Subtitle 4 - HIGHWAYS DIVISION
Chapter 104 - THE MOVEMENT BY PERMIT OF OVERSIZE AND OVERWEIGHT VEHICLES ON STATE HIGHWAYS
Section 19-104-15 - Overwidth
Current through February, 2024
(a) Permits normally shall be issued for widths up to 14 feet provided:
(b) Permits may be issued to move a vehicle or combination of vehicles, empty or with load, 14 feet or wider, provided:
(c) All vehicles or loads exceeding 12 feet in width shall require an escort vehicle. However, this shall not preclude a requirement for an escort vehicle in certain areas for loads of lesser width or for an additional escort vehicle depending upon the character of the road and the traffic volume. In general, escort vehicle may be required for widths exceeding 10 feet on two-lane roads traversing mountain or winding coastal areas.
(d) The district engineer may require police escort when in his judgment such escort is necessary to ease the flow of traffic or for public safety.
(e) Each overwidth movement exceeding 12 feet in width shall have wood or metal panel 6 feet by 1 foot sign with 10 inch high black letters on yellow background painted with 1-1/4-inch stroke to read "WIDE LOAD." (Reflective sign shall be required for movements at night.) The sign shall be securely mounted to the front or rear of the carrier vehicle or the escort vehicle, as specified in the permit, in such a manner that the sign will be clearly visible by approaching motorists from the front or rear. The applicant shall insure that the sign does not obstruct the view of the driver and obscure required warning and safety devices such as lights, flags, reflectors, and rear view mirrors.
(f) Vehicles with width greater than nine feet, including load, may cross state highways at permissible locations (e.g., permitted access points, tractor crossings, intersections, etc.) without permits provided that the other limitations regarding length, height, projection, or weight are not exceeded. These vehicles, when involved in crossing only, are exempt from this chapter.
