Human Factors; Procedure
We were ready to push so I grabbed the wands and raised them up and was walking to the [Vehicle Service Road] VSR. A small Air Carrier X vehicle was speeding fast on the VSR.  My arms were raised showing we were pushing. They never showed any intention of stopping; so we had to stop the push back. Training taught my class we were supposed to stop push back and not give vehicles on the VSR the X unless it was an air-start.
Ground employee reported a ground conflict between the aircraft they were pushing back and a vehicle traveling fast on the VSR.
