E) All Super Late Model

64)
Flags
A) Green: The green flag is the indication for the racing
to begin.
B) Yellow: The yellow flag is for caution, meaning there
is some kind of hazard on the racing surface. When the yellow flag is
displayed, racing stops. Any car continuing to race or failing to slow
down as soon as a caution is displayed may be immediately disqualified
from the event.
C) Blue: Yellow: The blue-yellow flag indicated that the
leader and/or faster cars are closing on a slower car. The driver
receiving the blue-yellow flag must move to the inside and allow the
faster cars to pass on the outside. A driver who fails to move down
after the move over flag is displayed will be given a warning. If the
driver again fails to move down, he will be black flagged and removed
from the race.
D) Black: The black flag is a consultation flag and
indicates that the driver must come to the pits immediately for
consultation with a race official.
E) Red: The red flag will be displayed when the track is
blocked or in cases where safety is a factor. In the case of a red
flag, all cars should stop immediately.
F) White: When the white flag is displayed, it means the
leader has started his last lap. If on the white flag lap the caution
is displayed, all cars, regardless of their location on the track,
will slow down and maintain position. We will revert back to the last
completed green flag lap and on the restart there will be a green,
white, checkered finish.
G) Checkered: When a checkered flag is displayed, it means
the race is completed. When the checkered flag is given to the leader,
the balance of the field receives the checkered flag on the same lap.

Caution Flag
A) All cars should immediately slow down upon seeing the
caution flag and lights. The cars will be scored using the last
completed green flag. There will be no racing back to the flag.

displayed will be subject to penalty including being sent to the rear,

the field.

that caused a caution will be allowed to line up at the rear of all
