San Francisco Oakland San Jose, CA, July 24, 2026 —
A major traffic disruption occurred on northbound Interstate 238 near San Leandro Tuesday morning when a big rig jackknifed, blocking multiple lanes and leading to a significant backup.
According to the California Highway Patrol (CHP), the incident involved a large truck that jackknifed on the freeway. The cause of the jackknife was attributed to the driver reportedly falling asleep at the wheel. The incident also involved a collision with a sand barrel.
The jackknifed big rig resulted in the closure of several lanes on northbound I-238, which significantly impacted traffic flow. Motorists experienced a backup stretching for approximately two miles, causing considerable delays for commuters in the area.
Fortunately, the California Highway Patrol reported that no injuries were sustained as a result of the jackknife and subsequent crash. The severity of the incident was primarily measured by its impact on traffic congestion.
Emergency crews and the CHP responded to the scene to manage traffic, clear the roadway, and investigate the incident. The exact timeline for the clearing of the lanes and the full restoration of traffic was not immediately available.
