* Treat the other driver the way you want to be treated.
* If you have a problem with another driver or team, take it up with an official (in an civil manner) not the other driver or team. If anyone starts an altercation with anyone else (right or wrong) they will be fined $500 and not be allowed in the competition area until the fine us paid (the instigator only not the entire team).

KOTS has the right to inspect vehicles and support vehicles at anytime for rule violations.  This includes tear downs and/or PNG engine measurements.  Refusal to allow an inspection or tear down will be considered the same as a performance rule violation and will require the same penalty.

If a racer believes another competitor in the same class is in violation of a rule, he or she may protest that racer for further inspection. The protesting racer must have a tech card for the current race. The racer making the claim must specify the violation to be checked for and put up a $500 protest bond plus any additional costs. Additional costs include but are not limited to damaged parts, gaskets, and reassembly fees by a professional shop of the car owners choice. Maximum shop fees will be set at the time of protest to not be excessive for the work to be done at the judgment of the KOTS president. If the racer is found guilty of that rule violation, the claimant will get his protest money back.

In the event of inclimate weather, the decision to call a race is the decision of the hosting track.
