Drivers may be replaced due to illness or injury by any Driver not already taking a Qualifying Green Flag, but will be placed at the rear of the field.

14.  The URSS or their representative will advise Drivers of the make-up of the number of Heat Races, Main Events, field Maximum size and other pertinent at the Drivers Meeting.

15.  The lineup posted on the Pit Bulletin Board when cars enter the racing surface for any race shall be the final lineup.

The exception being if 2 cars drop out from the same row, prior to the Green Flag.

16.  The Start will be official only upon the Starter signaling with the Green Flag. In the event a Pace Car is used, all cars shall take their proper position behind it.

URSS shall be empowered to disqualify or penalize any Driver violating this rule.

17.  A White Line or Cone will be placed on the Turn 4 area for all double file starts. All cars must remain in proper order until the lead car or cars reach this point.

Any further violation will result in the offender to be placed a row back with the car behind the offender being brought to the front row.  Any other car not in proper position in Official's judgment will be penalized a minimum of 2 positions plus one position gained over one.  This penalty will be imposed on the next Yellow or Red flag.

22.  Any car not running at a reasonable racing speed may be subject to disqualification for safety reasons.

FLAG PROCEDURES:

YELLOW FLAG:

All cars stopping on a yellow flag will be placed on the rear of 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 on 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 have started, they will restart at the rear of that race.

Any car that is involved in two unassisted yellow flags will be disqualified for that event.

There will be one attempt at a Green-White-Checkered Flag, if another yellow flag appears then the race will be restarted with the Green and White displayed at the same time.

RED FLAG:

Cars that the Red Flag was thrown for and any other cars that change any tire will be placed at the rear of the restarting line-up. All others will get the position they were running in prior to Flag, if ready to join restarting line-up when called provided they went to red flag work area.

It shall be the decision of the Flagman and URSS Officials as to what cars the flag were displayed for, and their decision is final.

All Restarting line-ups will be single file after one lap with any lapped cars being placed in line-up.

Note: Any car changing any tire during a red flag will be placed at the rear also. (Wheel spacers may be changed if monitored by Track Officials.)

A race is not considered complete until the checkered flag appears. If a yellow or red flag must be thrown after the checkered flag appears, the race is officially over and the payoff will be done in the same manner as a yellow or red flag realignment.

PROTEST FEES (Figures in Parenthesis Are Filling Fees)

1.   Motor tear down (heads off) and cylinders inspected: $500  ($100)

2.   P & G  Fuel Test  $500  ($100)

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.

RAIN OUTS

In the events 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 fees and 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 finish.
