Irwindale, CA (March 22, 2026) – A semi-truck and an RV crashed on Friday morning, March 20, on the westbound Foothill (210) Freeway in Irwindale, triggering a SigAlert amid the morning rush hour. The incident happened at approximately 4:41 a.m. Close to the Irwindale Avenue South exit ramp. Officials stated that the RV smashed through a freeway guardrail and ended up in an embankment. Paramedics from the Los Angeles County Fire Department treated one individual on-site for minor injuries. Two lanes of the westbound freeway, along with the off-ramp, were shut down for about two hours as crews removed the wreckage. No further details have been made public. Officials are still probing the reason behind the crash, with further details to follow as they emerge. Our sympathies go out to those impacted. How Large Vehicle Crashes Affect Freeway Traffic. Collisions between big rigs and RVs can rapidly obstruct multiple lanes owing to the vehicles’ size and weight. Clearing large vehicles from roadways typically demands specialized equipment, which can extend lane closure durations. Even slight injuries may result due to the substantial impact forces generated by these vehicles. Commuters often face significant delays as traffic is rerouted to nearby exits.
