Advanced:                                          Age 13 to 18               ET 7.90 or slower with a max speed of 85 mph

 

NHRA safety requirements are enforced

 

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. No refund or credit will be given once a car has been staged, regardless of TNT, Time Trials or Qualifying at any event.

 

Re-runs: Re-runs will only occur at the sole discretion of the Race Director.

 

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 race vehicle during burnouts.

 

Re-Entry:  All Re-entry cars run the re-entry round in their class. Only the winners advance to 2nd 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 disqualifications 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.  Re-entries will be eligible for bye runs after 2nd round.

 

 The potential first round (only) bye run of eliminations will be awarded with a random card drawn by the Official Stager.  After first round, potential bye runs will be awarded to 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. 

 

Single Run: Will be avoided at all costs to help maintain a consent pace for the program.

 

Dial-in: Your dial-in must be written LEGIBLY on the left side of your race vehicle.  Dial-in boards are also allowed.  Dial-in must remain 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.  Racer is responsible for having their  number on the left side of the car visible at all times during a race. 

 

Bikes will be required to have some type of dial-in board and permanent numbers displayed legibly on the left side of motorcycle. 

 

 

Dual Infraction: 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  loser of the contest.  When possible this includes the allowance of  reasonable time period for the contestants to make adjustments and repairs and 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 pained 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.  Intensional  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 Call: There is no lane choice during eliminations.  The tower will call you to the lanes by classes over the PA system.  This can also be heard over the tracks radio FM 102.7.  When you are called to the lanes proceed immediately.    The Staging Director will assign a lane to each car as they are pulled out of the staging lanes.  When a car is pulled  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 get lane choice.  The Staging Director and Manager of Race will have the final decision. 

 

Paring: When your class is called to the lanes, proceed to the staging lanes immediately.  During time trials, odd lanes will be Tower lane and even lanes will be Spectator lane.  In eliminations the potential bye will be pulled aside and cards will be used to pull cars.  The first card drawn will be the Tower lane and the second card drawn will be 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 Stager and/or the Race Director.

Once the last row of cars have been pulled the class is closed and no late entries will be run.  Make sure you listen for your class and lane calls.

 

Re-Runs: Re-runs will only occur at the sole discretion of the Race Director.

 

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

 

Winner:  To be a legitimate winner, a contestant’s race car must self-start and stage.  Motorcycles and Junior Dragster 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 Juniors Dragster, see Junior Dragster Rules. 

 

 

Un-Sportsman like 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 Osage Casino Tulsa Raceway Park at the discretion of Tulsa Raceway Park Officials.  All rulings are final.
