The rules and specifications in this guide are intended to make all Midwest Motorsports sanctioned events a safe, fun, and fair experience.

Rules Knowledge: Everyone who registers for a Midwest Motorsports sanctioned event as a kart owner or driver and all individuals who enter the pit area or racing surface during a  sanctioned event are required to know these rules and any supplementary rules or instructions concerning the event and must abide by them.

Responsibilities: The kart owner and or driver is responsible for the safe condition and operation of any kart at race events. The track owner is responsible for providing a properly maintained and safe place for the event.

Spirit and Intent: This manual provides technical specifications and inspection procedures to establish the legality of engines, racing chassis, and associated components used in Midwest Motorsports  sanctioned events. Officials at Midwest Motorsports events are authorized to decide of any change or design is an attempt to “beat the rules.” Also, just because a technical specification or part is not described in this manual does not imply or guarantee its legality. In these cases, the race officials will disqualify an entry, and the Midwest Motorsports will uphold the disqualification based on the “spirit and intent” of these rules. “Just because this Technical Manual does not state that you cannot, do not assume that you can.” While these rules are intended to be a guide for technical inspectors, they will also provide guidelines for Midwest Motorsports members in preparing legal engines and entries.

Class Entry Fees: Entry fee’s vary by class.  Please look on website for all entry fee’s.  NO checks will be accepted at track.

Pit Pass:  Pit passes will vary per event.  NO checks will be accepted at track.


General: Drivers must be in good standing to enter Midwest Motorsports sanctioned events. Drivers must abide by any age restrictions in any given class.

Driving Ability: Race director has the right to refuse any junior driver from participating in a Midwest Motorsports event based on his or her driving ability.

 Competitor Age Requirements: All Midwest Motorsports classes have a minimum “competition age” requirement for drivers; some classes also have a maximum age limit. Both limits are stated in the class descriptions.

Competition Age: A driver’s actual age as of December 31 shall establish his/her “competition age” for the next calendar year. EXAMPLE: A Driver is competing in a class that has a maximum age of 15 years. If the driver is 15 on December 31, 2013, the driver may compete in that class for the entire 2014 calendar year, no matter when the sixteenth birthday occurs.

Advancing in Age Category: Drivers who are in the “option year” may compete in the lower age class for the entire calendar year; however, if a driver moves up an age class, he may not compete at the lower age at any Midwest Motorsports events for the remainder of that year. EXAMPLE: Driver is 12 at the beginning of the 2014 season but turns 13 during the 2014 calendar year. He may race either in Junior 2 or Junior 3 classes. If the driver chooses to move up to Junior 3 at a Midwest Motorsports event, he may not return to Junior 2 status.

 Attained Age: Any driver that is racing the Junior 1 class must be the actual age of 7 years. This is the attained age of the driver. Any driver who is moving up to adult classes must be the attained age of 15.

Attempting to Falsify Documents: Falsification of any competitor’s age or any other information required on the membership application form will subject that member to disqualification and suspension of membership privileges. Family Members are entirely responsible for supplying accurate information for the Minor Members.

Driver’s Physical Condition: The Race Director may refuse to allow a driver to race based on the driver’s physical condition or advice from track medical personnel or from a hospital or other medical facility.

Disabled Drivers: Drivers with disabilities wishing to compete in Midwest Motorsports events may apply in writing for the waiver of a specific rule or specification. The request may not negatively affect safety and may not provide a significant performance enhancement.


Practice: A competitor must be entered in at least one class before going onto the track for official practice, qualifying, or racing. Failure to do so may result in disqualification for that event and possible suspension. You are allowed to practice only with the classes that you are entered in for racing.  If you are caught practicing in any class you are not entered to race in you will be penalized.

Official Entry: The official entry at all Midwest Motorsports events includes the driver, kart frame, and engine. Once the kart passes through scoring on an official lap, the kart frame and engine cannot be changed without permission of the Race Director. If an approved change is made, the entrant will be subject to tech of all engines and/or chassis used during the heat or feature races.

 Relief Driver: No relief driver will be allowed at any event.

Payment of Entry: Failure to properly pay registration, entry, an/or pit pass fees, including uncollectible checks or cancelled credit card transactions, may submit individual to disqualification from the Midwest Motorsports event and possible suspension of membership privileges. No points will be given to any entry that has not been paid in full.


Behavior: All drivers shall conduct themselves in a safe and orderly manner. Physical violence or abuse of any individual, official, participant, or spectator at the site of an event will subject the offender to immediate disqualification, ejection from the event site and possible suspension of membership status. The Race Director must report such incidents to the race promoter within 24 hours of the event’s conclusion with the recommendation for disciplinary action.

