Traffic control: traffic regulation; authority to provide road closures in the interest of public safety; expand. Amends 1949 PA 300 (MCL 257.1 - 257.923) by adding sec. 606c.

HB 5156 amends Michigan's Vehicle Code to give local law enforcement agencies (like city police or county sheriffs) temporary authority to control traffic during emergencies or specific events. It allows officers or temporary devices to guide, direct, or stop traffic on any public road within their jurisdiction when necessary for public safety, including during large marches, parades, protests, terrorist attacks, or violent acts. The bill specifically expands existing traffic control powers to cover these scenarios without requiring prior court orders. This change directly affects how local police manage traffic during public gatherings or crises, aiming to enhance safety responses. The bill is currently in committee review after being introduced on October 29, 2025.
