Vacaville, CA (October 31, 2026) – Gregory “Greg” Tobias, 29, was killed in a four-vehicle crash on eastbound Interstate 80 just west of Lagoon Valley Road, according to the California Highway Patrol. It happened at about 2:35 a.m. on October 31. The Solano County Coroner identified him.
A preliminary investigation indicates Tobias was driving a blue Hyundai Tucson east on I-80 when it overturned, the CHP said. The cause remains unknown, and the SUV came to rest across the eastbound lanes. Three vehicles then struck the disabled SUV. The drivers were a 20-year-old man in a blue BMW coupe and a 40-year-old man in a gray Buick SUV. A 60-year-old woman was driving a white Kia sedan.
Tobias’s wife, also 29, was a passenger in the Hyundai and was taken to Kaiser Permanente Vacaville Medical Center in critical condition. Family members told news outlets she was declared brain dead on November 6. The 60-year-old Kia driver suffered major injuries, and the CHP did not report injuries to the BMW or Buick drivers.
Investigators believe the couple was wearing seat belts. Alcohol and drugs are not currently suspected, though investigators will examine them, the CHP said. No arrests have been made.
The CHP has not said why the Hyundai overturned or how fast the other three vehicles were traveling. Nor has it said whether a vehicle or roadway problem played a role. Anyone who saw the crash is asked to contact the CHP Solano Area office.
This is a developing story. Details may change as the investigation continues.
Liability When Drivers Strike a Disabled Vehicle on a California Freeway
The California Office of Traffic Safety counted 318 fatal and injury collisions in Solano County between 9:00 p.m. and 2:59 a.m. in 2023. That ranked the county 11 of 58. Claims after a crash like this usually turn on two questions: why the SUV overturned, and what the three drivers behind it could have done.
The CHP has not said why the Hyundai rolled, how fast the others were going, or whether a vehicle or roadway problem played a role. After a death, close family members can bring a wrongful death claim. California’s pure comparative fault rule lets a family recover even when fault is split.
For the families and the injured driver, three points matter most while the investigation continues:
- First steps: Request the CHP crash report, ask that the vehicles not be released or salvaged, and keep every funeral and medical bill.
- Who may be liable: Any driver whose speed or attention contributed, plus whoever or whatever caused the rollover. A defective part, a poor repair, or a road condition could bring a manufacturer, repair shop, or public agency into the claim.
- Deadlines: Claims must generally be filed within two years of the crash or death (CCP 335.1), so work from October 31, 2028. If a public road condition played a part, a claim against the responsible agency is due within six months, by April 30, 2027 (Govt. Code 911.2).
