A Hilmar man riding his motorcycle Wednesday night was killed in a collision caused by a vehicle coming into his lane to pass a semi-truck.

The name of the deceased has not been released pending next of kin notification. He was 35-years-old, according to the California Highway Patrol.

The man was driving a 2005 Harley Davidson northbound on Highway 165 around 10:30 p.m. Wednesday. He was traveling at a speed of 45 to 50 miles per hour, according to the CHP.

Driving southbound on 165 in a 2013 Audi Q7 SUV was Janet Guzman, 33, of Newman and a 12-year-old boy was the passenger.

Guzman was behind a semi-truck and trailer combination. Around Oslo Road, she attempted to pass the vehicle and moved into the northbound lanes, directly in front of the motorcycle rider.

The motorcycle rider tried to avoid the head-on collision by swerving to the right, headed to the east shoulder, the CHP reported.

Guzman simultaneously swerved to her left, sending the Audi onto the east shoulder as well.

Both vehicles collided head-on on the east shoulder, causing fatal injuries for the motorcyclist, who was pronounced deceased at the scene.

Guzman and the 12-year-old boy were not injured in the crash. The driver remained at the scene.

Drugs and alcohol are not suspected as factors in the collision.

The investigation is ongoing.
