F. RACE FORMAT

1. The race format will consist of two motos per class with a combined overall result.
2. There will be no more than 20/21 riders per gate drop (based on capacity of the start gate). Motos/qualifiers may be stagger-start.
3. In the event there are 21 or more riders in a class, the following program will be used:
   a. The top 4 riders will be divided into equal qualifier groups based on current point standings, with the higher ranked riders being assigned to different groups to avoid all top ranked riders competing in the same qualifying heat, i.e., 1^st and 2^nd place in points and 3^rd and 4^th place in points will be in separate groups. This does not necessarily mean that 1^st and 3^rd will always be in the same division or 2^nd and 4^th will always be in the same division. The number of divisions will depend upon the number of entries.
   b. All riders who do not advance from the qualifiers are eligible to compete in the last chance qualifier (LCQ) races.
   c. Rider advancement from qualifiers and LCQs are as follows:
   

   TOTAL ENTRIES	# OF DIVISIONS	ADVANCE TO MOTO 2	# OF LCQs	ADVANCE FROM LCQ TO MOTO 2
   20 entries or less	1	ALL	0	NA
   21 – 36 Entries	2	8	1	4
   37 – 40 Entries	2	8	2	2
   41 – 56 Entries	4	4	2	2
   57 – 76 Entries	4	4	3	2/1/1*
   *Fastest LCQ transfers two (2) riders; other two transfer one (1) rider each.

   d. Riders advancing from the qualifier motos will transfer their earned points according to their finishing position, i.e., a rider finishing in 1^st place will receive one (1) point, a 2^nd place finisher will receive two (2) points, etc... Riders transferring from the LCQ will transfer their earned points according to the next finishing position, i.e., if 8 riders transferred from each of the qualifier motos, the winner of the LCQ will receive a 9^th place position, and so on. In the event the 2^nd moto is cancelled, points will be awarded based on finishing position in qualifying motos, followed by the LCQ finishing positions, whereas event awards will be awarded based on 2^nd moto gate pics.

G. STAGING/START LINE PROCEDURES

1. Gate Pics:First moto gate pics for the Pro-Am class will be determined by one 15-minute timed qualifying session where the top 20 times will advance to Moto 1. For more than 20 riders, the top 16 will advance to Moto 1 with a 3-lap consolation race to determine the final 4. For all other classes, first moto or qualifier gate pics will be determined by computer draw. Second/final moto gate pics will be determined by first moto/qualifier finishing position, with the faster qualifier moto taking precedence.  At the final round of the series, first moto or qualifier gate pics will be determined by the current Top-10 point standings, and the remainder by computer draw (excepting the Pro-Am class).
2. The Staging Area and Start Line are “No Smoking” zones.
3. Once a machine enters the Staging Area and is called to the Starting Gate, the machine will not be permitted to return to the paddock. If the machine is removed from the Staging Area after this point, the rider will not be permitted to start the race, unless approved by the Race Director.
4. Riders should accompany their machines to the gate. Once a rider pulls into a gate slot, they may not move to another gate unless directed by an official.  Machines must be positioned straight and in the center of the gate.  Youth riders may straddle ruts so long as a minimum space of 6-inches remains between riders.  The back tires cannot rest on top the backstop.
5. Only the rider’s designated Mechanic may accompany the rider to the gate. No other persons are permitted on the Start Line.  Sponsors and family may only visit in Staging, but not on the Start Line.
6. No one is permitted in front of the Start Gate. Absolutely no maintenance can be done to the area in front of the Start Gate.
7. The area between the Start Gate and the backstop may be groomed with hands and feet only – tools may not be used. Mechanics may not use golf shoes or cleats in this area.  No dirt, water or other material may be added to the area between the Start Gate and the backstop.  However, excess water can be removed from this area with cups, buckets or brooms.
8. Riders must start each race with their tether cord properly affixed.
9. The Start Procedure is as follows:
   • 2-Card will be held for 10 seconds
   • 1-Card will be held for 10 seconds
   • 1-Card will be turned sideways
   • Gate will drop between 2 and 5 seconds
10. Mechanics must step behind the backstop at the display of the 1-Card.
11. Riders may request a 2-minute grace period for minor repairs at any time prior to or during display of the 2-Card. Once the 1-Card is displayed, no additional time will be given.   Only one grace period will be given per moto.  Grace periods will not be given to clean equipment or for cosmetic purposes.

H. RACE PROCEDURES

1. Pro, Pro Sport andWMX motos will be held Saturday; Pro-Am motos will be held Sunday. Site laps will be given for each Pro-Am moto.  For all other classes, 1^st moto/qualifiers will be held on Saturday and 2^nd moto/LCQs on Sunday.
2. To accommodate the 50cc classes, a shortened track may be used as necessary.
3. A rider leaving the course may continue the race by properly re-entering the course at the closest point to where the rider left the course, without gaining an advantage. If a rider leaves the course for any reason, the rider must immediately slow down to a safe speed so as not to endanger life or limb of other riders, crew members, officials, or the public.   It will be the responsibility of the Race Director or his designee to determine whether the rider gained an advantage upon re-entry or failed to slow down after leaving the course. A rider may be determined to have gained an advantage without gaining a position.
4. A machine that leaves the confines of the racecourse boundary during a moto race will not be permitted to return to the racetrack.
5. Outside assistance to a rider on the course is prohibited except when the assistance is given by flag marshals or race officials for the purpose of control and safety. Mechanics may assist riders hung up on the starting gate; otherwise, Mechanics must remain in the Mechanics Area and may not enter or cross the track for any purpose.  Once a race machine is hooked to a tow vehicle, it may not re-enter the competition for that moto.
6. Radios are permitted between pit crew members, but not with or between riders.
7. No rider may ride in such a manner as to endanger the life or limb of other riders, officials or the public. Riders will be penalized for the reckless operation of their machine or for running into an official.
8. Unsportsmanlike conduct or deliberate ramming, blocking, or intentional contact with another rider will result in a penalty.
9. Team tactics include blocking or allowing another rider to pass in order to affect the outcome of the race. Riders involved will be penalized.

I. RACE FINISHES

1. Transponder scoring is the official scoring process. The finish line will be marked and clearly visible.
2. Race Finish: The race officially ends for all contestants at the completion of the lap in which the checkered flag is displayed to the winner. Should the checkered flag be displayed later than the official distance, the finishing order will be decided on the basis of the official advertised distance. Should the flag be inadvertently displayed for a rider other than the race leader, the end of the race will revert back to the last completed lap of the race leader.
3. Finish Position: Riders will be scored in order of finish and laps completed. It is not necessary to complete all laps in order to be scored. Any rider who makes at least one lap will get a finish position for that moto.
   DNF: A rider who starts the race but does not make at least one lap will receive a “Did Not Finish” or DNF. A DNF results in moto points equal to the total number of riders in the class, but not less than twenty (20).
   DNS: A rider who does not report to staging will get a “Did Not Start/Stage”. A DNS results in moto points equal to the total number of riders in the class, plus thirty (30) points.
4. Results: A rider may question the results within the 30-minute period following posting of final results. After 30 minutes, awards will be given out and results will be final unless a protest is pending. Provided, however, that the issuance of official results does not exempt riders who competed in the event from penalties for rules violations issued by ATVMX Officials following the protest period.
5. Awards are given at the rate of (1) per (3) riders with a minimum of (5) awards per class based on event overall results.

J. NATIONAL NUMBERS
