An accident along Highway 120, just west of Crackerbox Road outside Oakdale on Tuesday, sent one driver to the hospital and closed the roadway for nearly three hours.

According to the California Highway Patrol, the Nov. 23 crash was reported just before noon north of Oakdale. Emergency personnel arrived on scene and located a Toyota pick-up truck and a Peterbilt tractor trailer combination with major collision damage.

The driver of the Toyota, a 33-year-old man from Modesto, was transported from the scene by air ambulance to Doctors Medical Center with major injuries. His name was not released as of press time.

The driver of the Peterbilt, a 52-year-old man from Turlock, was not injured.

The preliminary investigation found the driver of the 1999 Toyota pick-up was westbound on State Route 120, just west of Crackerbox Road while the 2013 Peterbilt was eastbound on 120. For unknown reasons, the CHP report indicates, the Toyota driver allowed his vehicle to partially enter the eastbound lane. The left front of the Toyota collided with the left front of the Peterbilt. The impact caused the Toyota to proceed in a northwesterly direction as it overturned. The Toyota then came to rest on its driver’s side, north of the north roadway edge. The Peterbilt came to rest north of the north roadway edge and its rear trailer came to rest blocking the westbound traffic lane.

Both eastbound and westbound lanes of Highway 120 in the area were shut down during the investigation and clean-up operations. Traffic was detoured around the scene. Crews reported the reopening of the highway just before 3 p.m. Tuesday, about three hours after the crash.

Both drivers were wearing their seatbelts at the time of the collision, the CHP said, and it was unknown if drugs or alcohol contributed to the crash. Caltrans was summoned to the scene to provide traffic control through the area.
