A traffic collision involving three vehicles occurred today on the northbound side of Interstate 405 (I-405) at the Roscoe Boulevard on-ramp in Los Angeles, CA. The incident involved a blue GMC pickup, a white Dodge pickup, and another white pickup, resulting in lane blockages that impacted traffic flow.

Emergency response units were dispatched to the scene to manage the situation and secure the roadway.
