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.

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

VII. STARTING PROCEDURES
1. Qualifying heat races will be held at all events.
2. The car count at the close of the drawing for qualifying heats will determine the number of heats to be run. As each number is drawn for a car, that number will be posted and this procedure will be repeated until a number has been drawn for each car that wishes to compete. The lowest number goes to the pole of the first heat race; the next lowest drawn number goes to the pole of the second heat, etc. Once pole position in each heat is filled, the next lowest number goes to the outside front row of the first heat, etc. If there are an uneven number of cars to equally distribute between heats, the last cars will be placed at the back of the lowest numbered heats. Any cars not represented at the drawing shall be placed at the rear of a heat race. Heat races will determine the starting position for the balance of races scheduled.
3. The passing point system will be used to determine starting positions in feature events. The driver will receive points for passing as well as finishing position, with a pill draw inversion of 4, 6 or 8. Any driver failing to draw for heat races or pack racing surface (when requested) will not receive passing points, but only points accumulated through his finishing position in his heat race. In the event of a tie in passing points, the Driver who first earned the points shall be aligned in front of any subsequent driver earning the same number of points. Passing points will be figured on the actual starting position on the final parade lap.
4. Time Trials may be held at some shows, depending on car count.
5. A car and driver qualify as a team. Each driver can qualify only one car. No driver will be permitted to change cars after taking the green flag of his qualifying heat race. An exception to this rule will be in a two day race.
6. TGSS or their representative will advise drivers of the make-up of the number of heat races, main events, field maximum size and other pertinent information at the drivers meeting.
7. The lineup posted on the pit bulletin board when cars enter the racing surface for any race shall be the final line-up. In the event a car drops out of the line-up for mechanical reasons, the balance of the field shall move straight forward. The exception being, if 2 cars drop out from same row, prior to green flag.
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. In the event a pace car is not used, the pole car will set the pace which shall be consistent with track conditions and as required to keep the field in formation. TGSS shall be empowered to disqualify or penalize any driver violating this rule.
VIII. POST RACE PROCEDURES
POST RACE INSPECTION
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.
2. Any of the top finishers not reporting to the designated inspection area will be disqualified.
