San Leandro, CA (June 13, 2026) – A three-vehicle traffic collision caused significant delays on southbound Interstate 880 near Interstate 238 in San Leandro on Saturday afternoon. The crash was reported shortly before 2:45 p.m. and initially blocked multiple lanes of travel.
Dispatch records indicate a white Chevrolet Malibu, a white Toyota van, and a gray Honda were among the vehicles involved. Later updates identified three damaged vehicles requiring towing, including a white Tesla, a white minivan, and a gray Honda Accord. Several people were out of their vehicles following the collision.
One person involved declined medical assistance at the roadway, while dispatchers later requested information regarding the extent of injuries among those involved. Lane closures triggered a SigAlert, with lanes 1 and 2 remaining blocked for some time before all lanes reopened around 3:44 p.m.
The names of the people involved were not released in the initial report.
Investigators are continuing to examine the factors that contributed to the crash and the resulting traffic disruptions. We are thinking of those affected and wish anyone receiving treatment a speedy recovery.
What Causes Traffic Delays After a Multi-Vehicle Collision?
Multi-vehicle collisions can cause significant traffic congestion when damaged vehicles block one or more travel lanes. Even when injuries are minor, roadway space can be reduced while vehicles are moved and debris is cleared.
Traffic backups often form quickly on busy highways, especially near interchanges where many vehicles merge and change lanes. Drivers approaching a blocked section may slow down suddenly, creating additional congestion that can extend well beyond the original crash site.
The length of a delay can depend on several factors, including the number of vehicles involved, the extent of vehicle damage, and whether towing services are needed. Once vehicles are removed and lanes reopen, traffic flow may still take time to return to normal as accumulated backups gradually clear from the roadway.
