All Minors (competitor or spectator under 18) at the event site MUST be accompanied by at least one parent (or legal guardian) during the entire course of the event.
For Minor Competitors, BOTH parents (or legal guardians) MUST sign a Minor Liability Waiver before the minor may be allowed to compete. Proof of full legal custody is required for single-parent households.
A parent (or legal guardian) of any Minor Competitor MUST remain at the event site until the completion of the event.
Copies of the Minor Liability Waiver are available before events upon request from the Solo Director.

2. 4 Wheel Drive or High Center of Gravity Vehicles

Any vehicle on light truck rated tires.
Any vehicle with a 4-wheel drive transfer case.
Any full size van.
Any mini-van.
Any vehicle with a lift kit.

3. Uncompleted Work Assignments
All competitors MUST complete their scheduled work assignment in order to be eligible for event trophies or year-end points. If a competitor does not complete their work assignment during their scheduled time, the competitors scheduled runs will be forfeited and entry fee will not be refunded. If the competitor does not complete their work assignment after completing their scheduled runs, the competitor will be disqualified from the event, will not be eligible for trophies, and will not score any points towards year-end awards. If it is documented that a competitor has skipped work assignments at more than one event during a season, the competitor will be subject to possible exclusion from competing in future events per the Solo Chairman’s discretion.

4. Car numbering and lettering.
Per National rules, numbers must be a minimum of 8" high with a 1.25" stroke. Class letters must be a minimum of 4" high with a 0.75" stroke. They may be made of any durable material that contrasts with the car’s paint. We will allow tape as long as the finished product meets requirements and are on the car before tech occurs. The correct width tape in different colors will be provided at the event for people who don’t bring their own numbers. It is expected that if it is not your first season that you have a set of numbers other than tape.
“Shoe polish” numbers will not be allowed.
Positioning the numbers on the car’s paint is preferred, but numbers may be placed on the car’s rear-side windows with the following conditions: The numbers/letters must meet size and material requirements (no shoe polish). The window must be adequately tinted so high contrast is maintained. If the tinting allows much light/detail to pass through the window, then the high contrast is lost and won't be allowed. The numbers and letters do not have to be the same color, as long as high contrast is achieved. So, panel numbers that are the correct size, and have high contrast with the panel, can be used with a different class color to maintain contrast with the car color.

5. Helmets
There will be a limited number of loaner helmets available.
Helmets meeting the following standards must be worn while on course:
All helmets meeting the latest or two immediately preceding Snell Foundation standards (SA2020, SA2015, SA2010, SAH2010, M2020D, M2020R, M2015, M2010, K2020, K2015, K2010). SFI standards 31.1/2020, 31.1/2015, 31.1/2010, 41.1/2020, 41.1/2015, 41.1/2010. FIA Standards 8859-2020, 8860-2018, 8860-2018-ABP, 8859, 2015, 8860-2010.

For maximum protection, helmets must fit securely and should provide adequate peripheral vision. The chin strap must be securely fastened.
