Beginning January 1st, 2024, A head and neck restraint device/system meeting SFI 38.1 is mandatory for any vehicle running 150 mph or faster for 1/4 or 1/8 mile or running 7.49 (*4.49) E.T. or quicker or by Class Requirements. An SFI 38.1 head and neck restraint device can be used with, or without, a neck collar; when a neck collar is not used, an SFI 3.3 head sock or SFI Spec 3.3 skirted helmet is required.
BIR requires all cars running faster than 9.99 in the quarter mile, 6.39 in the 1/8th mile or 135 mph and faster to have a NHRA-accepted lower engine oil–retention device (diaper); A belly pan may be used in lieu of a device attached to the engine. If a belly pan is used, it must extend from framerail to framerail and extend forward of the harmonic balancer and rearward to rear engine plate incorporating a minimum 2” lip on all sides. A non-flammable, oil-absorbent liner mandatory inside of retention device.
When exiting the dragstrip, the left lane car has the right of way. Right lane cars must wait for left lane cars to exit first. Do not cross over in front of the left lane car, wait for him to clear you or exit the track before exiting. There are 3 exits past the 1/4 mile, so when in doubt, keep going to the last exit. Do not ever turn around on the dragstrip.
The flashing red lights on the Christmas Tree is a signal that the starting line area and track surface is closed to racers and crew, please clear the track. Only track officials should be on the track surface at this time. This will typically occur for track prep, equipment in use, track clean ups, or an on-track incident. Please help to keep the starting line area safe by following this request.
“What does the orange cone on the starting line mean?” If your vehicle has street tires, you will be “coned” when you pull up to the starting line. This means that you must keep your wheels aligned with the orange cone and out the of the “groove” on the racing surface when you’re making your pass down the track. Street tires tear up the surface rubber and we want to that groove for vehicles running drag slicks/radial tires.
Tow vehicles permitted. Only One Tow vehicle per racer will be allowed to top end. All passengers must ride in a seated position. "To ensure everyone's safety, only those who can fit in the available seats can ride. No “Razor Scooters” allowed past ET shack.

Note: this applies to any event on the drag strip, including but not limited to, each Muscle Car series event (Street Car Showdown, Show N Go, Muscle Car Shootout), Bracket Race (per race day as each is a separate event), or Karmageddon.
An “clean-up” is defined as any incident requiring the use of mechanical equipment (i.e., tractor, truck, tenant, sweeper, etc.) to clean up fluids (e.g., engine oil, gear oil, anti-freeze, transmission fluid, etc.) deposited on the track by a race vehicle (car, dragster, bike, sled, etc.). Spills or drops of fluids cleaned up by hand are not considered violations and penalties will not apply. On occasion, equipment will be used to touch up the racing surface. Such maintenance is not considered a clean-up. This policy encompasses the entire length of the “track surface”, including but not limited to the staging lanes, burnout box, starting line, racing surface and the shutdown area to the point the vehicle exits (including the turnout area if clean-up results in a delay of the race).
The removal of objects such as blower belts or miscellaneous parts from the track surface does not constitute an “clean up”. It also does not apply to fuel, fire extinguishing systems, drive line parts (not including fluids), wheels, tires, brake systems, etc. An oil/liquid cleanup resulting from a crash will not result in a penalty unless the accident was a result of depositing oil/liquids on the track.

