Driver Meeting
- A. It is the responsibility of ALL drivers to attend the drivers meeting. All schedules, start times and formats for the night will be discussed during the meeting. All drivers not attending the drivers meeting will be on their own to figure out the information needed for the event.
- B. PENALTIES FOR TROUBLEMAKERS - There is no fighting on or at the track. Anyone running into anyone else on the track intentionally or using their car as a weapon will no longer be able to compete in the Series for that night and will be evaluated by series officials after the event for a possible 1 race penalty. If the 1 race penalty occurs, This will be the 1st Offence. If this occurs at the last race of the season, a penalty will be served at the first race the following year. 2nd Offense will be INDEFINITE SUSPENSION. (Which means for however long it takes for attitudes and thought processes to change. Could be 2 weeks, 2 years, or forever). This is all determined by the Series officials. Each driver is responsible for their crew, and the same rules apply for crew members as well as the driver.
