 SECTION IV.  RACE PROCEDURE

The following procedures are UMP WEST recommended, but not mandatory.  A promoter or track may use different procedures if better suited for their personnel, racers, track, etc.  Tracks must notify the UMP WESTof variations to procedure.

1.  The number of cars starting a race shall be determined by the track officials and shall be determined by the type of the event, the width, length and condition of the track. 

2.  Any driver not ready to compete when called may be sent to the rear of the starting line‑up. 

3.  Cars requiring pushing to get started, either in staging or during a race on the track, will start scratch or go to the back of the pack.  After entering the track, if re-entry is allowed under yellow, any car leaving the track for any reason must tag the back. 

4.  Once a race is started on a preliminary line‑up lap, repositioning of cars not in position shall be at the discretion of officials. 

5.  A race may be stopped at the discretion of starters (flag personnel) or other officials at any time they consider it dangerous to continue, but only an official has the right to stop a race and no driver, car owner, pit man or mechanic may use the starter's f1ags for the purpose of signaling the competitors. 

6.  Restarts after one completed lap will be single file, nose to tail, in-line, no passing until the cone is passed.  A cone will be placed on the back straight or the best area at each track.  Drivers passing before the cone will be scored two positions back per incident. 

7.  No car is to receive assistance after the white flag is displayed and all finishes must be made under the car's own power or momentum. 

8.  No person shall be allowed on the track during a race except the starter and race officials. 

9.  Cars involved in a wreck go to the back.  “Involved” is defined as follows:  Any car making contact and/or stopping on the track, and a car that was the “cause of the yellow” whether or not that car stops.  Cars making minimal contact while trying to avoid the wreck, which do not stop on the track, will not be considered involved.  If two cars have inadvertent close contact and one car spins, the spun car will go to the back.  In multi-car pile ups, all cars involved go to the back.

10.  Modified class does not race to the yellow.  Line-up reverts back to the last completed lap. 

11.  Any car charged with causing two yellow flags will be black flagged from the race. 

12.  Promoters may request variance from individual race procedures in writing.   Requests, if approved, will be granted in writing and published to members.

SECTION V.  POINTS

1.  Weekly "A" Feature win is 40 points, with each subsequent position worth one point less.  This makes the 24th spot in the feature worth 17 points.  Should any track start more than 24 cars in the feature, all positions from 24th on back receive 17 points.  When a track runs "B" feature(s), the first non‑transferring driver receives 16 points and each subsequent position, back to sixth spot, receives one less point per position.  Sixth and each position on back in the "B‑ feature(s) receives 11 points.  This applies to all "B" features, if more than one are run per night.  Any driver not qualifying for an "A" or "B" feature (by the fact of not having run a heat race) receives five show‑up points. 

2.  Should a driver qualify for a "B" feature or the "A" feature and not be able to make the field due to mechanical or other difficulties, driver will be scored in last position of the race qualified for, and receive points accordingly.  (It is up to the track whether his vacated position will be filled in the feature by the next qualified driver.)

3.  A driver black flagged for mechanical failure will be scored in the appropriate position for payout and points, based on when they left the track.  The same rule applies for a car black flagged for causing two yellows. 

4.  The driver is qualified and receives points, not the car.  No car changes will be made at any time without previous notification of officials.  All changes must be made in the pits only, at the discretion of officials.  The driver will then line up in the scratch position.[SL1]   Any driver wishing to change cars must be qualified to compete in the race for which he/she is changing cars, and must start that race at the rear of the field.  Once a driver has changed to another car, he/she must finish the program in that car.  Driver may change to any UMP WEST legal car.  If a driver gives up his car for another driver to use, the first driver cannot race that car the rest of the night.

5.  A disqualified driver will not receive points or money for the night and is not counted as having been in attendance for the night.  Rough driving, unsportsmanlike conduct, and failure to tear down for inspection are some of the reasons for disqualification. 

6.  If there are less than 20 entries, for each car less, one point fewer than normal is awarded for feature finish (i.e. nineteen cars, 39 points for win; eighteen cars, 38 points, etc.). 

7.  Ties at series end:  Should two or more drivers have the same point totals at series end, the number of weekly sanctioned feature wins will be the tie‑breaker, then second‑place finishes, etc. 

8.  There are no double feature nights or double point nights allowed.  A program is not considered a rain‑out unless heat races have been completed.  Anyone in attendance at a rained out race will receive 5 show-up points.  Races that are cancelled completely receive no points at all.

SECTION VI.  LINE‑UP PROCEDURES

1.  First night, all drivers draw for heats.  Qualifiers may redraw for starting positions OR line up heads up by heat finish; method of line up for qualifiers must be announced at pit meeting.  One heat ‑ 5 redraw; two or five heats ‑ 10 redraw; three, four or six heats ‑ 12 redraw. 

