Pinewood Derby Rules

Pinewood Derby Rules

The Official BSA Pinewood Derby Rules for the Cub Scout Pinewood Derby are the rules that are in the box of the Official Grand Prix Pinewood Derby Kits handed out by the scout leader. It is important to understand that Cub Scout packs are not required to follow the exact Pine Wood Derby rules established by the BSA. Pinewood Derby rules may differ from one pack to another. So every derby car builder must get a copy of their particular pack’s rules and build accordingly.


It is important to read all rules before planning and building your Pinewood Derby car.

The Pinewood Derby is open to all Cub Scouts. Cars should be built by the Cub Scouts with some adult guidance and supervision. Any technical assistance should be fully explained to the Cub Scout so that he can use that knowledge on future projects. Because it is difficult to establish how much help was given in building the car, some Packs have a separate Pinewood Derby Race for adults. This is usually called the Open Class.

I. Wheel bearings, washers, and bushings are prohibited.

VI. The car must be free-wheeling, with no starting devices. 
VII. Each car must pass inspection by the official inspection committee before it may compete. If, at registration., a car does not pass inspection, the owner will be informed of the reason for failure, and will be given time within the official weigh-in time period to make the adjustment. After final approval, cars will not be re-inspected unless the car is damaged in handling or in a race.
