The terms "DWI" and "DUI" are used in Michigan and elsewhere in the United States. This is because the terms are very broad, which has led some police and prosecutors to believe that people could get away with driving while intoxicated. However, this is not the case under Michigan law. OWI is an acronym for operating while intoxicated, and the penalties for this offense are the same as those for driving while intoxicated.
Michigan law defines OWI as operating with a BAC of 0.08% or higher, controlled substances in the body, or under the influence of liquor/substance. In 2003, the previous BAC limit of 0.10 was lowered to 0.08 and the presumption of being sober was taken away. This means someone can be convicted of OWI even if their breath test is lower than 0.07 grams %.
In Michigan, OWI is a crime that a person can be charged with if they are under the influence of alcohol or drugs. The law has changed to make it possible for a person to be charged with OWI even if they are not using alcohol. The requirement to prove that a person is impaired while driving remains the same, but there is a lesser offense of operating while visibly impaired. A person who is impaired by alcohol is considered to be "under the influence."
When the federal government began threatening states to pass tougher impaired driving laws in the late 1940s, their leverage was withholding federal highway funding. States began the process of re-drafting their laws. Later, NHTSA was made a part of the federal DOT, in 1970, and major changes to highway safety legislation began to occur.

States like Georgia only criminalize "motor" vehicles, and not all the other means of "carriage." Cross the state line from Georgia to Tennessee, though, and riding a horse while drunk will be a DUI crime in the Volunteer State.
