Section 4 - FLAGS and SIGNALS

Riders are required to comply with all instruction given by a DRO Official or member of the safety crew, regardless if they are verbal instructions or transmitted to the rider by use of flags as listed in this section. Failure to comply constitutes conduct detrimental to the sport and the Race Director/Referee will levy penalties in accordance with Section 11 of this rulebook. Any penalties or fines levied as a result of violating the rule will not be subject to protest or appeal.

  1. Green Flag: Indicates start of race or clear track conditions. During a race or practice session, the absence of any flag(s) may be construed as a green flag.
  2. Crossed Green and White Flag: Halfway point in race.
  3. Yellow Flag
  4. Stationary - Be alert; be prepared to slow down; be prepared to change your line. There may be a condition ahead that is not normal but there is no immediate hazard. Passing and high speed are allowed, but exercise caution.
  5. Waving - Danger ahead. Slow down and maintain your line. No passing is allowed from the flag stations displaying the waving yellow flag until the rider is safely beyond the incident. Riders who violate this rule may be assessed a one lap penalty at the discretion of the referee. This penalty is not subject to protest.
  6. Blue Flag: A blue flag indicates you are about to be overtaken. If you are shown this flag, yield the racing line to the faster rider(s) that are approaching. It’s important to keep an eye out and be cautious as to not cause an accident.
  7. Black Flag: Unsafe equipment. The black flag is shown when a specific motorcycle presents a serious safety hazard (e.g. smoke, leaking fluids, dangling parts). If you are shown a black flag, get your motorcycle off of the racing surface as soon as you can safely do so. Do not complete your lap. Wait for instructions from a track official. Failure to properly respond to a Black Flag will result in immediate disqualification. Penalties levied as a result of this infraction are not subject to protest or appeal.
  8. White Flag: One lap remaining.
  9. Red Flag: Session or race has been stopped. There is immediate danger on the racetrack. All riders must signal (with hand or leg signals) that they are no longer racing, then reduce speed, safely complete their lap and return to the pits. No passing is allowed from the flag stations displaying the red flag to the track exit.
  10. Checkered Flag: End of session or race. Complete your lap and return to the pits.




  1. All participants must assess for themselves the facility, organization, safety measures, weather conditions, and any other considerations regarding the risk of competition at any given event. Participation indicates an assumption of all risks involved.
  2. The use of intoxicants or drugs of any nature which could affect the mental or physical abilities of any participant from his/her normal capabilities when in good mental and physical health are strictly prohibited. Failure to comply will result in punitive action up to or including a fine, one-year suspension, and removal from the track. All racers may be subject to drug testing. Failure to submit to testing procedures, or failure to pass the tests, will result in punitive action up to and including a fine and one-year suspension.
  3. Each rider is responsible for the behavior and action of any personnel, either family or crew, who is attached to his/her racing effort. Any punitive actions required for crew behavior will be levied against the rider.
  4. It is the responsibility of every competitor to notify race officials of any medical condition, which may be worsened by participation at that particular event. Permission to compete following such notification does not create an assumption of liability on the part of the officials or sanctioning body.
  5. All riders must sign an official entry form and release for each event, and no rider may practice or compete without such signature. Participation of any kind that results in an unregistered rider participating on the track in either a practice or a race event will result in punitive action against all parties involved including up to a $1000 fine and one-year suspension.
  6. Physical violence or abuse of any other person within the boundaries of the racetrack facility will result in immediate suspension, a fine, and possible prosecution through local law enforcement agencies.

Races are 6-8 laps.