When exiting the dragstrip, the left lane car has the right of way. Right lane cars must wait for left lane cars to exit first. Do not cross over in front of the left lane car, wait for him to clear you or exit the track before exiting. There are 3 exits past the 1/4 mile, so when in doubt, keep going to the last exit. Do not ever turn around on the dragstrip.
The flashing red lights on the Christmas Tree is a signal that the starting line area and track surface is closed to racers and crew, please clear the track. Only track officials should be on the track surface at this time. This will typically occur for track prep, equipment in use, track clean ups, or an on-track incident. Please help to keep the starting line area safe by following this request.
1. Seat belts must be worn and adjusted in such a manner that the driver’s torso and head cannot extend outside the parameters of the roll cage. Loosening or removing seat belts, helmets, gloves and window nets, lifting the helmet shield, and removing any other safety equipment is prohibited from the time the vehicle leaves the ready line until the vehicle is on the return road. Violators will be subject to disciplinary action at the sole and absolute discretion of the event director and/or NHRA. Please remember to buckle your helmet, our start line crew is watching!
2. As a courtesy to all the drivers, please get to staging lanes promptly when called, there will be a total of 3 calls to staging. Lanes are closed when the last pair enters the burnout box.
3. The official has the final say in all cases. The computer is an official.
4. Stay with your vehicle in the staging lanes. Be ready ahead of time for your pass. If you are not ready to run when called, you may be disqualified. The decision will be final.
5. The pairings are determined by the staging director in the staging lanes. The director’s pairings are final. You will race who you are paired with or lose the round by forfeit. The director will use system generated ladders or a random drawing system to determine these pairings depending on class. These pairing decisions are final.
6. In the event cars have been paired up and called to start and one fails to start or move, the non-offending competitor will be required to take the tree. A vehicle must leave the starting line forward, under its own power, to be eligible for a win.
7. If a vehicle has problems before staging, it will be given 30 seconds to re-start or correct. Actual time allowed will be at the discretion of the starter and based on the situation at hand. The starter shall have total discretion of the time allotted to stage a pair of vehicles and activate the tree. Track officials will make every effort to determine winners on the racetrack by competition, not by disqualification. His decision will be final.
8. Auto-start will be used in all classes. Movement of a “staged” vehicle after the tree is armed, will result in a red-light foul, even though it may occur before the tree counts-down. Also called a “shallow-stage red” it is not grounds for protest or re-run.
9. You cannot enter two drivers in one vehicle in any BIR classes. You may not switch drivers once eliminations have begun. You must finish eliminations with the vehicle/driver combination you started with.
10. No burnouts in the staging lanes or pit areas. No stationary burnouts – except in the water box. Power burnouts across the line are not allowed unless directed by a track official. One (1) backup is allowed to all competitors, for the purpose of re-positioning their vehicle on the starting pad. The car must always pull forward into a staged position; backing into a staged position is dangerous and strictly prohibited!
11. In case of vehicle malfunction, please move your vehicle out of the groove and next to the guard wall. This may keep oil from your car off of the racing surface.
12. Byes round one will be a random pick. Subsequent rounds will be decided by ‘best reaction time’ in previous round until it becomes system generated (on a ladder). A driver awarded a bye will ‘carry’ that bye until used or is eliminated from competition, then a new ‘bye’ will be chosen. A driver who has the ‘bye run’ must leave the starting line forward, under its own power, to be eligible for a win. Drivers will not be eligible for a second bye run until class is on a ladder.
13. For all classes on a ladder round 1 the driver with the better qualifying elapsed time will get first-round lane choice, subsequent rounds will be determined by a coin toss.
14. All protests and appeals must be made through the race director. Filing a protest during an event does not disqualify any entry until that entry is proven to be illegal by BIR or NHRA officials. NHRA rulebook procedures will be followed in all cases of protest, and in all instances no other entries will be reinstated based on the outcome of the protest. If someone comes to an official with a rule's infraction on a competitor's car, they need to go with the official to offending driver & vehicle to explain the infraction on the vehicle. If they won't, then the infraction will stand unless we have another reporter who will.
15. Safety gear such as helmets, jackets and seatbelts must not be removed or loosened, and windows must remain rolled up until you have exited the racing surface.
16. If the official time or race results need to be checked, please check with the Race director for the event. BIR reserves the right to confirm or overturn a race result based on recorded video or official eyewitness account. Please retain your time ticket for the last round you ran, you may need it for verification.
17. All drivers and crew members entering a restricted area must sign the appropriate Waiver and Liability Releases. Minors under the age of 18 must have a Minor Release Form signed by both parents or legal guardians. In the case of a single parent (by means of divorce, death, or court order) or a legal guardian (by court order), a written notation must be made in the minor release form.
18. Tow vehicles permitted. Only One Tow vehicle per racer will be allowed to top end. All passengers must ride in a seated position. "To ensure everyone's safety, only those who can fit in the available seats can ride. No “Razor Scooters” allowed past ET shack.

An “clean-up” is defined as any incident requiring the use of mechanical equipment (i.e., tractor, truck, tenant, sweeper, etc.) to clean up fluids (e.g., engine oil, gear oil, anti-freeze, transmission fluid, etc.) deposited on the track by a race vehicle (car, dragster, bike, sled, etc.).

The removal of objects such as blower belts or miscellaneous parts from the track surface does not constitute an “clean up”. It also does not apply to fuel, fire extinguishing systems, drive line parts (not including fluids), wheels, tires, brake systems, etc. An oil/liquid cleanup resulting from a crash will not result in a penalty unless the accident was a result of depositing oil/liquids on the track.
20. Rain delays are not considered a rainout. Until a decision has been made by management that an event has been cancelled or called, everyone must consider themselves on rain delay and not a cancellation... no credits will be given until this decision has been made. At that time, the policy below stands.
No tech card rainchecks will be given if at least 1time trial/qualifying session is provided or the first round of eliminations is completed for your class entered. Points will be awarded according to completed elimination rounds in each class. If 1-time trial/qualifier or round one is not completed a tech card credit minus a $10.00 handling fee will be given, this credit will be valid for 1 year.
Test n tune tech cards will be given a rain check unless the racer has entered the burnout box at any time during the event. Then the test and tune is considered complete at this time.
