2025 RULES
RULE #1 – All studded motorcycles are required to have front and rear wrap around ice racing fenders.
Fenders must be of sturdy construction, cover the full width of the tire, so that NO screws are visible
when viewed head on. The cross section of the fender must be of a curved design for more strength
and better protection than a flat fender would offer. Flat cross section fenders may be allowed on a 1
week grace period if inspected by an official and found to be soundly built and in good condition. The
front fender must extend from the fork legs down around the front tire to a point not more than 2”
higher than axle height. The rear fender must extend from a point on the rear tire vertical from the axle
down around the rear of the tire to a point not more than 2” higher than axle height. Maximum allowed
distance between fender and tire is 1 1/2”.
RULE #2 – Any racer caught using drugs or alcohol while racing will be disqualified. UMIRA reserves
the right to do mandatory breathalyzer checks on random classes just before their final. Refusal to be
checked or a blood alcohol content greater than .025 will disqualify racer. For first offense the racer
will be disqualified for that day only, but will need to be checked at each race for the next calendar
year, at sign up, and before their final. If it is their second offense, they will be banned for the rest of
the season and lose all points.
RULE #3 – No sidecars or outriggers unless there is a class for them.
RULE #4 – All studded classes are allowed to use only screws with a single screw slot and a maximum
head height of 3/16”. Screws may be sharpened to a like new condition when dull, but basic shape
and function cannot be modified in any way. Screws may be tipped, but screw head must still come in
contact with tire and no spacers are allowed under screw head to increase effective head height. 1/4”
tall screws are NOT allowed.
RULE #5 – All ATVs must display an ORV Sticker, or the equivalent if from a neighboring state. If not,
you can be ticketed by a DNR Officer.
RULE #6 – All machines must have a functioning rear brake. All studded QUAD’s must also have
working front brakes. Studded QUAD maximum width is 51”.
RULE #7 – All studded ATVs and Rubber ATVs that are allowed to run shortened swing arms and
Hoosier type tires will be required to use nerf bars that extend to the outside edge of the rear tires. We
recommend that they be used in all ATV and Quad classes. Keep outside front corners of nerf bars
rounded so they will not hook on another machine, and function as they are intended.
RULE #8 – All ATV classes (excluding Utility classes) must have a functioning tether switch installed.
Functioning will be defined as having the tether cord attached securely to the rider, and when the cord
is pulled free of the switch, the ignition system must be killed completely, preventing the spark plug
from firing.
RULE #9 – ATV bumpers may be modified or replaced, but must still have a similar appearance, shape
and function as the O.E.M. bumper. If any weights or accessories are added to any race machine,
they must be securely fastened, or entry may be disqualified for safety reasons. No one allowed on
track without a helmet on race day. No traction devices on feet.
RULE #10 – 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 machine is
class legal, but will start at the rear of the field upon board discretion. Once a race is started, there can be no changing of
machines. Start of race will be defined as the first attempted start, even if it results in a complete
restart.
RULE #11 – No traction devices or abrasive materials may be used on any tires of a rubber class
machine.
RULE #12 – Stock classes must use stock type over the counter tires. Worn edges of knobs may be
cut square again, but the basic shape and function of the knobs may not be altered. All other Rubber
ATV classes may cut and/or soften their tires in any fashion.
RULE #13 – Properly fitting helmets with a minimum of a D.O.T. approval rating (UMIRA recommends
helmets with a Snell approval rating) are mandatory in ALL classes for ALL racers. Properly fitting
chest protectors are mandatory in all studded ATV classes, and for any racer under the age of 18,
regardless of the class they are competing in. UMIRA recommends the use of properly fitting chest
protectors and neck/spinal support devices by all racers in all classes. Sorel type boots will be
allowed. Leather MX type boots are recommended. Tennis shoes and all nylon upper snowmobile
boots will NOT be allowed.
RULE #14 – No side-by-sides will be permitted to race due to insurance limitations.
RULE #15 – Number and Number Plate Requirements – ALL classes must have a minimum of 6″ tall,
black numbers on white backgrounds. ATVs must display 3 plates. All hung on front, rear, and right hand side. Right hand side number plate must be clearly
visible with rider seated on the ATV. Motorcycles must display plates on the front, and both sides. The
intent of this rule is to make it easier to score the race vehicles accurately.
RULE #16 – Any class with 10 or more riders, TIME PERMITTING, will run a consolation race for those
who didn’t transfer to their final.
RULE #17 – Any class with less than 3 entries may be combined with another class or not run at all.
Any class with less than a 3 rider average in a season will not receive end of season awards.
