UPDATE 2:20 p.m.: The man who suffered major injuries in a crash this morning on Highway 58 was flown by CHP helicopter to a local hospital and later arrested on suspicion of driving under the influence.
CHP officials released a few other details this afternoon about the collision, which happened about 9:30 a.m. on Highway 58 about 32 miles east of Highway 101.
At that time, the man was driving west on the highway in a Toyota Prius, while a trailer hauling dirt was headed in the opposite direction.
For some reason, during a curve in the road, the driver of the Prius entered the eastbound lane and collided with the trailer, causing it to overturn, CHP Officer Bill Long said.
The driver was trapped, extricated and flown to Sierra Vista Regional Medical Center for treatment. He was also arrested on suspicion of DUI, Long said. Authorities have not yet released his name.
The man did have a female passenger in the Prius. She complained of pain and was taken by ground ambulance to a local hospital.
The driver of the trailer was not injured.
Cleanup efforts are still under way, but the highway is open and traffic is flowing smoothly, Long said.
