UPS big rig crashes in Pleasanton onramp to I-580

PLEASANTON, Calif. (KTVU) - A crash involving a UPS big rig, forced the closure of the onramp to eastbound Interstate 580 in Pleasanton early Wednesday morning.

The wreck happened at about 1 a.m. at the Hacienda onramp.

The truck driver told the highway patrol that he was eating a bag of pretzels, when he somehow lost consciousness, and the big rig went out of control.

The vehicle knocked down a lamp post, and ended up on its side.

Another car behind the truck ran over the light post, and suffered a flat tire.

No one was hurt in the crash, as the UPS truck driver was able to crawl out of his vehicle.

A CHP officer does not believe drugs or alcohol were factors in the crash.

The onramp was closed but later reopened.
