(CNN) — Two adults and two children narrowly escaped serious injury when their Tesla fell off a cliff along California’s Pacific Coast Highway and crashed onto a rocky beach some 250 feet below.
The incident happened this morning in an area called Devil’s Slide, located about 20 miles south of San Francisco.
“We were very shocked” to learn that the occupants of the car had survived the crash, Brian Potanger said, Battalion Chief of the California Coastal Fire Protection District.
Authorities said the white, four-door Tesla sedan was traveling south on Highway 1 just south of the Tom Lantos Tunnel between Pacific and Montara when it skidded off the road. He did not specify the cause of the accident.
A spokesman for the California Highway Patrol told CNN that he did not believe any of Tesla’s self-driving features were active at the time.
“The damage to the vehicle indicates that it collided and then overturned multiple times,” Potenger said. The car stopped on its wheels, he said.
Firefighters hauled the car down the cliff while other rescuers watched through binoculars.
“While we were doing this, we could see movement in the front seat through the windshield,” Potenger said. “So we knew we had at least one person alive.”
The occupants of the car were trapped inside the crashed vehicle, officials said. The teams freed the two boys and used ropes to lift them off the cliff in baskets.
A short time later, a California Highway Patrol helicopter took the two adults to safety. The patrol released a dramatic video of a helicopter lowering a rescue team by cables to the crash site as waves crashed against the rocks below.
San Mateo Sheriff’s Office said this monday that two adults suffered “non-life-threatening injuries” and that two children were “uninjured”.
The occupants of the car were taken to a nearby hospital for treatment. There was no update on his condition as of Tuesday.
Authorities have not released the identities of the occupants of the car or said whether they are related.
