SAN JOSE -- A driver headed the wrong way on San Tomas Expressway died Saturday after plowing into an oncoming car, police said.

A 59-year-old San Jose man, whose name was not released, somehow ended up driving north on the southbound side of San Tomas Expressway around 9 p.m., said the California Highway Patrol. His 1990 Honda slammed head on into a 2010 Toyota, which was driving about 45 miles per hour in the southbound lanes, just north of Williams Road.

The victim was pronounced dead at the scene. Police, however, did not release details about injuries to the other driver, Yong Ling Shiao, 68, of Campbell. Both drivers were wearing seatbelts, police said.

The cause of the accident remains under investigation.
