A Turlock man was killed Friday morning when his pickup truck plunged down a steep ravine and into an irrigation canal, the California Highway Patrol reported.

The name of the deceased has not been released, pending next of kin notification. The CHP said he was 31 years old and from Turlock. He was driving a 1993 Chevrolet pickup truck.

The solo vehicle crash happened on Harding Avenue, west of Moffett Road on the outskirts of Turlock.

Harding is a tattered, one-lane road running parallel to an irrigation canal.

There were no witnesses to the crash, but based on the evidence at the scene, the CHP investigators believe the driver was headed eastbound on Harding Road, when for an unknown reason he let the pickup truck drift off the road and onto the south grass shoulder, where the right side of the pickup struck a metal pole.

The impact caused the pickup to veer to the north and down the ravine, where it overturned into the irrigation canal, landing on its roof. The canal had a shallow amount of water in it, said CHP spokesman Officer Tom Olsen.

The 31-year-old was not wearing a seat belt, according to the CHP and was ejected out of the pickup.

It’s unknown what time the crash happened. It was discovered Friday morning by a passerby, Olsen said. The 31-year-old was pronounced deceased at the scene.

It’s unknown at this time if drugs and/or alcohol contributed to the collision.
