(d) (1) No person shall sell, lease, rent or operate any boat trailer, farm machinery or other machinery defined as a slow-moving vehicle in division (b) of this section, except those units designed to be completely mounted on a primary power unit, which is manufactured or assembled on or after April 1, 1966, unless the vehicle is equipped with a slow-moving vehicle emblem mounting device as specified in division (b) of this section.
(2) No person shall sell, lease, rent, or operate on a street or highway any unit of farm machinery that is designed by its manufacturer to operate at a speed greater than 25 miles per hour unless the unit displays a slow-moving vehicle emblem as specified in division (b) of this section and a speed identification symbol that meets the specifications contained in the American Society of Agricultural Engineers Standard ANSI/ASAE S584 JAN2005, Agricultural Equipment: Speed Identification Symbol (SIS).
(e) Any boat trailer, farm machinery or other machinery defined as a slow-moving vehicle in division (b) of this section, in addition to the use of the slow-moving vehicle emblem, and any unit of farm machinery that is designed by its manufacturer to operate at a speed greater than 25 miles per hour, in addition to the display of a speed identification symbol, may be equipped with a red flashing light that shall be visible from a distance of not less than 1,000 feet to the rear at all times specified in Ohio R.C. 4513.03 or a substantially equivalent municipal ordinance. When a double-faced light is used, it shall display amber light to the front and red light to the rear. In addition to the lights described in this division, farm machinery and motor vehicles escorting farm machinery may display a flashing, oscillating or rotating amber light, as permitted by Ohio R.C. 4513.17 or a substantially equivalent municipal ordinance, and also may display simultaneously flashing turn signals or warning lights, as permitted by that section.
(f) (1) Every animal-drawn vehicle upon a street or highway shall at all times be equipped in one of the following ways:
A. With a slow-moving vehicle emblem complying with division (b) of this section;
B. With alternate reflective material complying with rules adopted under division (f)(2) below;
C. With both a slow-moving vehicle emblem and alternate reflective material as specified in division (f)(2) below.
(2) Rules adopted by the Director of Public Safety, subject to Ohio R.C. Chapter 119, establishing standards and specifications for the position of mounting of the alternate reflective material authorized by this division, permit, as a minimum, the alternate reflective material to be black, gray, or silver in color. The alternate reflective material shall be mounted on the animal-drawn vehicle so as to be visible, at all times specified in Ohio R.C. 4513.03 or a substantially equivalent municipal ordinance, from a distance of not less than 500 feet to the rear when illuminated by the lawful lower beams of headlamps.
(g) (1) Every unit of farm machinery that is designed by its manufacturer to operate at a speed greater than 25 miles per hour shall display a slow-moving vehicle emblem and a speed identification symbol that meets the specifications contained in the American Society of Agricultural Engineers Standard ANSI/ASAE S584 JAN2005, Agricultural Equipment: Speed Identification Symbol (SIS) when the unit is operated upon a street or highway, irrespective of the speed at which the unit is operated on the street or highway. The speed identification symbol shall indicate the maximum speed in miles per hour at which the unit of farm machinery is designed by its manufacturer to operate. The display of the speed identification symbol shall be in accordance with the standard prescribed in this division.
(2) If an agricultural tractor that is designed by its manufacturer to operate at a speed greater than 25 miles per hour is being operated on a street or highway at a speed greater than 25 miles per hour and is towing, pulling, or otherwise drawing a unit of farm machinery, the unit of farm machinery shall display a slow-moving vehicle emblem and a speed identification symbol that is the same as the speed identification symbol that is displayed on the agricultural tractor.
(h) When an agricultural tractor that is designed by its manufacturer to operate at a speed greater than 25 miles per hour is being operated on a street or highway at a speed greater than 25 miles per hour, the operator shall possess some documentation published or provided by the manufacturer indicating the maximum speed in miles per hour at which the manufacturer designed the agricultural tractor to operate.
