The ambulance was traveling eastbound on 16th Street when it collided with a white Volkswagen Cabriolet heading southbound on South Van Ness Avenue, said SFPD Commander Mikail Ali.

“We know the ambulance was traveling code three to a service call. A code three is lights and sirens,” Ali said. “They responded in that fashion, but it’s yet to be determined what the cause is.”

“There are a number of causes as to why people are involved with collisions with emergency vehicles in that manner,” Ali added. “Distracted driver is the primary cause.”

Jorge Luna, an employee at the nearby 76 gas station who witnessed the accident, said the ambulance flipped over “two or three times.”

Ambulance passengers included two paramedics sitting in the front of the vehicle and a medic intern in the back. There was only one passenger in the Volkswagen.

The two paramedics got out of the ambulance with Luna’s help, while first responders attended to the intern in the back, Luna said.

The Major Accident and Investigation team is on the scene. As of 1 p.m., police had blocked off the intersection to traffic and Muni’s 22 Fillmore line was being rerouted.
