(Vacaville, CA) – A 66-year-old woman from Vacaville died early Sunday when a suspected impaired driver drove against traffic on Interstate 505 and struck her vehicle head-on, according to the California Highway Patrol.
Investigators said the collision happened about 12:40 a.m. in the southbound lanes of I-505, a short distance south of Putah Creek Road. The CHP reported that dispatchers first learned of the incident through an automated iPhone crash alert, and that later phone calls indicated a multi-vehicle wreck.
According to the CHP's preliminary account, a 45-year-old man from Vallejo behind the wheel of a 2021 Chevrolet Tahoe missed his exit and turned around on the freeway. Because of a high level of suspected intoxication, officers said, he believed he was on a two-way county road and continued northbound in the southbound lanes before colliding head-on with a 2026 Nissan Kicks.
The woman driving the Nissan, who was alone in the car, did not survive and was declared dead at the scene, the CHP said. The Tahoe driver, also alone in his vehicle, had only minor injuries and was detained at the scene on suspicion of felony driving under the influence. Authorities said he would be booked into the Solano County Jail once medically cleared. Three other vehicles were damaged after running into debris left in the roadway by the initial impact. The CHP diverted southbound traffic at Putah Creek Road during the investigation and reopened the freeway around 4:20 a.m. The agency's Solano Area office asked anyone with information to come forward.
Know Your Rights After a Crash
After a serious crash, California law gives injured people and families limited time to act. Evidence like vehicle data, camera footage, and witness memories fades quickly.

Analysis of the I-505 Wrong-Way Collision
Investigations into a fatal wrong-way crash typically center on the movement of each vehicle and the condition of each driver, but any legal conclusions depend on evidence developed after the initial reports. Under California's Basic Speed Law, Vehicle Code section 22350, drivers must travel at a speed that is reasonable and prudent for the conditions; investigators often assess speed alongside the direction of travel when reconstructing a head-on collision. Vehicle Code section 21651 makes it unlawful to drive on a divided highway other than to the right of the dividing section, and a willful violation causing injury or death can be charged as a felony or misdemeanor. Because officers reported that one vehicle turned around on the freeway, section 21801, which requires a driver making a U-turn to yield to approaching traffic, may also be examined if the facts support it.
Where a driver is suspected of impairment, California law provides both criminal and civil avenues. Penal Code section 192(c) defines vehicular manslaughter, and the outcome of any criminal case is separate from a civil claim. In the civil context, Civil Code section 1714(a) states that a person is responsible for injury caused by a lack of ordinary care. Under Evidence Code section 669, a driver who violates a safety statute may be presumed negligent if the violation proximately caused the kind of harm the statute was meant to prevent and the injured party belonged to the protected class. These frameworks describe how liability could be evaluated; they do not establish what happened here.
When a crash results in death, California recognizes a wrongful death action under Code of Civil Procedure section 377.60 for a decedent's spouse, children, and certain other heirs, and a survival action under section 377.30 for claims the decedent could have brought. Damages in such cases are measured under Civil Code section 3333 by the detriment proximately caused, while section 1431.2 allocates non-economic damages according to each party's share of fault. A personal injury or wrongful death claim is generally subject to the two-year deadline in Code of Civil Procedure section 335.1.
What Families and Survivors Can Do
Families coping with a fatal crash can take practical steps while the investigation continues, including requesting the CHP collision report, preserving vehicle and scene evidence, and keeping records of medical and funeral expenses. Drivers involved in an injury or fatal crash have reporting obligations, including a written report to law enforcement within 24 hours under Vehicle Code section 20008 and a DMV report under Vehicle Code section 16000, and civil deadlines can arrive sooner than expected. Speaking with a qualified attorney early can help protect evidence and clarify options. Were you, or someone you love, involved in this crash?
