Our Technical Inspector(s) word is final on car safety, personal safety equipment, and cars meeting these rules. If he finds something and tells you it needs fixed, get it fixed. If he finds a gray area or may need to implement a penalty, he will come to management, and we will come up with a decision and solution. Do not go to management if he told you something needs done or fixed with your cars. Suppose anyone, driver, crew member, family member, or team representative yells, argues, curses, or gestures anything in any way to our tech officials. In that case, that team will receive a penalty or be disqualified for that event. Being a tech is a challenging and thankless job, and they are there to make sure everyone is safe and on a level playing field.
NCTS has set these rules to keep everyone safe and as equal as possible for great competition. NCTS reserves the right to modify, change, or discontinue regulations in the interest of competition and safety. We want the best show possible for our associate tracks and our fans.
