4. No emblem shall be required on machinery or equipment pulled or attached to a farm tractor providing the machinery or equipment does not extend more than twelve feet to the rear of the tractor and permits a clear view of the emblem on the tractor by vehicles approaching from the rear.
5. Any person operating an animal-drawn vehicle on any public highway of this state may, in lieu of displaying the emblem required by subsections 1 and 2 of this section, equip the animal-drawn vehicle with reflective material complying with rules and regulations promulgated by the director of the department of public safety. The reflective material shall be visible from a distance of not less than five hundred feet to the rear when illuminated by the lower beams of vehicle headlights. Any rule or portion of a rule, as that term is defined in section 536.010, that is created under the authority delegated in this section shall become effective only if it complies with and is subject to all of the provisions of chapter 536 and, if applicable, section 536.028. This section and chapter 536 are nonseverable and if any of the powers vested with the general assembly pursuant to chapter 536 to review, to delay the effective date, or to disapprove and annul a rule are subsequently held unconstitutional, then the grant of rulemaking authority and any rule proposed or adopted after August 28, 2004, shall be invalid and void.
