One man died and another man was injured when a box truck overturned along northbound Highway 101 just north of McKee Road in San Jose early Wednesday morning, according to the California Highway Patrol.
The solo-vehicle wreck, which occurred around 3:45 a.m., blocked multiple northbound lanes for several hours during the morning commute, snarling traffic along the major South Bay artery, according to Sgt. Daniel Hill with the CHP.
The driver of the truck, who has been identified as a 67-year-old man out of Orange County, told authorities that he may have fallen asleep before he veered off the roadway, struck a concrete container or box on the side of the highway, and overturned, according to Hill.
A 64-year-old passenger reportedly sleeping in the truck at the time of the crash died at the scene, according to Hill. The driver suffered major but non-life-threatening injuries.
Hill said authorities do not believe that alcohol, drugs or reckless driving played a role in the wreck.
"Quite simply just driver fatigue at this point," Hill said.
All northbound lanes of the highway were blocked after the crash occurred, but the far left lane was later reopened. All but one lane reopened around 9:45 a.m., according to the CHP.
No further information was immediately available.
