Human Factors
During taxi in we entered the ramp from the south north bound for gate XX. While abeam XX1 the Captain had spotted our gate and I was looking out the right side clearing out wing tip. I looked over to the Captain's side and saw headlights going under our airplane from the left side. I immediately tip the Captain 'Stop; Stop; Stop!'He slammed on the brakes and we stopped the airplane. The truck off our left continued and almost ran into the left side of our nose wheel. I personally believe the driver was on his phone or was distracted and almost collided with us.I immediately reported this truck to ramp control. The truck reversed and drove away under the terminal the opposite direction he was traveling (in an attempt to hide).I checked with the FAs that all were sitting down and that everyone was okay. No damage to the aircraft resulted nor any passenger or crew member was injured.
