If you have been charged with a driving under the influence or driving while intoxicated offense in Minnesota, you will no doubt want to learn your options to defend yourself. This is certainly your right and you should always feel you have such an option. One thing that may become part of your defense is the accuracy of the evidence used against you. This includes the results of any field sobriety tests you took.
As explained by FieldSobrietyTests.org, these tests are not used or able to measure any impairment or intoxication in a person. Instead, they are simply a means to indicate that a person might possibly be impaired so that a police officer can legally place them under arrest for suspected drunk driving. This is an important distinction that drivers should know.
Also important to know is that none of the tests used are fully accurate. Even the most accurate test of all has an accurate rate of only 77 percent. The other two tests are said to be accurate only 68 percent of 65 percent of the time. Many things including a driver's age, weight and other physical health conditions may influence the results of these tests and make it difficult if not impossible for a driver to pass the these tests.
