Irwindale, CA – One person was hurt after a collision involving a big rig and a Recreation Vehicle that happened early Friday morning in Irwindale, the California Highway Patrol reported.
The wreck occurred around 4:41 a.m., March 20, on the westbound Foothill (210) Freeway at the Irwindale Avenue off-ramp.
A big rig collided with a RV, causing the RV to crash through the freeway guardrail and stop in an embankment.
Los Angeles County Fire Department medical personnel responded and treated one person at the scene for minor injuries.
Investigators closed two lanes of the westbound freeway and the Irwindale Avenue off-ramp for two hours following the crash.
California remains a critical focus for commercial vehicle safety, recording the second-highest number of truck-involved fatalities in the nation. According to FMCSA and NHTSA data, the state saw approximately 12,243 large trucks involved in crashes in 2024, resulting in 321 fatalities and over 5,000 non-fatal injuries. While fatal incidents involving semi-trucks decreased by roughly 8% from a 2022 peak, the sheer mass of these vehicles—often weighing 20 to 30 times more than passenger cars—means that 70% of victims are occupants of other vehicles rather than the truck drivers themselves.
Primary crash factors identified in recent 2025 and 2026 reports include unsafe speed, distracted driving, and fatigue, with nearly half of all fatal incidents occurring on two-way, undivided rural roads.
