If you bring a stock truck off the road to pull you will not have to follow the safety rules as far as drive shaft, flywheel blanket, turbo cover, fuel shut offs or kill switch. You must provide current registration for 40 ton and be insured for hauling cargo. If you pull more than at one show  you will be required to install all safety equipment. Engine RPMS will be no more than 2500. NO EXCEPTIONS!


1)     Contest is limited to 2-wheel drive pneumatic tired pulling vehicle only.

2)     Contestants must pay dues and be a member in good standing before pulling.  Contestants under 16 must have written consent of parents or guardian and ECIPA Board of Directors.

3)     Pulling vehicle may enter only once in each class.

4)     Weight includes driver and all safety equipment.  Weights must be securely fastened.  Weight classes will have “zero” tolerance on weight UNLESS tech officials deem it necessary to change class weight for that event due to scale problems.  A competitive driver may ask winning pulling vehicle to re-weigh with a tolerance of 40 lbs over said class weight for BOTH protestor and protestee.  Weights may be certified at designated pulls.  Certified vehicles will display a sticker stating the drivers name, class, tire size, number and size of weights and amount of fuel in tank.  Sticker shall be clearly displayed on vehicle.  Certified weights would only be used when a scales is not available

5)     Each competitor will be allowed two attempts to make a measurable pull.

a)     An attempt is defined as moving the sled a measurable distance (one inch or more).

b)    On his/her first attempt, if competitor lets off on the throttle before going 100 feet, said competitor will get a second attempt, even if he went beyond the 100-foot mark.

c)     If no attempt is made to back off the throttle, no second attempt will be granted.

Note:  intent is for the driver not to slam on the brakes to stop before the 100 foot mark (or any time) but to come to a smooth, safe stop.

Cleaning of the track is up to the driver after a false start.   

6)     The first pulling vehicle has the option of turning down the first hook and immediately re-hooking or hooking in the 3rd major position only.  Limited Pro Stock classes will also have the option of re-hooking last in the class along with first or third positions.

7)     A pulling vehicle that does not go 100 feet and stays inbounds will be given a second chance except on pull-offs, where a pulling vehicle has only one attempt, no matter what distance pulled.  If a driver has trouble with his pulling vehicle on the first attempt, he may drop to last and has only one attempt.  If the sled operator re-sets the sled, the first puller may drop to last.

8)     No excessive jerking when starting or during pull.

9)     If pulling vehicle hitch breaks, the measurement will be taken at that point.

10)  Pulling vehicle pulling the farthest before stopping will be declared the winner of that class.  Distance will be measured from front center of sled if manual measuring is required.

11)  Pull is ended when forward motion stops or if pulling vehicle goes out of bounds.  Excessive digging will not be tolerated.

12)  Contest will be governed by judge or judges with all decisions final.  Safety will be foremost consideration.  Dangerous or unfair practices will be reason for disqualification.  Any of the following “a” thru “l” while HOOKED to the sled or under the green flag will be automatic disqualification:

a)     Driver does not remain seated.

b)    Loss of weights or brackets while still hooked to the sled.

c)     Loss of any safety equipment or shielding.

d)    Anything that falls off the pulling vehicle onto the track wile hooked to the sled is a disqualification.  The only exception to this would be parts that fall onto the track due to INTERNAL ENGINE OR DRIVELINE breakage—this would be internal OR external parts that fall off, but are due to internal engine or driveline failure.

e)     Anytime the pulling vehicle goes out of bounds.

f)     If puller or pulling team member shows unsportsmanlike like conduct:

First offense:  0 points will be awarded to the pulling vehicle for that class.

Second offense:  no points for both classes.

Third offense:  no points and no money for that day and barred from competition for a year and 1day.

g)    Driver must wear shirt, shoes and full length pants before competing in the pull.  Helmet and jacket are required.

h)     Severity of punishment is to be at the discretion of the ECIPA Board of Directors.  Although a major rules infraction such as illegal entry or flagrant violation of safety rule may cause contestant to be barred from competition for 1 year and 1 day from the date and/or withdrawal of accumulated points.

i)      The ECIPA Board of Directors resume the right to change, correct, delete or add any rules that might become necessary during any pulling season.

j)      On alcohol and drug use:  Any person (seen) drinking alcohol or using drugs on event grounds before operating any pulling vehicle:

First offense:  contestant does not compete that day—vehicle can with another driver.

Second offense: contestant does not compete that day and will get no points for that day.  Vehicle can compete with another driver.

Third offense: contestant does not compete that day and loss of points for that season and barred from competition for a year and 10 days.  Vehicle can compete with another driver.

k)     Excessive loss of fluids (coolant, motor oil, transmission oil, rear housing oil, water, etc.) while under the green flag.

l)      Driver leaves the seat while in the staging area or at any time the engine is running or is going to be started.

13)  A point system will be used with points awarded to all competing member pulling vehicle at all sanctioned events.  Pulling vehicles must hook to sled under own power and make an attempt to be eligible for points.  Points are awarded in this manner:

  5 points --- to hook to sled as stated above.

10 points --- first place

                                         9 points --- second place

                                         8 points --- third place

                                         7 points --- fourth place

                                       Down through 10 places 1 being 10th place.

        Last place points (for the event) will also be awarded to a pulling vehicle which is forced to scratch out of his/her second weight class due to breakage (points, no money).  The pulling vehicle doesn’t have to hook in class to be awarded these points (no money).  Any pulling vehicle disqualified will receive last place money and 5 hook points.  Last place money will also be awarded to a pulling vehicle which is forced to scratch out of his/her first weight class due to breakage (money, no points).  No points for a class will be awarded unless the entire class is completed.  In the event of a points race tie, the pulling vehicles involved will have all their footage distances (in that class) added up for the entire season; the most footage is the points winner for that particular class.

14)  Only one vote per pulling vehicle will be allowed when voting at meetings.

15)  Helmets must be on in staging area on deck and remain on until pulling vehicle is unhooked from the sled.  Chin straps must be used while wearing the helmet.

16)  No riders allowed on pulling vehicles – drivers only!

17)  All non-member pulling vehicles may be teched at any time at any pull.

18)  A floating finish line WILL be used.

19)  A pulling vehicle has a three minute time limit to get hooked to the sled when they are to pull.

20)  Turbo needs to be covered.

21)  Must be at event ½ hour before pull. Call if having trouble. 5 pts. docked if late.
