One man suffered major injuries when a camping trailer collided with a big rig on Highway 99 in Turlock Tuesday morning.

The injured man, identified as William Thacker, 42, of Mira Loma, was rushed by ambulance to Doctors Medical Center with what the California Highway Patrol described as major injuries. He had to be freed from the vehicle by the Turlock Fire Department, who used a hydraulic tool to extricate him from the overturned truck.

The collision occurred around 9:30 a.m. Tuesday on northbound Highway 99 near W. Main Street.

A 2007 Ford F-350 pulling an Aztec two axle camping trailer and driven by Javier Zapada, 24, of Mira Loma, was in the slow lane and traveling at an estimated 60 mph. the driver moved into the middle lane and was traveling next to a big rig when Zapada began to feel the camper “fishtail back and forth,” according to the CHP report.

The right side of the truck collided with the big rig. The impact sent the big rig onto the shoulder, where it collided with the guardrail. It came to a rest partially dangling over the freeway.

The impact caused the Ford to spin before overturning and landing in the slow lane on its roof. The camper overturned on to its side.

Zapada sustained minor injuries from the crash and declined any medical treatment. Michael Thacker, who was riding in the camper suffered minor injuries and was taken by ambulance to Emanuel Medical Center.

The big rig’s driver, Jose Zavala, 31, of Livingston was not injured in the crash.

The camper had been carrying construction items and the collision sent nails, tools and other items sprawling out across the highway.

The CHP closed all three lanes of the highway before reopening one around 9:50 a.m. Traffic came to a standstill and was backed up all the way to Merced, according to the CHP. All lanes were reopened around 3:50 p.m.

It does not appear drugs or alcohol were factors in the collision.

The collision remains under investigation.
