Crimes: assaultive; assault or battery of certain vehicle operators and employees; prohibit under certain circumstances, and provide for penalties. Amends 1931 PA 328 (MCL 750.1 - 750.568) by adding sec. 81g.

This bill creates new criminal penalties for assaulting or battering public transit operators, including bus drivers, train conductors, and streetcar operators, while they are performing their duties. The law establishes different punishment levels based on the severity of the attack and whether a weapon is used, ranging from misdemeanors with fines up to $2,000 and jail time up to one year for unarmed assaults causing serious injury, to felonies with potential prison sentences up to eight years and fines up to $8,000 for attacks involving dangerous weapons. The legislation also mandates that transit vehicle owners post signs warning passengers that assaulting an operator can lead to prosecution and enhanced penalties, and it allows for increased charges if the offender has a prior conviction under this specific section.
