Drop tests are required by Rule 9.2.4 and require that each buggy is tested before freerolls and after they race.
Drop tests, or "drops," take place on the sidewalk in front of the Skibo Gymnasium. The buggy is released from rest facing downhill toward the start lines. The buggy must roll freely down the sidewalk for 30 feet before the driver is signaled to brake. The buggy must stop with its nose less than 15 feet past the brake line. The driver is then told to release and reapply the brakes. If a buggy does not stop within the allotted 15 feet, or is unable to brake the second time, it can attempt to pass the drop test one more time before being deemed unfit to roll and needing to successfully complete another braking capability test before rolling.
