Green Flag (Start of Race) At the beginning of the race, when the starter gives the green flag, karts must maintain position as designated by MCS Officials until they have crossed the starting line. On restarts, all passing will be to the right until after passing the starting line.
Blue Flag with Diagonal Yellow Stripe (Passing Flag) The blue flag with a diagonal yellow stripe signifies that faster traffic is overtaking the karts being signaled. Karts being given this flag must prepare to yield to overtaking traffic and give 1 full lane to allow safe passage of karts racing for position.
Yellow Flag (Caution) A. The yellow flag signifies caution and this flag will be given by the flagman immediately following the occurrence of the cause for caution. When the yellow flag is displayed, all karts, regardless of their location on the track, will slow down and maintain position with respect to other karts. Restart order will be determined by the last green lap scored and karts causing caution incident will line up at the rear of the field. The MCS Officials have complete discretion to determine the positions of the karts at the time the yellow flag was displayed and to reposition the karts in accordance with their determination. B. Karts must slow down to a cautious pace on all yellow flags. C. In the event a caution kart is used, no kart may pass the caution kart unless directed to do so by an Official. Any karts illegally passing the caution kart will be penalized. D. The starter will signify one (1) lap before the green flag will again be displayed. E. Pit attendants and mechanics shall not go on the race track for any reason, while the karts are racing, or while they are running under the yellow flag. The only time drivers or karts may receive such services is when they are completely stopped and off and outside the race track. F. No pit crews may service or repair any wrecked or damaged kart until the kart has been removed from the racetrack and safely removed from race track.
Red Flag (Race Stop) A. The red flag means that the race must be stopped immediately regardless of the position of the karts on the track. The red flag shall be used if, in the opinion of MCS Officials, the track is unsafe to continue the race. Karts should be brought to a stop in an area designated by MCS Officials. No repairs or service of any nature will be permitted on any kart on the racetrack. B. Drivers are to stay in their karts at all times unless directed otherwise.
Black Flag (Leave Race Track Immediately) A. A black flag means to immediately exit race track and report to the MCS Official at the tech shed. It does not mean automatic disqualification. At the discretion of the MCS Officials, if the driver does not obey the black flag directive, the driver may then be given the black flag with a white cross to inform the driver that scoring of his or her kart has been discontinued until further notice.

When the lead kart has completed the required race distance, the race will be declared “official” regardless of flag being displayed. B. When the checkered flag is given to the leader, the balance of the field receives the checkered flag in the same lap. Finishing positions will be scored according to most laps traveled, whether the kart is still running or not. C. The driver receiving the checkered flag first in any feature race must bring his/her kart to the starting line or designated area and remain there until released by MCS Officials. Race Track Lights A. When the red light is displayed, it means all movement on the track is to cease. B. When the yellow light is displayed, it means caution is in effect.
The kart must start the feature event to receive points for that race. The registered driver of the kart will earn points, no switching of drivers or switching of karts during the night of racing will be permitted, i.e.; the registered driver must race the heats and feature in the same kart, the driver cannot race a kart in the heat and switch to another kart in the feature event. Please discuss any concerns with the Race Director.
The break down for points are as follows:
10 points awarded per position for each kart in that class. (Example: 7 karts in the class 1st place will receive 70 points, 2nd place will receive 60 points, 3rd place will receive 50 points, 4th place will receive 40 points, etc.)
Same points rule applies to the 2nd heat race as the first.
Heat race points DO NOT count towards your points total. They are for the sole purpose of determining your starting position in the feature.
In case of a tie in points in the heat races to determine the starting positions for the feature race, the winner or higher point earner in the 1st heat race will be given the more forward starting position.
1st place-200 points plus the number of entries in the class. (Example: 200 points + 10 karts in class=210 points)
2nd place – 175 points plus the # of entries
3rd place – 155 points plus the # of entries
4th place – 140 points plus the # of entries
5th place – 130 points plus the # of entries
6th place – 120 points plus the # of entries
7th place – 110 points plus the # of entries
8th place – 100 points plus the # of entries
9th place – 90 points plus the # of entries
10th place – 80 points plus the # of entries
11th place – 75 points plus the # of entries
12th place – 70 points plus the # of entries
13th place – 65 points plus the # of entries
14th place – 60 points plus the # of entries
15th place – 55 points plus the # of entries]
