Breathalyzers Are Most Commonly Used In Police DWI Or DUI Investigations – Are The Results Reliable?

Breathalyzer machines are the most common method used by police in impaired motorist or DWI/DUI investigations. In addition to a breathalyzer, a motorist’s B.A.C. can be determined under state law by testing blood, urine, or saliva. Still, the question of whether breathalyzer machines are accurate or foolproof remains prevalent. My response? Hardly.

A 2019 New York Times article highlighted many of the Breathalyzer’s shortcomings spurred largely, no surprisingly, by deficiencies surrounding the officers administering the tests and the police agencies responsible for its proper operation, administration and calibration.

The 2019 New York Times article titled “These Machines Can Put You in Jail; Don’t Trust Them…” undertook an in-depth look into the accuracy of Breathalyzer instruments across the country. The authors, Stacey Cowley and Jessica Silver-Greenberg, highlight, in part, that over 30,000 breathalyzer results had been thrown out in 2 states alone — New Jersey and Massachusetts — as a result of “lax government oversight” and “human error.” (Reference, https://www.nytimes.com/2019/11/03/business/drunk-driving-breathalyzer.html)

The New York Times article highlights deficiencies long trumpeted by skilled defense attorneys for decades. The article took a more comprehensive look at the problem nationwide.

What Does The Law Or Statute Require In New York?

The New York State Vehicle and Traffic Law section 1192, generally, and New York Codes, Rules, and Regulations (NYCRR) sections 59.1 through 59.9, offer guidelines concerning the Breathalyzer machine and processes for DWI arrests and chemical tests generally.

Per NYCRR, the New York State Department of Health (DOH) is responsible for the regulations, policy and processes regarding Breathalyzer instruments. The DOH provides a conforming products list of approved breathalyzer models for use by police agencies throughout the state. The DOH provides an approved list of Preliminary Breath Test devices, or PBTs. Police officers use portable breath test units in the field to preliminarily gauge a motorist’s B.A.C. However, courts cannot accept the PBT’s B.A.C. results as evidence. Instead, only the test results that show whether the motorist tested positive or negative for alcohol are considered valid. If the test is positive, it typically leads to a Breathalyzer chemical test at the police station.

Manufacturers require regular calibration of Breathalyzer instruments according to their instructions and guidelines. NYS law mandates annual calibration as a minimum standard. DOH guidelines require that police officers successfully complete training before they can administer the breathalyzer machine on a suspected impaired motorist. In NYS, state DOH issues a permit to police officers who successfully complete Breathalyzer training. However, as highlighted by a NY Times article, operator error plays a significant role in inaccuracies associated with Breathalyzer results, leading to some instances where courts throw out the results.

Common Breathalyzer Mistakes

The Breathalyzer is not a set-it-and-forget-it machine or instrument. Various factors can affect its accuracy. Some of those factors include:

• Calibration Issues: Breathalyzer machines need to be regularly calibrated to ensure they’re giving accurate readings.
• Operator Error: The person administering the test might not be fully trained or might perform the test incorrectly, meaning not in accordance with manufacturer instructions or regulatory requirements (under NYCRR)
• Motorist Medical Conditions: The motorist’s preexisting medical conditions, like acid reflux; the presence of dentures or other such medical equipment, and even the use of mouthwash, can affect or impact whether the proper air sample is being captured (e.g., mouth-alcohol vs. deep alveolar lung air) and, in essence, the resultant BAC.
• Environment Issues: RFI (Radio Frequency Issues); the presence of certain nearby local solvents; the electrical outlet used, and other factors can impact the instrument’s performance.
