Under Michigan's impaired driving law for drivers under 21, a person is considered to have violated the law if their bodily alcohol content (BAC) is equal to or above what value?

• A. 0.02
• B. 0.05
• C. 0.08
• D. 0.17

Answer: (A)

Under-21 drivers in Michigan face a zero-tolerance standard for alcohol: any detectable amount in the bloodstream is a violation. The law sets the threshold at 0.02% BAC, so if a young driver has 0.02% or higher, they’re considered impaired by the law. This is intentionally stricter than the adult limit, which is 0.08% BAC, and even higher thresholds like 0.05% or 0.17% aren’t the standard for underage drivers. The idea is that even small amounts of alcohol can affect judgment and driving ability in young people, so the legal limit is kept very low to discourage any drinking and driving among those under 21.
