Signs, Flags & Lights

Warning signs are mandatory for all oversized movements. For loads exceeding legal width, length, or rear overhang, “Oversize Load” signs must be displayed on the front of the vehicle and at the end of the load. Wide loads necessitate a minimum of two flags and up to six flags mounted at the widest points. Overlength vehicles or loads require one flag if the load is less than 2′ wide and two flags if it is greater than 2′ wide. For overhangs less than 2′, one flag is required, while overhangs greater than 2′ mandate two flags—one on each corner.
