An on-duty Stanislaus County Sheriff’s deputy sustained serious injuries when a truck crashed into him while he was riding his motorcycle in Turlock.

The deputy, Caleb Collins, was transported by ambulance to Doctors Medical Center with major injuries, according to the California Highway Patrol.

The driver of the truck, Davis Buhrmann, 33, of Turlock was arrested on suspicion of driving under the influence.

The collision happened at 6:49 a.m. Thursday at the intersection of W. Main Street and N. Tully Road.

Collins was driving a 2020 BMW motorcycle westbound on W. Main Street in the number 1 lane. 

Buhrmann was driving a 2001 Ford pickup eastbound on W. Main Street in the far left turn lane.

Collins had a green light and was traveling through the intersection when Buhrmann made a left turn, colliding with the motorcycle.

The impact ejected Collins off the motorcycle and he landed on the road.

Buhrmann was contacted at the scene by the CHP and showed signs of being under the influence, said CHP spokesman Officer Thomas Olsen. After a field sobriety test, Buhrmann was arrested on felony charges of driving under the influence and DUI causing injury.
