Concord, CA (August 12, 2026) — A three-vehicle collision on Monday, August 10, resulted in a reported minor injury on eastbound State Route 4 near the southbound State Route 242 connector.
California Highway Patrol dispatch records show the incident was first reported at about 6:08 p.m.
The source does not identify the people involved.
The cause remains under investigation. We wish those affected a swift and full recovery.
Where the Crash Happened: State Route 4 at the State Route 242 Connector
The location description places the incident at a gore point near the State Route 242 southbound connector. A gore point is the area where a main roadway and an exit or connector path separate, making this a transition area rather than a conventional street intersection.
For a State Route corridor, that roadway layout means drivers may be continuing along the main route or positioning for the connecting roadway as they approach the split.
What We Know
- California Highway Patrol records described the incident as involving three vehicles.
- A complaint of pain prompted a request for medical response at about 6:17 p.m.
- Tow requests were made for a black Toyota RAV4 and a silver Toyota RAV4.
- The incident log also referenced a black Ram pickup and sport utility vehicles during the response.
How Lane Closures Affect a State Route Crash Scene
Traffic control changed as responders worked around the collision. At 6:16 p.m., California Highway Patrol records indicated that lanes 2 and 3 were blocked. By 6:33 p.m., lane 4 was still closed while the remaining lanes had reopened.
At a State Route connector area, changing lane availability can affect how approaching drivers move through the corridor. Responders must balance access for medical personnel and tow operators with the need to reopen usable lanes as the scene is cleared.
How This Crash Is Investigated
Early dispatch information can change as officers reach a crash and confirm details that callers could only provide during the initial report. That is relevant here because the first entry described an unidentified pickup and an unidentified sedan with a trailer, while later entries described a black Ram pickup, sport utility vehicles, and two Toyota RAV4s.
Investigators can compare vehicle identification, damage, photographs, final vehicle positions, and statements from those involved to establish the sequence more reliably than any one early dispatch entry. In a three-vehicle collision, that review can also help determine which contact occurred first and whether one impact led to another.
What to Do After a Car Collision
People involved in a California collision can use the completed crash report to review information documented after officers have investigated the scene. Keeping photographs, medical records, repair information, towing documents, and insurance correspondence together can also help preserve details while the report is being completed.
For crashes investigated by the California Highway Patrol on freeways, state highways, or in unincorporated areas, the California spreadsheet row lists the California Highway Patrol as the report agency. Reports may be obtained through the CHP Crash Portal at crashes.chp.ca.gov or with a CHP 190 form by mail or in person.
The report form is CHP 555, and CHP 190 is the request form. The online portal fee is $22, while mail or in-person requests cost $10 per 25 pages through CHP.
Reports are available after the officer files them, and the portal shows when a report is ready. Under Vehicle Code § 20012, a party of interest includes a driver, passenger, vehicle or property owner, parent or guardian, or legal or insurance representative. California Highway Patrol reports are not public and are restricted to parties of interest, with no fixed day window for public release.
Local Accident Reports compiles incident information from official agencies and credible local sources. Details from initial reports may be updated as official investigations conclude.
