The collision happened on I-10 West at the Euclid Avenue offramp around 1:54 AM on January 20, 2026, when Ontario Police Department (OPD) officers located a vehicle that had crashed into a tree on the westbound side of the freeway near the offramp.

Ontario, CA – One person was killed early Tuesday morning after a single-vehicle collision on Interstate 10 in Ontario, according to the California Highway Patrol (CHP).
The collision happened on I-10 West at the Euclid Avenue offramp around 1:54 AM on January 20, 2026, when Ontario Police Department (OPD) officers located a vehicle that had crashed into a tree on the westbound side of the freeway near the offramp.
Initial CHP logs indicate that the vehicle involved had fled from officers before coming to rest after impacting a tree along the westbound I-10 Euclid Avenue offramp, prompting emergency response and a closure of the ramp.
The crash involved a single vehicle that reportedly left the roadway and struck a tree. CHP later upgraded the incident from an unknown injury collision to a fatality after emergency personnel and the coroner were summoned to the scene, indicating at least one person was killed. No information was available in early reports on additional injured parties or arrests.
Although investigation details are preliminary, early documentation suggests that the vehicle's departure from the roadway and subsequent collision with a fixed object were the primary factors of the crash. Official determination of cause remains pending further investigation.
CHP officers, Ontario Police, and coroner's personnel responded to the scene. The Euclid Avenue offramp was shut down for an extended period to allow for investigation, evidence collection, and recovery operations. Traffic controls were put in place while responders worked through the early morning hours.
The fatal collision significantly disrupted traffic on westbound I-10 at Euclid Avenue, requiring full closure of the offramp and surrounding ramps as authorities processed the scene and cleared the roadway.
The crash remains under investigation by the CHP as authorities continue to gather evidence and determine the precise events leading up to the fatal collision.
