General Regulations

1. All classes will be run on a .4 pro tree. 2. Deep staging allowed at your own risk. The starter will not hold the tree. "Sure Start" will not be activated on the tree, so knocking off top bulb during the staging process will not result in an automatic redlight. "Auto Start" is activiated so once all four staging lights have been lit, the tree will automatically activate randomly around 1.5 seconds after last stage light was lit. 3. Courtesy staging (both top bulbs lit before final staging begins) will be enforced. Although, if a driver stages when his/her opponent has turned on both lights, he/she has accepted that run. The starter will back the driver who turns both bulbs on behind the line for one re-attempt at staging properly. If the driver once again fails to courtesy stage, then the driver will be disqualified and the win will go to the other lane. Staging games will not be tolerated. Once three stage lights have been lit, the unstaged driver will have 10 seconds to fully stage before tree will be activated or he/she will receive a redlight. Once both drivers have prestaged, the starter will give ample time for final staging to begin. After that, starter will motion BOTH drivers into the beams. At that point, 10 seconds will be given before the tree will be activated and if either or both drivers have not final staged, they will be disqualified. The word "courtesy" also applies towards the racers in the water box behind you waiting on their run. 4. Cars must come to lanes when called. After the third and final call, the round will begin. Those drivers who may be entered in multiple classes will be given enough time to complete their rounds. A driver can only enter one car per class. No two drivers can enter the same car in the same class. A driver may enter mulitple classes with the same car or multiple cars.  ***Any non-qualifier of a class with a qualified field (Top Street, True Street, and 5.30) may enter Pro Tree Eliminator at no extra cost.  5. Properly secured fire extinguisher is required on all entries running 7.49 or quicker in all classes.  On board fire system is required on all entries in Top Street, 5.30, and True Street.  It is recommended on all entries. 6. All cars running a PTRA class must report to tech. At events where host track bracket racing is held, those cars will only be teched according to regular track procedures. 7. 5.30 entries will be placed on a pro ladder beginning first round. 6.00, 7.00, and Pro Tree Eliminator will be placed on a sportsman ladder at the round of eight cars or less based on the previous round closest to the index/dial.  Until that point, they will run at random as they enter the staging lanes. Lane choice will be determined by the card system or coin toss if staging lanes are uneven, until they are placed on a ladder. 8. In the sportsman classes, the first round bye run (if available) will go to the number one qualifier. In the Pro Tree Eliminator last round of qualifying, all entries will dial in and the closest to their dial will be considered low qualifier, thus receiving qualifying points (1st thru 5th). (Reaction time will be used as the tie breaker for qualifying.) After that, closest to index or dial from previous round will be in line for the next bye. If the driver has already had one, then the next best qualifier will be in line. Once placed on a ladder, bye runs are set for the rest of the race, and lane choice goes to the closest to index or dial in previous round. Ties will be broken by reaction time, then by mph for lane choice. 9. In the Pro classes (Top Street and True Street), cars are placed on a sixteen car ladder pro style, i.e. 1 runs 16, 2 runs 15, etc. Bye runs are set for the entire race. Lane choice will be determined by qualifying for first round, then the quickest elapsed time from previous round for the remainder of the race. Ties will be broken by reaction time, then by mph for lane choice. 10. Bye runs must only stage and take the tree to get the win. 11. Once two cars are paired in staging, it is a race. If a car can't or loses fire, the pair will be placed at the end of the round for that class, or given five minutes, whichever is longer. At that point, the remaining driver gets a competition single, not a bye. Once either car begins a burnout, and a car loses fire, the driver will be given 2 minutes to refire. The opponent has the option of backing off and running at the end of the round, or five minutes later, whichever is longer, or taking the single run after the 2 minutes has passed. 12. In 6.00, 7.00, and Pro Tree Eliminator, no burnouts under power across the starting line. 13. No one without drivers license, or not of proven legal driving age will be allowed to operate a vehicle on host track property. Valid I.D. may be required if in question. 14. Absolutely NO ONE under the influence of ANY amount of drugs or alcohol will be permitted on the track (including drivers and crew). 15. Unsportsmanlike conduct or fighting will NOT be tolerated. Drivers are responsible for their crew members. Consequences will include but are not limited to forfeiting of all points and winnings. 16. Winnings must be picked up at the timing tower or payout window on raceday. No winnings will be mailed. 17. By entering an event, all drivers are releasing rights to the series promoters to use their names or likenesses in any media promotions for PTRA events. We want to promote you, the racer. 18. Any car deemed unsafe by the track officials for any reason will be disqualified from competition (including excessively ill-handling or dangerous driving). Event coordinator has final decision on all matters including safety, raceworthiness, legality, and unsportsmanlike conduct. 19. "Cheating" will result in suspension from PTRA competition. This includes but not limited to: using a timed throttle stop in an index class, using a nitrous progressor of any kind (manufactured or homemade) in True Street, changing weight between the scales and an actual run in Top Street or True Street, understating cubic inch in True Street. 20. Protest Procedure: In True Street, a competitor may protest another competitor by putting up a $100 protest fee to check cubic inch. Of that, $25 will be kept by the PTRA. If the protested vehicle is found to be legal, $75 will be forfeited to the protested driver. If the protested vehicle is found to be illegal, $75 will be returned to the protester, and the driver of the illegal entry will lose all points, winnings, and entry fees for that event and may be subject to a suspension or permenent expulsion from the PTRA and all PTRA sanctioned events in the future. Random spot checks can and will take place throughout all events to check for progressive controllers in True Street, the usage of timed throttlestops in the index classes, etc. A cubic inch protest must be made within ten minutes of the end of the last qualifying round. All protests must be made by a competitor entered in the same class on the day of the event. At all events, any True Street competitor is subject to a P and G cubic inch test.  In all classes, random spot checks can and will be performed in the staging lanes.

Points and Number system

1. By joining the PTRA, a driver is entered into points for one class. A driver can enter more than one class. The top five points finishers of 2007 will be encouraged to use their respective placement number as their car number in 2008, if they wish. For example, the second place points earner in 7.00 could have the number 2 in the top corner on passenger side front windshield. Lower on the windshield, under the car number, the competitor would have 7.00 written as the permanent dial-in. Competitors should use the following prefixes in front of their number, in the other respective classes: Top: Top Street TS: True Street PTE: Pro Tree Eliminator PS: Performance Street  2. Competitors will earn points in the following manner: 20 points-enter 10 points-per round won 30 points-win bonus 20 points-runner-up bonus 5 points-number 1 qualifier bonus 4 points-number 2 qualifier bonus 3 points-number 3 qualifier bonus 2 points-number 4 qualifier bonus 1 point-number 5 qualifier bonus 3. Participants will be allowed to drop one race from the total available race schedule. However, they are of course encouraged to participate at all races to get their best possible points total. 4. Competitors need to enter the points program at the tech trailer to be eligible for points before the first race to be claimed. The cost to join the PTRA will be $50 for the year. This includes one class points entry, T-shirt, required decals, rulebook, and one year subscription to Atlantic Racing Review magazine. Any additional class points entry will cost $10. Points cannot be transferred from one class to another by a driver. Points cannot be retro-accumulated. Points totals begin when a driver enters the program. Drivers can enter points in multiple classes. Drivers can also join the PTRA/points at Atlantic Racing, or by downloading the form on headsupsuperseries.com, and mailing it in.
