The details
Crash incidents on Interstate 80
The first collision happened on 13 October near Fairfield when a Tesla traveling east entered a CHP‑closed lane and struck a patrol vehicle, seriously injuring two officers. The driver, a 22‑year‑old from Sacramento, said he was asleep while Full Self‑Driving was engaged.
The second incident occurred on 22 October near Vallejo. A 26‑year‑old driver from San Francisco reported the vehicle was in Full Self‑Driving mode when it hit a 71‑year‑old pedestrian who was crossing the highway shoulder. The Tesla applied brakes and steered left but still struck the man.
Safety concerns raised
Both crashes have highlighted the need for continuous driver supervision when using Tesla’s supervised Full Self‑Driving system. CHP emphasized that automated assistance does not remove the driver’s responsibility to stay alert, especially in emergency‑closure zones or when unexpected pedestrians appear.
Federal investigations by NHTSA have previously identified delayed driver‑engagement warnings in similar scenarios, underscoring the importance of timely human intervention.
Regulatory context in California
California expanded its Move Over legislation on 1 January 2026, requiring drivers to change lanes or reduce speed when approaching stationary emergency vehicles, cones, flares or other warning devices. The Fairfield crash occurred within a clearly marked CHP closure, making compliance with the new rules a critical factor.
Tesla’s 2023 recall of 2.03 million vehicles to improve Autosteer safeguards adds further regulatory background, though it targeted a different system.
