Cheboygan, MI OWI / Drunk Driving Defense Attorney — William L. Keogh, PC




An OWI (Operating While Intoxicated) charge in Michigan is serious. Even a first offense can result in fines up to $500, up to 93 days in jail, 360 hours of community service, 6 points on your driving record, and possible license suspension. A second or third offense escalates dramatically — including potential felony charges, mandatory jail time, and vehicle immobilization.

The Law Firm of William L. Keogh, PC is based in Cheboygan and has defended drivers throughout Cheboygan County and Northern Michigan against drunk driving charges for nearly two decades. Attorney Keogh knows that breath and blood test results are not always accurate — and he knows how to challenge them.

Frequently Asked Questions

  • Will I lose my license after an OWI in Michigan?

    A first OWI conviction results in 6 points and possible suspension. A second conviction results in mandatory revocation for at least 1 year. An experienced attorney can work to minimize the impact on your driving privileges.

  • Can I refuse a breathalyzer test in Michigan?

    Michigan has an implied consent law — refusing a chemical test results in an automatic 1-year license suspension and 6 points. However, you do have the right to refuse roadside preliminary breath tests (PBTs) — those carry only a civil infraction.

  • Is a first-offense OWI a felony in Michigan?

    No. A first-offense OWI is a misdemeanor. However, a third offense within a person's lifetime is a felony, as is an OWI causing serious injury or death.
