Ramon Diaz explains what happened when two cars collided on Interstate 5 and rolled off the highway.
Two vehicles were involved in a rollover crash on northbound Interstate 5 Wednesday evening..
Four people were seriously injured after a two vehicle crash on I-5 near the Main Street exit in National City.
A Jetta and a Toyota Highlander collided around 7 p.m. according to the CHP, San Diego police and National City police.
One witness said the two vehicles clipped each other on the freeway and both ended up rolling down an embankment onto Roosevelt Avenue.
Ramon Diaz watched as the two vehicles rolled off the road.
"I just heard the crash and when I turned around, they were spinning up on top of the freeway and they just came off," Diaz said.
He and several other witnesses tried to push the Highlander back on its wheels but it was too heavy.
Emergency crews had to pull two victims trapped in one of the vehicles.
"There was a person inside yelling at us not to move the car because I think they were hurt really bad," Diaz said.
Two patients were transported to UCSD. Another two people were transported to Mercy.
One firefighter said all those involved in the crash were wearing their seatbelts.
