North Carolina regulates portable breath tests (PBTs), sometimes referred to as the “breathalyzer,” through specific administrative rules and statutory provisions. Law enforcement officers regularly rely on alcohol screening devices to assess whether a driver has consumed alcohol and may be part of the “arrest decision” related to probable cause. To better ensure reliable readings, the Department of Health and Human Services (DHHS) requires that approved devices be calibrated and verified for accuracy on a regular basis. Deviation from the rules is problematic at best and can, in some circumstances, raise doubt about whether a reported BAC reflects the true breath alcohol content.

This article explains how PBTs fit into North Carolina’s regulatory framework and why calibration rules are important. It references 10A NCAC 41B .0503 and related guidelines for monthly checks, breath simulator solutions, and ethanol gas canisters.
