uneven number of cars to equally distribute between heats, the last cars will be placed at the
back of the lowest numbered heats. Any cars not represented at the drawing shall be placed at

events, field maximum size and other pertinent information at the drivers meeting. In the event a
“B” main is required the top 16 in the passing points will be locked into “A” Main.
F. The lineup posted on the pit bulletin board when cars enter the racing surface for any race shall be
the final line-up. In the event a car drops out of the line-up for mechanical reasons, the balance of the
field shall move straight forward. The exception being, if 2 cars drop out from same row, prior to
green flag.
G. The start will be official only upon the starter signaling with the green flag. In the event a pace car is
used, all cars shall take their proper position behind it. In the event a pace car is not used, the pole
car will set the pace which shall be consistent with track conditions and as required to keep the field
in formation. DTGS shall be empowered to disqualify or penalize any driver violating this rule.
