Winters, CA – A 66-year-old Vacaville woman was killed in a wrong-way crash on Interstate 505 early Sunday morning, and a Vallejo man was arrested on suspicion of felony DUI, according to the California Highway Patrol.

The fatal collision occurred at approximately 12:40 a.m. Sunday, August 30, 2026, on southbound I-505 just south of Putah Creek Road.
According to CHP, a 45-year-old Hispanic man from Vallejo was driving a 2021 Chevrolet Tahoe when he missed an exit and made a U-turn on the freeway. Investigators said the driver was highly intoxicated and mistakenly believed he was traveling on a two-way county road. He then traveled northbound in the southbound lanes of I-505 and collided head-on with the Nissan Kicks.
The Nissan driver was pronounced dead at the scene. The Tahoe driver, who was also a sole occupant, suffered minor injuries and was arrested on suspicion of felony DUI. After medical clearance, he is expected to be booked into the Solano County Jail.
Three additional vehicles were damaged after striking debris from the initial collision.
CHP Solano Area officers responded after an automated iPhone crash alert was received and investigated the collision. Authorities also worked to clear the roadway and manage traffic during the investigation.
Southbound I-505 traffic was diverted at Putah Creek Road while the crash investigation and cleanup were underway. The freeway was fully reopened at approximately 4:20 a.m.
The crash remains under investigation. CHP is asking anyone with additional information about the collision to contact the Solano Area office.
