Inspection. Each car must pass inspection by the Official Race Committee before it may compete. If a car fails to meet the rules, the Cub will be told what problems exist and may change the car to meet the rules. Decisions of the committee are final. We will have some tools and spare parts available for Cubs who need to make last-minute adjustments.
Good Sportsmanship! Anyone not displaying good sportsmanship and good behavior may be asked to leave.
If a car jumps the track or interferes with another car, the heat will be rerun. If it happens again, it'll be eliminated from that heat.
If a car breaks down or loses a wheel, the owner will be given 5 minutes to perform repairs and the heat will be rerun. If it breaks down a second time or cannot be repaired within 5 minutes, it's eliminated from that heat.
If a car is eliminated from a heat, it will be judged based on its other three times. A car that's eliminated more than once is eliminated from competition for speed.
Following inspection, a Cub may not handle his car again until after all 4 of his heats have been run except to perform repairs allowed in the event of a breakdown.
