Loads exceeding these dimensions are Super Loads.

Movements over 16′ high will not usually be permitted, and would require a letter of necessity describing the load and why it needed to go through TN to possibly get a permit.

MISCELLANEOUS: Bulldozer blades or loads with protruding sharp objects shall be loaded with the blade or protruding sharp object to the rear of the hauling equipment when the blade exceeds 10’6” in width. No permits will be issued for blades or protruding sharp objects creating width in excess of 13’6″. Combination loads cannot be permitted for two overdimensions on two different pieces (example: cannot permit for a load with overwidth dozer and overheight backhoe on same load).
SIGNS, FLAGS & LIGHTS: All movements exceeding 10′ in width and/or 75′ in length require “Oversize Load” at front and rear. Loads over 75’ overall length but not exceeding 85’ require a rotating or strobe type amber light on the end of the load. Red flags are required on overwidth loads front and rear, and top and bottom each side where load is widest (or at the widest point if it is between the top and bottom). Red flags must be placed at the extreme rear end of overlength loads or when there is over 4′ rear overhang. No sign or flag requirements are listed for overheight only loads. For overweight-only loads, you still need Oversize Load signs according to a scale officer, but the rules and regulations do not specify this.
