top 17 cars are brought to the front pit area and checked for rule violations. Any car found not
adhering to all rules will be disqualified and will forfeit all winnings. The 11

th place car will then
move up in position. Each person is responsible for reading and following the rules. All rules will
be enforced. No official results will be available and no positions will be paid until the inspection
of the cars is completed. Any questions on the rules should be addressed to an official before the

the driver’s advantage to submit the entry form and fee early. Sign in will begin 4 hours before

early as possible to prevent any backup of cars signing in at the pit gate. Anyone arriving late will
be not allowed to race. If you arrive after the race has begun, you will not be allowed to race.
22. All drivers must be in the pit area at least 11⁄2 hour before the race begins in order to park the cars
on the track in their starting position. After the race has been completed, you will have to remove

count laps for the car. The lap counter must be checked in at the pit gate and in his or her position
in the lap counting area one hour before the start of the race. The lap counter must come through
the pit gate, not the grandstands, and should enter with the Enduro car and driver. Therefore, do
not assign someone to do this job who will not want to remain in the lap counter area and watch
the entire race. This person will have the responsibility of watching your car as it passes the flag
stand and recording every lap. Please chose your lap counter ahead of time and have them read
the lap counting instructions. They will not need a pencil or paper, but should have some idea of
what they are expected to do. Also, be sure that they get there on time. If they are late we will
not be responsible and it is your lap counting that will not be done. Alcohol consumption by the
lap counters will not be allowed during the race. Instructions, lap counting sheets and
pens/pencils will be given to the lap counters in the lap counting area prior to the race. All lap

children, friends, etc will be permitted in this area. Please make prior arrangements for child
care as lap counters children will not be allowed in the lap counting area.
3. Lap counters must turn in their lap board and scoring sheet to the officials immediately
following the event. If the lap board is not turned in on time, your results will not be official and
your car will be disqualified.
4. Lap counters are responsible for recording times that their car passes the start/finish line. As
soon as the green flag signaling the beginning of the race is given, write down the each time
your car passes between you and the flag stand on the blank line next to #1, 2, etc. on the
scoring sheet.
5. If the cars are not stopped for a red flag, continue writing every time your car passes the scoring
line. If the flagman stops the cars, write down the time whenever your car passes the scoring

line (either as it is stopping or when the race is started again). In other words, write down a
time each time your car goes by the scoring line.
6. If your car goes into the pits and then comes back out on the track later in the race, write down
the time the car passes the clock on the next empty line. Do not skip any lines.
7. Official results will not be available until after all car inspections are made and the lap counting
sheets have been checked and scored.
8. Remember that everything the announcer says is approximately 5 minutes late, but it is also
unofficial and he has nothing to do with the actual finish of the race.
9. There will be no drinking allowed in the lap counting area or pits during the race. If your car is
out of the race and you do not think it will return to the race, and would like an alcoholic drink,
please show respect for the others who are still lap counting and move to a different seating
