A driver was flown and passenger also was hospitalized after a crash in Crystal Lake early Sunday evening.

The Crystal Lake Police and Fire Rescue Department was called to Route 14 near Lucas Road about 5 p.m. Sunday, police said.

The driver of a Chevrolet SUV suffered non-life-threatening injuries and was flown to a local hospital, while a passenger also had non-life-threatening injuries but was taken to a local hospital, police said.

Police said a preliminary investigation found a Ford SUV was unattended in the Route 14 southeast-bound lanes, just north of Lucas Road. The Chevrolet was headed in the same direction and “subsequently struck the rear of the unoccupied Ford,” police said.
