PASADENA — A fire engine responding to a medical emergency collided with a car late Saturday, sending two firefighters and two civilians, including an underage driver, to the hospital, authorities said.

The crash was reported about 11:15 p.m. at Corson Street and Craig Avenue.

The two injured firefighters suffered apparently minor injuries, Pasadena Fire Department officials said in a written statement. They have since been released from the hospital.

The two civilians — a 15-year-old driver and a young man who was riding as a passenger — suffered more serious injuries, including broken bones, fire department spokeswoman Lisa Derderian said. The injuries did not initially appear to be life-threatening.

“(Firefighters on Engine 32) were en route to a medical call with lights and sirens, heading southbound on Craig,” Derderian said.

After coming to a stop at the intersection, the engine proceeded through a red light, she said.

“A Chevy Malibu was heading eastbound on Corson and broad-sided the engine,” Derderian said.

The front of the Malibu struck the rear portion of the fire engine, injuring two of the four firefighters on board, officials said.

It was not clear Sunday if the young driver of the car would face criminal prosecution through the juvenile court system once the police investigation was complete, Pasadena police Lt. Diego Torres said.

The front of the Malibu was completely caved in, Derderian said, and there was “significant” damage to the fire engine.

“Until a mechanic can look at it… we won’t know the full extent,” she said. “It was leaking fluids. It had to be towed away.”

Another fire engine was immediately dispatched to handle the original medical call Engine 32 had been responding to, officials said.

A reserve engine was brought into service to replace the damaged Engine 32, so the fire department remains at full force, Derderian said.
