A 38-year-old Delton woman was seriously injured and her passenger, a 17-year-old girl, suffered minor injuries in a traffic crash Thursday.

The Kalamazoo County Sheriff’s Office reports the woman was southbound in the 10900 block of M-43 in Richland Township at about 4:30 p.m. when she lost control of her car, left the roadway and struck a tree. The unidentified woman and the teen were transported to an area hospital, where the driver is listed in serious/stable condition.

The crash remains under investigation; speed and wet road conditions appear to be factors.
