A Centreville woman was injured in a two-vehicle crash last week in Nottawa Township.
Sheriff Mark Lillywhite said deputies were called shortly after 3:30 a.m. Wednesday to the area of M-86 and Rambadt Road.
Investigators found that a 65-year-old woman was driving west on M-86 when her vehicle crossed the centerline and struck a semi-tractor trailer heading east.
The woman suffered life-threatening injuries and was transported to Bronson Hospital in Kalamazoo. The driver of the semi had minor injuries, authorities said.
Identity of the drivers was not included in a department media release.
