A motorist fled the scene after causing a wreck involving two semi trucks that shut down the 210 Freeway in Los Angeles early on Thursday morning.

The accident happened on April 26th at approximately 1:20 a.m. in Los Angeles, California.

According to the LA Times, a motorist was traveling along the 210 Freeway westbound when they crashed into the back of a semi truck. The force of the impact damaged the rear of the trailer and completely crumpled the front of the sedan and the motorist fled the scene, leaving the seriously damaged vehicle blocking lanes of traffic.

A second semi truck hauling double trailers then crashed into the disabled sedan, flipping the rig and sending the back trailer over the concrete barrier wall and onto the tracks of the Metro Gold Line light rail, while the wrecked cab and front trailer remained on the 210.

The driver of the second semi truck was transported to a nearby hospital with minor injuries, but the condition of the first driver is not known. Neither trucker has been publicly identified and the motorist who fled the scene has not been located, California Highway Patrol reports.

The westbound lanes of the 210, as well as the Metro light rail, have been shut down to allow for crews to clear the wreckage and investigate the incident. There is no estimated time of reopening for the freeway, but officials say cleanup could last into the evening. Drivers are urged to take an alternate route.
