A rollover crash on an Orange County freeway left eight firefighters hospitalized Thursday night.
The crash occurred in Irvine on the 241 toll road near SR-133 shortly before 7 p.m., according to the California Highway Patrol.
Authorities said a ladder dropped on the road forced the oncoming truck to swerve away from the object. The maneuver caused the vehicle to strike a guardrail and overturn.
Eight firefighters were inside the truck at the time. Authorities said they were crews who had been battling the ongoing Airport Fire in Trabuco Canyon.
The collision left six firefighters with serious injuries and two with minor injuries, CHP said. They were all airlifted to a local hospital for emergency treatment.
Sky5 video showed the overturned fire truck blocking highway roads and a large amount of debris scattered across the roadway.
No other vehicles were involved in the crash. The vehicle belonged to the Orange County Fire Authority Santiago Hand Crew.
The northbound lanes on the 241 are shut down and the northbound on-ramps on SR-133 are closed at Irvine Boulevard.
