. Unless otherwise posted, the normal starting field will be 28 cars on time and two provisional starting spots. 
   9. Competitors will be eligible for one of two provisionals for each event.  The provisional starting positions will be granted to the remaining two cars not qualified for the event on time that are highest in the current point’s standings.  If all eligible cars have qualified for the race, the provisional will be awarded to the fastest remaining cars. 
   10. A Promoter’s provisional is available at the discretion of the Director of Competition.  A competitor cannot receive more than one Promoter’s provisional during the year.
   11. If a car is not able to make a qualifying attempt, but is entered and present at the race, that car will receive last place points based on the number of cars starting the race.  In the event that all 31 spots are occupied by qualified cars, the non-qualifier will receive 40 points.

   4. A qualified car may be driven in any event by an eligible SCSCS driver.  However, if a driver change is made during the event, the driver starting the event will receive all points and posted awards.  The driver qualifying the car must start the race.
   5. Cars will start the race in a double file format.
   6. If there is a caution before the first lap is completed, the cars involved in the caution will relinquish their position and restart at the rear of the field.  The outside and inside lines will advance as necessary and the field will again restart double file.
   7. All races will be 100 laps unless told otherwise.
   8. The flagman will start the race, NOT the competitors.
   9. If a caution flag is displayed, all cars must slow down to a safe and cautious speed immediately.  The cars will proceed in a single file format behind the pace car in the position they were running on the track at the last completed green flag lap.   Lap cars will hold their position in the field until the one to go signal.
   10. The restart position of each car will revert back to the last completed green flag lap.
   11. Caution laps will not count.  Only green flag laps will count. 
   12. If there is a discrepancy between competitors regarding a position, they are to cautiously proceed side by side under caution until notified by the flagman or race control of their position.
   13. All cars involved in the caution regardless of fault will relinquish their position and go to the tail of the field. 
   14. In the event that a car spins another car and causes a caution, the car that was spun will go to the rear of the field.   If the car causing the spin was deemed intentional and with malice, that car will start at the rear of the field, not the rear of the lead lap cars.  All other cars involved that are on the lead lap will line up at the tail end of the lead lap cars, or tail of the field if they are one or more laps down.
   15. If cars choose to pit during a caution they will relinquish their current position and return to the field at the rear.  If they are on the lead lap, they will be allowed to advance to the last car on the lead lap.  If they are 1 or more laps down, they will go to the rear of the field.
   16. The field will be given the one to go sign and will go back to green flag racing on the next lap.  When the one to go sign is displayed, all lap cars will pull to the inside and allow the lead lap cars to advance.  The lap cars will line up behind the lead lap cars in the position they were running on the track, not by their position in the race.  Lap cars have the option of starting at the tail end of the field on a restart if they desire.  If they let one car by, they must let all cars by.
   17. All subsequent restarts will take place at the designated restart area of the track and will be controlled by the current race leader.  The leader may not start the race until they are in the designated restart area.  If the leader passes through the restart area and does not start, the flagman will restart the race.  Penalty for jumping the start will be a black flag and a stop and go penalty.
   18. No cars are allowed to pass to the left before crossing the start finish line.  Failure to comply will result in a stop and go penalty.
   19. A Blue flag with a line indicates that slower cars are being overtaken by the leaders.  If this flag is displayed to you, you are allowed to race the leaders as normal until you are a lap down.  After you are a lap down, you must adhere to the flag and move to the bottom of the track and allow the leaders to pass.  Failure to abide by this flag will result in a black flag for a stop and go penalty.
   20. The black flag means go to the pits immediately and report to an official.  Once the penalty or mechanical issue is fixed you are eligible to return to competition. 
   21. If a red flag is displayed, all competitors will stop on the race track as designated by SCSCS officials. 
   22. SCSCS races will not end under caution.  The race is not over until the leader receives the checkered flag.
   23. If a caution is displayed within the last three laps of a race, the field will restart single file with three laps to go.  The laps will be Green, Green, White, and then Checkered.  This format will continue until the race finishes under a green flag scenario.
   24. The race is over when the leader takes the checkered flag.  All other cars will finish the race in the same lap.
   25. The top three finishers will be directed to the designated area or starting line for interviews.  They will remain with SCSCS officials for further inspection until released by SCSCS officials.
   26. Crew members may not go out on the racing surface during competition, caution, or a red flag condition.  If so, they will be disqualified from the event and may face additional fines from the series.
   27. If an event is delayed due to weather, accident, or other uncontrollable events and is not able to resume.  The race will be considered official if 50% or more of the race is complete.  If so, the finishing order will be based on the last completed green flag lap.
   28. Any driver who does not obey the flags or SCSCS officials will be disqualified from the event.
   29. Any driver intentionally causing an accident or yellow flag condition is subject to lap penalties, disqualification, and/or fines depending on the severity of the situation.

   2. If a car needs to pit during the race, they are allowed.  Pit road will be designated at each event.
   3. Cars must adhere to a safe pit road speed while on pit road.  This speed is not to exceed the pace car speed.
   4. No tire changes allowed unless a tire is flat as a result of competition.  If a tire is changed, the tire that was changed will be subject to inspection by a SCSCS official.  Any additional tires used during the race, must be a used tire.
   5. Cars that do pit will return to the race as soon as their work is completed.  If this is under a green flag situation, they are required to yield to the other competitors and re-enter the racing surface in a cautious and yielding way.  If the pit stop is under caution, they will return to the track behind the last car running on the track.  If they are on the lead lap, they will restart as the last car on the lead lap.  They are not allowed to blend into traffic. They may not advance the pace car at any time without consent of SCSCS officials.  Caution laps will not count and cars cannot be lapped in the pits except under a green flag situation.
   6. No fueling of the cars allowed during competition.
