ONTARIO, San Bernardino County, Calif., Nov. 3, 2026 — A vehicle rolled onto its roof on westbound Interstate 10 near Etiwanda Avenue early Monday morning, November 2, according to the California Highway Patrol.
The crash was reported shortly before 12:30 a.m. near the Etiwanda Avenue off-ramp. Radio traffic logged by the CHP indicated a vehicle crossed from the eastbound side of the freeway to the westbound side before the rollover happened. A gray vehicle was also reported to have spun out and struck traffic control barrels in the center divider, and the CHP log reflects that multiple vehicles were involved in the incident, with unspecified lanes blocked.
The CHP's initial classification listed the collision as having unknown injuries before it was updated in the log to reflect units already en route, and the agency's dispatch notes do not state whether anyone was transported for treatment. A tow truck was requested for the overturned vehicle, and a California Department of Transportation crew was asked to respond with a street sweeper to clear sand from two lanes on the westbound side near the Etiwanda off-ramp. A nearby freeway sign was also reported knocked down during the response.
Ontario police were separately notified of the multi-vehicle collision and the blocked lanes.
The cause of the crash remains under review. We are hoping for the best for everyone involved and their families.

Frequently Asked Questions
Which vehicles are most prone to rollovers?
Taller, narrower vehicles such as SUVs, pickup trucks and vans have a higher center of gravity and are statistically more likely to roll over than lower-profile passenger cars, especially during sharp steering maneuvers.
How does seat belt use affect rollover survival?
Seat belts keep occupants positioned inside the vehicle during a rollover. Unbelted occupants are far more likely to be thrown against the roof or ejected, which greatly raises the risk of serious injury or death.
What is a "tripped" rollover?
A tripped rollover happens when a vehicle's tires hit a curb, soft shoulder, guardrail or other obstacle that causes it to tip over, as opposed to an "untripped" rollover caused by sharp steering or a sudden maneuver at speed.
How can drivers reduce rollover risk?
Keeping tires properly inflated, avoiding sudden swerves, and slowing down on curves or when changing lanes can help a vehicle stay stable and keep its wheels on the road.
