** AGE WAIVER: An age waiver is a provision that allows a driver to compete in a division or divisions they would not normally be eligible for due to age restrictions. The waiver enables the driver to "move up" to a higher division, provided the following conditions are met:

  • Parental Permission: The driver’s parent or legal guardian must give consent for the driver to move to a different division.
  • Approval from Track Officials: The track director and officials must approve the decision, ensuring that the move is in the best interest of safety and competition.
  • Proof of Ability: The driver must demonstrate that they are capable of competing at the higher level, often by showing sufficient skill, experience, and safety awareness.

This system allows younger drivers to participate in more competitive divisions if they are ready, helping to facilitate their development and progression in the sport.

**  All Participants in our Kids Divisions are permitted to use personal RaceCeivers during practice and qualifying sessions. Track Officials will notify parents and drivers if Officials will be controlling the RaceCeivers during heat races and main events.  

**Track RaceCeiver Channel: 454.000

** Regular gas is defined as 87-octane. All karts that are required to run regular gas will be required to purchase fuel from Propst Superette #6. We will be checking the top 5 mowers to make sure they are running regular gas from Propst Superette #6.
