PROCEDURE
* Once a racer takes the tree in qualifying they are counted in the ladder, will receive participation points and may not get an entree refund.
* All cars must be driven from the pit area to the starting line but may be towed back after a pass.
* Rules are subject to change and any combination that shows to have an definite advantage can be penalized to equalize the competition.
* Weather and time permitting, there will be 2 qualifying sessions. The quickest time will be the official qualifying time. Racers will be paired according to a pro-ladder. Driver with the quicker E.T. in the previous round during eliminations will have lane choice.
* Each car may only have 3 crew members in the staging area.
* Deep staging allowed at drivers own risk, no provisions made to hold the tree for the driver.
* If a race ends for any reason during a round of competition no points will be given for that unfinished round.
* Any minor intentional or unintentional rule infraction that does not cause a definite advantage will result in loss of any points and winnings achieved while in violation.
* Any intentional rule infraction done to gain advantage over the competition will result in disqualification a $3000 fine and suspension from all KOTS races until the fine is paid in full.
* A round does not begin until a KOTS official working the lanes says so.
* A driver does not start his burn out until an official says so.
* If a driver refuses to stage or is unable to stage or proceed to burnout after an KOTS official has told them to, the drivers will be disqualified during eliminations or loose their qualifying attempt for that round during qualifying.
* All drivers must be ready when called to the burnout box and must pull into his lane immediately when motioned up by an official or he will loose that round.
* If a driver double bulbs, the other driver does not have to pull up to the first beam.  He can make the other driver back out and pre-stage again.
* 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 competitor believes another competitor in the same class is in violation of a rule he or she may protest that racer for further inspection.  The racer making the claim must specify the violation to be checked for.  If the inspection requires a teardown of any part of the competitors car, claimant must put up a $500 protest bond.  If the racer is found guilty of that rule violation, the claimant will get his protest money back.  If the racer is found innocent the racer gets $400 for the unnecessary teardown and KOTS will get $100 for tech fees.
