Status: in_force

(1) WIDTH LIMITATION. — The total outside width of any vehicle or the load thereon may not exceed 102 inches, exclusive of safety devices determined by the department to be necessary for the safe and efficient operation of motor vehicles. The use of public roads that do not have at least one through lane of 12 feet or more in width in each direction, and the use of public roads deemed unsafe for wider vehicles on the basis of safety and engineering analyses, by vehicles exceeding 96 inches in width may be restricted by the Department of Transportation or by local officials for streets and roads under their respective jurisdictions. The total outside width of a noncommercial travel trailer, camping trailer, truck camper, motor home, or private motor coach as defined in s. 320.01 may be more than 102 inches if: (a) The excess width is attributable to appurtenances that do not extend beyond the exterior rearview mirrors installed on the motor home by the manufacturer or the exterior rearview mirrors of the tow vehicle; and (b) The exterior rearview mirrors only extend the distance necessary to provide the appropriate field of view for the vehicle before the appurtenances are attached.

(2) HEIGHT LIMITATION. — No vehicle may exceed a height of 13 feet 6 inches, inclusive of load carried thereon. However, an automobile transporter may measure a height not to exceed 14 feet, inclusive of the load carried thereon.

(3) LENGTH LIMITATION. — Except as otherwise provided in this section, length limitations apply solely to a semitrailer or trailer, and not to a truck tractor or to the overall length of a combination of vehicles. No combination of commercial motor vehicles coupled together and operating on the public roads may consist of more than one truck tractor and two trailing units. Unless otherwise specifically provided for in this section, a combination of vehicles not qualifying as commercial motor vehicles may consist of no more than two units coupled together; such nonqualifying combination of vehicles may not exceed a total length of 65 feet, inclusive of the load carried thereon, but exclusive of safety and energy conservation devices approved by the department for use on vehicles using public roads. Notwithstanding any other provision of this section, a truck tractor-semitrailer combination engaged in the transportation of automobiles or boats may transport motor vehicles or boats on part of the power unit; and, except as may otherwise be mandated under federal law, an automobile or boat transporter semitrailer may not exceed 50 feet in length, exclusive of the load; however, the load may extend up to an additional 6 feet beyond the rear of the trailer. The 50-feet length limitation does not apply to non-stinger-steered automobile or boat transporters that are 65 feet or less in overall length, exclusive of the load carried thereon, to stinger-steered boat transporters that are 75 feet or less in overall length, exclusive of the load carried thereon, or to stinger-steered automobile transporters that are 80 feet or less in overall length, exclusive of the load carried thereon. For purposes of this subsection, a “stinger-steered automobile or boat transporter” is an automobile or boat transporter configured as a semitrailer combination wherein the fifth wheel is located on a drop frame located behind and below the rearmost axle of the power unit. Automobile transporters operating under this subsection may backhaul cargo or general freight if the weight of such cargo or freight does not exceed the limits imposed under s. 316.535. Notwithstanding paragraphs (a) and (b), any straight truck or truck tractor-semitrailer combination engaged in the transportation of horticultural trees may allow the load to extend up to an additional 10 feet beyond the rear of the vehicle, provided the trees are resting against a retaining bar mounted above the truck bed so that the root balls of the trees rest on the floor and to the front of the truck bed and the tops of the trees extend up over and to the rear of the truck bed, and provided the overhanging portion of the load is covered with protective fabric. (a) Straight trucks. — A straight truck may not exceed a length of 40 feet in extreme overall dimension, exclusive of safety and energy conservation devices approved by the department for use on vehicles using public roads. A straight truck may attach a forklift to the rear of the cargo bed, provided the overall combined length of the vehicle and the forklift does not exceed 50 feet. Except as otherwise provided in this section, a straight truck may tow no more than one trailer, and the overall length of the truck-trailer combination may not exceed 68 feet, including the load thereon. Notwithstanding any other provisions of this section, a truck-trailer combination engaged in the transportation of boats, or boat trailers whose design dictates a front-to-rear stacking method may not exceed the length limitations of this paragraph exclusive of the load; however, the load may extend up to an additional 6 feet beyond the rear of the trailer.
