(Stockton, CA) – A 28-year-old man was left in critical condition after being thrown from his vehicle during a rollover crash Sunday afternoon on Highway 4 in Stockton, the California Highway Patrol reported.
According to CHP Stockton, the man was driving a Honda Civic eastbound on Highway 4, just west of Wilson Way, at about 3:20 p.m. Sunday. CHP Stockton spokesperson Itzel Aguilar said the Civic veered to the left for an unknown reason and hit the concrete center median barrier.
Aguilar said the car flipped over multiple times, throwing the driver into the left lane of the highway. He was the sole occupant of the vehicle.
The man was transported to a hospital, where he was still listed in critical condition, according to the CHP. Investigators said they had not determined whether alcohol or drugs were a factor in the crash.
Know Your Rights After a Crash
After a serious crash, California law gives injured people and families limited time to act. Evidence like vehicle data, camera footage, and witness memories fades quickly.

Analysis of the Highway 4 Rollover Collision
In a single-vehicle rollover like this one, investigators typically work to understand why the vehicle left its lane of travel before drawing any conclusions. Under California law, drivers owe a general duty of ordinary care, codified in Civil Code section 1714(a), and a driver who falls short of that standard may be held responsible for resulting harm. Because the CHP has stated the cause of the leftward movement is unknown, no fault determination can be made at this stage.
Several statutes may become relevant depending on what the investigation reveals. Vehicle Code section 21658(a) requires that a vehicle be driven as nearly as practical entirely within a single marked lane and that lane movements be made only when they can be done safely. The Basic Speed Law, Vehicle Code section 22350, prohibits driving faster than is reasonable and prudent for the conditions. If evidence were to show a statutory violation that caused the injury, the doctrine of negligence per se under Evidence Code section 669 could allow a presumption of a failure to use due care.
In crashes involving a single vehicle, other lines of inquiry sometimes emerge, such as roadway conditions, a possible mechanical defect, or the involvement of another vehicle that was not accounted for at the scene. Should more than one party bear some share of responsibility, Civil Code section 1431.2 governs how non-economic damages are allocated according to each party's percentage of fault. Where a claim is established, Civil Code section 3333 sets the measure of compensation as the detriment proximately caused by the wrongful conduct.
What Survivors and Families Can Do
Anyone seriously injured in a crash like this should obtain a copy of the CHP collision report and preserve evidence while it is still available, including photographs of the vehicle and the roadway and the names of any witnesses. A driver involved in an injury crash must file a written report with law enforcement within 24 hours under Vehicle Code section 20008 and report to the DMV within 10 days under Vehicle Code section 16000. It is also important to keep in mind that California generally allows two years from the date of injury to bring a personal injury claim under Code of Civil Procedure section 335.1, and prompt medical follow-up protects both health and any future claim.
