Breathalyzer in North Carolina: AlcoSensor FST Explained

by Carolina Attorneys

In North Carolina, some people refer to the Alco Sensor FST as the “breathalyzer” or “PBT” (portable breath test). It is is a handheld breath alcohol screening device used by law enforcement on scene to confirm the consumption of alcohol. If you’ve been charged with driving while impaired, it’s a legitimate question to ask: Is the breathalyzer on the side of the road reliable?

Both the Alco Sensor FST and the EC/IR II (products of the Intoximeters corporation) detect the presence of ethyl alcohol (ethanol) in breath using an electrochemical fuel cell. Under N.C.G.S. 20-16.3, the Alco Sensor FST is approved for roadside screening. A positive or negative indication for alcohol may be considered when determining whether there is probable cause to arrest.
