SAN JOSE — A female motorcyclist died in a collision with a minivan that a witness says ran a red light and traveled into the rider’s path just outside downtown San Jose on Thursday night.

The crash between a gray minivan and the motorcycle was reported just after 8 p.m. on 10th Street at the off-ramp from southbound Interstate 280.

The rider died at the scene. She was identified by the Santa Clara County Medical Examiner-Coroner’s Office as 36-year-old San Jose resident Maribel Hernandez.

Sgt. Enrique Garcia said the driver of the Nissan minivan involved in collision stopped and cooperated with traffic investigators, and that it does not appear that the driver was under the influence of drugs or alcohol.

Additional details were not immediately released by police. But a motorist who watched the collision unfold told this news organization that the minivan driver was at fault.

Adrian Ramirez, a 20-year-old San Jose resident, said his Honda Civic was stopped at a red light on the southbound I-280 off-ramp at 10th Street, in the far left lane, with the minivan two cars to his right.

Ramirez said with the stop light still red, the minivan started moving forward, giving him the impression that it was going to turn right onto 10th Street.

Instead, he said, it traveled straight ahead toward 11th Street, and as it crossed, a southbound motorcycle traveling on 10th Street collided with the left-front side of the minivan, throwing the rider off her bike and onto the hood of the vehicle.

“Right when (the minivan driver) made her way across the street, all I see is a motorcycle coming into the van on the left side,” Ramirez said.

He said the minivan driver got out and appeared panicked, and he eventually got out of his stopped car to tend to the victim, who by that point had fallen to the ground and was lodged underneath the minivan’s front tire.

“The vehicle was still in drive,” Ramirez said, referring to the minivan still being in gear.

That’s when Ramirez and about a half-dozen onlookers worked together to take the vehicle out of gear and push the minivan off the fallen rider, he said.

Ramirez said he and the other witnesses tried to tend to the injured woman, but that it was evident that she too severely injured for their help.

The collision marked the city’s 19th traffic fatality of the year. At the same point in 2016, 17 roadway deaths had been recorded.
