In Michigan, a driver whose license was revoked for two or more alcohol-related convictions can regain driving privileges by requesting a hearing with the Michigan Secretary of State's Office of Hearings and Administrative Oversight (OHAO). After the minimum revocation period — usually 1 or 5 years — the driver must prove by clear and convincing evidence that their alcohol or drug problem is under control and likely to stay that way. Most successful first hearings result in a restricted license with an ignition interlock device, followed by full restoration after at least one violation-free year.
