  RACE PROCEDURE:

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

Each registered car will carry an identification number as assigned by track personnel. It shall be sufficient in size so as to be readily identified by officials and spectators. It shall be positioned on both sides, the top and the back of the automobile, also the front. The number must be of a contrasting color to the general paint scheme of the car so that it is readable under all conditions of light and speed.

The track owner-promoter and the officials will not be responsible for allowing a late entry to compete.

Any driver not ready to compete when called will be sent to the rear of the starting line-up.

Once a race is started on a preliminary line-up lap, relines will be single file

A race may be stopped at the discretion of starters 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 flags for the purpose of signaling the competitors.

No race is official until the officials make the declaration of final scoring of positions in all events.

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.

A dead heat may or may not be re-run at the discretion of the referee. If the dead heat is not re-run the prize money and points for both positions under contention shall be divided equally by participants.

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

  POINTS:

All Classes - 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 a "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 receives five show-up points.

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.)

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

  LINE-UP PROCEDURES:

First night, all drivers draw for heats. Qualifiers redraw for starting positions. One heat - 5 redraw; two or five heats - 10 redraw; three, four or six heats - 12 redraw.

From second night on, heat races are lined up by season point average, stagger inverted, lowest point average to front, highest point average to rear. New drivers carrying no point average start on the tail. Point averages are figured from I.M.C.A. point system. Average is figured by driver's track point total divided by the number of times he/she has competed at track.

"B" mains are lined up straight up from the heats with the highest finishing non-qualifiers to the front.

When one heat race is run, top five qualifiers will be inverted for feature lineup according to season point average. When two or five heat races are run, the top 10 qualifiers will be inverted for feature lineup according to season 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.

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

If a driver is absent for two consecutive events (excluding rain-outs), upon his/her return shall be treated as a new car (rule #5) for the first week he/she returns.

There are no double feature nights allowed, excluding rain-out make-up features. A program is not considered a rain-out unless qualifying races have been completed.

For each car less than 10 entries for that event, one point fewer than normal shall be awarded for feature finish. (Example - nine cars, 39 points to win; eight cars, 38 points to win, etc.)

Track option to line up mid-season and season championships straight up by total points.
