The second one isn't the first one twice, and the third changes the courthouse.

The enforcement campaign that began on August 14 still has its biggest weekend ahead of it, with Labor Day on September 7 and local schools closed from Friday the fourth. If you've been through an OWI before, the thing worth understanding before that weekend is that Michigan doesn't treat a repeat as a bigger version of the first one. The jail time stops being theoretical, the license is revoked instead of suspended, and on a third the case leaves the district court entirely.

What makes it a second offense?

A prior conviction within seven years, which is a shorter window than most people assume and a longer one than they hope. What counts as a prior is broader than a Michigan OWI as well, since convictions for operating while visibly impaired, local ordinance versions of the same offense, and substantially similar offenses from other states can all put you in repeat territory. That's the part that catches people who moved here, or who resolved something years ago in a district court and never thought about it again.

What does a second conviction carry?

The number that matters most is the mandatory minimum, because a second conviction within seven years requires at least 5 days in jail or at least 30 days of community service, with jail exposure running up to one year. Add a fine of $200 to $1,000, six points, vehicle immobilization, and the probation conditions that come with an alcohol case, including testing and treatment. The maximum is rarely what happens, but the minimum is a floor rather than a starting point for negotiation, which is the practical difference between a first offense and a second.

Why is the license different this time?

Because a second conviction moves you from suspension to revocation, and those are different things. Under MCL 257.303, two convictions within seven years mean the license is revoked, which is not a pause with an end date; the minimum period is one year, or five years if there's been a prior revocation within the last seven, and when it runs out you get the right to request a hearing rather than the license itself. That hearing has a clear and convincing standard and a documented sobriety requirement, which we walk through in our guide to Michigan license restoration.

Why is a third a felony no matter how old the priors are?

Because Michigan removed the lookback for third offenses. Under the 2007 change commonly called Heidi's Law, effective January 3 of that year, prior drunk driving convictions count for life, so a conviction from 1994 and one from 2003 can combine with an arrest tonight to produce a felony charge. The offense in front of the officer might look identical to a first offense, and the charge is still a felony, which is worth reading against our comparison of misdemeanors and felonies in Michigan.

What does a third carry?

A third offense is punishable by 1 to 5 years in prison, or by probation with 30 days to one year in jail plus 60 to 180 days of community service, along with a fine of $500 to $5,000, vehicle immobilization or forfeiture, and revocation with the same minimum periods described above. It's also charged in the circuit court rather than the district court, which changes the timeline, the procedure, and the practical shape of the case, since a felony passes through a preliminary examination stage before it ever reaches the circuit judge who will sentence it.

What actually changes the outcome?

The same things that decide a first offense case, examined more carefully because there's more at stake: the reason for the stop, which we covered in our piece on why Michigan has no sobriety checkpoints, and how the testing was handled, including whether a refusal triggered the separate implied consent case. Beyond the evidence, the sentencing conversation is real, and the strongest version of it usually involves treatment that started before the sentencing date rather than after it.

There's also a route the ordinary rules close off. Michigan's DWI sobriety courts can issue a restricted license with an ignition interlock to a repeat offender who is admitted and participating, after a 45 day period, which is otherwise unavailable on a second or third offense. Admission is up to the court, not every court runs a program, and the ones that do expect real compliance. If you're facing a repeat charge, our criminal defense practice can tell you which of these is realistic where your case is filed, and the consultation is free, so call before your first court date.

Quick answers

How far back does Michigan look for a second OWI?

Seven years. A second offense is charged when there's a prior conviction within seven years, and priors can include operating while visibly impaired, local ordinance versions of the offense, and substantially similar convictions from other states.

Is a third OWI always a felony in Michigan?

Yes. Since Heidi's Law took effect on January 3, 2007, there's no lookback limit for a third offense, so convictions from decades ago still count. A third is charged as a felony in the circuit court.

Can you get a restricted license after a second OWI?

Not through the ordinary process, because a second conviction within seven years brings revocation rather than suspension. The exception is a DWI sobriety court program, where a participant with an ignition interlock on every vehicle can be issued a restricted license after a 45 day period.
