Sacramento, CA (July 29, 2026) — A box truck overturned during a multi-vehicle crash on northbound I-5 near Arena Boulevard in Sacramento on Monday, July 27.
California Highway Patrol dispatch records show the incident was reported shortly after 12:20 p.m. Later updates classified it as a four-vehicle collision and identified the overturned vehicle as a white box truck, reportedly a U-Haul moving truck.
The truck left the freeway, crossed traffic lanes, and came to rest on its side along San Juan Road beneath I-5. Sacramento fire crews worked to extricate the driver, while police temporarily closed traffic in both directions on the road below.
Heavy-duty towing equipment was requested for the box truck. Dispatch records also noted damage to freeway side rails. The roadway reopened while responders waited for towing crews.
The cause remains under investigation. We hope everyone affected by the crash receives the care and support they need.
Where the Collision Happened: Northbound I-5 Near Arena Blvd
Northbound Interstate 5 through Sacramento passes over local roads and connects with several interchanges serving the northern part of the city. The incident log placed the initial freeway response near Arena Boulevard, while later updates located the overturned truck on San Juan Road beneath the interstate.
Elevated freeway sections create additional response challenges when a vehicle leaves the main roadway. Crews may need to manage traffic both on the interstate and on the street below while checking barriers and arranging specialized recovery equipment.

Why an Overturned Box Truck Complicates a Multi-Vehicle Scene
A box truck has a taller profile and a higher center of gravity than most passenger vehicles. Once it begins to tip, its size and weight can make the resulting movement difficult to contain, particularly during a collision involving several vehicles.
The truck’s path from the freeway to San Juan Road adds another layer to the reconstruction. Investigators must determine how the initial contacts occurred, when the truck overturned, and how it traveled beyond the freeway barriers.
How This Collision Is Investigated
CHP investigators may examine damage across all four vehicles to establish the order of impact. They may also document tire marks, debris, damaged side rails, and the truck’s final position below the freeway.
Investigators can compare those physical findings with statements from drivers and witnesses. Because the box truck crossed multiple travel areas before coming to rest, reconstructing its path will be important to understanding the full sequence rather than relying only on the earliest dispatch reports.
What to Do After a Multi-Vehicle Crash
People involved in a California crash should retain photographs, towing documents, repair estimates, medical records, and insurance correspondence. In a complex incident involving several vehicles and damaged roadway infrastructure, the completed collision report may contain details unavailable during the initial emergency response.
For crashes investigated by the California Highway Patrol, reports are available through the CHP Crash Portal at crashes.chp.ca.gov or through a CHP 190 request submitted by mail or in person. The collision report is CHP 555, and CHP 190 is the request form.
The online portal fee is $22. Mail and in-person requests cost $10 per 25 pages through CHP. Reports become available after the investigating officer files them, and the portal shows when a report is ready.
Under Vehicle Code § 20012, eligible parties of interest include drivers, passengers, vehicle or property owners, parents or guardians, and legal or insurance representatives. California collision reports are not public records and are restricted to eligible parties, with no fixed public-release window.
