State Highway Administration - Urban Core and Urban Center Traffic Control Devices - No Turn on Red

HB 381 requires Maryland's State Highway Administration to install traffic control devices prohibiting right turns on red at specific intersections on state highways in urban cores and urban centers by July 1, 2029. It directly affects drivers at these intersections by changing the default rule from "turns on red are permitted unless prohibited" to "turns on red are prohibited unless allowed by a sign." The bill amends existing law to mandate these devices while allowing exceptions if installation would significantly impair public safety. The law takes effect October 1, 2026, with full implementation required by 2029.
