San Ramon Man Killed in Five-Vehicle Rear-End Crash on Dublin Boulevard
Dublin Police said a westbound Volkswagen Jetta stopped for a red light in a right-turn lane on Dublin Boulevard was rear-ended Monday afternoon by a Lexus ES 350 that was traveling at a high rate of speed and did not appear to brake before impact. The Alameda County Coroner's Bureau identified the man killed as Michael Bertalan, 45, of San Ramon. Two of the other people involved in the resulting five-vehicle chain reaction were left in critical condition.

What Dublin Police and Local Reporting Say Happened
According to Dublin Police and reporting from the East Bay Times, Bay City News, and Patch, a high-speed rear-end collision on westbound Dublin Boulevard turned into a five-vehicle chain reaction Monday afternoon. The initial impact happened at approximately 1:42 p.m. on May 25, 2026, just east of Regional Street, a commercial stretch anchored by H Mart and bordered by Golden Gate Drive.
Investigators said Michael Bertalan, 45, of San Ramon, was driving a Volkswagen Jetta that was stopped at a red light in a right-hand turn lane. A Lexus ES 350 sedan struck the Jetta from behind. According to the preliminary investigation, the Lexus was traveling at a high rate of speed and did not appear to brake before impact. That single strike on a stationary car set off a chain reaction that severely damaged several other vehicles and disabled all five involved in the sequence.
Alameda County firefighters used hydraulic extrication tools to free the two occupants of the Jetta. The Lexus also carried two occupants. All injured parties were taken to local hospitals, where Bertalan was pronounced dead. Dublin Police said two of the other people involved remained in critical condition. The Alameda County Coroner's Bureau identified Bertalan as the decedent.
Police initially said alcohol and drug intoxication do not appear to be contributing factors. The investigation remains active, and westbound Dublin Boulevard was closed between Golden Gate Drive and Regional Street until roughly 6:30 p.m. on Monday while the scene was processed.
Why a High-Speed No-Brake Rear-End Carries Heavy Civil Liability
California Vehicle Code section 22350, the basic speed law, prohibits driving at a speed greater than is reasonable or prudent for current traffic, weather, road, and visibility conditions, regardless of any posted limit. California Vehicle Code section 21703 requires a driver to keep enough distance behind a leading vehicle to be able to stop safely. When a moving driver hits a car that is fully stopped at a red light, neither statute leaves much room for argument on duty of care.
The civil doctrine that often follows is called negligence per se. Under California Evidence Code section 669, a violation of a public safety statute can create a presumption that the violator was negligent if the violation caused the kind of harm the statute was designed to prevent and the injured person belongs to the class the statute was meant to protect. A driver stopped at a signal who is killed by an unbraked high-speed rear-end fits squarely within both criteria.
Practically, the absence of pre-impact braking is one of the most powerful pieces of evidence a civil investigator can develop. Modern vehicles record event data through onboard modules, and that data routinely captures throttle position, brake application, vehicle speed, and steering input for the seconds leading up to a crash. Where the data confirms zero braking at speed into a stopped car, the liability dispute usually narrows to damages.
The Multi-Defendant Picture in a Five-Vehicle Chain Reaction
California follows a pure comparative fault rule, which lets a jury divide fault among any party whose conduct contributed to a plaintiff's harm. In a chain-reaction crash that begins with one driver striking a stopped vehicle at high speed, primary liability typically rests with the initial striking driver. Secondary liability can attach to any later driver in the chain who had a reasonable opportunity to avoid the next impact and did not, although that depends heavily on speed, spacing, and reaction time at the moment.
For a wrongful death case, the practical effect is that the family does not have to choose a single defendant in advance. Counsel can name the Lexus driver as the primary defendant and preserve the option to name additional drivers if the physical evidence and witness statements later suggest shared fault. The same approach applies in reverse for any of the other injured occupants in the chain: each can pursue the Lexus driver as the primary cause and assess possible cross-claims as the investigation progresses.
Multi-defendant cases also raise insurance issues that single-defendant cases do not. California requires only modest minimum liability coverage on every auto policy, and a single high-speed multi-vehicle wreck can quickly outstrip what one policy provides. Identifying every available coverage layer early often matters more in cases like this one than in routine fender-bender disputes.
Wrongful Death Damages for the Bertalan Family
California Code of Civil Procedure section 377.60 names the family members who can bring a wrongful death claim: surviving spouses, domestic partners, children, and certain other dependents who can show financial reliance on the decedent. Section 377.30 separately allows a survival action brought by the decedent's estate to recover losses the decedent personally sustained between the moment of injury and the moment of death.
Recoverable wrongful death damages in California include funeral and burial expenses, the financial support the decedent would reasonably have contributed to the household, the value of household services the decedent provided, and the loss of love, companionship, comfort, care, assistance, protection, affection, society, moral support, and training and guidance. California does not allow recovery of the family's own grief or sorrow as a separate item, but the loss-of-companionship category captures much of that ground in practice.
For a working-age decedent, the financial-support and household-services categories often anchor the economic damages model. Forensic economists and vocational experts are typically retained to project lost lifetime earnings, benefits, and the dollar value of services the decedent would have provided. Many families in this position consult a wrongful death lawyer or a car accident lawyer to understand what each category is worth in a real California courtroom rather than in a generic settlement calculator.
Separate Personal Injury Claims for the Critical-Injury Victims
Two of the people involved in the chain were reported in critical condition. Each of those injured people has an independent personal injury claim that does not depend on the wrongful death action. California recognizes recovery for past and future medical expenses, lost wages and lost earning capacity, future medical and life-care needs, out-of-pocket expenses, and pain and suffering.
Critical-condition trauma cases usually involve overlapping liens from health insurers, hospital systems, Medi-Cal or Medicare, and short-term and long-term disability carriers. Those liens can swallow a large slice of a settlement if not negotiated. A personal injury lawyer handling this kind of case typically coordinates the lien picture in parallel with the liability investigation, rather than leaving it until the end.
Where multiple injured claimants share a single per-accident policy limit on the at-fault driver, an early evaluation of policy limits matters. If the Lexus driver carried only the minimum required coverage, the policy may be exhausted long before the medical bills from a single critical-condition patient are paid. That is where underinsured motorist (UIM) coverage on the injured parties' own auto policies often becomes the difference between a real recovery and an empty judgment.
Evidence Preservation in the First Days After a Multi-Vehicle Crash
The Regional Street and Golden Gate Drive corridor is dense with commercial buildings, big-box retail, and restaurant parking lots, which means the area carries a high concentration of business surveillance video. That footage typically overwrites on a rolling seven to thirty day cycle, and once it is gone, it is gone. Dashcam recordings from other drivers caught in the closure window can also be lost when phones and cameras are reused.
On the vehicle side, the Lexus ES 350 contains an event data recorder that may have captured the seconds before impact. The Volkswagen Jetta and several of the other vehicles also carry modules that can be downloaded with the right tools. Preservation letters from civil counsel can keep the vehicles, the modules, and the supporting paperwork in place while the investigation continues, rather than allowing the cars to be totaled out, salvaged, and crushed on the insurance carrier's schedule.
The Alameda County Coroner's Bureau report, the Dublin Police traffic collision report, and any toxicology results on the Lexus driver will fill in the rest of the official record. Families and other injured parties usually request those records early, both to confirm the chain of events and to identify additional witnesses and responders who may have observed details that did not make it into the initial press releases.
