(a) Subject to the prior approval of the federal highway administration, the department is directed to incorporate the use of “RV friendly” markers on specific service signs for business establishments that cater to the needs of persons driving recreational vehicles. A business establishment that qualifies for participation in the specific service sign program and that also qualifies as RV friendly may request that an RV friendly marker be displayed immediately adjacent to the establishment's business logo sign on the appropriate background sign panel. For purposes of this section, the RV friendly marker to be displayed shall be a marker approved by the federal highway administration in the Manual on Uniform Traffic Control Devices.

(b) In accordance with the Uniform Administrative Procedures Act, compiled in title 4, chapter 5, and subject to the approval of the federal highway administration, the department shall promulgate rules and regulations that are necessary to implement this section, including the promulgation of rules and regulations setting forth the minimum requirements that business establishments must meet in order to qualify as RV friendly. The requirements shall include, but shall not be limited to, the availability at each qualifying business establishment of parking spaces, entrances, and exits in sufficient number and of sufficient size and dimensions to easily accommodate recreational vehicles, and the presence of appropriate overhang clearances at all facilities, if applicable.

(c) For the purposes of assisting the federal highway administration in considering the approval of an RV friendly marker for incorporation into the Manual on Uniform Traffic Control Devices, the department is directed to submit a request to the federal highway administration for permission to experiment with the use of an RV friendly marker on specific service signs in accordance with this section.
