The purpose of the Top Gun Sprint Series (TGSS) is to promote and conduct sprint car races and other racing oriented events. In this pursuit, the TGSS has formulated and adopted the General Safety, Competition, and Technical rules contained herein. These rules will become effective and enforceable as of the date of this publication and will constitute the rules and regulations that shall govern the conduct of all racing events sanctioned by the TGSCS.

All car owners, drivers, sponsors, crew members, and all persons involved in any way in any TGSS sanctioned racing events, shall be deemed to have read, understood, and agreed to comply with these rules and any and all amendments, supplements, and/or revisions that may be implemented. It is, therefore, recommended that all of the above listed entities read the rule book carefully to assure familiarity with the rules and regulations contained herein.

The rules and regulations as set forth herein are intended to establish minimum acceptable standards and requirements for all racing events. No expressed or implied warranties of safety shall result from the publication of or compliance with these rules and regulations. They are intended as a guide for conduct of the sport and are in no way a guarantee against injury or death to participants, spectators, or others.


The TGSS Rule Book is not the only authority governing the actions and activities of the individuals who participate in a TGSS sanctioned racing event. We remind all participants that each race track where a TGSS sanctioned event is held is located within the boundaries of a particular city, county and state and is, therefore, within the jurisdiction of all the law enforcement agencies operating and having authority within these areas. Thus, all laws and statutes applicable to these areas are enforceable at each racetrack where TGSS sanctioned events are held and all violations will be dealt with accordingly by the various law enforcement agencies.


I. The TGSS expects and requires all participants in a TGSS sanctioned event to conduct themselves in a respectable manner and to display proper sportsmanship. Any race team’s authorized spokesman or unauthorized person making an abusive or unpleasant statement to an official may result in the race team being fined as follows:

First offense $50.00
Second offense $250.00
Third offense Two (2) race suspension.

All fines will be taken from said race team’s nightly payoff and will be put in the TGSCS point fund.

II. The car owner/driver shall be responsible for the actions of the pit crew while at any TGSCS sanctioned race. In addition, each pit crew member is equally responsible for his or her actions.

III. The driver and one other designated person shall be the only spokesman for their particular crew.

IV. No member shall enter the judge’s tower or approach the starter’s stand for the purpose of lodging a complaint or disputing a decision.

V. No member shall use abusive language or threaten bodily harm or equipment damage when addressing another member, club officer, or track official or subject such persons to unwarranted physical contact.

VI. No driver or pit crew member shall drink intoxicants or use narcotics during any racing event. Any driver or pit crew member, who arrives at a racing event and, in the opinion of the TGSS officers, pit steward, or race director, is under the influence of intoxicants or narcotics will be denied participation in that event.

VII. When a car is started in the pit area, it is required that the driver be wearing his driving suit, seat belt, harness, and helmet properly fastened.

VIII. No speeding or unsafe driving will be allowed in the pit area. 5 MPH speed limit at all times in the pits at all tracks.

IX. Any driver, while racing, who commits unnecessary contact or harassment or uses any driving tactic, whether intentional or not, that is considered dangerous by the starter, pit steward, or race director, will be deemed to be rough driving and subject to suspension at future races and/or loss of points as determined by the officials.


A. The interpretation and application of all rules contained herein as well as all amendments, supplements, and revisions that may be implemented, shall be at the sole discretion of the TGSS officers and race director.

E. A car pitting under the yellow cannot return to the track if more than a lap has been completed under the ensuing green flag.

F. Pit crew members will not be allowed on the track unless permission has been granted by an official.

G. No repairs will be made on the track. Any car that pulls off the track during a restart situation will automatically restart at the end of the lap they were running on. In the event that more than one car pulls off, the last to return will start last on the lap they were running on and the others will line up in the order they return to the track on the end of the lap they were running on. Any car stopping on the track for other than a red flag situation will be placed at the rear of the lap on which they were running. Any car committing a 360 degree spin that results in a
Yellow flag will be placed at the rear of the lap they were running on. Any car passing prior to the drop of the green flag will be placed at the end of the lap he was running on. A second infraction of this type will result in the disqualification of the car for the event.

If there is a restart within five (5) laps of the end of the feature, lapped cars will go to the rear. For the restart, the appointed TGSS representative will be stationed at the start finish line and will place orange cone one and one half car widths from the outside wall. On all single file starts after one lap the restarts will start at a Cone to be placed on the front straight-way. The leader must start at or near the cone and all cars must go outside of the cone in proper aligned order. Leader must set a consistent pace. Any car going inside of cone, hitting cone or passing a car prior to going outside of the cone will cause a yellow and be placed on the rear.

8. The start will be official only upon the starter signaling with the green flag. In the event a pace car is used, all cars shall take their proper position behind it.

TGSS shall be empowered to disqualify or penalize any driver violating this rule.



1. At the completion of the heat and feature, the top three (3) in the heats and top five (5) finishers in the feature will report to a designated post race inspection area. The designated area will be announced at the mandatory TGSS driver’s meeting by the TGSS director of competition. As a reminder to all, the designated area will be written on the feature line-up board. No excuses for not knowing the location of the inspection area will be allowed. If you are not sure of your finishing position, report to the inspection area and you will be notified by TGSS officials if you’re in the top five.
