DWI Breath Test Machines Are Facing More Scrutiny

By November 4, 2019 No Comments

An investigation has found that the portable breath tests used nationwide in DWI stops are “often unreliable,” reports the New York Times. These tests “generate skewed results with alarming frequency” for a variety of reasons, including improper calibration, “serious programming mistakes in the machines’ software,” and police departments choosing less trustworthy machines to begin with. Despite problems like this, “the tests have become all but unavoidable. Every state punishes drivers who refuse to take one when ordered by a police officer.” But the Times reports that “recognition of the tests’ problems is spreading.” For instance, in Minnesota, “a judge ruled last year that the state’s machines appeared to be rounding up results, falsely nudging some defendants over the legal limit.”
