Specifically section 1. Diver conduct

1.2 All competitors must attempt to keep two wheels on the racing surface at all times defined by the track limit lines. Drivers who repeatedly put more than 2 wheels off course will be penalized. If such off course excursions are deemed by race officials to have been initiated by any driver in order to gain an advantage, then the penalties assessed may be more severe and could include points deductions or DQ from the event. Race officials may take into account situations where driver error is obvious or instances where drivers were attempting to avoid contact. Should a driver who has put more than 2 wheels off the course pass another driver as a result, then the driver who passed must give the position back to the driver who was passed immediately.

No major changes here. This was mostly phrase change for clarification. Also the penalty types were updated to reflect the types we currently use.
