A traffic collision occurred today on the southbound lanes of U.S. Highway 101 (US 101) at the State Route 12 interchange in Santa Rosa, CA, during the morning commute. The incident involved five vehicles, including a blue Honda CRV, a grey Hyundai Ioniq, and two dark-colored SUVs associated with a Toyota vehicle group.

The collision led to lane closures in lanes one and two, causing significant traffic congestion and delays for motorists. Emergency traffic management units were dispatched to the scene to control traffic flow and facilitate the clearing of the roadway.

As responders worked to manage the situation, some vehicles were reported to be blocking the middle lane, which contributed to the traffic backup. A tow truck was called to assist with the removal of the blue Honda CRV involved in the collision.
