Troopers say impairment may have been a factor in a crash near Tonopah overnight.
According to the Arizona Department of Public Safety, two cars were involved in the collision near milepost 90.
A Honda Passport reportedly rear-ended another car, rolled and then came to rest on the side of the road. The other vehicle veered left before coming to a stop.
Five people in the Passport, including three children, were taken to the hospital for treatment. None of them were wearing seatbelts.
The driver of the second vehicle was not hurt.
Impairment is said to be an issue in the crash, but no other information about the investigation was immediately available.
