Santa Clara County, CA – On the afternoon of Monday, April 20, 2026, a single-vehicle collision resulted in a fatality on westbound State Route 152 near Dinosaur Point Road, according to CHP Fatal.
The California Highway Patrol reports that the accident took place around 4:34 PM.
Authorities said a vehicle rolled over multiple times before coming to rest on its roof, with the driver remaining inside and a female occupant ejected onto the slow lane. A bystander was performing CPR on the ejected occupant at the time of initial reports.
Santa Clara County Fire Department and CAL FIRE responded to the scene, with CAL Star 5 air medical unit also dispatched. A fire department truck was positioned diagonally to block the slow lane while emergency personnel attended to those involved.
A traffic break was initiated from the Dinosaur Point area while the number two lane was blocked during the response. The Santa Clara County Sheriff’s Office was notified and responded. A tow was requested for the vehicle, which sustained rollover damage and remained on its roof.
A westbound traffic break was later initiated at Upper Cottonwood to facilitate the investigation. All lanes were closed at approximately 8:37 PM before being fully reopened at approximately 8:51 PM.
The incident was confirmed as a single-vehicle fatality. No additional details regarding the identity of the deceased had been released at the time of reporting. The investigation remains ongoing.
Single-Vehicle Collisions
In some cases, investigations may reveal that even in a single-vehicle accident, nearby drivers or unsafe road features share some responsibility. California’s comparative negligence rule means that, even if those injured in accidents are found partially at fault, they may still be eligible to receive partial compensation for damages through a wrongful death claim.
