Breathalyzer Error
whether or not a person is above the legal blood alcohol breathalyzer accuracy vs blood test limit to operate a motor vehicle. The accuracy of these tests is often a subject of debate, validity of breathalyzers but advances in technology have made results more reliable. Understand the legal limit While any BAC level over .08 percent is considered over the legal limit, understand that a https://www.duiblog.com/2006/06/20/breathalyzers-40-margin-of-error-is-acceptable-accuracy/ BAC determined by a breathalyzer test is only one determinant of your ability to drive, and you can be arrested for DUI if you display other symptoms of intoxication or fail a field sobriety test. Any lack of accuracy in the machine must be assumed in both a positive and negative direction, so it's as likely that your https://www.duiattorneyhome.com/questions/22-how-accurate-are-breathalyzer-tests test will show a lower than actual BAC as it may a higher than actual ratio. Determining error Breathalyzer tests make a number of assumptions about the person being tested. The ratio of blood alcohol content to breath alcohol content is assumed to be 2100:1, though the actual ratio for a person can range from 1700:1 to 2400:1 depending on factors like height and weight, sex and metabolism. Strenuous physical activity can reduce BAC by up to 25 percent, leading to inaccurate readings in some cases. Margin of error Most courts recognize a 0.1 percent error when it comes to breathalyzer tests, and many law enforcement agencies require multiple tests to fall within a certain range for a breathalyzer test to be considered as evidence of DUI. While the determinant range suggests accuracy in testing, some DUI attorneys argue that the process is flawed. In California, an arresting officer can test as many times as necessary until the breathalyzer comes up with results within a .02 percent range on two consecu

While not as accurate or reliable as blood tests, it has generally been regarded as acceptably accurate for use in DUI investigations, if administered correctly. This regard is beginning to erode, however. An example of this is the comment of Dr. Michael Hiastala, Professor of Physiology, Biophysics and Medicine at the University of Washington: Breath testing, as currently used, is a very inaccurate method for measuring BAC. Even if the breath testing instrument is working perfectly, physiological variables prevent any reasonable accuracy.... Breath testing for alcohol using a single test method should not be used for scientific, medical or legal purposes where accuracy is important. [Hlastala, Physiological Errors Associated with Alcohol Breath Testing, 9(6) The Champion 19 (1985).] A number of scientists who have conducted studies of breath-alcohol analysis have concurred with Dr. Hlastala in concluding that breathalyzer accuracy is inherently unreliable. Thus, for example, one study determined that breath readings vary at least 15 percent from actual
