OPERATING WHILE INTOXICATED (OWI)

Michigan law prohibits a driver from operating a vehicle upon a highway or public road while intoxicated. Operating while intoxicated is defined as operating while under the influence of alcohol, a controlled substance, or a combination of alcohol and a controlled substance. Michigan has a per se DUI statute that prohibits a person's blood alcohol content (BAC) from being at .08 or higher and operating a motor vehicle.

OPERATING WHILE VISABLY IMPAIRED (OWVI)

Michigan law prohibits a driver from operating a vehicle when a person's ability to operate is visibly impaired. If a driver refuses to submit to a chemical test, the state will file an OWVI charge. In OWVI cases, the prosecution bears the burden of proving visible impairment beyond a reasonable doubt. The defendant's driving pattern, physical characteristics and any field sobriety tests will be used to prove intoxication.

UNLAWFULE BODILY ALCOHOL LEVEL/CONTENT

Michigan law prohibits a driver from operating a vehicle when their BAC is .08 or higher. The state proves this charge via chemical testing.
