Crimes: assaultive; harassing, interfering with, or injuring a letter carrier; prohibit, and provide penalties. Amends sec. 81d of 1931 PA 328 (MCL 750.81d).

HB 5483 amends Michigan's penal code to specifically protect United States Postal Service letter carriers by adding them to the list of protected individuals under assault laws. The bill increases penalties for assaulting, obstructing, or endangering these workers based on injury severity: up to 2 years for basic assault, 4 years for serious injury requiring medical care, 15 years for serious bodily impairment, and 20 years if the assault causes death. It clarifies that existing penalties for assaulting law enforcement or emergency personnel also apply to letter carriers when they are performing their duties. The law takes effect 90 days after enactment and does not affect other potential charges for the same incident.
