IRVINE – A pick-up truck hauling a trailer and another vehicle crashed on the I-5 Tuesday morning, Aug. 15, causing the truck to roll over the side of the freeway, police said.

At 5:27 a.m., a white Dodge 350 dually pulling a bobcat trailer – a flatbed commonly used to tow other vehicles – rolled over and landed in a small ravine, on the southbound I-5, just north of the Alton Parkway exit in Irvine, the California Highway Patrol said.

Workers were trying to get the truck out of the ravine; the three right lanes were blocked for awhile, said Officer Monica Posada. A SigAlert was lifted at about 9:40 a.m. and all lanes were clear.

It is unclear what happened to the Honda sedan that was also involved in the crash.

The CHP log initially said the driver of the truck was trapped inside the vehicle, but Posada said she couldn’t confirm that – because the driver hadn’t been mentioned after that initial report.

The cause of the crash is still under investigation and details about the driver’s condition were not immediately available.
