General Rules

STANDARD RULES/REGULATIONS

Courtesy Staging will be STRICTLY enforced.
REMINDER: No Deep Staging in ANY class 


These rules are subject to change at any time. If there is any question, please check with the track manger, the tower or a track official for clarification. The current NHRA Rule Book mandates specific safety requirements for vehicles participating at all member tracks. Safety requirements specified in the current NHRA Rule Book for a specific class or ET will be in effect during Texas Diesel Madness event and take precedence over information contained here. Additionally, Big Country Race Way, and/or Abilene Diesel Performance representatives have the right to disqualify an entry if, in their opinion, the vehicle presents a potential risk for the driver, crew members, other racers, track personnel or spectators. The decision of track officials is final.


DISCLAIMER: The rules and/or regulations set forth herein are designed to provide for the orderly conduct of racing events and to establish minimum acceptable safety requirements for such events. These rules shall govern the condition of all 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. They 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.  


We are a family owned and operated facility - and we understand that folks like to enjoy the occasional adult beverage while enjoying their recreation. With that in mind - we would appreciate your adherence to the following regarding alcohol consumption on premises.

NO ALCOHOL PERMITTED IN THE STAGING LANES, NEAR FUEL DEPOT OR IN THE WINNER'S CIRCLE - NO EXCEPTIONS. ONE WARNING WILL BE ISSUED - THEN YOU WILL BE ASKED TO LEAVE. 


DRIVERS CAUGHT DRINKING ALCOHOLIC BEVERAGES OR USING ILLEGAL DRUGS WILL BE DISQUALIFIED. Each driver is responsible for the actions of their crew members. 


NO GLASS CONTAINERS ALLOWED ON THE PREMISES. Any adult beverages should be restricted to your pit, picnic area or the stands and MUST be in NON-GLASS CONTAINERS. 


Fighting, unsportsmanlike conduct, profane language, threatening a track official or other aggressive behavior targeted at any track official, racer or spectator will not be tolerated. Expulsion from the facility and other disciplinary action at the discretion of the track management may result. Each driver is responsible for the actions of their crew members.

For the 2019 season anyone running 7.00 or faster will be required to have a diaper or oil  containment system (pan) on their car. We are doing this to encourage safety and prevent injury. And it will save time with track clean up too. For less than $150.00 you can protect your  life and your car. Also, we will have them available in the bottom of the  tower.

STUTTER BOXES, TRACK LOCATORS (counters) & SIMILAR DEVICES ARE NOT ALLOWED. Use of such devices during any run will result in immediate disqualification and expulsion from the event. Entry fees WILL NOT be refunded. Only NHRA approved electronics and throttle controllers are allowed.  All installed SFI certified safety equipment must be up to date with current dates and numbers.  Refer to the NHRA rule book for equipment requirements based on your class and ET. 

HELMETS - PER NHRA 2015-2016 Amendments:

NOTE - ETs are expressed as 1/4 mile - conversion is as follows: 9.90 = 6.30, 10.00 = 6.40, 11.00 = 7.00, 12.00 = 7.50 and 14.00 = 8.60.SECTION 4A: SUPER PRO, PRO, SPORTSMAN, DRIVER:10, HELMET (Page  7) (10/26/2015)  For all 10.00 to 13.99 closed-bodied cars, either an open-face or a full-face Snell  M2005, M2010, M2015, K2005, SA2005, SA2010, SA2015, SFI 31.1/2005,  31.1/2010, 31.1/2015 or 41.1/2005 helmet with or without a shield is mandatory.  For all 10.00 and slower dune-buggy-type vehicles and all 10.00 to 13.99 openbodied  front-engine or rear-engine supercharged, turbocharged, nitrous, or  naturally aspirated cars, a full-face Snell M2005, M2010, M2015, K2005,  SA2005, or SA2010 or SA2015 helmet and shield mandatory (goggles  prohibited).  For all 9.99 and quicker closed-bodied cars, a full-face Snell M2005, M2010,  M2015, K2005, SA2005, or SA2010 or SA2015 helmet mandatory; shield  permitted (goggles prohibited). For all 9.99 and quicker open-bodied front-engine  or rear-engine supercharged, turbocharged, or nitrous cars, a full-face Snell  SA2005 or SA2010 or SA2015 helmet and shield mandatory (goggles  prohibited).  For all 9.99 or quicker open-bodied front-engine or rear-engine  naturally aspirated cars, a full-face Snell M2005, M2010, M2015, K2005,  SA2005, or SA2010 or SA2015 helmet and shield mandatory (goggles  prohibited). See General Regulations 10:7.

Report to tech as soon as possible after entering the facility. YOU WILL NOT BE ALLOWED TO STAGE IF YOU DO NOT HAVE A TECH STICKER. Basic requirements: Battery hold down, radiator overflow catch can, all lug nuts in place, remove wheel covers (do not race with hub caps or wheel covers in place), no fluids leaking from the vehicle. Refer to track specific safety requirement and the NHRA rule book for your class or ET.  

