About This Document

Federal Register notice: This notice amends the Model Specifications for evidential breath testing devices published in 1984 and updates the list of conforming products. Recent trends indicate that the states are lowering the alcohol levels that indicate drunk driving (e.g., “zero tolerance” laws for underage offenders). Moreover, these specifications address comment received in response to a Department of Transportation Notice of Proposed Rulemaking published in the Federal Register on December 15, 1992 (57 FR 59382). The Model Specifications and the Conforming Products List set forth here reflect new lower evaluation thresholds for devices to measure breath alcohol, to better reflect the range of critical measurements during actual use.
