According to police, the crash occurred when a Hyundai Elantra operated by a 48-year-old Mashpee woman was stopped in the westbound lane waiting to turn left onto Currier Road. A Centerville-Osterville-Marstons Mills (COMM) Fire/Rescue ambulance approached westbound with emergency lights and siren activated bound for Falmouth Hospital. As the ambulance passed, the Elantra turned left into the ambulance.

The operator and sole occupant of the Elantra and the occupants of the COMM ambulance, a patient and 3 paramedics, were all transported to Falmouth Hospital by Falmouth Fire/Rescue ambulances. All injuries are reported to be not life threatening.

Hoover noted the initial crash happened just before 3 a.m. just North of Red Bluff in Tehama County, on Jellys Ferry Road at the Sacramento River crossing.

"They veered off the roadway and went airborne over the bridge and struck one of the support beams," he said.

The 18-year-old driver was killed.

"The vehicle rolled, one party was ejected and was killed on impact," Hoover said.

The passenger, who law enforcement have identified has 19-year-old Charles Sorell was flown to Mercy Medical Center in Redding with major injuries.

Hoover added both teens were not wearing their seat belts.

Jake Bushey, an officer with CHP, was already on the scene of the initial crash. He watched has an ambulance and the first CAL FIRE engine came across the bridge.

He soon realized the portion of the damaged bridge was not going to hold. However, he could not stop the second CAL FIRE engine in time.

He says it was discovered that the pumper truck was on fire.

The fire was limited to one truck, mostly in the engine. Fire investigators believe an apparent electrical malfunction was to blame for the fire.

There was a lot of smoke in the garage and the fire took about 30 minutes to control.

Farmington Service, LLC helped to pull the truck out of the fire hall, preventing further damage. No damage was caused to the fire house or any other trucks.

Chief McAdoo says 27 volunteers from the department responded. Some had to be directed away from the scene to keep calm.
