HAYWARD, CA — An overturned box truck on eastbound Highway 92 in Hayward caused major delays during the Friday evening commute after the crash near Clawiter Road blocked all lanes just before 5 p.m.
Video from SKY7 showed the truck lying on its side just past the toll plaza. By the time traffic updates were posted, lanes had reopened, but the backup had already stretched into San Mateo.
Crash shuts down eastbound lanes near the toll plaza
The collision happened in a heavily traveled stretch of Highway 92, where evening traffic can quickly slow when a lane closure occurs. In this case, all eastbound lanes were blocked at the scene, creating an immediate bottleneck for drivers heading toward the Bay Bridge corridor and nearby Peninsula routes.
The truck was seen overturned shortly after the toll plaza, close to the Clawiter Road exit. That location matters because congestion there can ripple quickly through surrounding freeway connections, especially during the Friday commute when traffic volumes are already high.
SKY7 video showed the truck on its side
Images captured by SKY7 showed the box truck resting on its side in the roadway. The footage made clear that the vehicle was not just disabled but fully obstructing the eastbound lanes, which explains why traffic slowed so sharply so fast.
The crash happened in daylight during the evening commute window, increasing the number of drivers affected. While the video showed the condition of the truck and the roadway, authorities did not immediately say what led to the rollover.
Backups reached San Mateo before lanes reopened
The traffic impact extended well beyond Hayward. Delays stretched all the way into San Mateo, showing how a single crash on a key East Bay freeway can affect commuters across multiple cities and counties.
Officials later said the lanes reopened, easing the immediate shutdown at the scene. Even so, the congestion had already built up by then, leaving drivers to work through slow-moving traffic long after the truck was cleared enough for travel to resume.
No injuries had been reported at the time of the update
Authorities had not said whether anyone was hurt in the crash when traffic updates were issued. That meant the public information available focused first on the roadway impact rather than on the condition of the people involved.
For commuters, the main immediate effect was the major delay on Highway 92. The lack of injury information also left open important unanswered questions about how the crash happened and whether emergency crews needed to treat anyone at the scene.
Why a single crash on Highway 92 can cause a regional slowdown
Highway 92 is one of the important links across the East Bay and toward the Peninsula, so a blocked eastbound stretch can affect far more than local Hayward traffic. When all lanes are closed, drivers have few options but to wait, reroute, or sit in growing congestion behind the scene.
The Friday timing made the disruption worse because it came during a peak commute period. In that setting, even a short-lived closure can create long lines of traffic, and recovery can take longer than the incident itself as vehicles work back through the backup.
