Hannah's Frozen Nitro Junior Dragster (2 classes in 2013... Junior Pro and Junior Sportsman)
JUNIOR PRO: Dial-in 7.90 - 9.89 only. Breakout rules apply. In qualified events, no competitor can qualify quicker than 7.900. See also Breakout Rules in Race Procedures. If a driver has no previous experience in Jr. drag racing, he or she must successfully demonstrate driving proficiency prior to competition. Any competitor running quicker than 7.50 e.t. in the eighth-mile or 4.10 e.t. in 330 feet or faster than 85.00 mph at any time during eliminations will be disqualified from the event.
Any competitor running quicker than 7.50 e.t. in the eighth-mile or 4.00 e.t. in 330 feet or faster than 89.99 mph at any time during time trials or qualifying will be disqualified from the event and will be subject to additional disciplinary action in the sole and absolute discretion of NHRA.
JUNIOR SPORTSMAN: Dial-in 9.90 and slower. If a driver has no previous experience in Jr. drag racing, he or she must successfully demonstrate driving proficiency prior to competition.
Break Out: If any racer runs below their posted dial-in during eliminations, they are disqualified with the following exceptions: (1) when an opponent foul starts or crosses a boundary line (2) on a single run when both drivers run under their dial-in, the driver who is the least under is the winner (3) if both cars run under their dial-in by an identical amount, the driver crossing the finish line first is the winner.
Break Rule: There is no break rule for bracket eliminations. You will receive points and/or money, if any, from the last round you completed. If you do not show up for the round, you are considered forfeited from competition and do not receive money/points for that round. No refund or credit will be given once a car has been staged, regardless of TNT, Time Trials or Qualifying at any event.
Burnouts: No one will be disqualified for burning out across the starting line. HOWEVER, in the interest of moving the event along, we ask that you NOT burnout across the line if it is not necessary. No person is permitted to hold or touch cars during burnouts.
Buy Backs: Buy backs will be available at the front gate. Exception: Buy Backs for large events may be sold in the bottom floor of the Tower but will be announced if this is the case. Buy backs are available for first round losers only, except as noted on any special event where first OR second round buy backs can occur. Buy backs will run with first round winners in the second round of competition.
Bye Runs: Bye runs are only utilized in situations where there are an odd number of cars in the round. There is no entitlement to a bye run and bye runs are not accrued or carried forward. If your car is pulled aside for a potential bye run and it turns out that there is an even number of cars in the round, you are not awarded a bye run and you do not retain entitlement to the bye run.
In situations where a driver is making a bye run, he or she is considered the winner once the car stages and receives the start signal or is declared the winner by the Official Starter. This means the driver can choose to actually make the bye run, in which case the car must stage under its own power, or the driver can simply stage, take the start signal then back out of the lights. Lane boundary crossing and red light disqualification rules do not apply on bye runs. If a competitor crosses the center line on a single run, the elapsed time is voided for lane choice determination.
A competition bye does not make a racer ineligible for an odd lot bye. Those who have already made a bye run are not eligible for another bye run until all remaining competitors have received a bye run as well. Buy Backs will be eligible for bye runs after a winning round.
The potential first round (only) bye run of eliminations will be awarded to the first car to arrive in the front of the lane when there is only one lane assigned to the class. If there are multiple lanes for a class, the Staging Director will determine which car gets pulled aside for the potential bye run by pulling two chips. The first chip denotes from which lane the potential bye car is selected and the second chip denotes which car in that lane is selected for the potential bye. Bye runs must be accepted for the round they are utilized.
After first round, potential bye runs will be awarded to the winning driver with the best reaction time in the previous round. In cases of identical reaction times, the best total package will receive the potential bye run. In cases of identical packages, the bye run will go to the racer whose “best package run” was made earliest in the day.
Dial-Ins: Your dial-in must be written LEGIBLY on the left side of your race vehicle. Dial-in boards are also allowed. Dial-ins must remain visible on the outside of the vehicle at all times. “Flashing” of dial-ins to the tower in an attempt to deny that information to your competitor is not allowed and is grounds for disqualification. Dial-ins cannot be changed once the racer passes the fenced entry into the burnout area. This point is noted by a sign. It is the driver’s responsibility to check their dial-ins on the scoreboards prior to staging. No re-runs will be allowed because your dial-in was entered into the computer incorrectly and you or your crew failed to see the discrepancy. When you stage, you accept the Dial-in.
Bikes will be required to have some type of dial board and permanent numbers legible on the motorcycle.
