  2. In case of accident, car must be taken into pits or infield (at a safe distance) to be worked on, subject to official’s decision.

Competing cars and drivers found in violation of rules will lose any purse money & points won for that night.

  1. Insurance coverage exists beginning 30 minutes prior to scheduled race time and ending 10 minutes after the finish of the last event.
  2. WEATHER POLICY: In the chance of sudden showers, the track starter will suspend the races; however, every effort will be made to complete the races after the rain stops.  If, in the opinion of Speedway Officials, the bad weather will prevent the return of a safe racing condition in a reasonable amount of time, the remaining races will be cancelled or postponed as follows:
  3. The program will be considered complete (no rain checks) if 4 or more events, not including time trials, have been run.
  4. If a special event was rained out, the special event may be added to the next weeks race show.
  5. In the event of rain, or any circumstances beyond the control of the Speedway Officials, the race may be declared complete or continued at the discretion of the officials in charge.
  6. If the program is not considered complete (see no. 1) your ticket stub or pit pass wristband will serve as a rain check for another race held within the next 2 race nights unless otherwise stated by Sycamore Speedway Management
  8. Green – Track is clear.
  9. Red – Indicates that all cars are to stop at once. The race has been halted.  Once cars have started to lineup for restart, latecomers will lose their positions.  Any car not ready for restart shall go to rear of pack.
  10. Yellow – Hold your position. Do not pass.  The lead car must slow down to parade lap speed, and ALL cars remain in single file at a constant slow speed all around the track.  Failure of the car to trail the car ahead will cause violator to lose position.  It is the responsibility of the lead car to slow down to parade lap speed.  When there is a yellow on the white flag lap, the race is over!  Cars will be scored on the finished lap previous to white flag.

NOTE: YELLOW FLAG LAPS NOT COUNTED*.  ANY CAR OR CARS INVOLVED IN A YELLOW FLAG SITUATION SHALL RESTART IN THE REAR.  ANY CAR CAUSING TWO YELLOW FLAGS IN ONE RACE MUST LEAVE THE RACETRACK FOR THE REMAINDER OF THAT RACE.  If you intentional cause a caution you will be black flagged for that race.  Any driver, pit crew member or family disturbing flagman or scorers before conclusion of racing program, will disqualify that car or be fined.  *At the discretion of the promoter, yellow flag laps may be counted.

  1. Black – The scorer will not count the laps of the black flagged car until he enters the pits and remedies the hazardous reason causing the car to receive the black flag. Failure to see the black flag will not be considered as an excuse.
  2. Blue w/Orange Stripe – Starters Signal – Hold your Line.
  3. Checkered – Race is over. When lead car gets checkered flag, race is over for all cars as they cross the finish line.
  4. The placement of the cars in order of finish as determined by the scorer will be final.
  5. The track steward reserves the right to increase or decrease the field of cars at his discretion.
  6. Any driver, who in the opinion of the track officials or flagman, shows evidence of exhaustion, drinking, under the influence of controlled substance or other physical incapacity, may be barred from the events in the interest of safety to himself and to others.
  7. Any person or persons willfully blocking the track or attempting to obstruct the race program will be requested not to return to the track for future race meets. Remember…when a rule is enforced, one or more people aren’t going to like it.

  11. Abandoned car will be towed away.
  12. When qualifying, an allowance of one spin or wave-off will be permitted per night. When time trials are over for a given class, they are over – no exceptions.  You will be allowed one qualifying lap or other means to facilitate positioning as time permits to be determined by the track officials.  Packing is required.  If you do not pack you do not qualify and therefore will be placed at the rear of the slowest heat and back of feature.  NO EXCEPTIONS.
  13. Wristbands appropriate for the event are required at all time. No Exceptions
  14. Only the tow vehicle will be allowed in the pits. No other car will be permitted.
  15. Any driver or crewmember deemed detrimental to the sport of auto racing will be refused entry to the pits. Auto racing is a competitive sport, but like any other event that lives from the support of fans there is, along with competition, a great deal of showmanship required.  STARTING ON TIME, running the events in a professional manner, PROPER UNIFORMS, race cars BRIGHTLY PAINTED and the CONDUCT of the competitors as viewed by the fans; these requirements form an important part of the contest rules and must be considered for the growth of auto racing.
  16. Abuse of any official and use of improper language at any time will be subject to disciplinary action. The penalty imposed will depend on the severity of the act.
  17. If in the combined opinion of the flagman, track officials and timer, a driver did not make the best effort to qualify, he will be positioned in the race lineup as judged appropriate.
  18. If for any reason a race stopped (such as red, yellow or checkered flag), only the persons allowed out on the track are officials, safety crew, wrecker and ambulance crew. NO ONE ELSE!  Anyone not conforming to this rule is subjecting themselves to a severe fine or expulsion from the grounds subject to discretion of track officials.
  19. Any driver, car owner, mechanic or any other person trying to organize others against the track or the officials in any way not limited to but including all forms of media, will be immediately suspended from Sycamore Speedway and barred from further competition.
  20. The following procedures must be observed in the pits:

      1. Any car missing an event because of this rule may start the next as an added starter; exception – those cars missing the consolation race cannot automatically start the feature as added starter.
    2. If you do not race your heat event, regardless of reason, you will forfeit your starting position for the feature.

    5. Any car that comes too late to qualify will be added to lineups as officials deem appropriate.
    6. To change drivers or cars, the driver going into the car must have qualified the car that night. This change must be reported to Pit Tower before race event.  As a driver you can only qualify one car per class and you must race that car all night.
    7. If your car breaks mid event, you cannot run someone else’s car with your number.
    8. Any fines and/or suspensions will be decreed by the officials, subject to the following: mechanical violations – maximum of $200 fine, safety violations – maximum of $500 fine and/or two weeks suspension.  Rain outs or race night cancellations do not count towards penalty.
    9. PROTEST RULE: If you feel one of your competitors is cheating, for $100 you can request that the car be inspected. $50 will be retained by the racetrack regardless of the outcome; the remaining $50 will go to the correct party.  If you claim a competitor is cheating and you are correct then you get your $50 back, if you are wrong the $50 will go to the competitor you wrongly accused.  The $100 you are paying is for a full tech, should this inspection result in an illegal car than the repercussions are the same as if the car was randomly picked for a full tech inspection, i.e. loss of points & money for the night.
    10. All cars must be removed from pit area after the conclusion of the evening events. ANY car left on the premises after ten days will be charged “storage”.  Pit lights out and pit area emptied and locked thirty minutes after race event.
    11. The track will reserve the right to reject any entry.
