Division Procedures
1501 Race Line-Up Procedures
All eligible participants will randomly draw a pill to determine the starting order of the heat races. If there are more than 40 eligible participants, additional heat races will be contested for every additional eight entrants. The lowest pill draw will start on the pole for the first heat; the next lowest draw will start on the pole for the second heat, etc. The Chief Steward has the authority to establish the number of heats based on the number of eligible participants.

Each finishing position in each heat race will receive the following points.
1. 55
2. 52
3. 49
4. 46
5. 43
6. 40
7. 37
8. 34
9. 31
10. 28
11. 25
12. 22
In addition each car receives an additional 1 (one) point per car passed. This is based on the difference between starting and finishing position. Starting positions are determined by the "original posted lineup".

Individual point totals following the heat races will be used for feature and other preliminary line up purposes. Ties are broken by the earliest heat or best finish for cars within the same heat.

After the heat races, the top 16 in points will transfer to the feature. The remaining cars will compete in a "Semi Feature" or "Qualifying Mains" to fill the remaining feature positions. A drawing will be held after the final heat race to determine the number of cars that will be inverted for the feature event. The results of the drawing will invert 4, 6 or 8 cars. Depending on the number of eligible participants after all heat races are concluded, the following format will be used to fill the remaining positions in the feature event. All "Qualifying Mains" will line up according to points earned in preliminary heat races.
C-MAIN Cars with accumulated points of 37th place to 54th place followed by the top 2 finishers in the D-Main. Cars finishing first and second will transfer to the B-Main, starting at the rear of the field.

B-MAIN Cars with accumulated points of 17th place to 36th place followed by the top 2 finishers

in the C-Main. The top finishers starting in order of finish will fill the feature.

1502 Qualifications
If qualifications are held, all entries in the race, including post entries, are eligible to participate in a single drawing for qualifying order. This drawing will be closed no later than the start of qualifications. At certain events, cars might qualify in groups using the fastest timed lap in a predetermined period as the official qualifying time. Specifics will be covered in the Entry Form or at the driver's meeting.

1503 Qualification Procedures
All qualifications will be held in accordance with PART VIII in the current USAC Rule Book and the Official Entry for the event with the following additions and exceptions.
1. Any car not able to qualify within three draw positions of its original position in the
qualification draw order may line up at the end of the qualifying order with the
loss of one lap from the qualification attempt.
2. Any replacement(s) or alternate(s) necessary to complete the starting field for a
race will be based upon the posted results of the qualifying race(s) and/or the
fastest official qualification time, or by draw order if no times are posted, and will
be lined up at the rear of the starting field.
3. When the field of cars is insufficient to comprise a complete program, a car
unable to qualify will be able to start last in the first available event. If more than
one such car qualifies for the feature, these cars will be placed at the rear of the
field in the order of their qualifying draw.
4. The Chief Steward is empowered to change the event format, including the
number of laps to be run, as set forth in the Official Entry when unusual
circumstances arise that demand this action.

1504 Stopping on the Course
1. A car that stops for any reason after leaving the grid and impedes the start of the
race will be placed at the rear of the starting field.
2. At certain venues, a two-spin/stop rule will be in effect. When this rule is in effect
and in case of a spin and/or stop, only one assisted restart per race, per car will
be permitted. Additional restarts will be at the discretion of the Chief Steward.
1505 Pushing
1. Push starts at any time are subject to the availability of authorized push vehicles
and at the discretion of the Chief Steward.
2. Cars stalled on the course may be pushed to start providing the engine is running
before arriving at the pit entrance.
1506 Laps Under Yellow Flag
1. In events of 60 laps or less, laps where the yellow flag is displayed will not be
scored.
2. Yellow flag laps for indoor races on 1/10 mile tracks or shorter will not be
counted.
3. If the yellow flag is displayed before the field completes the first lap, a complete,
two abreast restart will be made with the exception that any cars not completing
the first lap, or stopping, will be placed at the rear of the field.
4. If a second restart is required, the cars will line up single file with the exception
that any cars not completing the first lap, or stopping, will be placed at the rear of
the field.
5. If the field completes the first lap under green, the first lap shall be scored. Any
subsequent yellow flags will result in a single file restart lineup. This lineup will be
determined by the last completed lap scored under the green flag.
6. Any car not completing the lap in which the yellow was first displayed, shall be
considered involved in the incident and placed at the rear of the field.
7. If an incident occurs on the first lap where the yellow is displayed, and after
running laps under yellow it becomes necessary to display the red flag, the
restart lineup will be based on the yellow flag procedure and cars involved must
start at the rear of the field.
8. A car unable to start a race that is later red flagged can enter the restart lineup at
the rear of the field.
9. During a caution period, a car may be called into the "designated pit area", using
the Black Flag, for inspection by the Officials. If the car is determined to be safe
to resume racing, and no work of any kind is performed, it may return to its
pervious position.

1507 Hazardous Mechanical Conditions
All cars must have nerf bars, rear bumper, hood and air cleaners in order to start or continue in a competition.

1507 Repositioning
Any driver who improves his or her position during a start or restart by passing other cars before a designated point on the track shall be guilty of a violation. The penalty will be a repositioning of the car rearward two positions for each car passed. This penalty will be assessed at the next yellow caution period if possible or in the Official Finish of the race.

1508 Motorized Support Vehicles  are required to have a plainly visible number on the front and back of the vehicle corresponding to the racecar number.

1509 Engine Protests
The fee for protesting a USAC Ford Focus engine is $250.00. This fee is for inspections that are not routinely performed by the Technical Director. Specifics of this protest procedure including eligible Protestants and penalties are available from the Chief Steward.
