A woman who was struck and killed after pulling over and exiting her car on Interstate Highway 680 in Walnut Creek late Sunday night has been identified.
Diana Quezada-Martinez, 24, of Pittsburg, was driving onto southbound Highway 680 from the Rudgear Road on-ramp when she apparently experienced car problems and pulled over to the shoulder, according to the California Highway Patrol and Contra Costa County coroner’s office.
A short time later, Quezada-Martinez exited her car and was hit by a Mercedes-Benz sedan heading onto the on-ramp, CHP Officer John Fransen said. She died from her injuries a short time later.
The driver of the Mercedes stopped at the scene and cooperated with the CHP investigation.
Neither the victim nor the Mercedes driver appears to have been under the influence of drugs or alcohol at the time of the crash, Fransen said.
Fransen said the case is the latest of several fatal freeway collisions in Contra Costa County in recent weeks:
“The freeway is a very dangerous place, even on-ramps and off-ramps. … We ask people to exercise extreme caution around freeways and if a vehicle becomes disabled, it’s usually best to stay in the vehicle and call 911 so we can get out there.”
Anyone with additional information about the collision is asked to call the CHP’s Contra Costa area office at (925) 646-4980.
