Technology / Radar / Pacing: Means the patrol car matches the suspected violator's speed. This is done with a calibrated speedometer or radar inside the patrol vehicle. When speed radar is used in this manner it is actually reading out the patrol vehicle's speed rather than the target speed and it is up to the officer to ensure that he is indeed matching the suspect's speed. Some jurisdictions may specify a minimum distance over which the pace must take place before it will be admitted into evidence.
