Two people and their dog had to be rescued from a car that accidentally crashed through a guardrail at the marina in Long Beach, California, leaving the passengers trapped in a sinking vehicle.

Jeff Jones, who owns a boat-towing service at the marina, recorded the rescue as lifeguards and firefighters jumped into the water to save the passengers  a mother, and son.

“I heard a noise and turned around, and I saw a car drive right past me through a guardrail and into the water,” Jones said. “I’m usually the person who would jump in to help but I had major surgery 10 days ago. So I ran to the long beach fire and lifeguard station, which was literally right there.”

“They just came barreling right through. I turned around, and you know, it was just one of those things,” Jones said. “It was very hectic, the fire trucks came, the local Marine patrol came. It just got pretty chaotic, very fast.”

According to the Long Beach Fire Department, "LBFD Lifeguard units responded to reports of a submerged vehicle just after 1 PM [Saturday]. Lifeguard and vessel assist personnel arrived and made water entry and extricated an elderly couple from the vehicle. The couple was treated on scene and released. Accident under investigation."

Although the video didn’t capture the entire incident, Jones said that the rescuers were able to pull the two people and the dog through the doors without having to break the windows.

“Everything went really smoothly. I spoke to one of the passengers afterward, and he said it felt like everything happened in slow motion. It felt like it was not a big deal,” said Jones.

Long Beach police, who were called to the 200 block of Marina Drive around 1 p.m. Saturday following a report of the car going into the water, didn’t suspect that the driver was under the influence, but that he had just made a mistake.

“No sooner did I hop in the water, the lifeguard captain was handing over the older lady to me,” said Jeff Perez. “I would just hope people would do the right thing, and that’s what we’re all here for, to be here for one another and for support.”

Dr. Gordon Giesbrecht, a professor at Canada's University of Manitoba and a world leader in research into submerged vehicle escape, has three simple rules for getting out of a sinking car. "Seatbelts, windows, out — children first. That means, get your seatbelts off, then get the windows open," he said. Even if the car's windows are electric, they should still work for at least 10 to 60 seconds. Once you've opened the windows, help children or others who may need assistance, out of the car. "Especially with children, push them out of the window ahead of you, then follow them," he said.
