During the race:
If, during a race, a car leaves the track without interfering with its opponent, it shall be considered to have ended its heat at that point.
If a car leaves its lane, at his sole discretion, the track chairman may inspect the track and, if a track fault is found which probably caused the initial violation, the track chairman may order the race to be rerun after the track is repaired.
If, during a race, no car reaches the finish line on the track, the car which went the farthest in its lane shall be declared as the heat winner.
If, during a race, a car leaves its lane and, in so doing, interferes with another racer, then the car at fault shall be declared to have lost the race heat.
Construction of ALL entries MUST have begun AFTER last year's races.
Only one car may be registered by any person in the Pinewood Derby.
Only dry lubricants such as graphite or powdered teflon "white lube" will be allowed for lubricating the wheels. Lubricants may not foul the track.
Only one lubrication is allowed before the beginning of the first race and then once again before the beginning of the first race of the semi-finals and finals.
Details such as the steering wheel, driver, decals, painting, and interior detail are permissible as long as these details do not exceed the maximum length, width, and weight specifications.
