(1) The state department of transportation and the local authorities are authorized to reserve all or any portion of any highway under their respective jurisdictions, including any designated lane or ramp, for the exclusive or preferential use of one or more of the following: (a) Public transportation vehicles; (b) motorcycles; (c) private motor vehicles carrying no fewer than a specified number of passengers; or (d) the following private transportation provider vehicles if the vehicle has the capacity to carry eight or more passengers, regardless of the number of passengers in the vehicle, and if such use does not interfere with the efficiency, reliability, and safety of public transportation operations: (i) Auto transportation company vehicles regulated under chapter
81.68 RCW; (ii) passenger charter carrier vehicles regulated under chapter
81.70 RCW, except marked or unmarked stretch limousines and stretch sport utility vehicles as defined under department of licensing rules; (iii) private nonprofit transportation provider vehicles regulated under chapter
81.66 RCW; and (iv) private employer transportation service vehicles, when such limitation will increase the efficient utilization of the highway or will aid in the conservation of energy resources.
(2) Any transit-only lanes that allow other vehicles to access abutting businesses that are authorized pursuant to subsection (1) of this section may not be authorized for the use of private transportation provider vehicles as described under subsection (1) of this section.
(3) The state department of transportation and the local authorities authorized to reserve all or any portion of any highway under their respective jurisdictions, for exclusive or preferential use, may prohibit the use of a high occupancy vehicle lane by the following private transportation provider vehicles: (a) Auto transportation company vehicles regulated under chapter
81.68 RCW; (b) passenger charter carrier vehicles regulated under chapter
81.70 RCW, and marked or unmarked limousines and stretch sport utility vehicles as defined under department of licensing rules; (c) private nonprofit transportation provider vehicles regulated under chapter
81.66 RCW; and (d) private employer transportation service vehicles, when the average transit speed in the high occupancy vehicle lane fails to meet department of transportation standards and falls below forty-five miles per hour at least ninety percent of the time during the peak hours, as determined by the department of transportation or the local authority, whichever operates the facility.
(4) Regulations authorizing such exclusive or preferential use of a highway facility may be declared to be effective at all times or at specified times of day or on specified days. Violation of a restriction of highway usage prescribed by the appropriate authority under this section is a traffic infraction.
(5) Local authorities are encouraged to establish a process for private transportation providers, as described under subsections (1) and (3) of this section, to apply for the use of public transportation facilities reserved for the exclusive or preferential use of public transportation vehicles. The application and review processes should be uniform and should provide for an expeditious response by the local authority. Whenever practicable, local authorities should enter into agreements with such private transportation providers to allow for the reasonable use of these facilities.
(6) For the purposes of this section, "private employer transportation service" means regularly scheduled, fixed-route transportation service that is similarly marked or identified to display the business name or logo on the driver and passenger sides of the vehicle, meets the annual certification requirements of the department of transportation, and is offered by an employer for the benefit of its employees.
