PACIFICA (CBS SF) -- A man was rescued Friday after his rental van plunged more than 100 feet off a cliff and crashed into the Pacific Ocean on Highway 1 outside the Devil Slide's tunnel, authorities said.
Cal Fire Battalion Chief David Cosgrave said the driver "swerved and then careened over the edge and into the ocean."
The California Highway Patrol reported the accident on Highway 1 between Montara State Beach and Gray Whale Cove at 7:52 a.m. On helicopter video, a man was seen being aided on the rocks by rescue team members who had repelled down the cliff.

Cosgrove said the only occupant of the van had already gotten out of the vehicle and scurried up the rocks.
The man was pulled up the cliff and appeared not to be seriously injured. He was loaded onto a stretcher and taken by ambulance to San Francisco General Hospital. His condition was not immediately known.
"He claimed to not have any serious injuries," Cosgrove told reporters. "We were able to bring him up on a rope system and he was treated for paramedics for hypothermia."
