What is the difference between a Breathalyzer and a field sobriety test?

A Breathalyzer test is an instrument used by law enforcement to measure a person’s blood alcohol content (BAC). It is the most accurate way to measure a person’s BAC and is usually done at the side of the road. The Breathalyzer works by measuring the amount of alcohol present in the lungs when a person exhales. The result of a breath test can be used as evidence of impairment in Minnesota. A field sobriety test is a physical test that officers may require a person to perform to determine whether they are impaired. Field sobriety tests are commonly conducted at the side of the road and involve activities such as walking in a straight line or standing on one leg. Field sobriety tests are not as accurate as a Breathalyzer and can’t measure a person’s exact BAC. However, the results of a field sobriety test can be used to testify that a person was impaired in court. In summary, the difference between a Breathalyzer and a field sobriety test is that a Breathalyzer test measures a person’s exact blood alcohol content, while a field sobriety test is used to determine whether a person is impaired. Both of these tests are used by Minnesota law enforcement to enforce DUI laws.