2a.  From second night on, heat races are lined up by track season point average, stagger inverted, lowest point average to front, highest point average to rear.  For example, in filling three heat races: 

Car 1 is the Lowest Points Average Car and is pole in Heat 1

            Car 2 the Next Points Average Car is pole in Heat 2

            Car 3 is pole in Heat 3

            Car 4 is 1st row outside Heat 1

            Car 5 is 1st row outside Heat 2

            Car 6 is 1st row outside Heat 3, etc. 

New drivers carrying no point average start at the tail.  (Should there be two or more drivers with no average or same point average, then a drawing should be held between those drivers for their lineup position.)  Average is figured by driver's track point total divided by the number of times he/she has competed at track. 

2b.  Once a driver has started a heat race (green flag) they will be scored in that heat.  Driver may not switch heat races once they have started in a heat race.  If you have a flat, wreck or mechanical failure, you must take whatever place that puts you in for the next qualifying race or A main.  If a driver has not started a heat race and has a mechanical problem, they may switch to the last heat race and start scratch.  The same rule would apply for multiple B mains.  If you cannot start your B main you can move to the last B main, scratch. 

3.  "B" mains will line-up straight up from the heats with the highest finishing non‑qualifiers to the front. 

4.  When one heat race is run, top five qualifiers will be inverted for feature lineup according to track season point average.  When two or five heat races are run, the top 10 qualifiers will be inverted for feature lineup according to season track point average.  When three, four or six heats are run, the top 12 qualifiers will be inverted for feature according to season point average.  Remainder of “A" feature is lined up straight up from heats and/or B features. 

5.  A driver that qualifies but does not have a point average shall be lined up in the last invert position. 

6.  If a driver is absent for two consecutive events (excluding rainouts), upon his/her return shall be treated as a new car (rule #5) for the first week he/she returns.  A driver who had been DQ’d for the night is treated as if he had not shown up for that night and the night is not counted towards their points average. 

7.  Drivers switching cars may do so as described in Section V, Para.  4, however, they will line up in scratch position. 

9.  Tracks have the option to run special races through the year with special line up procedures if requested in advance and approved by UMP WEST.

10.  Track may have one program, other than opening night, where a draw‑redraw system may be used for line up.  Claim at these races will be same as opening night.

SECTION VII.  ENGINE CLAIMING RULES

3.  First place finisher must report directly to claim area and is subject to engine claim by any other driver in feature that has not been lapped.  Failure to report directly to claim area will result in disqualification and loss of money and points for first infraction (engine is still claimable).  Driver allowed one claim ONLY per event, regardless of outcome of that claim.  In case of multiple claims on same engine, a drawing will be held to determine which driver gets the swap.  Should the first eligible driver withdraw his claim, the next qualified driver will be allowed the engine swap. 

4.  Driver making claim must drive his race car immediately after finish of feature, under its own power, directly to claiming area.  It is highly recommended that only involved drivers and officials be allowed in claiming area. 

5.  Claims must be made to the track or UMP WEST official immediately after end of feature race, and swapped engines must be completely removed within one hour from time claim is made and driver agrees to swap. 

6.  Claims must be made to the track or UMP WEST official, and $500 cash must accompany declaration of intention to claim. 

7.  Only driver may claim engine and only driver may agree to sell or refuse to sell engine. 

8.  Refusal to sell forfeits all cash and contingency winnings for feature.  Any driver refusing to sell engine loses points and monies for that night and must pay $500 to UMP WEST for track modified points fund before they can race again.  His or her winnings will also go into the track modified points fund. 

9.  Once an engine claim has been made and accepted, the engines are not to be started, under any circumstances.  The cars are to be pushed to the area where removal will take place.  Any driver starting a claimed engine will be immediately disqualified from that event and will be suspended from all UMP WEST events until a $500 fine is paid.  All claimed engines must be removed from cars at the track. 

10.  The cylinder block may not be altered in such a way as to prevent it from being used in a stock application.  Stock approved OEM components must be able to be immediately used in their stock location.  Any sabotage discovered to a claimed engine will result in driver being suspended from competition for 30 calendar days and until $1,000 cash fine is paid to UMP WEST.  Drivers are to be held accountable for any sabotage discovered while pulling the engine, and will be responsible for any and all penalties as a result of any sabotage.  The claim will be disallowed and the money returned to the claimer. 

11.  No driver may claim more than two engines during current calendar year. 

12.  Claim is in effect on opening night for all eligible drivers and driver must have been at track on opening night to be eligible to claim second night of season.  Following that, no driver may claim unless he/she has competed at that track the two previous consecutive events. 

13.  No one driver may claim any other one driver more than once during current calendar year. 

14.  A disqualification will not affect a legal claim.  The engine will be pulled and transferred prior to any penalties being assessed.
