Crimes: intoxication or impairment; careless or negligent operation of vehicle as civil infraction; modify. Amends sec. 626b of 1949 PA 300 (MCL 257.626b).

HB 4188 amends Michigan's Vehicle Code to clarify that operating a vehicle "in a careless or negligent manner likely to endanger any person or property, but without wantonness or recklessness" would be classified as a civil infraction. This change directly affects drivers whose behavior meets this specific standard - non-reckless, careless driving - by treating it as a civil matter rather than a criminal offense. The bill modifies Section 626b of the Michigan Vehicle Code (MCL 257.626b) to explicitly exclude cases involving "wantonness or recklessness," which would remain subject to more severe penalties. The amendment is procedural and aims to refine the legal definition of the infraction. The bill was introduced on March 6, 2025, and referred to the Judiciary Committee.
