Firefighters treated two people after their vehicles collided on Grand Avenue and Baseline Road Wednesday morning, causing two more vehicles and a traffic signal to be damaged.
One of the occupants of the vehicles involved in the initial crash was found unconscious when firefighters arrived, meeting trauma center criteria. The occupant was transported by a ground ambulance to an area trauma center for treatment while the second victim was taken to a local hospital, said Richie Licon, inspector with the Los Angeles County Fire Department.
The extent of injuries was not disclosed.
Firefighters were dispatched at 9:26 a.m.
A car southbound on Grand Avenue, for unknown reasons, struck an eastbound car on Baseline Road. The southbound car then jumped the median dividing Grand Avenue, knocking over a traffic signal and striking a third car, said Sgt. Chris Stabio of Glendora Police.
The car, waiting to turn west onto Baseline from northbound Grand, and an additional car were struck by the falling traffic signal, Stabio said.
The cause of the initial crash is still under investigation, Stabio said.
