If you’ve been charged with impaired driving in North Carolina, understanding alcohol testing devices can help you navigate your situation. From roadside screenings to evidentiary breath tests, these devices are commonly used by law enforcement in cases involving driving while impaired. Each has specific procedures, limitations, and legal considerations. That’s one reason we it’s a good idea to consult with an experienced attorney if you face DUI charges.
What Is the Difference Between Portable Breath Tests (PBTs) and Evidentiary Breath Testing (EBT) Devices in North Carolina?Roadside PBTs, like the AlcoSensor FST, are used to help establish probable cause for arrest but are generally not admissible in court to prove impairment by numerical reading or value. Evidentiary Breath Tests, such as those conducted on the Intoximeter EC/IR II, provide results that can be introduced as evidence in court. The key distinction lies in the admissibility and purpose of the test.
Can the Results of a Roadside Breath Test (PBT) Be Used Against Me in Court?No, PBT results cannot be used to prove a driver's BAC in court. However, they can support an officer’s decision to make an arrest based on probable cause. Challenges to the officer's interpretation of PBT results and proper calibration of the device, together with standardized field sobriety tests, and other possible indicators of impairment, can in some circumstances form part of a defense strategy. Clearly, each case is different. Consult with legal counsel regarding the specifics of your case. Check out the North Carolina DWI Quick Reference Guide.
