IT IS THE RESPONSIBILITY OF EACH COMPETITOR TO READ, UNDERSTAND, AND COMPLY WITH THESE RULES. These rules are neither foolproof nor exhaustive. They are intended to provide fair and competitive racing for all who participate in this division. The spirit and intent of these rules is the standard that will be used for competition at for the SW Super Truck Series.
   Officials are authorized to decide if an equipment change or addition is an attempt to circumvent these rules or provide an unfair advantage. Officials can disqualify any entry in violation of the spirit and intent of these rules. Decisions will be based on common sense, consistency, impartiality and fairness. If there is disagreement or dispute regarding the meaning, interpretation, or application of these rules, officials’ decisions shall prevail.
     If these rules do not specifically say that you can add, change, or modify something, then you should consider that addition, change or modification illegal. Any questions about the legality of an addition or modification not covered by these rules must be answered by the rules committee for the SW Super Trucks in writing, and their decision is final. Officials have reserved the right to confiscate any illegal components at any time. Any driver found to be using illegal components will be considered to have been competing unfairly to that point in the season, and all accumulated points for the season earned at ALL Tracks the trucks race at will be forfeited. This is for Blatant rules violations. And no exceptions or second chances
  Track officials can alter or amend these rules, after agreement with southwest super truck officials have been reached in the interests of safety, cost control or fair competition. No implied warranty of safety shall result from the publication of, amendments to, or compliance with these rules. The safety of each racecar and all equipment is the complete responsibility of the driver/owner, and the driver/owner acknowledges this responsibility by participating in any racing activity.

2.0If a Super truck is found in violation of a rule and the truck has been teched in the past the only assumption the rules committee can come to is that that truck has been in violation ever since the previous tech and will result in a loss of all points earned at ALL tracks the truck raced. ¾ of the rules committee must be in agreement that the violation is intentional, so it is highly recommended that once you have been teched and before you change anything you should consult with a member of the rules committee member and have them sign off on your change, that way you will be covered.
