A motorcycle crash in Fort Gratiot Township Sunday afternoon seriously injured a motorcyclist. According to St. Clair County Sheriff Tim Donnellon, a 46 year old Fort Gratiot man was riding his Harley Davidson southbound on Lakeshore road shortly before 5:00 p.m. A 20 year old man from Yale was driving his 2009 Ford Fusion northbound and turned left in front of the motorcycle in the 4500 block of Lakeshore. The motorcycle crashed into the car head-on, ejecting the man from the bike. The motorcyclist was transported by Tri-Hospital EMS to McLaren Port Huron Hospital and later transferred to Henry Ford Hospital in Detroit. Neither the driver of the car nor his passenger, a 20 year old man from Columbus Township was injured. The Sheriff’s Office Accident Investigation Unit was called to the scene of the crash, which remains under investigation. It is believed drug use by the driver of the car was a contributing factor in the incident.
