hand out to signify a wave prior to the start of each race.
2. The starter will signal the field to line up either single file for the
hot laps, tire warm ups or the restart of all events after the first green
lap has been completed. The starter will signal for double file starts for
the start of the main, heat and last chance races. Protecting the quality
and enhancing speed of our shows requires that cars stopping to work on the
car before the green flag is thrown will result in your car starting at the
rear of the field.
3. The pole car must set a reasonable acceleration for the starts in
all racing events. This decision will be made by the Starter and/or Chief
Steward and will not be protest able. If you cause a Yellow or are involved

a yellow flag, and that car is ready to restart by the time the next green
flag is thrown, no yellow flag laps will be counted against those cars. Those
cars will still be on the same lap. The only penalty is those cars involved
in the yellow start at the rear of the field.
2. Line up restarts (yellow flag caused restarts): Line-ups revert back to
the last fully completed green flag lap in the lead car. This method will
determine the reline up of all events for all cars. Lap cars remain in place.
This is the policy regardless of whether we are counting yellows or not.
K. Restarts:
1. If any car spins in the first lap of any event, that car must move
to the rear of the field. Then the event will be restarted.
2. Restarts will be single file after completion of the first official lap.
3. Lap cars remain in their earned positions for all restarts.
L. Race Completion:
1. The race is completed when the checkered flag is waved.
2. Final standings will be determined by the sequence in which the cars completed
the event. Cars not completing the event will be ranked in order by total
laps completed and sequence of completion.
3. If a race is stopped by the use of the red flag and is ruled complete,
final standings will be determined by ranking all cars in order by total
laps completed and sequence of completion through the last official race
lap with the exception that cars causing the stoppage will be positioned
in the back of their last lap completed. Finishing order will be the same
as the line up, if the racecar had been restarted. The official decision
to restart a red flagged race is not protest able.
4. In the event the scorers are unable to conclusively determine any difference
in physical sequence of two or more cars, SRL officials are empowered to
declare a tie for the positions involved. The officials’ decision as
to whether to declare a tie is not protest able.
M. Special Events: Special events such as but not limited to PIR,
East West or Triple Crown events may bring forth special rule modifications
to satisfy the terms of the joint club agreements, contracts and other conditions
that required deviation from normal rule procedures. The Supermodified Racing
League continually reserves the right to negotiate these special terms for
special events.
N. Tech Inspection after the Events:
1. The top Four finishers and any other car designated will report to the
impound area. This area will be indicated at the driver’s meeting.
2. Failure to report immediately to the impound area will result in automatic
disqualification from the event, and may loss of monies and points. Fuel,
C.I.D. or rule infractions will carry the same penalty.
O. Cancellation of Program: When a program is stopped on account of
weather or other conditions over which the promoter has no control the program
will be considered completed for points tabulation if over 50% of the
“A” main competitive laps have been completed.
V. FLAGS
A. Green Flag:
1. Start of the event. Any car taking the first green will be considered
officially started and will be scored accordingly.
2. The starter will hold up one finger to indicate the green flag will be

finishing order on the basis of the number of laps completed, but will not
be awarded passing points.
B. Yellow Flag:
1. Yellow flag means caution. There will be NO racing to the yellow
flag. Maintain positions; do not pass the car in front of you. The
driver of the lead car will hold the pace the starter wants, and the rest
of the field will form a single line behind the lead car (until signaled
otherwise). Passing under the yellow flag permitted only by permission of
the starter after instructions and/or concurrence has been received from
the Chief Steward. Unauthorized passing under the yellow flag will result
in a penalty decided by the Chief Steward.
2. Cars stopping so that they may be worked on or entering the infield while
the yellow flag is out will start at the rear of the field, unless the decision
to stop the cars is an official’s decision. Then the car can retain
its position.
3. Restarts will revert back to the previous green flag lap, meaning that
once a yellow is thrown, the restart lap will be the last complete lap of
the lead car, and any driver involved in an accident or causing the yellow
to be displayed shall start in the back of the field upon resuming that race.
4. Any car stopping on the track will go to the rear of the field during
a yellow.

using hand tools only while on the track under a red flag. The driver must
be out of the car for refueling unless the crew has a fire extinguisher or
bucket of water present. Tires may be changed on the track only if the car
cannot be pushed with a push truck (see Section VIII. B. 4.). The car will
go to the back if a tire is changed or if the car is not ready when the yellow
flag is out, calling for a restart. Any tire changes require tech approval.
3. Only three (3) crewmembers per car, are allowed on the track, with proper
passes and when authorized. Must be SRL members.
4. Cars will be restarted according to the last lap completed by the leader

B. Qualifying:
1. One warm up lap, two qualifying laps. The faster of the two qualifying
laps is the time given for that qualifier.
2. Cars must be ready when needed or face fines or penalties for continued
late arrivals or delays. If you are more than three cars out of your draw
spot you will lose one qualifying lap. By the end of the qualifying session
you must have qualified or lose the privilege of qualifying that day.
C. Heat Races: The number of cars at each event will determine the
number of heat races.
D. Main Event Number of Laps:
1. When car counts exceed SRL or track main event maximum car count policies
then Last Chance races are run.
a. SRL reserves the right to add or deduct cars from the starting fields
as necessary to meet special event requests and for safety reasons.
