RULE BOOK DISCLAIMER 
IF THE RULES DO NOT SAY YOU CAN, THEN YOU CAN NOT 

 

The rules and/or regulations set forth herein are designed to provide for the orderly conduct of racing events and to establish the minimum acceptable requirements of such events. These rules shall govern the condition of all such events, and, by participating in these events, all participants are deemed to have complied with these rules. NO EXPRESSED OR IMPLIED WARRANTY OF SAFETY SHALL RESULT FROM PUBLICATIONS OF, OR COMPLIANCE WITH, THESE RULES AND/OR

REGULATIONS. These rules are intended as a guide for the conduct of the sport and are in no way a guarantee against injury or death to a participant, spectator, or official. The Pro Truck Race Director or Official in charge, shall be empowered to permit minor deviations from any of the specifications herein or impose any further restrictions that, in his opinion, do not alter the minimum acceptable requirements. NO EXPRESSED OR IMPLIED WARRANTY OF SAFETY SHALL RESULT FROM SUCH ALTERATION OF SPECIFICATIONS. Any interpretation or deviation of these rules is left to the discretion of the Pro Truck Race Officials, and their decision is final. Regulations and specifications set forth herein are automatically amended by directions contained in subsequent Official Entry Forms and Official Technical Bulletins issued by Pro Truck. All specifications and regulations contained herein are subject to deletions, additions, and/or modifications by the above or by verbal directive of the Pro Truck Series Director or Pro Truck Technical Director without expressed prior notification. 
GENERAL RULES 

 

Continuous developments in racing may necessitate changes that cannot be anticipated at the time rules are formulated. Hence, if necessary, rules may be updated, modified, added to, or deleted at any time, as needed. In addition to this, the “Except in Rare Instances” rule will be in effect at all times. Pro Truck intends for all trucks to be competitive with each other. If you do something to your truck that these rules have overlooked, and that Pro Truck feels gives you an unfair advantage over other competitors, you will be required to reverse these changes or add weight. If there is a question on any rule herein, on specifics or clarification, the best “rule of thumb” is, if you do not see something specifically explained, consider it illegal, because the Pro Truck officials will.

Driver may have a substitute in his or her place when prior approval has been granted by the Chief Steward. Substitute will be responsible for replaying any information to the absent driver. 

1.4.2 All race trucks must move under their own power to staging. No pushing. 

2.0 – Lineup, Points and Pay 

2.0.1 Qualifying order will be determined by your position in the point standings. Any driver without points will go first followed by the lowest driver in the point standings, the order will make its way to the point leader
. Qualifying will allow for 2 timed laps. The best time recoded will be the time used for that truck. In the event of a double main event the first lap may be used for the first race and the second lap for the second with points awarded for each lap. If one driver will compete in the first main and another in the second each will qualify one lap. Any driver not ready to qualify when his or her turn comes will be allowed to qualify last but will only be allowed one timed lap. Any Truck not qualified within three minutes of the last qualifier will not be allowed to qualify and will start scratch with no passing points awarded. The fastest 4 qualifiers will be held in the inspection area and will be inspected. Pro Truck Officials will be empowered to pull a mystery guest to the inspection area after qualifying. Pro Truck Officials reserve the right to start any truck at the rear of the field for the heat and main event based on the time that truck posted in qualifying. Any truck posting a time of .5 seconds or more from the fourth fast qualifier will be started at the rear of the field ahead of any scratch Trucks. When multiple trucks fail to post a time within .5 seconds of the fourth fast time they will be lined up fastest to slowest based on time at the rear of the field ahead of any scratch trucks. Any truck outside of the .5 time or starting scratch will not receive any passing points. All trucks inside the .5 seconds of the fourth fast time will be inverted and will be eligible for any passing points awarded in that event. (Removed 2 race requirement)


2.0.2 Heat Race lineup. The Heat races will consist of a minimum of 6 trucks and a maximum of 11. In the event of more than one heat race the fastest qualifier will start at the rear of race 1, the second fast at the rear of race 2 and so on. When the amount of heat races is achieved the next fastest qualifier will start next to the fastest at the rear of the first race and so on until the lineups are set.

