Leaves one driver dead, the other with major injuries
By CHP – Contra Costa
DISCOVERY BAY, CA – On Thursday, August 14, 2025, at approximately 10:19 a.m., officers assigned to the California Highway Patrol’s (CHP) Contra Costa Area office responded to a two-vehicle head-on crash which occurred on State Route 4 (SR-4) westbound, just east of Discovery Bay Blvd. in the township of Discovery Bay.
Our preliminary investigation indicates a Toyota Camry, driven by an adult male, was traveling eastbound on SR-4 when, for reasons still under investigation, it crossed over the double-yellow divider lines and crashed head-on into a GMC Sierra occupied by a male adult.
Tragically, the driver of the Toyota sustained fatal injuries and was pronounced deceased at the scene. The driver of the GMC sustained suspected major injuries and was airlifted to the hospital. An impaired driving investigation was also conducted, and DUI was ruled out as a factor in this crash.
This crash remains under investigation. If anyone witnessed the incident or the events leading up to it, please contact Contra Costa Area office in Martinez at (925) 646-4980 or email your contact information to 320Investigations@chp.ca.gov to be contacted by the investigating officer.
The Mission of the California Highway Patrol is to provide the highest level of Safety, Service, and Security.
It’s getting crazy out there! I’ve seen many drivers trying to pass vehicles on the left or right to get to their destination. We need more patrols out there, we should be able to drive to grocery store and lose our life!
The Toyota driver was my brother I was on Bluetooth call with him when it happened he wasn’t trying to cross the double lines he sneezed and when he sneezed he felt pain in his chest and lost control of the car my brother always warned us to never try and cross and pass cars that it’s not worth the risk ever
