A traffic collision involving three vehicles occurred today on the westbound lanes of Interstate 10 (I-10) at the State Route 57 South interchange in Pomona, CA. The incident, reported shortly after noon, involved a blue Tesla, a white sedan, and an unknown vehicle, which blocked the third lane and caused significant traffic disruptions.

Emergency response units, including multiple California Highway Patrol (CHP) units, were dispatched to the scene to manage the situation. The vehicles were towed from the area, but lane closures resulted in delays for drivers. A SigAlert was issued for the four and five lanes, indicating a 30-minute delay as traffic began to back up.

By approximately 1:54 PM, all lanes were cleared, and traffic flow was restored. However, motorists experienced congestion during the busy afternoon commute due to the earlier blockage. The prompt response from CHP and towing services helped alleviate the situation, allowing for a return to normal traffic conditions.

Drivers in the Pomona area are advised to remain cautious and aware of potential residual delays as traffic resumes. The CHP continues to monitor the situation to ensure the safety and efficiency of travel on this busy corridor.
