Emergency personnel responded at 6:31 p.m. when witnesses reported a Dodge Durango had crashed into a parked vehicle.
Witnesses said the man was not conscious when they ran out to the vehicles, but he did come to before police arrived.
Grand Haven Department of Public Safety Officer Chris Armstrong said the man had a possible medical episode. His car went toward the side of the road and crashed into an older model Ford Bronco, pushing it several feet down the street.
There was nobody inside the parked vehicle.
The man’s name was not available at the scene.
