Those charged with a Massachusetts OUI based on breathalyzer test results should contest their OUI charge in court. There are many ways in which a good DUI lawyer can exclude breathalyzer evidence.

According to a news report from Denver, Colorado, hundreds of DUI cases may be affected by the discovery of problems with breathalyzer testing equipment in the lab in Colorado Springs.

Inaccuracies and defects in breathalyzer are not limited to Colorado. In February 2009, Dr. Barry Logan, head of the state crime and toxicology labs in Washington State resigned over discovery of deficiencies in the way DUI testing. Irregularities were uncovered in late summer 2007 in the state toxicology lab. A senior manager was found to have signed off on tests she did not perform. This discovery led to an investigation into other problems, including errors could have impacted 130 DUI cases. Problems with breathalyzer testing can come from mechanical problems with the breathalyzer machine, including design defects, source code errors and human error.