Unlimited is 8 Laps

Middleweight is 6 Laps

6.2 RACE


  1. Three calls will be made prior to the start of each race. Each call will identify the upcoming race and either First, Second, or Third/Final Call. (These calls will also be used to announce practice sessions.)
  2. First Call – approximately 5 minutes until the start of the warm up lap.
  3. Second Call – Approximately 3 minutes until the start of the warm up lap.
  4. Third/Final Call – Approximately 1 minutes until the start of the warm up lap.
  5. One minute after Third/Final call is announced, the Pit Out will signal riders in the staging area onto the track for a warm-up lap. If a rider does not report to the staging area in within one minute after Third/Final call, the rider must report directly to the Track Marshall. The Track Marshall may allow the late rider to enter the track after all bikes have completed the warm up lap and commenced gridding. The late rider may enter the track and be gridded normally, but WILL NOT be allowed a warm-up lap.
  6. If a rider fails to make the start of their race, they may report to the Track Marshall and be allowed to participate and start from Pit exit. The Track Marshall may allow the late rider to enter the race in progress, but the rider will be docked the number of laps they missed in the final results.
  7. Riders must check grid positions at the track entrance. Riders who fail to verify their starting position before the Track Marshall signals the riders to enter the track may be required to wait until the field has gridded to enter the track.
  8. All motorcycles must come to a complete stop in their gridded positions before the starting procedures will begin. Riders who are not properly staged at the green flag will be assessed a stop and go penalty or a one lap penalty. A rider is considered staged if the front axle is behind, but no more than 18" behind, the designated row line and the front wheel is at a complete stop.
  9. Should an engine stall once the Race Starting Procedures have begun, the rider should wave to get the attention of the starter or a grid marshal. If possible, the rider will be given time to remove the motorcycle from the grid, and will then be given an opportunity to join the race once the field has left the grid.
  10. It is expressly prohibited for any rider to take a warm up lap for any race in which he/she is not an entrant.
  11. A jump-start is when a motorcycle’s front tire breaks the plane of the designated row line before the starter has signaled for the race to begin. Riders who are determined to have committed a jump-start will be assessed a stop and go or one lap penalty.
  12. If a rider jumps the start-before the starter has given the “go” signal, and the starter can halt the start procedure, the offender shall be moved to the back of the grid and the start sequence restarted.


  1. When a race is stopped (red flagged) it will be re-started using the original grid positions. All laps will be run after the re-start.
  2. A race lap is considered completed when the leader has crossed the start/finish line.
  3. A race is considered 50% complete when the leader has completed at least 50% of the race distance in whole laps. 50% of a race with an odd number of laps will be calculated by rounding up to the next whole number. (I.E. 50% of 15 laps is 7.5. Round up to 8).
  4. In the event that time constraints require shortening race distances no race will be called unless 4 continuous racing laps have been completed.
  5. Any race stopped with three or more of the laps completed, but before 50% of the race complete, will be re-started to complete the balance of the race distance.
  6. When more than 80% of the scheduled distance has been completed and the race is stopped, DRO officials may choose to call the race. If called, riders will be scored according to the positions held in the last completed lap that preceded the red flag.
  7. At the discretion of track officials, a rider or riders involved in an incident leading to or causing the red flag to be displayed may be scored as the last rider or riders to have completed the last lap scored for the purpose of determining finishing order. Also at the discretion of track officials, the rider(s) causing the red flag may not be allowed to compete in a re-started race.
  8. Any rider who is about to be lapped and appears to be deliberately blocking the lapping bike may be shown the black flag.
  9. A rider entered in a class may join the race after the race has started after being signaled onto the track by the Track Marshall.
  10. A rider may not rejoin the race on a different motorcycle if he/she has been on the racetrack during that race at any time after the green flag or green light was first displayed.
  11. If a motorcycle is unable to start a main event for which it qualified in a heat race, the rider may start the main event on a replacement motorcycle provided the replacement motorcycle meets the same class requirements as the qualifying motorcycle. In this situation, the rider must notify DRO Officials.
  12. If, for any reason, a rider is forced to stop on the track during a race, the rider is obligated to place the motorcycle on the track in such a manner as to cause NO danger or obstruction to other riders.
  13. Motorcycles may not be pushed while on the track except to remove them from a hazardous position to one of greater safety.
  14. If a motorcycle falls and its handlebar touch the pavement or ground it may not re-enter the track until the race is completed and permission to proceed back to the pits is given by a corner marshal or other track official.
  15. The motorcycle and rider's safety apparel must be re-inspected prior to competing in any further events.
  16. Any rider who crashes must be cleared by on site EMS personnel to be allowed to continue participation in the day’s events.
  17. Grid Positions – For each track, “Pole Position” will be placed on the most inside position on the front row.

6.3 Race Completion

A race consists of one or more classes running in a single competition. For purposes of scoring, classes running in a race are treated separately. However, for purposes of determining the end of the race, eligibility to complete a race, and designation as “Did Not Finish” (DNF) all motorcycles in a race, regardless of class, are considered as a single group and subject to the following:

