proper order until the lead car or cars reach this point. The Flagman
will be instructed not to throw the Green Flag until then. If the Official's judgment the front row car or cars are out of position a
Yellow will be displayed. Any further violation will result in the
offender to be placed a row back with the car behind the offender being

22. Any car not running at a reasonable
racing speed may be subject to disqualification for safety reasons.
All cars stopping on a yellow flag will be placed
at the rear of the Restarting line-up. An area will be designated (usually
the pit area) for any work to be done during a yellow flag. Cars
remaining on the racing surface that are able to restart without service will be placed
at the rear, in
the order they were running prior to the yellow flag.
Any car that goes one or more laps
down while in the work area or pit area will be out for that event.
Any Driver who works on his car or permits any other person
(other than a Track Official) to work on his car on the racing surface,
during a yellow flag, shall be penalized to the rear of the field.
If a car needs a second push off, after any cars

SPORTSMANSHIP - Sprint Car racing is a very
emotional sport. As such, good sportsmanship is the key element of any
competitive racing program. This must include respect for all
participants - Drivers, Owners, Pit Crew and Officials. For our part, we
will make every effort to be consistent with our rules regardless of
whom or what is involved. We will treat all participants with respect
and expect similar treatment in return. A Racer's pit area is his castle
- therefore please stay out of other Racer's pit areas, especially after
an incident where you have been involved with that Racer. Drivers -
remember you are responsible for the actions of your crews. Any
offending parties will be fined appropriately and disciplinary actions
will be initiated as deemed necessary.
In the event a URSS Sanctioned Race is rained out
prior to the completion of all Races and Rescheduled for a later
date, the Pill Draw
fee shall be rain-checked for those who have
already paid. At the rescheduled race, all races shall be rerun and al
Drivers will redraw for starting positions. In the event none of the
races have been run and the event is not rescheduled, Pill Draw
pit fees shall be refunded. One lap over half-way through an "A Feature"
shall constitute a complete race in the event a race is stopped due to
bad weather. If a race is stopped by use of the red flag and is ruled
completed, the finishing positions will be paid according to the last
Officially Scored Lap by the Leader previous to the red flag. Any car or
cars red flagged will be put to the rear of the line-up of official

specification (This 3/8inch measurement ensures that the
belly/curl arc is gradual). The belly/curl arc must span
