SIGNS, FLAGS & LIGHTS

“Oversize Load” signs are required for all loads moving under a permit. Red flags must be attached to each side of the widest part of the load and to the rear of all overlength loads. If an overhang is over legal limits, the end of an overhanging object must be flagged and a lamp shall be placed at the end of the load to make the overhang more visible during periods of hazy daylight. Overweight-only loads need “Oversize Load” signs when running in daylight. They are not necessary if running at night.
