High BAC (0.17 or More) OWI in Michigan: Penalties and Defenses

A Michigan OWI with a blood alcohol content of 0.17 or more, often called “super drunk,” is a misdemeanor that can bring up to 180 days in jail and a fine of $200 to $700 for a first offense. The charge is in MCL 257.625(1)(c), and the penalties are in MCL 257.625(9)(a). The higher penalties make the test result the center of the defense.

How is it different from a regular OWI?

A regular first-offense OWI carries up to 93 days in jail and a $100 to $500 fine. The high BAC version roughly doubles the maximum jail time and raises the fine range. See our page on first-offense OWI for the comparison.

Common defenses

  • Test accuracy. The result must come from a properly maintained device or a properly handled sample. Equipment records, operator training, and procedure can all be reviewed.
  • Timing. Alcohol levels change over time, so the gap between driving and the test can matter.
  • The stop and the arrest. A stop without a lawful reason, or an arrest without probable cause, can lead to a motion to suppress evidence.
  • Reduction. If the number cannot be defended, your attorney may work toward a lower charge.
