2012 AMA Racing ATV Extreme Dirt Track National Championship Series
Supplemental Rules
All rules in the 2012 AMA Racing Rulebook will govern these events unless set forth in these supplemental rules.
Red Text - 2012 Changes
RIDER ELIGIBILITY 
All current ATVA Competition members or AMA full members, in good standing and who meet the necessary age requirements, on or before the date of the event for the classes they are entering. Riders that change age during the season may stay in the class they started the year in, or may advance, not both. Points accumulated to that point do not advance with the rider to the new class.
PRO CLASSIFICATION
Pro riders are eligible to compete in Pro, Pro-Am and Pro-Am Unlimited classes. In non-national competition, Pro Riders must enter in the highest classes available. Pro riders wanting to return to the "A" class in National competition must wait one calendar year. During that year they are allowed to compete in Pro-Am and Pro-Am Unlimited classes only. See Rider Advancement below.
PRO-PROVISIONAL
At a meet where there are less than 20 Pro riders, a Pro-Provisional will be allowed at the discretion of the referee. A Pro-Provisional will allow
Pro-Am and Pro-Am Unlimited racers to try and qualify for the open positions in the Pro Race. A qualifying fee of $25.00 must be paid per rider.
Pro-Provisional qualifying will take place Friday night. The referee or board members will have the final determination of which qualifiers will fill the remaining Pro Race open positions until the Pro field is at 20 riders. The qualified racers must then pay their entry fee into the Pro Class ($100.00). The Pro-Provisional qualified racer is no longer eligible for any amateur class for the rest of the season. The Pro-Provisional is for the current event only, and rider must return to the Pro-Am and/or Pro-Am Unlimited class at the next event. If the Pro-Provisional is used, Pro Heat lineup will be by season points for the Pros (no Pro Qualifying Friday night) and the qualifying times for the Pro-Provisional racers.
PRO-AM & PRO -AM UNLIMITED
Pro, “A”, 16-24, 25+ Veteran and Senior class riders may compete in the Pro-Am or Pro-Am Unlimited classes. Pro-Am and Pro-Am Unlimited riders may not compete in any “B” or “C” classes. See Rider Advancement below.
RIDER CLASSIFICATION
Riders shall be classified the same as local AMA/ATVA District participation. Riders who participate in a higher level of classification at any local AMA event will be considered as advanced to that higher classification. Any non-AMA event will not be recognized by the Extreme Dirt Track Series.
RIDER ADVANCEMENT
If a Pro, Pro-Am, Pro-Am Unlimited, Amateur or youth rider feels they should be advanced sooner to a higher classification, the rider must submit a written request to the AMA Track Racing Manager and provide justification to be advanced.
Pro: To be eligible to race in the Pro class, a rider must have finished in the top 33%, (excluding Pro riders that raced in Pro-Am or Pro-Am Unlimited class) in a minimum of three Pro-Am or Pro-Am Unlimited meets at an AMA Racing ATV Extreme Dirt Track National, within the last 12-month period.
Amateur: A rider must compete one season as an amateur to be eligible to compete in Pro-Am classes or have approval from the AMA Track Racing Manager or EDT Referee.
Youth: The highest class youth riders may advance in a single season is to amateur A.
“B” & “C” Class Riders (important note)

Referee may permit use of a shortened or separate track as necessary. Knobby tires allowed.
2. Machines may be used in multiple classes by the same rider provided that both rider and ATV meet the requirements of the class.
3. All machines must be class legal each time they pull up to the starting line or be subject to disqualification. A rider may change machines between races as long as the replacement is class legal. Starting position will be 24' behind the last occupied line or the penalty line. Once a race is started, there can be no changing of machines.
START OF RACE will be defined as FIRST ATTEMPTED START, even if it results in a complete restart. If you switch bikes (before the start of the main event) it has to be approved by the Referee or the rider will be subject to disqualification.
4. Production Classes: Stock frame and ATV engine cases from the original manufacturer of that make and model must be used. OEM frames may have material added for strength. These changes shall not affect frame geometry. Only bolt-on components allowed.

A separate Extreme Dirt Track Banquet will present # 1 Plates to all Champions including Pro, Pro-Am, A, B, C, Plus, and Youth Classes.
RACE PROCEDURES
All events will run qualifying heats and a main event. The number of riders in heats will be determined by track width, with a minimum of 60” per machine. All riders in heats will get a front-row start.
A rider must start in a heat or consolation race to qualify for the main. *(i.e. Come to the line, with machine when # is called, and roll across the line when the race starts.)
If there are more riders in a class than can be accommodated on the starting line, multiple heats will be run. If there are 21 or more riders, one or more LCQ’s will be run.
Riders will be divided into equal groups based on current point standing, preventing all the best riders from racing in one heat.
Heats will be timed. The winner of the fastest heat will get first pick in the main, and the winner of the next fastest heat will get second pick for the main, and so on.
Equal numbers of riders from each heat will transfer to the main, leaving a fewer number to transfer from the LCQ’s. No more than 20 will participate in the main.
Starting lines must be 24’ apart, with the penalty line 24’ behind the last starting line.
A rider must be ready when called to the starting area. If not ready, he is allowed two minutes after the starters call to make minor repairs. Afterward, if he still is not ready, he is excluded from the event. * (A rider or pit crew member must notify a race official if they are not in staging when their number is called to receive the 2 minutes).
Any rider whose tire crosses the starting line before the start will be moved to the penalty line, and the position left vacant on any subsequent start or restart of the race. *(if push start is required, permission must be obtained from referee or staging official to cross line prior to start).
Facilities permitting, the referee may use light(s) or flags to start a race.
Any race stopped with two laps or less completed will require a complete restart in the original positions. A rider who was determined by the referee of the event to be the primary cause for the event being stopped, will be required to restart from the penalty line.
If, in the referees opinion, it is necessary to stop an event after at least 60 percent of the total distance has been covered, the race may be considered completed. Riders will be scored according to their position on the lap preceding the one during which they were red-flagged.
At the referee's discretion, the race may be resumed and riders will be started in staggered single file in the positions they held on the lap before the event was stopped. Referee may require riders to stay single file until passing a designated point.
When an event is stopped (red-flag) before being completed, riders only can adjust or make repairs on their quad. The quad must remain on the track during this time. Mechanics are not allowed to wrench on the quad, but they can assist the rider with tooling. Riders, however, must be in their assigned positions and ready to race four minutes after the red flag (eight minutes during final events) or when the track is safe for racing.
Any rider who leaves the track after the start of a race will be disqualified for that race. A rider is allowed to work on their quad under a green flag condition only if the work is performed in the designated pit area.
If a race was stopped because riders were down, the first rider down is placed last in the restart, etc., with the last rider down behind the last rider who did not fall. If for any reason a rider does not complete the red-flagged lap, he too will be placed in the rear of the restart in a position respective of his stoppage.
If the race is called complete, the riders will be scored in the position in which they would have restarted.
