In the event of a red flag, the race will be restarted on the starting line if one full lap is not completed. If one or more laps are completed, the riders will be started on the track and in single file in the order of last completed lap. Any racers involved in a red flag will be restarted in the second row or at the end of the line. Any racer who is responsible for 2 red flags in one race will be eliminated from that race.
A black flag indicates rough, illegal, or dangerous racing, which indicates disqualification and immediate exiting of the track by that rider.
A white flag will be waved when the first place rider is one lap from finishing the race.
The checkered flag will end the race.

13. Starting Line Procedures

The choice of position on the line will be determined by computer randomization.
When all machines are staged and ready, riders must be prepared as the starting line cord can snap at any time.
If a rider touches the cord, the race will be restarted and that racer will start in the back row with machine in neutral with a 3 second hold.
It is the rider's responsibility to be at the line and ready to race on time for his or her race. If you have an issue with your machine, you must have someone present at staging for you prepared for line up. You will have until the final machine in your race is set up at the line to get your machine there. The race will start as soon as the final racer is lined up. If you are not present at that time, the race will start without you.
No individuals are allowed to cross in front of the bungee cord during NWIRC competition unless they are NWIRC officials or designated line workers.
No shoveling or sweeping at the starting line.

14. Machine Legality

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 and number plates are fixed to the new machine per established guidelines.
Once a race is started, there can be no changing of machines. The start of the race will be defined as the first attempted start, even if it results in a complete restart.

15. Pit Racing

A 5 mph max speed limit will be enforced in all pit and spectator areas, and within 100 feet of any person or structure. This is a Wisconsin state law.
Any racer not in compliance will be disqualified and will forfeit their entry fees and/or points.
Absolutely NO hot dogging.
It is everyone's responsibility to report pit racing. NWIRC officials can't be everywhere, so help is needed to enforce this rule.

16. Noise Restriction

No race engines are allowed to be started prior to 7:00 a.m. on race day.
No racers are allowed on the race track on a machine prior to practice on race day, unless otherwise designated.

You must either work for points as described below or pay the opt out fee ($100/PeeWee racer and $200 all other racers) to qualify for season points. If you do not work your 2 shifts or pay the fee by the deadline you will forfeit your season points and any trophies or prizes associated with season winnings.

18. Work requirement for season points

All riders need to "work for points" twice to qualify for season points (no help, no trophy or $$). There will be chances for ALL riders to help. Jobs included will be; 3 setup workers, 2 tear down workers, 2 line workers, 2 parking/ garbage attendant, 1 tech assistant, track set up or plow assistants, 2 corner flaggers, race number board attendant, membership assistant.
Pee-Wee Points, No racers under the age of 12 are required to work BUT the parents or guardians are required to help with 1 race per racer. This is to ensure that parents understand how it works and to keep the club moving forward.
Work positions are on a "first come first served" basis and can be accessed using the sign up genius link on our home page.
You do have the option to opt out of working for your season points by paying opt out fee of $100 for PeeWee racers or $200 for all other racers.
- ***This must be paid by the end of day on the first scheduled race of the season.
Sign up will be open until week 4 (January 25) of the race season. You must sign up for your work positions prior to that date.
If you sign up for a shift and are unable to keep your commitment, for whatever reason, it is YOUR responsibility to find a replacement worker for your shift.
- ***If you do not show up or do not complete your whole shift you will lose your points for that race and the season!!

19. Placement of riders

Racers must compete in at least 50% of season races that were run to qualify for end of the year trophies.
Overall points winners in the B and C classes will be bumped up to the next class the following season.
Racers may choose to race up one class in a race.
- ***If you race up and place top 3 in that class, you will stay in that upper class and will not be allowed to race back down to the lower class.
If you win the A studded or A rubber for 2 consecutive years you will be ineligible to run that class the following year only.
NWIRC officials have the right to move riders up and down classes as seen fit according to ability, age, and experience.

20. Throw Out Races

When season championship points are tallied, you will have 1 throw out race. (I.E. if we have 8 points races, we will count only your best 7 finishes).
If you miss more than 1 race, all points accumulated will count towards your season championship points total.
If you are disqualified at any race, for any reason, that race cannot be counted as your throw out race.
There will be NO throw out race if we are unable to race a full season.

21. Mid-season Race

Mid-season race will always be the fourth SCHEDULED race of the season. This is the tie-breaker.
If the fourth race of the season is cancelled for any reason, the next race held will be the mid-season race.

22. Race Minimum

There is a minimum requirement of 4 riders to run a race, including Junior and Pee-Wee.
There may be exceptions to this, based on individual race/track needs and limits-will be at board's discretion.

23. Bumping

If you are a B or C class racer wishing to race up to the next higher class- you are allowed to race up one class, but please note, if you place (take 1st, 2nd or 3rd) in one race in that upper class, you will be bumped up and stay in that upper class for the remainder of the season.

Any rules can be modified by majority vote of officials at anytime.
Any challenges are to be brought to the board's attention.
Decisions of the board are final.
