Shur was driving a 2003 Dodge east on Highway 84 near Main Street when the crash occurred at around 9:15 a.m., according to the California Highway Patrol.
For an unknown reason, he drove his vehicle across the double yellow lines directly into the path of a 2012 Toyota driving by a 48-year-old Stockton man.
The driver of the Toyota did not have time to react, and the two vehicles crashed, the CHP said.
Shur died from his injuries at the scene. The driver of the Toyota and three passengers suffered minor injuries, primarily complaints of back pain, the CHP said.
The crash closed the highway for nearly two hours.