Dual Infractions: In the case of dual infractions on a competitive run, the one making the worse infraction will be disqualified. If infractions are of an equal rank, the first infraction shall be disqualified. In cases where both opponents in a race have mechanical difficulties prior to the start, every effort will be made to determine a winner and a loser of the contest. When possible this includes the allowance of a reasonable time period for the contestants to make adjustments and repairs and to complete the race. This rule also applies to cars making single runs. EXCEPTION: If both cars cross the centerline they are both disqualified. If both cars leave the line before the tree is activated, they are both disqualified. These exceptions notwithstanding, in the final round the car crossing the boundary line first will be disqualified, per the NHRA Rule Book.
Excessive Braking: Anyone who locks up the brakes and/or smokes the tires through the traps or past the finish line will be disqualified. No protests are allowed. All decisions are final.
Lane/Boundary Crossing: It is considered a disqualification when any portion of a tire completely crosses the painted line surface. Contact with guard railing, barrier, or any other track fixture (rubber cones, when used, are considered visual aids, not fixtures) is grounds for disqualification. Intentional crossing of boundary line to leave track or avoid depositing debris on strip is not grounds for disqualification. Crossing the centerline during a burnout is not a disqualification.
Lane Calls: For eliminations, the Tower will make 3 calls to the lanes over the PA system. These can also be heard over the Track’s FM radio broadcast station of 102.7 FM. Shortly after the final call is made, we will close the staging lanes at the BACK of the lanes. Once the last row of cars have been pulled forward to the front of the staging lanes and the next class is stopped at the mid lane stripe, the class is closed and no late entries will be run. Make sure you listen for your lane calls. BE PROMPT. If you arrive late, you will be sent back to the pits and are disqualified.
Lane Choice: There is no lane choice during eliminations. The Staging Director will assign a lane to each car as they are pulled out of the staging lanes. When a car is pulled out for a potential bye, and one is not utilized due to an even number of cars in the lane, the car pulled out for the bye run gets lane choice.
Pairings: When your class is called to the lanes, proceed to the mid-line strip in the lanes immediately. During time trials, odd lanes will be Tower lane and even lanes will be Spectator lane. In eliminations, all 10 lanes will be used for all classes. Staging Lanes Coordinator will direct you to the next lane, no exceptions or favorite lanes will be allowed. In eliminations the potential bye will be pulled aside and cards will be used to pull the lanes. The Head of Staging will draw lanes based on cards drawn. The first card drawn will be the Tower lane and the second card drawn will be the Spectator lane. When there are no more than three rows of cars and the third row does not have all 10 lanes filled, the Head of Staging may, at his discretion, pull cards out of the deck so that the last row ends up with all lanes filled.
For example, If Super Pro is called to the lanes, proceed to the lanes and watch for the staging lane coordinator to point you to the next open lane. If your car is at the front of the staging lanes and the Head of Staging first pulls a '4' and then pulls an '8', the car in Lane 4 will race in the Tower lane, while the car in Lane 8 will race in the Spectator lane.
Once you have been paired, your opponent will receive a competition bye run if your car breaks or you cannot come to the starting line within two minutes. This decision is at the discretion of the starter and/or race director.
Once the last row of cars have been pulled forward to the front of the staging lanes and the next class is stopped at the mid lane stripe, the class is closed and no late entries will be run. Make sure you listen for your lane calls.
Re-Runs: Re-runs will only occur at the sole discretion of the Race Director.
Single Runs: Will be avoided at all costs to help maintain a consistent pace for the program.
Staging: You must courtesy stage. Auto-start will be on at all times. Deep Staging is NOT allowed. If either of your stage bulbs is out when the tree activates, you will get a red light. If you have problems behind the starting line, your opponent will be given a single once the starter has determined you cannot make it to the line within 2 minutes. This call is at the starter's discretion and it is final.
To be a legitimate winner, a contestant’s race car must self-start and self-stage. Motorcycles and Junior Dragsters may use external starters. This rule also applies to single runs. Push-starting or push-staging any vehicle is prohibited. Staging must be done under the vehicle’s own power. Motorcycles are allowed to restart as necessary, however, this must be done in a time frame that permits the contestant to complete the run with the designated opponent. In these cases, the rider will be allowed 2 minutes to restart and stage. If the opponent has been sent on a single run, the bike losing fire may not restart and the run is forfeited. For Junior Dragsters, see Junior Dragster rules.
Un-Sportsmanlike Conduct: The Driver is responsible for his/her actions and the actions of his/her crew. Drivers and Crew members at an event shall conduct themselves according to the highest standards of behavior and sportsmanship, particularly in relation to other competitors and track officials, and in a manner that will not harm the reputation of the NHRA, Tulsa Raceway Park or the sport of Drag Racing. Failure to do so may result in penalties ranging from disqualification from the event to being banned from Tulsa Raceway Park at the discretion of Tulsa Raceway Park Officials. All rulings are final.
Vehicles: Drivers cannot change vehicles after eliminations start.
