Car Accidents in Pomona: Freeway Junctions, Arterials and Claims

Pomona sits at the eastern edge of Los Angeles County where four freeways—I-10, SR-57, SR-60 and SR-71—come together within a few miles. The SR-57/SR-60 interchange at the city’s southwest corner, sometimes called the Diamond Bar junction, and the I-10/SR-57 and SR-60/SR-71 junctions carry Inland Empire commuters and heavy truck traffic bound for the warehouses of the Chino Valley.

The city itself is older and denser than its neighbors, with a historic downtown, Cal Poly Pomona and Western University of Health Sciences, and the Fairplex, home of the LA County Fair and year-round events. Holt Avenue, Garey Avenue, Mission Boulevard, Indian Hill Boulevard and Towne Avenue are the main arterials.

Who writes the collision report in Pomona

The Pomona Police Department handles collisions on city streets. The California Highway Patrol handles I-10, SR-57, SR-60 and SR-71. Collisions on the Cal Poly Pomona campus are handled by University Police; collisions on Fairplex grounds during events are usually documented by Fairplex security and Pomona PD.

Where Pomona collisions happen

SR-57 / SR-60 interchange

A long weaving section where the two freeways share lanes; truck traffic and lane changes across several lanes make this one of the region’s most frequently cited crash locations. Rear-end and sideswipe collisions, often with several vehicles, are commonly reported.

I-10 through Pomona

The San Bernardino Freeway carries heavy truck volumes; the Garey, Towne and Indian Hill ramps see congestion-related rear-end collisions.

Holt Avenue and Mission Boulevard

Long commercial corridors with auto businesses, motels and pedestrian activity; nighttime pedestrian collisions and left-turn crashes are recurring.

Garey Avenue and Towne Avenue

North-south arterials through downtown and past Pomona Valley Hospital Medical Center with school and hospital traffic.

Common collision scenarios

• Multi-vehicle collisions in the 57/60 weaving section.
• Truck-involved collisions on the 10, 60 and 71.
• Pedestrian collisions on Holt and Mission.
• Left-turn collisions on Garey and Indian Hill.
• Event traffic collisions around the Fairplex.

Courts, hospitals and local practicalities

The Pomona Courthouse South of the Los Angeles Superior Court handles civil and other matters for the east San Gabriel Valley. Pomona Valley Hospital Medical Center is a Level II trauma center serving the Pomona Valley and nearby Inland Empire communities.

Because Pomona borders San Bernardino County (Montclair, Chino), collisions near the county line may be handled by different agencies and courts depending on which side of the line they occurred. The report resolves this.

Accident types and injuries

Pomona questions

I was in a pile-up in the 57/60 merge. How do insurers decide who pays?

They reconstruct the order of impacts using damage, statements and any dashcam or truck telematics data. Fault is often divided among several drivers under California’s comparative negligence rule. See multi-vehicle accidents.

A big rig on the 60 sideswiped me. What should I collect?

The tractor’s USDOT number, the carrier name on the door, the trailer number, the driver’s name and the police report number. Commercial carriers must keep driver logs and maintenance records, and a prompt written preservation request is important. See truck accidents.

How do I get a Pomona PD report?

Through the Pomona PD records unit, with the report number or date and location. Involved parties may request copies in person or by mail.