 

2.0.3 Main Event lineups. The main event line up will be determined by the qualifying results. As described above

2.0.4 Qualifying points. Qualifying will hold a point value of one point per qualified truck for the fastest time and will drop by one point per position with the slowest qualifier receiving one point. Qualifying will also determine where you will start in your heat race and main event. The fast qualifier will receive 2 bonus points. Trucks may run tape on the nose during qualifying 

2.0.5 Heat race points will be awarded for finishing position with one point available for each truck. If a race has 10 trucks the winner would get 10 points, second would get 9 and so on. When one heat race has more trucks than the other the winner of each race will receive the same amount of points.

2.0.6 Main event points will be awarded as follows. Two points will be awarded for each truck taking the green flag. In addition to finishing points passing points will be awarded. One point will be awarded for each position gained at the completion of the main event. (See example 1) Any truck starting scratch will not be eligible to receive any passing points.

Example 1- If you take the green flag in 10th place and cross the line at the checkered flag in 5th place you would get 5 additional points (one for each position gained).Special events and double main events may have a modified point system or require a modification to the lineup. If a modified system is to be used for a particular event all driver will be notified at least 10 days prior to the event. 

A caution cone will be used for restarts in the main event. After the line up has been set a cone will be placed on the designated place on the track. You will have the ability to choose high or low as you pass the cone. If you were involved in the caution or entered the pit area during the caution you will not be allowed to use the cone, you will be required to go low when you come to the cone. Lapped trucks will drop to the rear of the field ahead of any pit trucks and will be required to take the low side when approaching the cone. The first truck a lap down will receive the lucky dog. The truck will drop to the rear of the field behind all other trucks on the track and will be credited with one lap. After passing the cone the field will be shown 2 at the line signaling 2 laps to the green flag. In the event a lap is not completed under green the field will be reset with involved trucks moved to the tail end of the longest line. 

 

2.0.7 Event Points: Event points will be awarded as follows. Any truck proven to or determined to be race ready by the Pro Truck Officials will receive point for the event. Points will be awarded at the scheduled time of qualifying for each event. In the event a rain out happens no makeup dates will be scheduled but points will be awarded as long as the rain out has not been announced prior to the specified qualifying time. In the event the rain out has been announced prior to the specified qualifying time no points will be awarded. Points will only be awarded to trucks with drivers in the restricted pit area holding a valid pit pass for the night of the event. On any scheduled “Double Main” (one night two races) event points will only be awarded one time per truck. Two day events each day will be treated as an event and points will be awarded both days. Twenty five event points will be awarded to the driver that night or primary driver in a substitute situation for each even as described. Any truck failing pre or post-race inspection will forfeit event points as described above. In the event the failure is pre-race and corrections are made before the race begins points for the race will be awarded but the twenty five event points will be forfeited. The definition of pre-race is any inspection done at the race track on the day or night of the racing event.

2.0.8 Receiving Points. (removed drop race and sub driver) Any driver in good standings will receive points for the truck number they have established as their number. In the event a driver competes in a truck that displays a different number the points will be awarded to the established driver under his or her number. This change will require getting approval from the Race Director as well as the owner of the registered number. Only one driver can earn points for a number in a night.  

2.0.9 Pay Structure. All drivers will receive the pay for the purse. These dollars will be equally based on the amount of trucks. Additional bonuses, Sponsor monies, Sponsor prizes etc will be awarded on the total points earned in a night not necessarily to the race winner. 

2.0.10 Sponsorship dollars will not be included in the nightly purses but will be added to the championship point fund. Those dollars will be divided up equally to the per point earned in the championship chase. (See example 1) To be eligible to receive point fund dollars a driver must be in the top 10 in the final point standings or must not have missed more than two events.

Example 1 – If 1,000 dollars are available and the total point added up between all competitors is 500 points each point will be worth 2.00 and you will get 2.00 for every point you have. If 2,000 dollars is available and the combined points equal 2000 you will get one dollar for every point you earned in the season and so on. 

 

2.0.11 Championship Owner Points will be awarded based on the Trucks performance during the season. Owner points will be available to anyone fielding a truck with multiple drivers that does not have primary driver points assigned.
