The accuracy of the breathalyzer is widely recognized by law enforcement. It is so accurate that it is not recommended by DUI lawyers as the first choice method for measuring blood alcohol levels. They advise giving a urine sample over the breathalyzer because the test is more likely to be in the drivers favor. The best way to prevent driving while intoxicated is to know how many ounces of alcohol it would take to render a level over the legal limit.
