"If it's only a misdemeanor, is it basically no big deal?" No. A misdemeanor DUI is still a criminal charge for driving under the influence of alcohol, drugs, or another intoxicant, but it is treated as less severe than a felony DUI. Usually that means the case does not involve a death, very serious injury, or the kind of repeat history that raises the charge to a felony. The label "misdemeanor" misleads people: it can still bring arrest, court appearances, fines, probation, license suspension, treatment requirements, and possible jail.

That matters because "misdemeanor" does not mean harmless, excusable, or easy to beat. In Hawaii, DUI cases are usually charged as OVUII - Operating a Vehicle Under the Influence of an Intoxicant - under Hawaii Revised Statutes §291E-61 (2024). A blood alcohol level of 0.08% or more can support the charge, but impairment by alcohol or drugs can also be enough. Bad roadside advice like "just refuse everything" often backfires, especially when officers also rely on driving behavior, body-camera footage, and chemical tests.

For an injury claim, a misdemeanor DUI can strongly support proof of negligence, but it does not automatically guarantee full payment. Hawaii's no-fault system under HRS Chapter 431:10C means PIP coverage usually pays first. On rural islands, longer crash response times and sudden rain squalls on mountain passes can complicate both impairment evidence and arguments about what actually caused the wreck.
