All applicable regulations as they pertain to the vehicle shall be enforced. Any runs made without applicable chassis or driver certifications shall be disallowed.

Weight boxes are permitted, but No more than two are allowed to hold small items such as shot bags, lead bars, etc.  Ballast mounts must be sufficiently strong to support the weight of the ballast.  The ballast or boxes must be securely mounted to the frame with at least two bolts 1/2? in diameter. NDRL reserves the right to determine what ballast or mounting is illegal do to its structural design, appearance or excessive weight that could create a safety hazard.

BATTERIES
All batteries must be securely mounted. Batteries in passenger compartment are not allowed. For hatchback vehicles or for vehicles with inside material removed exposing trunk area, a firewall of .024" thick steel or .032" aluminum must be installed to seal battery area off from driver area. Relocated batteries must be fastened using a minimum of 2 bolts, 3/8" in diameter. No J-Bolts are allowed. Vehicles are limited to a maximum of two automotive batteries or 150 lbs. total combined weight.

The off position must be clearly identified with the word "OFF".   NOTE: If using a push/pull type switch, the off position must be pushed to turn off and labeled "PUSH OFF".

COOLING SYSTEM

Vehicles with hide a way headlights must have a working headlight behind the headlight door. A fog lamp may be substituted in place of the headlamp at the tech official's discretion.

QUALIFYING/TIME RUNS
Each class will have two qualifying runs.  Qualifying positions will be determined on luck of the draw pairing. Once a competitor has received a qualifying position and lane no changes may be made, except by an official from NDRL. If any competitor fails to qualify in the assigned position, then that round of qualifying will be forfeited. All classes will qualify and eliminate on a pro-ladder. During eliminations, the number one qualifier will be given the option to run where he/she chooses in the ladder. Otherwise, we will start with the slowest qualified pairing and continue to the quickest. Lane choice will be given to the quickest qualifier during first round. Subsequent to that, it will be awarded to the previous rounds quickest E.T. All vehicles must weigh at the conclusion of each run during qualifying and eliminations.

LANE CHOICE
In the Professional and Sportsman categories, lane choice is determined by elapsed times or closest to index. The rider with the better qualifying position (E.T.) gets first-round lane choice, and in subsequent rounds, lane choice goes to the rider with the lowest E.T. in the previous round or closest to the index without breaking out for index classes. ET lane choice is determined by drawing of chips until riders are placed on the ladder, at which point lane choice has been determined by the rider running closest to previous run’s dial-in.

BYE RUNS
All entries must take the tree under power.

COMPETITION NUMBERS
Each vehicle entered into competition must have their racer number affixed to the windshield and on each side window.  All participants will be required to run the same car number throughout the racing season.  More information concerning this issue will be made available when the point system begins (TBA).

ENGINE RESTART
If a car looses fire after the burn out, they will be allowed a maximum of 30 seconds to restart and pre-stage.  If they do not pre-stage after 30 seconds, the other car will be sent on a single run.

STARTING SYSTEM & STAGING
Auto Start will be used at all tracks where available.
 

• All heads-up classes will utilize the three amber “Pro Start” Christmas Tree.  In the Pro Tree system, all amber lights are activated simultaneously, with a four-tenths second delay to green.
• Both racers must have their pre-stage lights activated before either move into the stage beams.
• A reasonable amount of time will be permitted for riders to stage.  The Official Starter or Autostart feature of the timing system will determine the time limit.
• Failure to stage upon the Starter’s request is grounds for disqualification. After proper staging one cannot re-stage. Forward motion must be used when going from pre-stage to staged position.  
• Any racer leaving the starting line before the start system is activated, or is instructed to leave the starting line by the Official Starter, will have their time voided for the run. 
• During eliminations, if both racers leave the line before the starting system is activated, both would be disqualified.  A racer on a single run would advance.
• Deep staging is allowed at the risk of the driver.

DISQUALIFICATION
Disqualification will be determined on a first or worst offence. The first competitor to commit a foul is eliminated. If a competitor red lights and the opponent crosses the centerline, then the competitor's opponent will be disqualified and the competitor who red lighted will be re-instated. Any vehicle whose tire completely passes beyond the center yellow line will be disqualified.

RECORDS
Qualifying, eliminations and final round runs will be counted toward E.T. records.  The record will be awarded to the driver who set the record at the end of an event.  In the case of a tie, the record will go to the driver who produced the fastest speed on the record setting run.  If a tie still exists, the driver who set the back-up record first within one percent at the same event will be awarded the record. In the event that two runs exceed the record, the latter run being faster will be used to back the first and the first shall be established as the record.  All records must be backed-up within one percent.

TOW VEHICLES
A valid driver’s license is required to operate any type of tow vehicle. All entries are allowed to tow to the staging lanes and pits.  ATV’s, Golf carts, Scooters and motorcycles are allowed.  Golf carts are the only tow vehicles allowed to have more than one person on the vehicle (3 max).  Posted pit speeds must be obeyed at all times.  If pit speed is not posted a maximum of 10 mph is what will be allowed.

Participants at NDRL events are expected, at all times, to conduct themselves in a professional and non-disruptive manner.  Any participants who violate the following participant code of conduct below will be subject to immediate removal from the event in addition to further disciplinary action.
