A Kalamazoo woman was hospitalized after a chain-reaction crash involving five vehicles, including two school buses on M-40 in Marcellus Township.

The collision happened around 3:15 p.m. on Friday, May 20, on M-40, south of Brody Road, according to the Cass County Sheriff’s Office.

The initial investigation shows the Kalamazoo woman was traveling south on M-40, attempting to turn east onto Brody. A Mendon man, who was also traveling south, allegedly failed to stop and struck the woman’s car. The force of the crash caused the woman’s car to go into the northbound lane of M-40, and collide with the side of a Marcellus School bus. The vehicle then hit, head-on, with a second vehicle which then was struck by a second Marcellus school bus.

The Kalamazoo woman was entrapped in her vehicle and had to be extricated by Marcellus Fire Department. She was taken to Bronson Kalamazoo with non-life threatening injuries.

No students on either school bus sustained injuries during the crash.

All drivers were wearing seatbelts on and airbags deployed in three vehicles. At this time, deputies do not believe alcohol or drugs were factors in the crash.

This crash remains under investigation.
