Report Raises Doubts About DWI Breathalyzer Test
There is only one breathalyzer that police administer to New Jersey Drivers suspected of DWI: The Alcotest 7110 MKIII-C. But a report released today by the Seton Hall University School of Law's Center for Policy and Research raises concerns about the test.
The report, entitled "The Untestable Drunk Driving Test" concludes that "there are serious reasons to doubt the accuracy and reliability of the test..." The report also points out that the Alcotest cannot be independently evaluated because of the State's contract with its manufacturer, which prohibits anyone else from purchasing a unit, and because of the manufacturer's proprietary rights to the Alcotest, which prevent anyone from determining how it works. An analytic chemist for Seton Hall attempted to obtain the test, but the manufacturer, Texas-based Draeger Safety Diagnostics, refused to provide one.
The New Jersey State Supreme Court considered the accuracy and reliability of the Alcotest in State v. Chun, which was decided in 2008. In examining the issue, the Court referred to the report of a special master. Although the special master was not permitted to analyze the software used in the Alcotest, the software was submitted to two independent software houses that provided their own reports. The special master determined that the test was reliable, and the Supreme Court approved of the Alcotest.
It remains to be seen whether the Seton Hall Report will have any affect on the use of the Alcotest breathalyzer. As the report indicates, State v. Chun resolved many complex legal questions surrounding the test. However, it also suggests that other jurisdictions may come to different conclusions, and states that "the New Jersey Supreme Court cannot be the last word on the constitutionality of its foreclosure of individual defendants' challenge to the Alcotest in general or to the particular device used to measure their blood alcohol concentration."
