CONTEST PROCEDURE:

General Rules: For Members and Non-Members:

Any contestant under 18 must have written consent from parent or guardian and prior approval from EPIC Pulling Series. Minimum age for competition is 16 years old with a valid driving license.
Contestants may not be allowed to participate for emotional or physical reasons. (i.e. including drinking or illness, etc.)
Only driver will be allowed in vehicle when it is being towed or driven. No riders on tow tractors or track equipment will be permitted.
Driver must be in driver’s seat while engine is running.
Vehicle must be in neutral or park while hooking to or unhooking from sled. Driver is recommended to raise hands while hooking or unhooking from sled.
Any driver or crew member found under the influence of drugs or using intoxicating agents in the track area will be disqualified. Area is defined as 30 feet within the track.
No videotaping is allowed closer than 30 feet from track or unless directed by head track official.
The first puller in the class will have the option of test puller. The test puller may accept their distance, come immediately back, drop five positions, or last. Track official must be informed of decision before leaving the track.
For mechanical reasons only, a puller may drop to last position in the class. This is allowed by track judge’s discretion. Safety equipment does not qualify for a mechanical problem.
Once track is ready and competition director signals competitor to the track, competitor will have four (4) minutes to make a measurable distance under green flag conditions. Puller receives two attempts to move the sled. If on first attempt, driver lifts off the throttle before 100’ the puller will return to the start line and receive their second and final attempt.
Puller may spot the sled anywhere in bounds and behind starting line if they wish. This must be done while sled is coming back to the starting line from the previous pull. Only one sled spotting is allowed.
All pulls will start with a tight chain. No jerking of sled is permitted. Excessive jerking of the sled will result in disqualification.
Excessive loss of liquid will result in disqualification if vehicle is under the green flag. Excessive is defined as any steady or intermittent stream equal to a spot on the track of ten (10) inches in diameter. Major mechanical breakage will not result in disqualification.
Pulling will be considered over when forward motion stops. Puller must stop immediately when flagged or be disqualified.
Any re-pull caused by contest malfunction, the puller may drop five (5) positions or drop to the end of the class. Puller may not move any weight or competitor will be disqualified.
All pulls will be measured by laser, GPS, or measured to the nearest inch by hand. In the event of a tie, for first place only a Pull Off will incur at the conclusion of the class.
When possible, all contestants must drive off and on the track. Tow starting will be done at last resort and under track judge’s discretion.
All pulling vehicles must pass a tech inspection and meet all safety requirements before they can pull at any event. The EPIC Pulling Series has the right to inspect any vehicle at any time. Refusal will result in disqualification.
No competitor may compete in a class, once the class has started, if arriving late.
Any truck making a full pull must have the same driver in an event of a pull off. Driver will only have one attempt during pull off to move sled.
While vehicle is at scales weighing, only one crew person allowed in scale-masters area.
Judges’ decisions are final. There is no appeal process. Disagreement will result in disqualification.

RULES OF DISQUALIFICATION:

Out of bounds, this is described as any part of the pulling vehicle touching the white boundary line.
Loss of weight under green flag.
Loss or failure of safety equipment or equipment belonging to vehicle under the green flag.
Loss of excessive liquid
Unsportsmanlike Conduct - Any competitor or crew member displaying unsportsmanlike conduct at any EPIC Pulling Series sanctioned events whether verbal or physical will be reason for that team’s loss of points and purse for the event where the actions take place. Any second offence after official notification in writing by EPIC Pulling Series will be cause for the competitor and team suspension for a up to one year and ten days from date of infraction.
Illegal equipment.
Leaving the starting line under red flag.

Points:

The following is the EPIC Pulling Series point systems:

45-point system:

1st - 45pt 6th - 30pt

2nd - 42pt 7th - 27pt

3rd - 39pt 8th - 24pt

4th - 36pt 9th - 21pt

5th - 33pt 10th - 18pt

All remaining competitors will receive 15 points, respectively, if a measurable distance has been made under green flag conditions. If competitor does not make a measurable distance, competitor will receive 10 points.
Disqualifications will receive last place points and no money in their class.
Eligibility for any points at any event depends on competitor paying entry fee and passing tech inspection. It is competitor’s responsibility to have a tech official inspect their vehicle.
If a truck breaks before hooking, it will receive 10 points. If a truck hooks to the sled and attempts to move, but breaks, it will receive last place points and last place monies.
If at the end of the season, points’ races result in a tie, the highest amount of first place finishes will determine an overall points winner. If a tie occurs, the next place position (2nd, 3rd, and so on) will be calculated until a winner is determined.
