Belmont, CA – On the early morning of Friday, June 20, 2025, a single-vehicle crash resulted in the death of one person, according to CHP Fatal.
The California Highway Patrol reports that the fatal collision occurred at approximately 2:54 AM near the Ralston Avenue off-ramp from southbound U.S. 101.
Initial reports indicate that the vehicle involved was traveling alone when it left the roadway for reasons still under investigation. The driver, who has not yet been publicly identified pending notification of family members, sustained fatal injuries. No other passengers or vehicles were reported to be involved in the incident. The San Mateo County Coroner’s Office was notified and responded to the scene shortly after.
A hard closure of lanes #5 and #6 was implemented to facilitate the investigation and allow for the removal of the vehicle. Caltrans was also notified to assist with traffic control.
The cause of the crash is still being investigated. It is not yet known whether speed, impairment, or mechanical failure played a role in the accident.
CHP encourages any witnesses who may have seen the crash or events leading up to it to contact their local office to assist in the ongoing investigation.
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.