RULE #18 – If a rider wants to enter in more than one class, s/he must pay an entry fee in each class.
RULE #19 – Class jumping is allowed as long as the racer and race vehicle meet all class
requirements.
RULE #20 – The Grand National Points System will be used for scoring and awarding championship
points. 20 pts – 1st, 16 pts – 2nd, 13 pts – 3rd, 11 pts – 4th, 10 pts – 5th, 9 pts – 6th, 8 pts – 7th, 7 pts –
8th, 6 pts – 9th, 5 pts – 10th, 4 pts – 11th, 3 pts – 12th, 2 pts – 13th, 1 pt – 14th and down. Heats will be
scored at half points of features. If you can stage your machine on the starting line and “take the start”
of any given race, you will receive 1 point, regardless if you complete the 1st lap or not, even if your
machine is broken when you start it. Championship points will be paid out according to your actual
finish position, no skipping over non-UMIRA racers finishing ahead of a UMIRA member. Season ties
will be broken by giving the higher position to the rider with the total highest finishes. If that fails to
break the tie, both riders will be awarded the position.
RULE #21 – There will be one throw-out race. At the end of the season your lowest-scoring race is
thrown out and excluded from total points.
RULE #22 – Heat starting position will be determined by random computer pick. #1, 1st choice, #2,
2nd choice, etc. Feature start will be determined by finishing order in heats. 1st heat winner, 1st
choice. 2nd heat winner, 2nd choice, etc. Anyone transferring from LCQhas last choice. If we don’t
have enough entries to run a LCQ, everybody races in the final IF TRACK CONDITIONS PERMIT.
RULE #23 – If two or more riders go down before the penalty marker it is an automatic restart. EVERYONE involved in
the incident will go to the penalty line, no matter who is at fault. The rest of the field will start in original
order. If one rider goes down before the penalty marker, flag-mans discretion. If the race leader has 2 or more laps completed,
racers will be started in order of the last completed lap in a single file rolling restart.
RULE #24 – Anyone that causes a restart, for any reason, or jumps on the line, will be restarted from a
penalty line. Penalty line #1, and 2nd row start lines will be decided on race day by a track official.
Racers on the penalty line or 2nd row will be started on their own start by way of official. Racers
starting from row #1 will go to penalty line #1 for 1st offense and if they commit another penalty line
offense before 1 lap is completed, they will go to penalty line #2. Line jumping will be defined as rolling
forward before start light turns green. Anyone starting from a penalty line on a restart that doesn’t
result in at least 1 full lap being completed, must go back to their penalty line on the subsequent
restart.
RULE #25 – If the majority of the racers in a class protest the riding conduct of another rider, the first
complaint will result in a verbal reprimand, the second complaint will result in the rider being scored
last in that class for the day (Black Flagged). The third complaint will disqualify that rider for all classes
that day.
RULE #26 – Pit racers will automatically be disqualified for the day and no entry fees returned. Pit
racing is defined as exceeding the normal walking speed of a person.
RULE #27 – Teardown fees will be at $100.00 for 2-strokes, and $200 for 4 strokes. You have to be
entered in the same class as the entrant being protested to be eligible to tear them down. Owner of
the protested machine can be present at inspection, and is responsible for disassembly. UMIRA
officials are the only other people allowed into the inspection area. The Board reserves the right to tear
anyone down at any time, without a tear down fee, if we feel that it is necessary. Anyone refusing to
tear down without good reason will forfeit any points, money, or trophies earned that day. If the
protested machine is found to be legal, the owner of the machine is allowed to keep any collected tear
down fees. If the protested machine is found to be illegal, the protester gets their tear down fee back.
If it is their 1st offense of the year, the protested party gets disqualified for that race. If it is their 2nd
offense, they are banned from UMIRA competition for the balance of the season and are stripped of all
championship points earned with that machine.
RULE #28 – Get to the races early. Sign up will be from 8:00 – 10:00 a.m. Practice will be from 10:00 –
10:45/11:00 a.m., unless conditions don’t allow. Riders meeting to follow, will be at approximately 11:00/11:15 a.m. No practice until you are signed up. No entry fee will be returned after the first race starts. Races start after riders meeting at approximately 11:30.
RULE #29 – All entry fees will be $10.00 for youth and non-paying classes. All additional classes will
be $15.00.
RULE #30 – Membership dues will be $50.00 per person. Family memberships are $100. Your
membership gets you into the pits for free every weekend. If you are not a UMIRA member, you may
race for an additional $25.00 Day Fee. This fee allows the racer to compete in as
many classes as they desire for THE DAY. UMIRA season members will be awarded championship points, but no points will accumulate until dues are paid. These fees pay our expenses during the season. Please support our association by
joining early.
