PULLING PROCEDURES:
COMPETITION NUMBERS: All vehicles are required to display their assigned competition/exhibition numbers
(in the upper left / right hand corner of the windshield, depending on direction of the pull) at all pulling events.
Competition numbers are issued to ALL pullers only and are assigned to one truck only.
Registration for all classes ends 30 minutes before the scheduled start of pulling. Unless other arrangements
have been made with the Pull Director / Promoter on day of event.
DRIVERS MEETING: All drivers must attend the drivers’ meeting. The meeting is typically scheduled 15 minutes
before the pull starts. Failure to attend the drivers’ meeting may result in disqualification and loss of entry fees for
that event. It is the driver’s responsibility to find out when and where the meeting is to be held.
STAGING: Once a vehicle reaches the front of the staging area for a run, it must be prepared to fire and pull. To be a
legitimate pull winner, a contestant’s vehicle must self-start. Push starting or push-staging any vehicle is prohibited.
Staging must be done under the vehicles own engine power. Hoods must be closed and securely latched prior to
hooking to the sled.
PULLS: All events with pulls scheduled over two days will consist of two separate pulls. The order for the each pull
will be determined by drawing random numbers. To constitute an official pull, a truck must self-start, self-stage, hook
and attempt to pull. For all classes of competition, an individual truck cannot be used for multiple entries. Vehicles
must remain in one class with one registered driver for the duration of the event. All pullers will have two chances to
move the sled if they let off the throttle before the 100 foot marker. The truck and sled may coast past the marker. In
the event of a legitimate mechanical breakdown, the puller will be allowed to unhook from the sled, pull off to the
side and fix the malfunction, upon approval by the starting / flagger or Competition Director/Promoter. The truck
may not return to the pits. The pull will continue during the repair. If it is the last truck in the class, the puller will
have five minutes to hook from the time the sled is ready. If a truck has a legitimate mechanical failure in the staging
line, the puller may drop back in the order until it is repaired. The truck may not return to the pits. If it is, or becomes,
the last truck in the class, the puller will have five minutes to pull from the time the sled is ready. Faking a
21
mechanical failure in order to obtain a better position in line will result in disqualification. The Competition
Director/Promoter decision is final. The track will be re-dressed after every truck pulls, or as the weather dictates.
DISQUALIFICATIONS: Any portion of any wheel crossing or touching the boundary lines while pulling will result
in disqualification. Disregard for any flagman or official is grounds for disqualification. Any driver and/or pit-crew
member found to be under the influence of alcoholic beverages or drugs, regardless of amount, will be ejected from
the event. Such a condition is cause for suspension, fine, and/or revocation of competition privileges.
Any loss of ballast while under the green flag will result in disqualification. Extending any portion of the driver’s
body outside the driver compartment while the vehicle is hooked to the sled is grounds for disqualification.
REQUIRED CREDENTIALS: All pullers must have a valid state driver’s license endorsement.
PROTESTS: Any protests must be made before the class/division is done pulling and the person protesting must be
pulling in the same division & weight class. PROTEST MUST BE SUBMITTED IN WRITING. And Within 30
minutes of last vehicle pulling in that class, Only one item per protest and a FEE of $300.00 will be required.
Protestor’s TRUCK will be checked first and fee will be returned to protestor if protested truck fails inspection. If
protested truck passes inspection, $200.00 will go to owner and $100.00 to Promoter/Tech official. Promoter / Tech
Official will have the final say of any disputes or placing’s. THIS GOES FOR ALL TRUCK/TRACTOR CLASSES
