Pinewood Derby Rules

Pack 621 Pinewood Derby Rules

  • These rules have been researched and set forth by Cubmaster Daniel Eosco, March 6th, 2016
  • Note that all Pinewood Derby rules are set at the local race level. There are no Official Pinewood Derby Rules that are used nationwide. For our Pack we will use this simple, clear set of rules. Other Packs may have elaborate rules. Be sure to read and abide by the rules for our local race.
  • For our Cub Scout Pack races, we inspected each car at weigh-in on race day.
  • We will weight each car with the "official scale" and turn back any car that exceeded 5.0 oz. We will then perform a quick visual inspection of each car against the following inspection points:

Car Dimension Rules

  • The overall length of the car shall not exceed 7 inches.
  • The overall width of the car shall not exceed 2 ¾ inches.
  • The car must have 1 ¾” clearance between the wheels.
  • The car must have 3/8” clearance underneath the body so it does not rub on the track.

Derby Car Weight Rules

  • The car shall not exceed 5.0 ounces.
  • The official race scale that is used at car check-in shall be considered final.

Car Modifications Not Allowed

  • The official pine wood block must be used. The block may be shaped in any way that is desired.
  • Official BSA wheels must be used. The wheels may not be cut, drilled, beveled or rounded. You may remove the seams and imperfections from the wheels.
  • The axles may be altered, polished and lubricated.

Other Pinewood Derby Race Rules

  • Once a car passes inspection and is entered into the race, only race committee members can touch it.
  • If the car loses a wheel, or is otherwise damaged, the racer shall have 5 minutes to make repairs.
  • Each car must pass inspection by the official inspection committee before it will be allowed to compete.
  • The Inspection Committee has the responsibility to disqualify those cars that do not meet these rules.