Verbal Abuse: Any verbal abuse will be subject to unsportsmanlike conduct penalties. This rule applies to any person on track property. Verbal abuse to any official or partner of Midwest Motorsports at any time by a member will result in possible suspension or termination of membership.

Banned Substances: No alcohol is allowed in the pit area during a Midwest Motorsports event. Local track rules will dictate whether alcohol may be consumed on the track property after an event. No driver shall be under the influence of any medication that may interfere with the driver’s ability to operate a racing vehicle in a safe manner.

Pit Crew: Pit crew and family members are the responsibility of the drivers. Any unsportsmanlike conduct by a crew member or family member will result in action being taken against the driver.

Pit Area: All persons entering the restricted area of a Midwest Motorsports event site must sign all insurance-related documents as prescribed for that event. Failure to do so will subject the individual to disqualification, immediate removal from the restricted area and/or suspension of membership privileges.

Drivers’ Meeting: All drivers must attend drivers’ meetings. If you are caught not attending meeting you will be penalized by qualifying first in all of your entered classes for the weekend.  Drivers will also be docked 10 drivers points if they are caught not attending a required drivers meeting.  Roll call may be taken so don’t miss a meeting.  NO EXCEPTIONS OR EXCUSES!!!

Transponder Scoring: Where transponders are used, it is the driver’s responsibility to ensure that the transponder is securely and correctly mounted and functioning before entering the track for qualifying or racing. Failure of the electronic scoring system to pick up the transponder signal may prevent the competitor from being timed for qualifying or scored in the event; however, if a transponder fails to function during a race, the Race Director shall contact the finishers immediately in front of and immediately behind the non-scoring kart and consult with the other race officials to be sure of its finishing position. If the position can be confirmed, the Race Director can award the non-scored kart its correct position.  Transponders are to be placed on the left nerf bar on the front bar.  If they are found to be in another location of the gokart you will be subject to loosing your scoring position.  It is the racers responsibility to make sure that the transponder is placed in the correct position.    NOTE: In the event a race facility does not have a transponder system, manual scoring will occur.


Course Boundaries: Course boundaries such as discs, pylons, or other markings designated by the Race Director must be observed by all drivers at all times. Practice pylons are used to help prepare the track for optimum racing conditions. Any driver hitting a pylon during a practice session will be black flagged from that round of practice and must immediately leave the racing surface.

Stopping on the Racing Surface: If a driver is forced to stop on the racing surface during practice or a race, the competitor must raise both hands to signal approaching drivers that he or she is immobile. The driver is also responsible for moving the kart to a safe area as quickly and safely as possible.

 Re-Entry to Track: There will be no re-entry once the green flag has dropped. If a competitor leaves the track, he or she will be scored in accordance with the number of laps completed.

Slowing Down on the Racing Surface: When a kart slows from racing speed on course, the driver must signal to approaching competitors by raising a hand high enough to be clearly visible from behind. This requirement includes slowing to enter a pit entrance lane during practice, heats or racing.

Unsafe Driving: Unsportsmanlike driving will be determined by the race officials. Bumping or erratic driving such as blocking or pushing should be avoided. If, in the judgment of the race officials, a competitor shows unsportsmanlike driving, he or she may be disqualified and is subject to further penalties. Unsafe driving will be the sole call of the Race Director and Head Flagman. Competitors who are deemed to be driving in an unsafe manner will be black flagged and must leave the racing surface in a safe and courteous manner.

Lapped Karts: Participants about to be lapped by faster competitors are responsible for knowing of the approaching faster karts and must move out of the racing line until the end of the race. Lapped competitors will observe the black flag and must move to top of racetrack and exit track as soon and safely as possible.

Initial Start of Race: Double file initial start. Front 2 karts must be within an acceptable distance of each other (preferably side by side). Start will be determined by the Flagman and/or Race Director. If after 2 attempts (or fewer, if Race Director sees fit), drivers cannot achieve a fair start, field will be lined up single file and started.

 Exiting the Track: At the completion of any race session all karts exiting the track must proceed to the area designated by the Race Director or they will be ineligible for points and/or awards. All karts must cross scales. NO DRIVING IN THE PITS! This will be cause for immediate disqualification.

 Accidents: Race officials will, at their discretion, inspect all karts involved in an accident. Officials may also inspect all safety apparel after such an incident.

 Crew Members: Pit crew and family members are not permitted on the track at any time the track is active. The only exception to this rule is if the Race Director or other race official directs non-drivers to the track. If your pit crew or family member enters the race track without permission then you will be black flagged from the race.

