Section 247.651 - State trunk line highway system; additions and deletions; operating license agreement with regional transit authority to operate public transit system; lane designation for high-occupancy vehicles(1) The state trunk line highway system of this state consists of all roads, streets, and highways, either located within or outside the limits of incorporated cities and villages, that are made state trunk line highways under the laws of this state. The director of the department may establish subordinate classifications or groupings of state trunk line highways as the department considers necessary or desirable for proper administration of the state trunk line highway system. Additions to and deletions from the state trunk line highway system may be made in the manner prescribed by law. All roads, streets, and highways included in the state trunk line highway system shall be known and may be referred to for all purposes as state trunk line highways.(2) The department or a local road agency may enter into an operating license agreement with a regional transit authority to operate a public transit system on the streets and highways of this state as provided for in state law enacted after January 1, 2012. As part of an operating license agreement, the department or local road agency may designate 1 or more lanes of a street or highway as a dedicated public transit lane. A dedicated public transit lane may be reserved for the exclusive use of public transit vehicles operated by a regional transit authority during periods determined by the department or the local road agency, except that a dedicated public transit lane must be made available at all times to emergency services vehicles. A lane designated and marked as a dedicated public transit lane by the department or a local road agency under an operating license agreement with a regional transit authority is subject to the same provisions as a high-occupancy vehicle lane under the Michigan vehicle code, 1949 PA 300, MCL 257.1 to 257.923.(3) Except as otherwise provided in this subsection, the department may designate a lane on a highway for the exclusive use of high-occupancy vehicles, during a period determined by the department, by filing a traffic control order and installing appropriate traffic control devices. This subsection applies only to lanes that are newly constructed using federal funds.(4) As used in this act: (a) "High-occupancy vehicle" means that term as defined in section 20b of the Michigan vehicle code, 1949 PA 300, MCL 257.20b.(b) "Traffic control devices" means that term as defined in section 70 of the Michigan vehicle code, 1949 PA 300, MCL 257.70.(c) "Traffic control order" means that term as defined in section 71 of the Michigan vehicle code, 1949 PA 300, MCL 257.71.Amended by 2023, Act 149,s 1, eff. 10/10/2023.Amended by 2012, Act 390,s 1, eff. 3/28/2013.Amended by 2008, Act 303,s 1, eff. 12/9/2008.1951, Act 51, Eff. 6/1/1951.
