Car Accident Lawyer Ontario

Written and reviewed by David Gammill

Ontario sits at one of Southern California’s most consequential road junctions — a city of nearly 185,000 where Interstate 10, Interstate 15, and State Route 60 converge within a few miles of each other, and where Ontario International Airport and a dense concentration of Amazon, UPS, FedEx, and regional logistics facilities generate commercial vehicle traffic that dwarfs what the city’s road network was originally designed to carry.

The accident record reflects this pressure. CHP incident logs document multi-vehicle crashes on I-10 East near Mountain Avenue, vehicles flying off the freeway onto surface streets near South Ritner Avenue, three-vehicle crashes on SR-60 West at Milliken Avenue, and collisions on I-15 near the TL-10 East on-ramp. These aren’t anomalies. They are Ontario’s daily accident environment.

If you or a loved one were injured in an Ontario car accident, Gammill Law is ready to fight for every dollar California law allows.

Ontario’s Three-Freeway Environment: Where Serious Accidents Happen

Interstate 10 — The San Bernardino Freeway

I-10 through Ontario is part of a San Bernardino County freeway corridor that traffic safety research has identified as accumulating one of the highest total crash and fatality counts in California — a studied segment documenting 36 crashes and 39 fatalities over a 44-mile stretch. Through Ontario, I-10 carries commercial freight bound for the logistics facilities that have transformed the Inland Empire into one of the country’s busiest distribution markets, alongside regional commuter traffic. When commercial trucks and passenger vehicles collide on this corridor, the injuries are severe.

Interstate 15

I-15 passes through Ontario’s eastern edge, carrying the combined traffic of San Diego-bound freight and Las Vegas-bound leisure travelers. The I-15/I-10 interchange near Ontario is one of the most heavily trafficked freeway junctions in the region. CHP records document consistent accident activity at this convergence point — where drivers making rapid routing decisions at highway speeds produce the merge conflicts, sudden braking events, and sideswipe crashes characteristic of high-volume multi-freeway interchanges.

State Route 60 — The Pomona Freeway

SR-60 through Ontario’s southern corridor carries both regional commuter loads and a significant commercial trucking presence between the Inland Empire and the LA basin. The Milliken Avenue interchange on SR-60 appears specifically in Ontario’s recent CHP records as a documented crash concentration point.

Surface Streets: Milliken Avenue, Euclid Avenue, Haven Avenue

Ontario’s primary north-south surface arterials generate consistent intersection accident activity. Milliken Avenue near SR-60 is specifically documented in CHP records. Euclid Avenue and Haven Avenue carry comparable north-south commercial and commuter loads. The area around Ontario Mills Mall sees periodic volume surges during peak retail periods — increasing accident risk on Haven Avenue, Fourth Street, and Milliken Avenue approaches to the center.

Ontario’s Logistics Boom: Why Commercial Vehicle Claims Are Different Here

In the past decade, Ontario and the western Inland Empire have become one of the largest logistics hubs in the United States. The result is commercial vehicle traffic on Ontario’s roads at volumes that fundamentally change the accident landscape for anyone injured here.

When a logistics company vehicle causes your accident in Ontario, the claim is not just between you and the driver:

• The driver may be an employee or an independent contractor — and the distinction affects which entity bears vicarious liability
• The carrier is subject to FMCSA safety regulations governing hours of service, vehicle inspection, and driver qualification
• The warehouse client may have contracted with the carrier in ways that create additional liability exposure
• Electronic logging devices capture speed, braking, and driver behavior data in the seconds before the crash — data that must be preserved immediately

Ontario’s explosion of Amazon, UPS, FedEx, and third-party logistics facilities has produced a specific class of injury claim that requires investigation far beyond the accident report. Our commercial truck accident attorneys handle these cases in Ontario and throughout the Inland Empire.

Ontario International Airport: Rideshare and Commercial Vehicle Accidents

Ontario International Airport has grown substantially and now handles millions of passengers annually alongside a major cargo operation. The ground access roads — primarily Haven Avenue, Airport Drive, and the I-10 and I-15 approach corridors — generate specific accident conditions:

Rideshare accidents near ONT Airport follow California’s three-tier coverage analysis:

• App off → driver’s personal auto policy
• App on, waiting for a match → limited rideshare company contingency policy
• Active ride accepted, passenger in vehicle → rideshare company’s full commercial policy (up to $1 million)

We subpoena platform records, confirm the driver’s app status at the moment of impact, and ensure you recover from the correct — and highest available — coverage tier.

Frequently Asked Questions: Car Accident Lawyer Ontario

Q: A logistics truck from a warehouse I’ve never heard of hit me on I-10. How do you find who’s liable? 

A: FMCSA carrier database searches, USDOT registration records, and the cargo’s bill of lading identify the operating carrier. We then investigate the full contracting chain — driver employment status, carrier-warehouse client relationship, and vehicle insurance coverage. Identifying every liable party at the outset is critical to maximizing your recovery.

Q: My accident happened at the I-15/I-10 interchange. Several cars were involved. How does fault work? 

A: California’s comparative fault system distributes liability proportionally across all responsible drivers. In multi-vehicle interchange accidents, we investigate the full sequence — which driver initiated the chain of conflicts, which had adequate stopping distance, and which specific traffic violation was the proximate cause of your injuries. Accident reconstruction experts are engaged when the sequence is disputed.

Q: I was hurt in a rideshare crash near Ontario Airport. The driver had a passenger. Which insurance applies? 

A: When a rideshare driver has accepted a ride request and has a passenger in the vehicle, the company’s full commercial liability policy applies — potentially up to $1 million. We confirm the driver’s exact app status through subpoenaed platform records and ensure you recover the maximum available compensation.
