Rules / Car Construction
Please read all these rules completely, since failure to comply with all rules will result in disqualification, as judged by the Pack 707 Race Committee. These rules are the official Cub Scout (BSA) Pinewood Derby Rules, and have been adopted by our Pack so that winners may advance to District championships.
