  6. Back Road's Officials will be randomly inspecting tractors and trucks throughout the season. At each sanctioned Back Road's event, at least one tractor from the Improved Farm class will be selected at random for a full inspection. Any other random inspections will be announced the day of the pull. Back Road Pullers techs may inspect any vehicle, at any time.  
  7. If the vehicle inspection is refused by the driver(s), all points accumulated over the season will be forfeited and the driver and vehicle will be banned from all Back Road Pullers events until the vehicle has passed inspection.

In the event that any puller goes less than 100 ft you will be allowed to re-hook at that moment for a second attempt. If you are the first puller in the class this will also apply. Max 2 attempts for anyone. If you speed or go out of bounds, you may drop your first hook.

A registration fee of $100 must be paid along with a $100 membership fee from the driver of the vehicle during the class. Non-members pulling a registered vehicle will count as no points for the hook. 
  2. Points will be awarded to the vehicle itself. No points will be awarded to drivers. 
  3. Points will be awarded as follows: 1st place will be awarded 50 points, 2 points will be subtracted from each place until 12th place (28 points). From 13th place on back will be awarded 26 points.  Points will only be awarded upon completion of the class. 
  4. Only hooks that are full shows, that provide our recommended payouts will be counted as points hooks. All other pulls will still be Back Road Pullers sanctioned events and we encourage everyone to attend.
  5. The maximum number of points hook per season will be sixteen. 
  6. Cancelation of events: If a class or event is canceled due to weather or any other circumstances outside of the control of the event and Back Road Pullers, 20 points will be awarded to all pullers at the venue and checked in prior to cancelation.
  7. Rescheduling of events: All rescheduled events will be considered points pulls. Vehicles must make a hook at the re-scheduled event in order to receive points for it.
  8. Show up points: If a vehicle arrives to an event and is unable to pull due to mechanical problems or an emergency, the member will be awarded 25 points.  Final decisions to be made by the officers.
  9. Disqualification: Any track disqualifications during the pull including: over allowed RPM limit of the class, over allowed speed limit of the class, out of bounds. Speed limit classes are zero tolerance, any recorded speed over the allowed limit will be a disqualification.
  10. Points Championship: The bottom two hooks of each pullers recorded points hooks will be dropped at the end of the season. Points will then be decided from the points received after those hooks have been discarded. Pullers who have recorded points at every points hook in their class for the season will receive a bonus 10 points at the end of the year. Points will be recorded at each hook and displayed on the website, only at the end of the year will the bottom two hooks being dropped reflect on their points total. Missed events will count as one of the bottom hooks, allowing pullers to miss up to two hooks, and still have a shot at the championship.
