What is the difference between the PBT and the breath test offered at the station?

PBT stands for Preliminary Breath Test. Generally speaking, an individual will be offered to submit to a PBT immediately after the traffic stop so that the officer can begin to determine whether that individual is DUI. Consequently, the relevance of the PBT ends there. It is merely a means for the officer to acquire the necessary cause to arrest that individual for DUI. Typically, the PBT results to not come into court as evidence against the accused due to its unreliability. The breath test offered back at the station, however, is completely different. While both instruments measure alcohol in the breath, the test back the station is for evidentiary purposes, tends to be more accurate, and the results will be used as evidence in court. Additionally, while both tests are voluntary, refusing to participate in the breath test back at the station carries with it numerous consequences.