RULE #31 – A promoter of a race may put additional money towards the payback of paying classes
with the approval of the UMIRA officers and directors. Kid’s classes will be strictly trophies only.
RULE #32 – All decisions will be handled by the board members present on day of complaint. Conduct
of the event will be controlled by the President/Vice President. ALL DECISIONS MADE ON RACE
DAY ARE FINAL.
RULE #33 – 4-stroke engines may be bored and/or stroked to any size if you like, but its ACTUAL
DISPLACEMENT determines what classes it is legal to race in.
RULE #34 – Pro classed riders are eligible to race in a novice class, if it falls into a separate category.
For this purpose, the categories are: Rubber ATV, Studded ATV, and Studded Motorcycles.
RULE #35 – Any racer failing to make start lineup on the initial start or restart will receive a 2 minute
grace period before starting the class without them, if the pit steward is notified. If the pit stewards are
not notified there will be no 2 minute grace period given. This policy will be used in all races, including
LCQs. If the race is restarted with no laps completed, and a late racer arrives at the start line, they
may be put back into the race. If a racer fails to get to the start line before the start of the race, they
will receive last place points, and be eligible to compete in a LCQ, if there is one in that class. The
requested “2 minute” period will not start until the class is staged at the line. If multiple racers request
“2 minutes” the original riders requesting the delay may still start the race. There will only be allowed a
maximum of “3” grace periods (6 minutes) for the start of any race.
RULE #36 – If a racer leaves the boundaries of the racing surface during a race, they must not gain
any track position upon re-entering racing surface, or be disqualified. If a yellow light is displayed in a
corner, you must hold your position until you pass a corner with no yellow light displayed, or the flag
man with a green or white flag displayed. Failure to do so will result in loss of position(s) or possible
disqualification for repeat offenders.
RULE #37 – Kids classes – racers in these classes can have outside help until they leave the pit area
(for these classes only), and enter the racing surface. Once they are on the track, no assistance is
allowed.
RULE #38 – Any racer, at any race (with UMIRA boards permission), while competing in their normal
classes, can jump up into their next higher class of competition to see how competitive they will be at
that level, as long as their machine is legal in that class. An entry fee is to be paid for each class
competed in. All cash and trophies earned at that race will be awarded to the racer, but championship
points will only be awarded for their “normal” classes. The purpose of this rule is to encourage all
racers to move up through the competitive ranks as their skills and equipment improve. Also, as the
board deems it appropriate, they may move a racer up, or down in the competitive ranks AT ANY
TIME, to insure quality competition. If a racer moves up a class level (or down with UMIRA approval),
or gets moved by UMIRA, within the first two races, they will receive their “average points” earned in
their “new” class for the weeks they ran their “old” class.
RULE #39 – The only people allowed on the racing surface during actual UMIRA competition are
racers, UMIRA officials, and designated line workers. Racers are NOT allowed to do any shoveling or
sweeping at the starting line. After bringing their machine to the starting line, racers are allowed to use
only their hands and/or feet to sweep their starting spot.
RULE #40 – UMIRA officials and board members can act on any issue at any time.
RULE #41 – Fuel rule – The following are banned from UMIRA competition in ALL CLASSES. Alcohol,
nitrous oxide, nitro methane, Also banned are super chargers and turbo chargers. All engines must be

RULE #42 – The maximum sound limit allowed on all UMIRA machines is consistent with state law at
96 D.B., using the M.I.C. stationary sound test recognized and used by the AMA and D.N.R. Please
note that DNR wardens may do sound tests at some events, and if you fail THEIR 96 D.B. test, you
may be issued a citation. Its is up to the board to decide when or if, a race or machine will be tested.
RULE #43 – Any machine failing a sound test may get one warning before being disqualified.
Disqualifications will apply to all classes that machine was being raced in that day, including classes
that it may have been ridden by additional riders. The machine then has to pass a sound test before it
will be allowed to race again. Once you have received a warning, you are eligible for disqualification,
even at a later race date, if you fail a sound test.
RULE #44 – Prior to 8:00 a.m. on race day no race engines are allowed to be started. Please do your
practicing on a practice track. This will improve the quality of our track on race day.
RULE #45 – Performance Enhancement Accessories (IE. HRC, Pure Polaris, GYT) are not considered
legal in stock and visually stock classes, regardless of who sells them. For a part to be considered
“LEGAL”, it must be installed on the machine at the factory.
