Human Factors; Procedure
Ramp cleared us to push for spot 1XX on ramp short of taxiway 1. Upon completion of the After Start Checklist; ATC clearance instructed us to taxi to runway XXR via Taxiway 2 short of taxiway 3. After reading back the taxi instructions; Captain cleared the left side of the aircraft's path as I cleared the right side. As he powered up to make our way out of the ramp area before reaching taxiway 1; I noticed a grey airport operations vehicle approaching from right to left on the service road at a high speed. I immediately told Captain to watch out for the car as it did not appear to be slowing down. He did not hear me the first call; so I said it again and instructed him to stop for the high speed car now about to pass directly in front of us. Captain immediately got on the brakes to stop the aircraft as the port car finally noticed we were taxiing out and slammed on his brakes swerving to the right to avoid a collision. I then told ground control of the car cutting us off informing him of the cars color and identification number. He then told us that they will take care of it and gave us taxi instructions once again for the departure runway.
After completing the after start checklist and beginning our taxi; FO warned me a car was approaching quickly and was not stopping. The car swerved to avoid us hitting him and I abruptly applied the brakes. After bringing the airplane to a stop; I called the flight attendants to see if there were any injuries. I was told there were none. After telling the ground controller what had happened; we continued our taxi. I made a pa at cruise altitude informing the passengers what had occurred. About three hours into the flight; I was informed that a Flight Attendant injured herself when she fell into the galley divider from the hard braking. I then informed dispatch and they called med link on my behalf. After arriving in ZZZ1; I contacted the duty manager. The car was a gray airport operations vehicle.
Flight crew reported an airport operations vehicle failed to yield to their taxiing aircraft; requiring the Captain to brake suddenly to avoid a collision.
