CHP said the man, driving a 2007 Volkswagon Jetta, was traveling eastbound on Altamont Pass Road when his vehicle drifted across the double yellow lines into the westbound lane.

The driver of a Volvo truck traveling in the westbound lane saw the Jetta and applied his brakes, but the Jetta hit the Volvo head-on, CHP said.

The driver of the Jetta was partially ejected from the vehicle and was pronounced dead at the scene. Officers said he was traveling at around 30 to 35 miles per hour and they do not yet know why his vehicle drifted into oncoming traffic.
