Atwater Karting Speedway Rules and Regulations

2019 Rules and Regulations

AKRA/AKS Caged Classes 

The intent of this rulebook is to provide a set of rules and procedures to race by that make it as fair as possible for all to race and be competitive.  This rulebook will help establish the legality of karts and engines used at Atwater Karting Speedway.  Included in the following pages will be the rules to follow during the 2019 racing season.  

If at any time it is determined that these rules need modification, they may be amended to incorporate these rules.  It is the hope of the Atwater Karting Speedway staff that all who participate in the karting program be there to have fun and enjoy kart racing.  If a modification or an item of optional equipment is not listed specifically, it will be considered illegal and will not be allowed.    

RESERVED PARTICIPATION RIGHT: Atwater Karting Speedway (AKS) reserves the right to refuse to accept the entry of any kart or participant.  Furthermore AKS reserves the right to revoke or cancel any entry, or any participants claimed right to be on the track premises, if it is felt or determined that a participant or pit crew’s presence or conduct is not in the best interest of the sport of kart racing, the competitors, the spectators, and the board members of AKS.      

AKS board members reserve the right to call any event if they consider it unsafe for drivers or spectators or track personnel.  Board members also reserve the right to decide or change any item not covered in the rule book if it is deemed necessary.      

Raceway officials will decide if your kart or the operation of said kart is legal.

Pre-tech Inspection: 

All karts/drivers must go through a pre-tech inspection the first time they race at AKS.  Any safety issues must be corrected and re-teched before the kart or driver will be allowed on the track.  Once a kart has passed a pre-tech inspection the driver/owner is responsible for maintaining the kart in the same manner as it was inspected.  Should any infraction be found at any time the driver/kart will be disqualified with a loss of awards and points for that race.   

Remember, this is a family sport, be sure to involve fun and respect in your racing program.

Points System

Points will be awarded as follows:  

  • Heat Races: No points  
  • Feature Race Points: For a complete copy of the point scale, please contact the official scorer.  

The Track Score Keeper keeps Official Points.  Any driver taking the green flag but not finishing the race will receive points for last place at the time he/she pulls out of the race. If you start the heat and are not able to race in the feature due to accident or mechanical failure you will receive last place points.  

Any kart asked to leave the track for equipment reasons that pose a safety hazard after the green flag will receive the points for last place at the time he/she pulls out of the race.  

The official scorer must be notified if someone other than the driver at check-in is driving the kart. This must be done prior to the start of the race. Failure to do so will result in loss of points for the night. 

Total points for each scheduled event will be accumulated towards season points.  We are scheduled to race 10 events.  When a driver competes in all 10 events, the driver's highest 9 event scores, with the driver's lowest event score thrown out, will be used to determine the class champions.   

Any driver who receives a black flag will not receive points or a trophy for that race, unless the black flag was for safety reasons. A DQ score cannot be used as a throw out night for season points thus will be counted as one of the 9 event totals.

Season points go with the driver and his/her kart number.
