Breathalyzer/BAC Tests in Ann Arbor

When a person is pulled over on suspicion of drunk driving, an officer will attempt to establish probable cause, usually by performing a blood alcohol content test. BAC tests, including Breathalyzer tests and chemical blood tests, utilize chemical analysis to estimate the amount of alcohol a person has consumed and whether or not they may be intoxicated. The standard measure of intoxication in Michigan is 0.08%, though persons with a BAC under 0.08% may still be convicted of Operating While Intoxicated.

Types of BAC Tests Used in Ann Arbor DUI Cases

There are three main types of chemical tests which can be used to determine blood alcohol content: breath tests, blood tests, and urine tests. Breath tests are the most convenient, and are often done roadside to establish probable cause for arrest and then either repeated at the police station or verified using a medically supervised blood test.

Roadside breath tests are known to be very unreliable and although they can be used to establish probable cause to arrest a suspect on suspicion of drunk driving, they are inadmissible in Ann Arbor courts. It is critical to keep track of everything said and done by an officer while administering the roadside test, because mistakes made during calibration or administration of the test can help later on during trial.

If your blood alcohol content registers at 0.08% or above, you are assumed to be intoxicated and can be lawfully convicted of drunk driving. Commercial license holders are only permitted to drive with a BAC below 0.04%, however, and persons under the legal drinking age of 21 cannot have a BAC over 0.02%.

Refusing to Take a Breath Test in Michigan

Though roadside breath tests cannot be relied upon to provide accurate results, it is still illegal not to take one if lawfully requested by a police officer. When you get a driver’s license in Michigan, you consent to breath tests, and there are serious penalties for refusing to submit to an officer’s request for a BAC test. If you refuse a roadside test, your license could be suspended for 2 years, and refusal of the test will still likely give the officer probable cause to arrest you for DUI.

Contact an experienced lawyer right away if you are asked to submit to a breath test, and don’t speak to police before you are able to consult an attorney.
