SB 1078 Summary

• Changes language in Michigan Vehicle Code Section 642 from "shall" to "must" and from "when" to "if" for updated grammatical consistency throughout the statute.

• Allows any agency with jurisdiction over a roadway to designate HOV (high-occupancy vehicle) lanes, rather than limiting this authority to specific designations under 1951 PA 51.

• Expands exemptions from HOV lane restrictions to include motorcycles and allows agencies to determine additional vehicle classes exempt from HOV restrictions.

• Simplifies HOV lane marking requirements from "signs and pavement markings" to "traffic control devices" as the designation method.

• Clarifies lane usage rules for 3-lane roadways by specifying when center lanes may be used, including overtaking, left turns, and when officially designated for one-way traffic.
