The California Highway Patrol has identified the man killed Friday in a solo crash on the Cuesta Grade as Ronald Lee Holstine, 44, of Paso Robles.
Holstine died after his street sweeper flipped on northbound Highway 101 just south of Tassajara Creek Road, according to the CHP.
At about 6 p.m. Friday, Holstine was driving north in heavy rain when the left side of his vehicle struck the concrete median and the vehicle flipped onto its roof and continued for a short distance.
The CHP said it was not known if Holstine was exceeding the speed limit but that it appeared he was traveling too fast for the wet road conditions and the vehicle’s tires lacked proper tread.
Holstine was not wearing a seatbelt and suffered unspecified injuries.
Officer Richard Lee of the CHP said Monday that Holstine worked for a privately owned street-sweeping company.
No other vehicles were involved in the crash, Lee said. Drugs and alcohol are not being considered a factor.
