Mail Reports and Points Fund Money to:
Danielle Day – 5950 Lum Rd, Attica, MI 48412 [email protected]

Referee Duties: Referee must send event report to the points keeper within 3 days after the event. Report shall include date and type of event, results of each class and number of riders, and check or money order for the points fund. Points fund check shall be calculated at a rate of $4.00 per rider.


General Rules:
The following are supplemental to, or part of, the AMA/ATVA Rules and Guidelines. All other rules and guidelines applicable to the event shall be derived from the AMA.ATVA rulebook/guidelines and AMA/ATVA rules supersede in case of conflict.
A rules committee shall be composed of the ATV Chairman, ATV Congressman and Rider Representatives. The ATV chairman will break all tie votes. Rule changes and additions may be submitted, in writing for consideration at any time during the year, but if adopted will not take effect until the following season.
Rider representatives will be appointed at the annual sanctioning meeting. They will be required to represent the riders, and will work with the chairman to advance all phases of the sport.
Youth racers 15 years and younger may race in more than one big track class per day.

ATV Specifications:
Per ATVA Guidelines - All ATVs shall be fitted with a tether type engine kill switch.
Number plates and backgrounds should be white or black contrasting combination. Number plates for event scoring are required on the front and rear of the ATV. (Note, the promoter is not responsible for mis-scoring when numbers are difficult to read, it is the rider’s responsibility to ensure that the numbers are easily readable at a fair distance, see AMA/ATVA rule book.) Below are commonly accepted ways to number your ATV: FRONT: White background/Black numbers 8” high REAR: White background/Black numbers 8” high, mounted to the rear grab bar or riders back. Numbers are also highly recommended on rear fender deck and riders back also.


Riders shall earn full points on any race day that is the only points paying event in the district on that day even if they are the sole rider in the class. On a day when two (2) separate tracks are paying points within the district, a full class constitutes having a minimum of 2 riders and is required to pay full points. If less than 3 riders sign up in a given class on a day when 2 separate tracks are paying district points, ½ points will be awarded for a finishing position.
On the day of a nationally sanctioned ATV event held within District 14, that event will be the sole points paying event for that discipline in the District 14 ATV’s on that day.
Championship awards will be presented at end of season or series, and points fund will be distributed until fund is spent in full on above-mentioned awards. The number of awards given will be based on participation in class.
In the event that a race is dubbed “double points”, the points will count as 2 separate race finishes instead of 2 times the total points possible. Example: If rider wins a “double points event”, he/she will be awarded 2 race results worth 25 points each (25 + 25).

On the scheduled day of a MATVSCS race, it will be the only points paying MX race within the District for ATV’s.
Series Championship awards will be offered for each class unless noted otherwise. If the MATVSCS consists of more than 6 races, the top 81% of race dates will be counted for championship points. If there are 6 races or fewer, all events will count toward the year end championship. A rider must attend a minimum of 51% of the race dates in a particular class to be considered eligible for Series Awards (this does not guarantee an award).
In the event that a class must run qualifiers, the LCQ will be run before any class runs a 2nd moto in the schedule order. There will be a minimum of 2 motos in between a rider’s qualifier and LCQ ot a rider’s LCQ and main event. Overall event scoring will use national qualifier tally methods as used in ATVA National Events.
In the event that a promoter’s starting gate holds less than 20 ATV’s; and there are more class entrants than available gates, Moto 1 will be split into groups so that each riders has a gate for the start of the moto with each group starting on separate gate drops. In moto #2, all riders will start on the same gate drop. The promoter will line riders up on a second row, behind the first row based on Moto #1 finishes in order to field a full gate of 20 riders.
In the event of a tie in year end points for the MATVSCS, the tie breaker will be based on the 2 rider’s last head-to-head match-up. The rider finishing in front of the other rider will break the tie and assume the higher position.

All events scheduled for points will be accumulated towards division championships and year-end awards. See the points schedule below:

ATV MOTOCROSS & Michigan ATV State Championship MX Series

General Information
More than one class may be on the track at the same time. However, in the interest of safety no more than 2 drops of gate may be used to start a moto. If number of entrants exceeds limits of 2 date drops a second moto must be scheduled. (Not counting practice sessions which may be run together regardless of number of entries as long as it is deemed safe by the promoters.)
Prizes for all amateur and youth classes will be limited to trophies or dealer checks to a dealer of their choosing. Entrants of the “A” and ‘age’ classes may receive a cash payback directly to the rider, and all paybacks shall be on the same scale as the corresponding motorcycle class payback.
Novice class © riders’ performance will be reviewed on a continuing basis. After 4 wins, a rider will automatically be advanced. Riders who are outclassing the field may also be advanced from the C class at the discretion of the ATV Chairman and Rider Representatives. The Novice class © is for the introduction of new riders and riders of this class will be eligible for daily awards at every event.
Youth riders (15 and younger) on the big track (excluding Schoolboy Jr and Sr) may ride in more than one class per day on the big track.
New Promoters wishing to host an MATVSCS event - If a new promoter/club wishes to host an MATVSCS event, will receive the last date pick for their first 2 seasons hosting the event (unless another new promoter joins in afterward) - new promoter/club implies a promoter/club that did not host an MATVSCS event in the previous season.
In the event a rider gets DQ’d from an event for any reason, that race must be used in their year end totals and cannot be used as a ‘dropped score’.
