K. Bye runs may be used when there is no opponent because of an uneven number of Scouts participating. A bye run is defined as a race with no opponent. Bye runs should be kept to a minimum, and no Scout should receive more than one bye. During a bye run, the Scout will be required to run his car down each of the two (2) lanes as if in an actual race. Race officials should assign multiple bye runs in the early levels of the race so that there will be no bye runs during the later levels.

L. Each heat will begin with the racing Scouts being called by name to the pit table. A Scout will have three (3) minutes to report before being disqualified. A Race official at the pit table will give the Cub Scout their car. The Scouts will then take the cars to the Race Starter for positioning on the track. Cars will switch lanes between the first and second race. If a third race is required, lane selection will be determined by a coin toss. Scouts will be given time to position themselves at the end of the track before the race starts. Scouts will return their cars to the starting gate between races. Upon completion of a heat, cars that have not been eliminated must be returned to the pit table.

Work must be done by the Scout with assistance from his parent or guardian. Race officials shall re-inspect any car that is serviced during the race. The Race officials may choose to continue with other race heats in order to avoid long delays in the race. The damaged car must be raced before the race proceeds to the next level of elimination.

N. In the final heat to determine 1st and 2nd place, the winner of the heat will be declared the overall winner regardless of his previous record. Car dynamics change in time and it may be possible for a car with one loss to beat a car with no losses. The Judges decision will be final.
