One motorist was killed, two others suffered major injuries, and an additional six people sustained minor injuries when a six-vehicle collision involving a semi-truck occurred on Monday at 5:15 p.m on the 120 bypass. A semi-truck owned by J.B. Carrier, of Reno, Nevada, jackknifed when it was breaking for the traffic from a collision.  One truck, that overturned on its top, was smashed by the impact semi as were other cars.  

The first responder, Manteca Fire Department Battalion Chief David Marques, arrived on scene to find some 20 commuters out of their vehicles trying to assist. Marques administered first aid to the injured, keeping heads and necks supported. Bystanders used fire extinguishers on smoking vehicles to keep them from bursting into flames.

The motorist that was fatally was pinned in his car and had to be removed by firefighters. The eastbound 120 Bypass was closed down by the California Highway Patrol 15 firefighters attended to the crash victims. Multiple ambulances rushed to the scene to transport the injured to local hospitals. Most of the vehicles were removed from the scene on flatbed tow trucks as the condition of the vehicles prevented them from being towed or driven away.

When the 120 bypass first opened over three decades ago, approximately 20 motorists lost their lives in the first year. The death rate was reduced after it was converted into a freeway. There are still a significant number of accidents that occur in the area. In the past year, first responders say an average of two accidents a week happen on the 120 corridor, in close proximity to where this accident occurred.
