During a traffic stop, if a law enforcement officer suspects you are under the influence of alcohol or drugs, you may be asked to perform one of the three standard field sobriety tests. The three standard tests are the walk-and-turn test, horizontal gaze nystagmus test and the one-leg stand test. However, according to a study by the National Highway Traffic Safety Administration (NHTSA) these tests are not always accurate. If you are charged with an OWI, it is advised that you contact an experienced attorney in order to challenge the results of your field sobriety test, breathalyzer test and chemical test(s). At Welch & Schmeiser Criminal Defense Group, we take a science-based approach to defending OWI cases. We routinely aid our clients in avoiding the grave impacts a Wisconsin OWI conviction entails.
