A fatal collision involving two semi-trucks shut down the westbound Interstate 10 at the Interstate 15 interchange in Ontario on Tuesday afternoon, October 21, 2025.
According to the California Highway Patrol, the crash occurred around 1:14 p.m. near the transition ramps.
Multiple vehicles were involved, including two big rigs, one of which caught fire after the impact. Witnesses reported that one of the trucks was braking but failed to stop in time, colliding with another semi. A third vehicle may have been struck between them, though that remains under investigation.
Flames were seen coming from the gas tank of one of the trucks before firefighters quickly extinguished the blaze. Four lanes were initially blocked as emergency crews responded. One person was transported to Pomona Valley Medical Center with major injuries, and at least one fatality was confirmed at the scene.
The cause of the crash remains under investigation, and the identity of the deceased has not been released.
Don’t Know What To Do After An Accident?
Your safety and rights depend on what you do next after an accident. Remember the following steps if you find yourself in one:
- Check yourself for any injuries.
- Stay on the scene, call 9-1-1, and wait for emergency responders.
- Move your vehicle to the road shoulder if safe; turn on hazard lights.
- Fully cooperate with law enforcement and stay until cleared to leave.
- Document the scene and injuries with photos and videos.
- Seek immediate medical attention.
- Contact your insurance company and find a personal injury lawyer for legal advice.
What A Lawyer Can Do For You
Many victims put off calling a lawyer even if they sustain injuries after an accident. However, lawyers can help you in many ways. They can provide you with police reports, CCTV footage, and witness statements to strengthen your case. Your attorney will also negotiate with insurance companies to get you fair compensation. The best part is that they will do all of these things for you at no upfront cost. So if you’re injured in an accident, hire a personal injury attorney to recover medical bills, car repair costs, lost wages, and pain and suffering.
