Is a third DUI a felony in Pennsylvania?

Last updated October 4, 2026.

Sometimes. A third DUI within 10 years is a third-degree felony when the new offense involves a blood alcohol level of 0.16% or higher, drugs, or a refused breath test or warrant blood test. At the lower tiers a third offense is still a misdemeanor, first degree for the high rate tier and second degree for general impairment, but a fourth offense is a felony at every tier.

The grade matters because it sets the maximum prison term, the fine ceiling and the license suspension. Below is the grading chart, how Pennsylvania counts prior offenses, and what changed with Deana's Law and Act 58 of 2025. For first offenses, see our main DUI defense page. Second offenses are covered on our page about the second offense DUI.

How is a third or fourth DUI graded?

Grading is set by 75 Pa.C.S. 3803 and the mandatory minimums by 3804. "Prior offenses" here means prior DUI convictions counted under 3806, explained below.

Grades: 3803(a)(2) and (3), (b)(3) and (b)(4.1). Minimums: 3804(a)(3), (b)(3) and (4), (c)(3).

The grade then sets the ceiling. Under 18 Pa.C.S. 1104 and 1103, a second-degree misdemeanor carries up to 2 years, a first-degree misdemeanor up to 5 years, a third-degree felony up to 7 years and a second-degree felony up to 10 years. Maximum fines under 18 Pa.C.S. 1101 are $5,000, $10,000, $15,000 and $25,000 for those grades. Our chart of maximum penalties for each grade of crime puts those ceilings next to the rest of the criminal code.

Are there other ways a DUI becomes a felony?

Yes. The grading statute adds several routes that do not depend on a fourth offense:

• Any DUI by a person previously convicted of homicide by vehicle while driving under the influence is a third-degree felony (3803(a)(3)).
• A DUI with a passenger under 18 in the vehicle is a first-degree misdemeanor with no more than one prior offense, and a third-degree felony with two or more prior offenses or one prior 3802(h) conviction (3803(b)(5)).
• Since Act 58 of 2025, a prior conviction for DUI following diversion under 3802(h) can raise the grade. For example, a highest-tier, drug or refusal DUI with one prior 3802(h) conviction is a third-degree felony (3803(b)(4.1)(i.1)), and with two prior offenses, one of them under 3802(h), it is a second-degree felony (3803(b)(4.1)(iii)).

How does Pennsylvania count prior offenses?

Under 75 Pa.C.S. 3806, a prior offense is a DUI conviction with a sentence imposed, an adjudication of delinquency or another form of preliminary disposition, entered before sentencing on the new case. It includes the former DUI statute, section 3731, and substantially similar offenses in other states. For grading and penalties, the prior offense must have occurred within 10 years before the date of the new offense, or on or after that date. The court counts the priors at sentencing, and two offenses sentenced on the same day count as priors to each other.

ARD changed in 2025. The Supreme Court of Pennsylvania's May 2025 decision in Commonwealth v. Shifflett led the General Assembly to remove ARD from the 3806 definition in Act 58 of 2025. Instead, a new DUI within 10 years after completing ARD is charged as its own offense, DUI following diversion, under 3802(h), and the penalty sections treat a first 3802(h) offense like a second offense. If the ARD was completed more than 10 years before the new offense, a prior 3802(h) conviction counts as a prior offense for the underlying DUI (3806(b)(4)).

Whether an old case truly counts, including an out-of-state conviction, is worth checking in every repeat DUI. Our page on prior drunk driving convictions explains how we review them. Drivers whose earlier case was in another state should also read what happens when an out-of-state driver gets a Pennsylvania DUI.

What did Deana's Law change?

Act 59 of 2022, which the act itself says may be referred to as Deana's Law, made three changes that apply to repeat cases:

• A highest-tier, drug or refusal DUI with three or more prior offenses became a second-degree felony; before, two or more priors meant a third-degree felony at most.
• A DUI sentence for a person with two or more prior offenses must be served consecutively to any other sentence, except where offenses merge by law (3804(c.2)).
• The Pennsylvania Commission on Sentencing must provide a sentencing enhancement for highest-tier, drug or refusal DUIs with four or more prior offenses (3804(c.3)).

Act 58 later extended the consecutive-sentence rule to people with one prior 3802(h) offense.

What happens to my license?

PennDOT suspends for 12 months after a second-degree misdemeanor DUI and for 18 months after a first-degree misdemeanor or a second or third-degree felony (75 Pa.C.S. 3804(e)(2)). Getting a license back after a repeat DUI requires an ignition interlock on the vehicles you will drive (75 Pa.C.S. 3805). An interlock license may let you drive during part of the suspension; see driving during a DUI suspension and the new interlock license.

Can a third-offense charge be reduced?

The district judge cannot reduce or change DUI charges at the preliminary hearing without the prosecutor's consent (75 Pa.C.S. 3812). The mandatory minimums also bind the sentencing judge, since the sentencing guidelines may not supersede them and the Commonwealth may appeal a sentence below them (3804(g) and (h)).

That leaves the real work in the evidence: whether each prior qualifies by date and type, whether the blood alcohol result is reliable and was taken in time, and whether the stop and arrest were lawful. State law bars ARD after a DUI conviction or ARD within 10 years, so it is generally not an option when a case is graded as a third offense; see who is eligible for DUI ARD.

