VIDEO: Five people were injured, four of them severely, when an AMR ambulance and two cars collided Thursday on Kearny Villa Road.
A San Diego Fire-Rescue spokesperson said four of the victims suffered major trauma in the crash.
Investigators say an Infiniti coupe with two male passengers was heading northbound when it crossed into oncoming traffic and hit the ambulance head on.
The ambulance then hit a Hyundai sedan and all three cars ended up on the west side of the roadway. A male and female passenger in the ambulance were both injured. Neither were patients being transported by the ambulance. The driver suffered a brain bleed and fractured ankle, and the passenger suffered a broken forearm.
The lone occupant of the Hyundai, a 57-year-old man, suffered a broken wrist.
Firefighters had to cut away the roof of the Infiniti to reach the 21-year-old driver and 20-year-old passenger inside.
