I began a training flight with my student; and the lesson covered Short Field and Soft Field Takeoffs and Landings. I demonstrated a Soft Field Takeoff and Landing then gave the controls back to the student; who taxied back to the Hold Short line for the runway. The student made the radio call to take the runway; we both visually cleared final and the runway for any traffic; and then taxied into position. After the student was aligned with the centerline he began to bring in full power. During the takeoff roll; I noticed a white vehicle on the East side of the field approaching the Hold Short line for the mid-field taxiway. As the aircraft was beginning to liftoff; I determined that the vehicle was not going to stop at the Hold Short line; took the controls; and aborted the takeoff. The vehicle continued across the runway in front of the aircraft; I slowed down and then exited at the first taxiway. The point at which I took the controls and aborted the takeoff was just prior to the Aiming Point Markings ('thousand-footers'.)The vehicle never slowed down; except to stop while waiting for the mid-field gate to open.
A vehicle crossed the runway in front of departing aircraft at an non-towered airport and the takeoff was aborted.
