Truck crash partially closes southbound Highway 99

A man was flown to the hospital Thursday after his truck slipped on a fuel spill and flipped over on southbound Highway 99, near Yosemite Parkway, the California Highway Patrol reported.

The man was taken to Doctors Medical Center in Modesto with moderate injuries, according to Luis Lara, CHP spokesman.

The incident was reported shortly before 10 a.m. Investigators say the spill, which is in the slow lane, appears to be hydraulic fluid or a similar substance. Lara said the driver of the mid 60s Chevrolet truck lost control after entering the slick spill. The truck struck a guardrail, and the victim was found lying on the highway's shoulder. It's unknown whether he was ejected from the truck, Lara said.

A witness at the scene, 26-year-old Jason Ward of Fresno, said his flatbed truck nearly slipped on the slick and clipped the side of the victim's truck. Fortunately, Ward was not hurt. "I'm just a little shaken up," said Ward, not long after the incident.

Lara said the spill on the highway is about 2 miles long, beginning near Martin Luther King Way. CalTrans workers are at the scene, cleaning up the spill.
