MISCELLANEOUS: Blades and buckets which cannot be angled to not exceed 14 feet in width must be removed. A blade or bucket, if it is part of the original equipment being hauled, may be detached and hauled with the equipment without being considered a divisible load. Beams, poles, pipes, structural material don’t need permit up to 85 feet long, daylight only, on Interstates and designated roads.
Multiple pieces rule: NC does not allow or permit for multiple pieces on an overlength vehicle/load (over 60’ overall length) on “non-designated” highways. If you are hauling two farm tractors end-to-end and your overall length is 70 feet, we cannot get a NC permit except for Interstate and “designated” US routes (mainly 4-lane US highways). If your route is on other highways (including most US Highways), NC will not give us a permit unless we claim that it is for a single piece.
SIGNS, FLAGS & LIGHTS: “Oversize Load” signs are required at front and rear for all loads exceeding 10 feet wide. Flags are required on each corner and at the widest point of the load for all loads over 8’6″ wide, but the flags “…shall be so mounted as to not increase the overall width of the load.” Rear overhang in excess of 4 feet requires a flag, or at night a red or amber light visible for at least 200 feet.
