Ontario, CA – Minor injuries were sustained in a multi-vehicle collision that happened Wednesday afternoon on 10 Freeway in Ontario.
Around 5:54 p.m. on March 11, California Highway Patrol officers responded to the westbound 10 Freeway near Fourth Street after receiving reports of the accident.
Ontario firefighters and paramedics responded to the scene and evaluated the parties involved in the collision. An unknown number of parties were treated for minor injuries.
The Nos. 1 and 2 lanes were closed during the investigation.
Ontario serves as a high-traffic logistics hub where safety initiatives are currently focused on reducing severe arterial and freeway collisions. According to the California Office of Traffic Safety (OTS) 2023 rankings, Ontario recorded 941 victims killed or injured, placing it 31st out of 62 similar-sized cities—a mid-tier safety profile. However, the city faces heightened risks in specific categories, ranking 13th worst for DUI-involved drivers under age 21. A catastrophic multi-vehicle crash on the I-10 Freeway in late 2025, involving a semi-truck and several passenger vehicles, highlighted the region’s ongoing struggle with high-speed, high-lethality incidents near the I-15 interchange.
Data from 2024 and 2025 indicate that unsafe speed (14%) and DUI-related impairment remain the primary factors for fatal collisions. To address these trends in 2026, Ontario is prioritizing infrastructure hardening along major corridors like Archibald Avenue and Milliken Avenue.
