HAYWARD, Calif. — An overturned box truck on eastbound Highway 92 created major traffic problems during the Friday evening commute, with congestion stretching back toward San Mateo after all lanes were temporarily blocked near Clawiter Road in Hayward.
The crash happened shortly before 5 p.m. Friday, September 25, 2026, just beyond the Highway 92 toll plaza. Video from SKY7 showed the box truck overturned across the roadway as emergency crews responded to the scene.
The collision caused a significant traffic backup extending westward into San Mateo, turning an already busy commute into a lengthy delay for drivers traveling across the San Mateo-Hayward Bridge.
According to the latest available report, all eastbound lanes have since reopened. However, the incident caused substantial disruption while crews worked to manage traffic and clear the overturned vehicle.
Highway 92 Crash Causes Major Traffic Delays
The crash occurred on eastbound Highway 92 at Clawiter Road in Hayward, shortly before 5 p.m.
The location is particularly important because Highway 92 connects the East Bay with the San Mateo Peninsula through the San Mateo-Hayward Bridge.
When the overturned truck blocked the roadway, traffic quickly accumulated behind the crash.
Drivers attempting to cross the bridge during the evening commute were confronted with significant delays as authorities worked to secure the scene and remove the disabled vehicle.
The resulting backup reportedly extended all the way into San Mateo, illustrating how quickly a major incident on Highway 92 can affect traffic on both sides of the bridge.
Overturned Box Truck Blocks Eastbound Highway 92
Images and video from the scene showed a box truck overturned on eastbound Highway 92 just beyond the toll plaza.
The position of the truck created an immediate obstruction for eastbound traffic.
At the height of the incident, all lanes were blocked, leaving motorists unable to continue normally through the affected section.
Emergency crews and transportation personnel worked to address the crash and restore access to the highway.
The overturned truck also required recovery operations before normal traffic could resume.
Highway 92 Lanes Have Reopened
The latest available update indicates that the eastbound lanes affected by the crash have since reopened.
That means the immediate full closure has ended, although drivers may continue to experience residual congestion after traffic has backed up for an extended period.
When a major highway is closed during the evening commute, reopening the lanes does not necessarily mean traffic returns to normal immediately.
Thousands of vehicles can accumulate behind a closure, creating secondary congestion that can take considerable time to dissipate.
Drivers approaching Highway 92 should therefore continue checking current traffic conditions before beginning their journey.
Were There Injuries in the Highway 92 Crash?
At the time of the latest report, authorities had not publicly confirmed whether anyone was injured in the overturned truck crash.
The available information confirms the truck rollover and the resulting traffic disruption, but it does not provide a verified injury count.
That means reports circulating online about possible injuries should be treated cautiously until authorities release additional information.
Traffic crashes can initially generate incomplete reports, particularly while emergency crews are still assessing the scene.
A confirmed statement from law enforcement or emergency officials would provide a more reliable account of any injuries.
What Caused the Highway 92 Accident?
The specific circumstances that caused the box truck to overturn have not been publicly established in the information currently available.
Authorities may investigate factors such as vehicle movement, road conditions, traffic patterns and other circumstances surrounding the crash.
Until that investigation produces confirmed findings, it would be inappropriate to speculate about what caused the truck to overturn or assign responsibility to a driver.
The immediate priority following the crash was clearing the roadway and restoring safe traffic movement.
Further details may emerge as authorities complete their investigation.
San Mateo-Hayward Bridge Traffic Disrupted
The crash had a particularly large impact because Highway 92 serves as a major connection between Hayward and San Mateo.
The San Mateo-Hayward Bridge carries significant commuter traffic between the East Bay and Peninsula, meaning a major obstruction can quickly create backups in both directions and on surrounding roads.
In this case, traffic was reported backed up into San Mateo after the eastbound crash.
Drivers approaching the bridge from the Peninsula side were therefore affected even though the overturned truck was located in Hayward.
The incident demonstrates how a single crash can have consequences well beyond the immediate location.
Drivers Face Residual Delays After Crash
Even though the lanes have reopened, motorists may continue encountering slower traffic as the backlog clears.
Drivers traveling between San Mateo and Hayward should allow additional time and check current conditions before entering the Highway 92 corridor.
Those approaching the area should also be prepared for changing traffic patterns if additional cleanup or recovery operations are required.
Motorists should never attempt to bypass congestion by using shoulders or entering restricted areas.
Emergency responders and recovery crews need those areas to safely reach and clear crash scenes.
Highway 92 Crash Adds to Bay Area Commute Problems
The overturned truck was not the only factor affecting Bay Area traffic during the Friday commute.
Other crashes, disabled vehicles and roadwork also contributed to delays across the region.
A Friday morning traffic report from Patch noted additional problems around the Bay Area, including a traffic hazard on westbound Highway 92 east of the San Mateo Bridge toll plaza.
Caltrans has also announced upcoming nighttime construction-related restrictions around the Highway 92 and U.S. 101 interchange in San Mateo, although those scheduled closures are separate from Friday’s truck crash. The planned work is scheduled for September 27 through October 2.
What Drivers Should Know
Anyone traveling through the Highway 92 corridor should remain alert for changing conditions.
Drivers should:
- Check current traffic conditions before crossing the San Mateo-Hayward Bridge.
- Slow down when approaching emergency vehicles or recovery crews.
- Follow all instructions from law enforcement and transportation officials.
- Avoid stopping near the crash scene unless directed to do so.
- Never use a freeway shoulder to bypass traffic.
- Allow additional travel time when congestion remains after a major closure.
Traffic conditions can change quickly after a serious crash, particularly during peak commute periods.
Highway 92 Accident Investigation
Authorities will determine the circumstances surrounding the overturned box truck.
At this stage, the publicly available information confirms the crash location, the truck rollover, the major lane blockage and the resulting traffic backup, but does not establish a detailed cause or confirmed injury count.
As the investigation continues, officials may release additional information about the crash.
Until then, drivers and members of the public should rely on verified information rather than speculation or unconfirmed social-media reports.
