In Idaho, super loads are defined as any load that exceeds 16 feet wide, 16 feet high, or 120 feet long. Weight restrictions are determined by a weight chart system. See the Idaho Transportation Department website for more details.
A schematic drawing showing axle placement, distance between axles and distribution of gross weight on axles may be required for all super loads.
Any load over 18 feet wide, 16 feet high, 120 feet long, must be approved by each District through which the load is travelling.