  1. The race ends when the checkered flag is displayed to the lead motorcycle. This occurs:
  2. In a fixed lap event, when the lead motorcycle has completed the designated number of laps.
  3. In a timed event, the first time the lead motorcycle crosses the start/finish line after the designated amount of time has elapsed.
  4. When the checkered flag is displayed to the lead motorcycle, all motorcycles on the course and under power are allowed to complete their current lap and take the checkered flag. This final lap will be counted towards determining finishing position and number of laps completed. Motorcycles completing this final lap and taking the checkered flag are considered to have finished the race, regardless of the number of laps actually completed.
  5. When the checkered flag is displayed to the lead motorcycle, all motorcycles not on the course and/or not under power will be scored as DNF (Did Not Finish). Once the checkered flag is displayed to the lead motorcycle, motorcycles not on the course may not re-enter the course; further, motorcycles on the course but not under power may not re-start for the purpose of completing the final lap.
  6. A motorcycle is considered not “under power” when one or both of the rider’s feet are placed on the ground for the purpose of supporting or moving the motorcycle. 6.3.2 Finish Position
  7. For motorcycles under power at the end of a race, the finish position is determined by the total number of laps completed by each motorcycle. For motorcycles completing the same number of laps, the finish position is determined by the order in which the motorcycles crossed the start/finish line on their final lap.
  8. Motorcycles that Did Not Finish (DNF) will be positioned behind all motorcycles that did finish, regardless of the number of laps completed. Among motorcycles scored as DNF, the finish position is determined by the total number of laps completed by each motorcycle. For DNF motorcycles completing the same number of laps, the finish position is determined by the order in which the motorcycles crossed the start/finish line on their last complete lap.

6.4 Point Award Schedule

Points will be awarded according to the following schedule:


Pos: Points (Experts ONLY):

1st – 20 Points

2nd – 15 Points

3rd – 10 points

Riders who Did Not Start (DNS) will not be awarded points.


6.5 Points Classes

  1. Unlimited Expert points will accrue towards DRO top nine number plates for the following season. Points accrued in Unlimited is the ONLY way to earn to display a Top Nine numbers.
  2. All Other Classes will count towards the respective class championship.
  3. In the event that there is a tie for a championship, that tie will be broken based on the number of first place finishes in the class. If the tie is still not broken then 2nd place finishes, then 3rd place finishes etc. until the tie is broken.




  1. Riders must wear helmets on track surface at all times!

(As defined by 5.1.B)

  1. The responsibility for the decision to pass another rider rests with the overtaking rider, as does the obligation to do so safely.
  2. Any rider who appears to be deliberately blocking another motorcycle attempting to pass, or is observed to be riding dangerously will be penalized or disqualified. This is a judgment call by DRO officials and is not subject to protest.
  3. Should a rider leave the course, he/she must re-enter at the next safe location with no attempt to shorten the course or gain any advantage.
  4. If a motorcycle falls and its handlebar touches the pavement or ground it may not re-enter the track until the race is completed and permission to proceed back to the pits is given by a corner marshal or other track official.
  5. Upon completion of the event in which the fall occurred the motorcycle and rider's safety apparel must be re-inspected by a Tech inspector prior to continuing or competing in any further events.
  6. Any rider who crashes must be cleared by on site EMS personnel to be allowed to continue participation in the day’s events.

*** NOTE ***


Do not over twist your safety wire! The standard is 8 - 12 twists per inch for .032 diameter safety wire. Any more than that weakens the wire and could cause it to break under stress. Safety wire should always be installed so that tension is in the tightening direction. Proper safety wire installation is critical and one of the most important safety preparations for a race bike. If you are unsure how to properly safety wire your motorcycle, get help from an experienced racer or ask Tech Inspection.



   Section 10 – PROTESTS

10.1 The basic types of protests are:

  1. Scoring and/or Race Operations.
  2. Class suitability - visual discrepancies
  3. Class suitability - internal discrepancies

10.2 Inspection Covenants

By entering an event, each rider agrees to make each motorcycle on which he or she starts or joins a race available for inspection by the DRO Technical Inspection staff, whether the inspection is initiated by another rider entered in the class, or initiated by DRO officials. The rider agrees to keep his or her motorcycle available for protests or re-inspection for 45 minutes after leaving the racetrack in each class entered, and if such protest or re-inspection is ordered, for whatever time is necessary to complete the appropriate inspections. The rider further agrees to immediately make his/her motorcycle available for and to submit to inspection procedures involving disassembly of the motorcycle and collection of samples of fluids, materials, and parts at the event when requested by DRO officials or designated officials.

The rider has the right to be present, together with one additional person of his or her choosing, and to perform disassembly in the presence of and as requested by DRO officials, as well as to require that the DRO perform the disassembly.

The DRO has the right to retain samples of fluids, materials and parts for up to 60 days. The rider assumes all responsibility for conserving items disassembled, for all damages occurring during disassembly, and for appropriate re-assembly. With the consent of the rider, DRO officials may impound the motorcycle for later inspection at a mutually agreed on time and place.

Failure to comply with these covenants may result in fines, suspensions, and forfeiture of all class points for the season, as well as the upholding of the protest(s) received. DRO officials may assess more severe penalties for failure to comply with these covenants than would be assessed if a protest were upheld or the motorcycle were found to not be in compliance with the applicable rules, standards and/or limits.
