G. Start of Race:

                1. One the pace laps have begun, any car entering the pits and re-entering the race surface, before the green flag, will be considered to have made a pit stop and must start at the rear of          the field.
                2. Any car that wants to re-enter the surface after the green flag has waved must obey the track officials at the end of pit road. The Blend Rule is in effect at all times when entering the surface from the pit area. (See No. 8 below.)
                3. The flagman, and only the flagman, will start the race.


H. The Cone Rule:
                1. The Cone Rule is in effect during all restarts during a race. A cone will be placed on the start/finish with two (2) laps reaming under caution. Drivers will then be able to choose the inside or outside lane. Cars may NOT change lanes after they have passed the cone.
                2. The Cone Rule is only used after one (1) lap has been completed and scored in a race.


I. Restart:
                1. The lead car will restart the race as soon as they have entered the restart zone in
                Turn 4.
                2. All restarts will be double-file due to the Cone Rule.
                3. There will be two (2) attempts at a double-file restart. If the two attempts at a double-file restart are unsuccessful, due to jumping the start or an accident, cars will be lined up single-file.          
4. If the same car jumps the start or restart twice, they will be placed at the rear of the field. If there are cars one or more laps down, the car will be      placed as last car on the lead lap.

                2. Any car that causes a caution will go to the rear of the field. If you are on the lead lap, you will be placed as last car on the lead lap. If you are one or more laps down, you will be at the tail end of the field.


K. Caution Laps:
                1. Caution laps do not count on weekly shows, only green flag. Officials will alert drivers if caution laps are going to count as part of a “special event.”
                2. Cars will run under caution for as long as it takes to clear the track of debris, make the track    safe and set the correct line-up.
                3. Once the track is safe to return to racing, cars will be given “two to go” and set the double-file restart per the Cone Rule. (Refer to restart procedures to determine the restart.
                4. All cars re-entering the racing surface after a pit stop must re-enter the racing surface at their designated area. A stop-and-go official will direct when it is safe to re-enter the racing surface. Any car that re-enters the surface other than the area described, will be immediately black flagged and brought down the pits for a stop-and-go penalty.


L. How you are determined to be in or involved in a caution:
                1. If you cause a car to spin, being it on purpose or accident, you will be deemed as at fault and placed at the rear of field according to Speedway rules.
                2. If you make contact with cars or come to a stop, you are deemed as part of that caution and will be placed at the rear of the field according to Speedway rules. If you continue to move, you are not part of the caution, unless you are the initial cause. 
                *Thinking before you act, is the best way to avoid causing or being in a caution.


M. Warnings:

                1. A warning will be a rolled up yellow or black flag pointed at a driver during a race or caution period. A warning will mean that Speedway officials have deemed an action by you as inappropriate. A second warning will result in the Chief Pit Steward directing you to the side and issue a verbal warning. If an initial warning and two additional verbal warnings are given and a driver continues inappropriate behavior, the driver will be parked for the remainder of the event.


N. Blending off of Pit Road:
                1. Upon re-entering the track from pit road, the driver will be instructed by an official when they can “go.” When re-entering, stay to the bottom of the track (apron) until they have exited Turn 2 and are entering the backstretch.
                2. Any blending or moving up into traffic before the exit of Turn 2 will result in the driver being black flagged and serving a stop-and-go penalty.

                *This is NOT a Blend Rule that applies during a caution or spin. It applies only when re-entering the track from the pit area. If you are involved in a caution, including a spin, you will be placed at the rear of the field per Speedway rules.
