Authorities in northern New Jersey are trying to determine what caused a single-car crash that left three men seriously injured.

West Milford police say the men, all believed to be 19-year-old Middlesex County residents, were hurt when the car crashed into a drainage ditch around 5:30 a.m. Friday.

They were flown to hospitals, but details on their injuries were not disclosed.

Investigators remained at the scene for several hours on Friday, but the cause of the crash was not immediately known.
