The rules and regulations set forth herein are designed to provide for the orderly conduct of racing events and to establish minimum requirements for such. These rules shall govern the condition of all in these events. Doe Run Raceway warns everyone racing is dangerous. You could be injured or killed. Even though we carry insurance, participate at your own risk. No expressed or implied warranty of safety shall result from this publication of rules. They are intended as a guide for the conduct of the sport and are in no way a guarantee against injury or death to participants, spectators or others.
Track management reserves the right to add, amend, suspend or adjust any rule or procedure which they deem necessary to aid in the production of racing. The omission of any rule or procedure is not by any means an authorization to any participant to assume legality or permission. It is best to get the approval from management rather than be disqualified due to assuming. No equipment will be considered as having been approved by reason of having passed through tech inspection unobserved. All cars must be tech/safety inspected prior to competing. All cars not meeting minimum requirements as set forth in these guidelines will not be allowed to compete. All cars subject to tech inspection at any time.
For the purpose of these rules, all competing classes are referred to as “cars” .
Only one vehicle per race car is allowed in the pit area of Doe Run Raceway. Doe Run Raceway, Inc. is not responsible for damage to personal vehicles.
For insurance purposes, the pit area must be cleared within 60 minutes of the completion of the race program.
We are looking forward to a safe, fun season for everyone. By working together, following these guidelines, we can accomplish this goal. Please feel free to contact the raceway at (573) 756-8889 if you have any questions. You may also
e-mail your questions to firstname.lastname@example.org