Injured Driver: If a driver involved in an accident appears to be injured, the Race Director may refuse to allow the driver to continue to race. If the Race Director decides that unsafe or unsportsmanlike driving caused the red flag, the offending driver(s) will be placed at the back of restart order. The Race Director may disqualify the offender(s) if he deems the infraction to be serious enough to warrant. The Race Director may also take disciplinary action.

Accident Weigh-In Procedure: If the medical personnel on site state that a driver needs to be transported due to an accident, the driver will receive finish position points regardless of whether he/she is able to weigh-in or not. If the medical personnel keep a driver for examination, the Race Director may waive the weigh-in requirement if the driver’s class has already cleared the scale.

 Kart Repairs: If a race if red-flagged for any reason NO repairs or touching of go-karts is permitted.  If a race is stopped under a yellow flag then you must be in your restart position and will be allowed to make minor repairs to your go kart with permission or assistance from a track official only.  NO ONE from your pit crew is allowed to enter the race track without permission from track officials.  If your pit crew enters the race track without permission then you will be black flagged from the race.  A complete restart occurs when the field has not completed a full lap under green. The Race Director may disqualify a damaged kart for safety reasons.

Race Restarts: Restarts after a yellow or red flag will revert to the most current order of last completed lap. If no laps have been completed, the field will revert to lineup order. Karts involved in the incident causing the delay will be put to the rear of the field at the Race Director’s or Head Flagman’s direction.  If you spin to avoid an accident then you will be placed back in your original position prior to the caution.  A lap is considered to be complete when all karts on the lead lap have passed the finish line or scoring loop.

Complete Race: The finishing order of races completed due to a red flag or completed under a full course yellow will be the running order of the last completed lap. The finishing order of races completed under waving yellow and checkered flags or red and checkered flags will be as follows:

A. Upon displaying the white flag to the leader, the race is considered complete. If there is an incident prohibiting the completion of the race and the checkered flag is waived with either the yellow or red flag the race will be considered complete and the finishing order will revert back to the position achieved when the leader crossed the finish line at the white flag.

B. If any karts have passed the finish line (scoring loop) before the yellow or red flag was displayed, they shall be scored as they finished. All other karts will be scored based on their positions on the last completed lap.

C. The competitors responsible for the red or yellow flag will be scored at the rear of the last completed lap they were running or be disqualified. A lap is considered to be complete when all karts on the lead lap have passed the finish line (scoring loop).

D. There will be a 20-minute time limit on all races. At the 20-minute mark, the Flagman will display the white flag to the leader at his or her next crossing of the scoring loop, no matter how many laps have been completed. The race will be complete after the checkered flag falls.

Grid: There is to be only one person with each driver in the grid area. Entrant may be ejected from event if more than one person is in the grid.

 Points after Disqualifications: In the event a driver is disqualified for unsportsmanlike conduct or driving, the driver must use that race finish in his or her national points and may not use the race as a “drop.” In the event of mechanical failure on the track, post-race engine, oil, or fuel tech, or being underweight, the race may be used as a “drop race.” However, if the driver is disqualified repeatedly for any reason, he/she could be subjected to the same penalty as unsportsmanlike driving or conduct. Any attempt to counterfeit or remanufacture OEM parts will result in a disqualification, and the race may not be used as a “drop race.”

Scratch Entries: If an entrant is scratched, the space shall be filled (a) if on the track, by moving karts forward directly and (b) if still on the grid, by crossing over to make the starting grid proper, based on the karts available for the race based on qualifying position.

Ninety Second Rule: All drivers have 90 seconds to start from the grid and enter onto the track at the beginning of the race. The competitor must be on the grid, in starting position, in the kart, and ready to race for the 90 second rule to be in effect for that competitor. Once the Grid Official radios to the Flagman and Race Director that the grid is clear and all karts have entered onto the track, the 90-second rule no longer applies. If a kart stalls after that and enters the hot pit to restart, he may do so; however, the race can start at any time and if the race starts before driver leaves the grid, he may not re-enter.

Race Format

All entrants will follow the same format.  Practice, at least one heat race, Consi(if needed) and Feature.

Pill Draw: Upon payment of entry fee each entrant will draw a number. Heat race line ups will be determined by this sequence.

B. If transponders are being used it is the competitor’s responsibility to have a transponder mounted on his or her kart. If no transponder is attached to kart, the competitor will not be scored.


Pit Area: That area of the track which requires a pit pass for entrance is restricted and under complete control of the race officials. The Race Director may limit the number of pit crew members who can enter this area to a set number per entry. All persons entering this area, whether connected with a driver or not, are subject to all regulations regarding deportment and behavior and may be ejected from this area by the officials in charge.

Insurance Regulations: Everyone, including race officials and track workers, who enter the track’s restricted area must comply with all registration procedures and insurance.
