Is a DUI a Misdemeanor or Felony in Pennsylvania?

In Pennsylvania, a DUI is usually a misdemeanor, but whether it stays a misdemeanor or becomes a felony depends on your blood alcohol content, how many prior DUI convictions you have within the past ten years, and whether anyone was seriously hurt. So the honest answer to whether a DUI is a misdemeanor or a felony in Pennsylvania is: it depends on the tier and the count. A first offense with a BAC just over the limit is the mildest category the state recognizes. A fourth offense, or a third offense at the highest BAC level, is a felony.

The Three BAC Tiers That Drive Grading

Every Pennsylvania DUI falls into one of three tiers, and the tier is the starting point for figuring out the grade of the charge.

The last item matters. Refusing a blood or breath test puts you into the Highest BAC tier for sentencing, even if your actual BAC would have come back low or was never measured.³

When a DUI Is a Misdemeanor

Most Pennsylvania DUIs land somewhere on the misdemeanor ladder. The grade climbs as your BAC tier gets higher and as prior offenses accumulate.

A first offense in the General Impairment tier is an ungraded misdemeanor, the least serious criminal classification Pennsylvania assigns to a DUI. A first offense in either the High BAC or Highest BAC tier is also an ungraded misdemeanor, though the mandatory minimum jail time, fines, and license consequences are much steeper.¹

Once you have priors within the past ten years, the grade rises:

A second offense in the General Impairment tier is a second-degree misdemeanor.
A second offense in the Highest BAC tier is a first-degree misdemeanor, punishable by up to five years in prison.
A third offense in the General Impairment tier is a first-degree misdemeanor.⁴

In other words, you can rack up several DUIs in Pennsylvania and still technically be facing a misdemeanor, though the misdemeanor at the top of the ladder is serious. A first-degree misdemeanor carries a maximum of five years, which is longer than many low-level felonies in other states.

When a DUI Becomes a Felony

Felony territory begins at different points depending on which tier the offense sits in. This is where a lot of secondhand information online gets it wrong.

In the General Impairment and High BAC tiers, a DUI does not become a felony until you have four or more total convictions, meaning three or more priors. At that point, it is graded as a third-degree felony.¹

The Highest BAC tier, which also covers controlled substance cases and refusals, hits the felony line sooner. A third offense in that group (two priors) is a third-degree felony. A fourth offense is a second-degree felony.¹

Repeat offenses are not the only route to a felony. A DUI that causes serious bodily injury or death is charged separately as aggravated assault by vehicle while DUI or homicide by vehicle while DUI. Those are standalone felonies with prison terms far beyond the standard DUI grid. And if you have a prior conviction for homicide by vehicle while DUI, any new DUI at any tier is automatically a third-degree felony.¹

Quick Reference by Tier and Offense Number

Read across for how each combination is graded:

General Impairment, 1st: ungraded misdemeanor.
General Impairment, 2nd: second-degree misdemeanor.
General Impairment, 3rd: first-degree misdemeanor.
General Impairment, 4th or more: third-degree felony.
High BAC, 1st: ungraded misdemeanor.
High BAC, 2nd: same misdemeanor ladder as General Impairment at that count.
High BAC, 4th or more: third-degree felony.
Highest BAC (or controlled substance, or refusal), 1st: ungraded misdemeanor.
Highest BAC, 2nd: first-degree misdemeanor.
Highest BAC, 3rd: third-degree felony.
Highest BAC, 4th or more: second-degree felony.¹

Separate felony charges apply anytime a crash caused serious injury or death, regardless of where the case would otherwise sit on this ladder.

How a Refusal Changes the Grade

Pennsylvania’s implied consent law treats you as having agreed to chemical testing by driving on state roads. Refusing a lawful blood or breath test does two things at once. PennDOT suspends your license for at least 12 months (18 months if you have a prior refusal or DUI), with a restoration fee of up to $2,000 owed later.⁵ Separately, in the criminal case, the refusal drops you into the Highest BAC tier for grading and sentencing, whether or not your actual BAC would have supported that tier.³

That is why a second refusal, on paper a “second offense at the Highest BAC tier,” is already a first-degree misdemeanor, and a third refusal is a third-degree felony. Asking to call a lawyer before deciding, or simply staying silent after being warned, both count as refusals under Pennsylvania law.⁵

Avoiding a Conviction Through ARD

For eligible first-time offenders, Accelerated Rehabilitative Disposition is a pre-trial diversion program that avoids a criminal conviction entirely. Complete the program and the charges are dismissed, with the arrest record eligible for expungement. That means no misdemeanor and no felony on your record if you finish the terms.

The district attorney cannot offer ARD if you have a prior DUI conviction or ARD completion within the past ten years (with a narrow exception for a prior first-offense General Impairment case), if anyone other than you suffered serious bodily injury or death connected to the offense, or if a passenger under 14 was in your vehicle.⁶

One boundary worth stating clearly: if you hold a commercial driver’s license, ARD still counts as a conviction for CDL disqualification. You avoid the criminal record but you still lose your commercial driving privileges.⁷

The Short Version

A Pennsylvania DUI is a misdemeanor for most drivers most of the time. It escalates to a first-degree misdemeanor with certain repeat combinations, and it crosses into felony territory at the fourth conviction overall, at the third conviction in the Highest BAC or refusal category, or the moment someone else is seriously hurt or killed. Where you land on that grid is set by two numbers: the BAC tier and the count of DUI events in the past decade.
