Michigan’s High BAC, often called “Super Drunk,” is a special form of OWI that applies when the prosecution alleges a high bodily alcohol content. In Detroit, these cases are frequently driven by a breath or blood number and are prosecuted more aggressively because the statute authorizes enhanced penalties.

High BAC cases are not purely mathematical disputes. The defense must examine how the number was created, including whether the collection method, instrument, operator, and chain of custody meet legal and scientific expectations. Small procedural failures can have outsized legal consequences.

Timing matters. Chemical tests occur after driving, and alcohol absorption, elimination, and physiological variability can complicate any claim that a later test precisely reflects the level at the time of operation. The defense should consider whether the prosecution can reliably connect the test to the driving period.

Because High BAC increases leverage for probation conditions and interlock requirements, an early defense posture should emphasize litigating reliability issues, preserving video and records, and building a coherent narrative that is supported by the objective evidence.

High BAC (.17) OWI: Testing Issues Matter

Michigan recognizes a distinct “operating with high bodily alcohol content” pathway under MCL 257.625(1)(c), and the standard jury instructions address that specific allegation. The Traffic Benchbook explains that the OWI framework includes different types of Section 625 offenses, and it highlights that jury instructions differentiate OWI from High BAC and OWVI. The practical point is that the prosecution’s proof depends heavily on chemical testing, not only on officer impressions.

High BAC litigation starts with the legal prerequisites for obtaining the test. Counsel should assess whether the arrest was supported by probable cause and whether any warrant requirement applied, particularly for blood. Cases such as Missouri v. McNeely and Birchfield v. North Dakota are frequently litigated in the background of modern OWI chemical-testing practice, and Michigan courts have applied those principles in the Section 625 context.

Next comes the science and administration. The defense should review maintenance and calibration records, operator certifications, sample handling, and whether the reported result is consistent with the full test record. When breath testing is involved, the defense should scrutinize whether the instrument documented warnings or errors, and whether there were circumstances that could contaminate a breath sample.

Finally, sentencing exposure under MCL 257.625(9) is materially higher for High BAC, including a higher fine range and increased maximum incarceration compared to standard OWI. A disciplined defense can narrow the dispute to what the state can prove, rather than what it assumes the number means.
