2018 Track Rules


*** For 2018 both Volunteer Speedway and 411 Motor Speedway rules are the exact same ***


Drivers, Crew Members and Fans: Rules for each respective division are posted for your convenience here on the Volunteer Speedway website. Drivers especially, make sure you are familiar will ALL RULES!!! Above you will see respective rules for each section that you will find by scrolling down the rules page.

We have tried to make racing as competitive, affordable and safe as possible for all racers and fans. VOLUNTEER SPEEDWAY’s rules and procedures are explained in detail. The management of VOLUNTEER SPEEDWAY wishes all of you a successful and safe 2018 racing season.


For the 2018 racing season, Volunteer Speedway has entered into an alliance with other East Tennessee racetracks – 411 Motor Speedway, Tazewell Speedway, I-75 Speedway, Boyd’s Speedway, Crossville Speedway, and Wartburg Speedway – regarding penalties assessed at the respective tracks pertaining to fighting and misconduct involving competitors; such as deliberately ramming into another race car either on-track

Anyone/everyone (driver/crew member/fans) involved in an incident which results in violent physical contact (throwing punches/wrestling), will be suspended. The time-frame for a first offense is a minimum of two weeks, unless further time is deemed warranted (respective track’s discretion). While you’re under suspension you will be suspended by all alliance-participating tracks under this mutual agreement for the set amount of time handed out. In other words, you won’t be permitted to race anywhere in East Tennessee.

If you enter someone else’s pit and start a fight, you’re gone period and suspended. … Each track will make a judgment call regarding individuals involved and suspensions. If a fight takes place away from both parties’ pit area, everyone is considered guilty and will be suspended.

All tracks entered into the alliance related to fighting and misconduct hope to let it be known that physical violence will not be tolerated. Anyone/everyone (driver/crew member/fans) needs to seriously think before getting into any confrontations at tracks. Because anyone/everyone involved in fighting or misconduct will suffer the consequences (suspension/and possible monetary fines before once again being allowed to compete).
