Race Day Procedures

Qualifying

There will be no qualifying for 8 drivers or less; lane choice will be randomlyselected.
If there are 9 or more drivers qualifying order will be randomly selected.
Qualifying will be for 1 minute on a lane selected by the race director
Overall ranking will be determined by the total laps and sections.
Ties will be broken by the best lap time and then order of tech in.
Any driver who misses their qualifying time will be ranked in last position.

Race

Every race will be run as a main starting with the slowest ending with the fastest.
(I.e. C‐Main runs before the B‐Main, B‐Main runs before the A‐main.)
If 11 or less entries a round robin will be run.
If possible the number of drivers in each main will be equal, if not the mains will
be filled from the slowest to the fastest.
There will be a 2 minute warm‐up before each main.
Each driver will race for 3 min. on each color in JRL & B‐Production.
Each driver will race for 4 min. on each color in OPEN‐12 and Eurosport.
All lane changes will be 1 minute intermissions.

Marshaling

Drivers at the end of their main must marshal the next main or whenever called
upon.
The number of marshals must be the same in each main.
You WILL be disqualified for failure to marshal and will forfeit payout and points

Track Calls

For an unmarshalable car (I.e. in the middle of the straight in front of the drivers
panel).

Becoming a rider
A warning will be given for the first illegal track call and a 5 lap penalty for each
successive call.

Classification

After each main “A” drivers finishing position will be a result of the sum of the
laps completed and the last lap sections. The number of laps made can only be a
result of the lap counter; no lap correction is made for lane jumping (Riders) or
missed counting due to the cars brain. The race director must check the lap
counting system if there is a sustained problem. If a problem with the lap
counter occurs, then the race director must rerun the current segment. If the lap
counter fails to operate, the raceway must provide a spotter to count laps.

3 laps. You will be black flagged after the 3rd lap (Power will be turned off on
your lane)
Cars will be impounded after qualifying. Cars may not be touched by driver or pit
crew until the power comes on in warm up.
