A wrong-way crash on Highway 505 in Solano County turned deadly Wednesday evening, killing the driver of a gold Toyota Prius and leaving a Subaru Forester driver hospitalized with major injuries. The collision happened around 6 p.m. near Allendale Road, about nine miles north of Vacaville, and authorities say the Subaru driver is reported to be in stable condition.
Officials' account
According to CBS Sacramento, the California Highway Patrol said the Prius was traveling the wrong way on Highway 505 when it slammed head-on into the southbound Subaru. CHP told the station that all southbound lanes were blocked at Allendale Road and that traffic was being diverted off at Putah Creek. The agency did not immediately provide a suspected cause for the wrong-way driving or a timeline for reopening the highway, CBS Sacramento reported.
Why wrong-way crashes are so dangerous
Wrong-way collisions tend to involve high-speed, head-on impacts, which makes them far more likely to cause serious injury or death than many other types of crashes. Analysis by the AAA Foundation for Traffic Safety found roughly 2,008 deaths from wrong-way crashes on divided highways between 2015 and 2018, or about 500 per year. A national survey of wrong-way driving research published on ScienceDirect reports that these collisions have higher fatality rates than other crashes and are frequently tied to impairment and fatigue.
Traffic impact and travel tips
All southbound lanes of Highway 505 remained shut down as first responders worked the scene, and officials gave no estimate for when the roadway would reopen. Per CBS Sacramento, traffic was being diverted at Putah Creek, and drivers in the area were facing significant delays.
Motorists are urged to avoid the area if possible and to check the state’s live traffic map via Caltrans QuickMap or the CHP Solano area page for updates before using I-505. The CHP is investigating the collision and has not yet released the identity of the Prius driver. Officials said they will provide more information as it becomes available.
