A helmet may have been the only thing that saved the life of a motorcyclist on Route 422, police said.

The man's motorcycle and a small SUV collided late Friday morning on the ramp from Route 422 East to Route 724 East in North Coventry Twp., Chester Co.

The SUV appeared to be stopped at a stop sign because of construction in the area, police said.

A stretch of Route 422 was closed in both directions so that the motorcyclist could be flown to a hospital.
