No Provisional starting positions will be awarded in the Feature. Only exception is when field is 21 or 22 cars and those cars may be tagged onto the back of the Feature.

2017 URSS Season Points

URSS Regions will consist of Colorado and Kansas Regions.

Regional Points Championships

 Will be determined by counting 80% of all regional races completed within your region. Example: if 40 races are completed, your best 32 races will be used.


National Championship

All National races designated as National (N) will count towards the National Championship.

(NOTE) Separate point averages will be used for National and Regional Series races. All National Races will use only point averages accrued during National Races. Regional race point averages will include all races run.

Tiebreaker Rule

In the case of a tie for the National Champion or the Regional Champion, the Champion will be determined by the Driver who won the most Features.  Tiebreaker #2 will be the Driver with the highest point average.


1.   All Heat Races will be lined up according to Pill Draw.  All "Registered URSS Drivers" will pay a $20.00 Pill Draw fee with all monies going towards the year end Points Fund. 

2.   Points will be awarded in Heats with Passing Points ( 2 points per car passed + finish points based on the table below.)

3.   Top Ten on Total Heat Race Points will Automatically transfer to the "A" Main.

4.   Top Eight Qualifiers will be inverted for the "A Main" according to your Point Average for completed features. Cars qualifying  9th and 10th will start 9th and 10th. Any drivers without a point average will be given 155 as a point average. First "A Main" feature of the season will be lined up according to heat race passing points and the field will be inverted. If any race has a field where over 50% of the Drivers have no point average, the feature will be lined up according to heat race passing points. Average points will NOT include DNF’s.

5.   Last Chance Race will be lined up "Heads Up" according to their Heat Race Points accrued. In the event of no Last Chance Race, the rest of the field will be lined up according to their Heat Race Points.

6.   Top Ten in Last Chance Race will advance to the "A" Feature and will line up in the order they finished behind the Top Ten already transferred.

7.   Cars with No Point Average that Qualify for the "A Main" through their Heat will start behind all Pre-Qualified Cars with a point average.

8.   In the event of a tie for Tenth in Qualifying Points, the Driver earning the most Passing Points will be considered the Qualifying Driver. If a tie is still present, the Driver who earned the Points first shall be considered the Qualifying Driver.

9.   Passing Points will be figured on the "Actual Starting Position" on the Final Parade Lap.

10.  Any Car missing four consecutive "Races" of URSS Sanctioned Events will forfeit their Point Average the First "Race" upon returning. You will resume your Total Season Point Average the following Race or Weekend. Note: this rule will not apply to those who have run at least 50% of all URSS sanctioned races in any URSS region.

11.  Any Driver failing to draw for the Heat Races or Pack Race Surface (when requested) will not receive Passing Points, but only the Points accumulated through their finishing position in the Heat Race. During packing, cars that are not assisting in rolling in and packing problem areas on the racing surface will also lose passing points during their Heat.

12.  All cars must be in push off lane or being pushed toward it when the first car is pushed off to start any event.  (Heat or Feature) Cars not in the push off lane or at least heading to it will be put in rear of the field.  

Passing Point Schedule






1 car @ 2 = 2 pts



2 cars @ 2 = 4 pts



3 cars @ 2 = 6 pts



4 cars @ 2 = 8 pts



5 cars @ 2 = 10 pts



6 cars @ 2 = 12 pts



7 cars @ 2 = 14 pts



8 cars @ 2 = 16 pts



9 cars @ 2 = 18 pts



10 cars @ 2 = 20 pts

13.  A Car and Driver qualify as a Team. Each Driver can qualify only one car. No Driver may be permitted to change cars after taking the Green Flag of his Qualifying Heat Race. An exception to this rule will be on a two-day race. 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. In the event a car drops out of the line-up for mechanical reasons, the balance of the field shall move straight forward. 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. In the event a Pace Car is not used, the Pole Car will set the pace, which shall be consistent with track conditions and as required to keep the field in formation. Do not pass the Pace Car. 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. 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 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. If there is no flag after the penalty then it will be enforced at the end of the race.

18.  Any car requiring a second push on start or restart of race will be placed at rear.

19.  On all single file restarts after one lap, the restarts will start at a Cone to be placed on the Front Straightaway. The leader must start race at or near the Cone and all cars must go outside of cone in the proper aligned order. Leader must set a consistent pace.

Any car going inside of, hitting cone or passing a car prior to going outside cone will be penalized two spots per Car passed. If no Yellow appears before the Checkered Flag, you will be penalized two (2) spots for each position passed at the finish.

20.  Any car on or near the racing surface that delays the start or restart of any race shall be penalized one lap by Officials. A work area will be designated at the Driver's Meeting.

21.  Alternates may be taken to fill any vacancies that occur, but only prior the initial Green Flag.

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 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 car have started, he will restart at the rear of that race.

Any car that is involved in two 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.


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)

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 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, 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.
