All lanes of northbound Highway 101 in San Jose were reopened following a fatal collision early Sunday that involved multiple vehicles, and authorities say an investigation into the accident is continuing.

According to the California Highway Patrol, an officer saw cars stopped in the lanes of northbound Highway 101 just north of the Oakland Road overpass at 1:13 a.m. Sunday, shortly after a collision had occurred.

The preliminary investigation indicates that an Acura TL with two teenage males inside jumped a curb on Oakland Road near the onramp to northbound 101, went down the embankment onto the right shoulder of the highway and came to rest in the No. 1 and No. 2 lanes, said a report issued Sunday morning by the CHP.

The disabled Acura was struck by a Toyota Camry driven by a 69-year-old San Jose man, the CHP report said. The Acura’s passenger, an 18-year-old man from San Jose, was killed by the crash.

The Acura’s driver, a 16-year-old boy from San Jose, suffered compound fractures to both ankles, and the Camry’s driver was not injured, according to the report.

Officer Henrik Bailey with the CHP said Sunday morning that after that collision, a white van crashed into one of the vehicles already on the roadway, and then swerved and hit another car.

No one was injured as a result of that collision, Bailey said, though the driver of the van was found to be under the influence of alcohol.

After the collision, the CHP had issued a Sig Alert, closing all northbound lanes south of the Oakland Road exit. All lanes reopened around 6 a.m.