In Delaware County, the District Attorney also runs a voluntary 30-month Drug Treatment Court for county residents with non-violent charges and substance use or co-occurring disorders. Its Track II is for higher-level offenders who enter a negotiated guilty plea and serve intermediate county punishment, but the DA lists serious DUI charges among the offenses that can disqualify an applicant, so eligibility has to be checked case by case. The sentencing alternatives the statutes allow, such as house arrest or inpatient treatment, are covered in whether treatment or house arrest can replace jail for a second DUI.

What changes the answer?

• The dates of the earlier offenses. A prior counts for grading and penalties only if it occurred within 10 years before the date of the new offense, or on or after that date (75 Pa.C.S. 3806(b)(1)). An offense 11 years back drops out of the count.
• The test result or a refusal. The tier decides whether a third offense is a second-degree misdemeanor, a first-degree misdemeanor or a felony. The reliability and timing of the test matter for that reason; see the two-hour rule for DUI tests.
• Who was in the car. A passenger under 18 can make even a case with two priors a felony (3803(b)(5)).
• Whether an earlier case ended in ARD. After Act 58 of 2025, ARD is no longer a prior offense under 3806, but a new DUI within 10 years of completing ARD is charged under 3802(h), and prior 3802(h) convictions raise later grades.
• Whether the earlier cases were out of state. Substantially similar offenses in other states count under 3806(a), so the old statute and record have to be compared with Pennsylvania's.
• Whether the assessment finds a need for treatment. A full drug and alcohol assessment is required when there is a prior offense within ten years (75 Pa.C.S. 3814(2)), and its findings shape any probation conditions (42 Pa.C.S. 9763(c)).

For example: how the dates and the tier decide the grade

Here is a hypothetical. A driver has DUI convictions for offenses in 2018 and 2023 and is arrested in Delaware County in 2026 with a blood result of 0.11%. Both earlier offenses fall within 10 years of the new one, so this is a third offense in the high rate tier: a first-degree misdemeanor with at least 90 days, a fine of $1,500 to $10,000, an 18-month suspension and an interlock before restoration. If the result had been 0.17%, or if the driver had refused a breath test, the same case would be a third-degree felony with at least one year.

Now change one date. If the first offense had happened in 2015 instead of 2018, it would fall more than 10 years before the 2026 offense and would not count, so the new case would be graded and sentenced as a second offense. That is why the exact offense dates on the old dockets come first in any repeat case. This example is only an illustration; every case depends on its own facts.

What mistakes do people make with a repeat DUI charge?

• Assuming every old case counts. Dates, the type of disposition and out-of-state equivalence all have to be checked.
• Assuming an old ARD counts as a prior. Since Act 58 it does not under 3806, although 3802(h) may apply instead.
• Expecting the district judge to lower the charge. The judge cannot reduce DUI charges at the preliminary stage without the prosecutor's consent (3812).
• Driving during the suspension. Driving while suspended for a DUI brings a mandatory jail term of its own (75 Pa.C.S. 1543(b)(1)).
• Skipping the evaluation and assessment. The court cannot impose probation on a first, second or third offense until the assessment is done (42 Pa.C.S. 9763(c)(1)).
• Waiting to get the old records. Certified dockets and sentencing orders from earlier cases can take time to obtain, especially from another county or state.

What should I do this week?

1. List every earlier DUI or diversion with the date of the offense, the county or state, and how it ended.
2. Gather any paperwork from those cases, including sentencing orders and PennDOT letters.
3. Note your test result or whether you refused.
4. Write down who was in the car, especially anyone under 18.
5. Do not drive on a suspended license, and keep every PennDOT notice.
6. Get a lawyer involved before the preliminary hearing; the steps are laid out in what happens after a DUI arrest in Delaware County.

Frequently asked questions

Does a DUI from another state count as a prior offense?

It can. Section 3806 includes offenses in other jurisdictions that are substantially similar to a Pennsylvania DUI, so the out-of-state statute and record have to be compared before the count is settled.

Can a third DUI end in house arrest instead of jail?

For a first, second or third offense, the court may impose probation with restrictive DUI conditions, such as house arrest with electronic surveillance, inpatient treatment or work release, but only after a drug and alcohol assessment (42 Pa.C.S. 9763(c)). The mandatory minimums still have to be satisfied, which our page on treatment and house arrest options explains.

Where is a felony DUI heard in Delaware County?

Like other cases, it starts at the district court for the place of the stop, then moves to the Court of Common Pleas in Media. Our guide to what to expect at the Delaware County Courthouse covers arraignment, motions and sentencing there.

Will the sentences run at the same time?

Not if you have two or more prior offenses. Deana's Law requires the DUI sentence to run consecutively to any other sentence, except where offenses merge by law (3804(c.2)).

Is ARD possible on a third offense?

Generally no. The DA may not submit a DUI for ARD after a DUI conviction or ARD within ten years, apart from a narrow exception for an earlier first general impairment charge (75 Pa.C.S. 3807(a)(2)(i)).

How is bail set on a felony DUI?

Bail is decided at the preliminary arraignment under the same statewide rules as any other charge, considering factors such as the charge, record and ties to the community. Our page on how bail works in Pennsylvania explains the types of release.