For all NHRA Sportsman and E.T. racers, a functional light must be visible from the rear of the car. This                                 eliminates all reference to night racing only, meaning a light must be functional at all times.CLEARLY mark your car number and dial-in on the PASSENGER SIDE of the WINDSHIELD and the PASSENGER SIDE DOOR glass in 4" to 8" tall numerals before you are called to the starting line. Your dial-in cannot be changed after the entry has left the head of staging. Be sure your dial-in is correct on the dial-in display before you stage. By staging you accept it, right OR wrong, with no dispute or appeal. Competitors will be called to the staging area BY CLASSES for time trials and elimination rounds. Run order and lane assignment during time trials will be made by the "Stager". Run order and lane           assignment will be determined by fastest ET prior round during elimination rounds. To avoid delays between classes, the next class to run may be called to a pre-stage area while the staged class is being run. DRIVERS SHALL REMAIN WITH THEIR VEHICLE AT ALL TIMES AFTER ENTERING THE STAGING LANES AND KEEP VEHICLES TIGHTLY GROUPED.  

Big Country Race Way Breakage/Buyback rule: In most cases, we allow drivers with broken cars to buy back for a round if they are eligible for the buyback and their race vehicle cannot make the staging call for that round. HOWEVER - the driver MUST make take the tree that round in some vehicle with their car/competition number on the vehicle, no exceptions.  You must dial at least the minimum for the class - if there is a minimum- and no slower.  This minimum dial also applies to breakage in later rounds - you may stage your tow vehicle, but you must dial at least the class minimum. 


NO DEEP STAGING. If you turn off either the "pre-stage" or the "stage" light after your opponent has staged you are disqualified.  If you turn out the pre-stage bulb and the tree starts down, the computer will automatically red light your lane. Once three bulbs are lit (two pre-stage and one stage), you have 10 seconds to complete the staging procedure. 


Courtesy staging is enforced. If you light the pre-stage light first, you must wait for your opponent to light their pre stage light. If you do not, you will made to  back out and re-stage. 


Loss of ANY fluid may result in disqualification at the discretion of track officials. 


If you "break out" (run quicker than your dial-in) you lose, unless your opponent breaks out also. Then the vehicle breaking out the least is declared the winner in keeping with the "First or Worse" rule. If both break out by the exact same amount, the driver crossing the finish line first wins. 


You are disqualified if you "red light" or if you touch or cross the track centerline with any tire during a run. In cases of two (2) infractions on the same run, the "FIRST OR WORSE" rule will be invoked; for example, a vehicle crossing the centerline loses even if this was the second infraction. Centerline violations must be witnessed by a track official. 


HARD BRAKING WHICH CAUSES ANY TIRE TO SKID at ANY point during ANY run will result in disqualification at the discretion of the starter.  


A "BYE RUN" is when you have no opponent in staging. You can get only one (1) Bye Run in eliminations per race day. It is okay to breakout or red light on a Bye Run, or you can choose to not run through at all. A "COMPETITION BYE" is when your opponent could not pull to the line within the allotted time after being directed to do so by the Stager or Starter. Contestants can get more than one Competition Bye, but only one (1) Bye Run is allowed per race day. 


Long pants, shirt, shoes are required for all drivers in all classes, unless a fire suit is required. No shorts allowed in any class period.  


When qualifying for a qualified field, you must qualify during scheduled qualifying runs for that event.


Top ET (BOX) is allowed to one  burn out across the starting line per round. 


Pro Footbrake - open wheel cars and cars that are faster than 6.00 (1/8 mile) are allowed  one burn out across the starting line per round.


No two drivers may enter the same car in the same class. 


MAXIMUM TWO CREW MEMBERS are allowed on the starting line behind the starter per car. Crew member MUST be at least 16 years of age.  


Drivers in all classes must have a valid driver's license and be at least 16 years of age. 


Speed limit in the pits is 10 MPH. NO vehicle testing of any type. NO BURN OUTS. Bicycles, small motorcycles and 3 & 4 wheelers may be used for transportation in the facility. Persons operating these vehicles must be at least 16 years of age and have a valid driver's license. Improper use of these vehicles may result in expulsion from the facility and forfeiture of entry fees. 


No work may be done under any vehicle supported only by a jack.  Additional safety devices such as jack stands are mandatory in order to provide extra safety. Any vehicle jacked up with it's engine running must have jack stands in place and a licensed driver or rider in the driver's seat. Jack stands must have a board or other load spreading material underneath. Same with trailer jacks.


PROTESTS: Contestant protests must be submitted to the TRACK MANAGER before the final round of eliminations and/or before protested competitor has left the facility. To file a protest, the filer/competitor must be an owner or driver of a car that is entered in the same eliminator bracket as the car or driver protested. Protests will be submitted to the TRACK MANAGER ONLY. Protest fees will be submitted with the protest or the protest will not be accepted. Protest fees will be forfeited to the car owner if the protested car is determined to be legal for it's class. If the protested car is determined to be illegal for the class, the protest fee will be refunded. Official’s protests may be entered at any time during the event at no charge by the track officials. Protested cars will be notified at the timing shack or met on return by a track official and will proceed directly to a designated holding area for examination - car may not return to it's pit space first. The protest fee is $50
