Is an OVI a Misdemeanor or Felony in Ohio? Lookback and BAC

In Ohio, an OVI (Operating a Vehicle under the Influence) is a first-degree misdemeanor for the first three convictions inside the lookback period, and becomes a felony on the fourth or fifth conviction within ten years, the sixth within twenty years, or any OVI arrest after you already have a felony OVI on your record. A single incident can also be charged as a felony, regardless of prior history, if it causes serious injury or death. Whether your charge is a misdemeanor or felony comes down almost entirely to how many prior convictions fall inside Ohio’s lookback windows.

The Lookback Windows That Decide It

Ohio counts your prior OVIs using two time windows. The default is ten years. If your last conviction is more than a decade old, a new charge is generally treated as a first offense. The second window is twenty years, and it applies in two situations: when a prior OVI involved a refusal to take a chemical test (breath, blood, or urine), that earlier offense stays on the clock for twenty years instead of ten; and the sixth-or-more offense trigger uses a twenty-year window regardless of refusals.¹

Which window applies controls whether you are looking at a misdemeanor or a felony. Three prior convictions spread across twelve years can still leave you facing a misdemeanor third offense. The same three priors packed into nine years make the next charge a fourth-degree felony.

When an OVI Stays a Misdemeanor

The first three OVI convictions within the ten-year window are misdemeanors. The first two are first-degree misdemeanors; the third is classified as an unclassified misdemeanor, but it is still prosecuted outside the felony system. Penalties climb at each step.

First Offense

A first OVI carries a mandatory minimum of three consecutive days in jail (a court-approved driver intervention program can substitute), up to 180 days maximum, fines of $375 to $1,075, a license suspension of one to three years, and six points on your driving record.¹

Second Offense

A second OVI inside ten years brings a mandatory ten consecutive days in jail (or five days in jail plus 18 days of house arrest with electronic monitoring), the same 180-day cap, fines of $525 to $1,625, a one-to-seven-year license suspension, possible 90-day vehicle immobilization, and mandatory alcohol and drug assessment with any recommended treatment. Restricted plates and an ignition interlock device are required.¹

Third Offense

A third OVI inside ten years raises the mandatory minimum to 30 days in jail, the maximum to a full year, and fines to roughly $850 to $2,750. The license suspension stretches to two to twelve years. Substance abuse counseling, an ignition interlock device, and restricted plates are mandatory, and if the vehicle used in the offense is registered in your name, the court orders it forfeited.¹

This is the last misdemeanor tier. The jump from a third-offense misdemeanor to a fourth-offense felony is one of the sharpest in Ohio criminal law.

When an OVI Becomes a Felony

Three situations push an OVI across the felony line:²

A fourth or fifth OVI within ten years is a fourth-degree felony.
A sixth or subsequent OVI within twenty years is a fourth-degree felony, even if fewer than four of those priors landed inside the ten-year window.
Any new OVI, at any point in your life, is a third-degree felony if you already have a prior felony OVI on your record. There is no time limit on this rule.

That third trigger catches people off guard. The ten- and twenty-year windows are generous enough that drivers often assume old convictions no longer matter. Once a conviction crosses into felony territory, though, it stays there permanently and locks every future OVI into felony status.

Fourth-Degree Felony Penalties

A fourth- or fifth-in-ten-years (or sixth-in-twenty) OVI carries a mandatory minimum of 60 consecutive days of local incarceration, or 60 days in prison with the possibility of an additional six to thirty months. Fines run from $1,350 to $10,500. The license suspension is three years to life, with driving privileges potentially available after three years. If the vehicle is registered to you, forfeiture is required.¹

Third-Degree Felony Penalties

When the “once a felony, always a felony” rule applies, the charge is a third-degree felony. The mandatory minimum is 60 consecutive days in prison, the court can add more time, and the total cannot exceed five years. Fines are again $1,350 to $10,500, and the license suspension is three years to life. Vehicle forfeiture, mandatory substance abuse treatment, restricted plates, and an ignition interlock device all apply.² Felony OVI cases are heard in common pleas court rather than municipal or county court.

High BAC and Test Refusal Raise the Floor

At every tier above, the mandatory minimum jail or prison time doubles if your blood alcohol concentration was .17% or higher or if you refused a chemical test. A first offense goes from three days to six. A second goes from ten days to twenty (or ten in jail plus 36 days of monitored house arrest). A third goes from 30 to 60. A fourth-degree felony goes from 60 days to 120. A third-degree felony goes from 60 to 120 as well. The high-BAC and refusal enhancement does not change the misdemeanor-or-felony classification by itself, but it compounds every other penalty.

Refusal has one more effect worth knowing. It activates the twenty-year lookback for that offense, so a prior OVI with a refusal keeps counting toward felony status twice as long as one without.

Serious Injury or Death: Felony Regardless of Priors

A single OVI incident can be charged as a felony even if it is your first, when someone else is hurt or killed. These charges run on a separate track from the repeat-offense rules.

Causing serious physical harm while driving impaired is aggravated vehicular assault, a third-degree felony with a mandatory prison term. It becomes a second-degree felony if you had a suspended license at the time, had prior OVI convictions, or had a previous conviction for a traffic-related assault or homicide offense.³

Causing a death while impaired is aggravated vehicular homicide, a second-degree felony with a mandatory prison term, and it rises to a first-degree felony with aggravating factors such as prior OVI convictions or a suspended license at the time of the crash.⁴

Underage Drivers

Drivers under 21 can be charged with operating a vehicle after underage consumption at a BAC as low as .02%. That is a separate, lower-level offense from the standard OVI statute. Once an underage driver’s BAC reaches .08% or higher, the full OVI statute applies with the same misdemeanor-to-felony structure that applies to adults.¹
