Is a DUI a Felony in PA? Triggers, Penalties & Consequences

Yes, a DUI can be a felony in PA, but only in four specific situations: a driver in the highest BAC tier (0.16% or above, controlled substances, or refusal to test) with two prior DUI convictions in the last 10 years; any driver with three or more prior DUI convictions in that window; a DUI that causes serious bodily injury or death; or a DUI with a passenger under 18 when the driver has two or more prior offenses. Every other DUI in Pennsylvania is a misdemeanor.

The Four Triggers That Turn a PA DUI Into a Felony

Pennsylvania grades most DUIs as misdemeanors, with penalties scaling by blood-alcohol tier and by how many prior convictions the driver has within a 10-year lookback that runs from the date of the current offense back to the conviction date of the earlier one. The felony line sits above those misdemeanor tiers, and the grading statute names each crossing point.¹

Third Offense at the Highest BAC Tier

A driver who registers 0.16% or higher, tests positive for a controlled substance, or refuses chemical testing, and already has two prior DUI convictions within 10 years, faces a third-degree felony. This is the lowest prior-count that reaches felony grading, and it only applies at the most serious impairment tier.¹

Fourth or Subsequent DUI at Any BAC Level

Once a driver has three or more prior DUI convictions within the lookback period, the next DUI is a third-degree felony regardless of BAC. Even a general-impairment reading of 0.08% triggers felony grading at that point. The same automatic third-degree felony applies to anyone with a prior conviction for homicide by vehicle while DUI, no matter how many total DUI offenses they carry.¹

If that fourth-or-later offense also lands in the highest BAC tier, involves a controlled substance, or follows a test refusal, the charge escalates further to a second-degree felony. The difference matters at sentencing: a seven-year statutory maximum versus a ten-year maximum.¹

DUI With a Child Passenger and Two Prior Offenses

Driving under the influence with a passenger under 18 becomes a third-degree felony once the driver has two or more prior DUI convictions. The child does not need to be injured for the felony grading to apply.¹

DUI That Injures or Kills Someone

When a DUI causes serious harm to another person, the charge moves out of the standard grading tiers entirely and into separate, more severe felony offenses. These apply regardless of BAC level or prior-offense count.

Aggravated assault by vehicle while DUI is a second-degree felony. It applies when a driver violating the DUI law causes serious bodily injury: an injury that creates a substantial risk of death, causes serious permanent disfigurement, or produces long-term loss or impairment of any body part or organ. A broken bone that heals fully likely does not qualify; a traumatic brain injury or loss of a limb does. If the driver was unlicensed or driving on a suspended license at the time, the court can add up to two years of confinement on top of the standard sentence.²

Homicide by vehicle while DUI is the most severe DUI-related charge in Pennsylvania. With no prior DUI convictions, it is a second-degree felony. One prior DUI conviction lifts it to a first-degree felony with a 20-year statutory maximum. The mandatory minimum prison term runs three years with no priors, five years with one prior, and seven years with two or more priors, per victim. When multiple people die in the same crash, those sentences are typically served consecutively rather than concurrently.³

Prison Time and Fines by Felony Degree

Each felony DUI conviction carries a statutory range that combines the DUI-specific mandatory minimum with the general maximum for that felony degree.

Third-degree felony (third offense at the highest BAC tier, fourth offense at any level, DUI with a minor passenger and two priors): one to seven years in prison and a fine between $2,500 and $15,000.⁴⁵
Second-degree felony (fourth-or-later offense in the highest BAC tier, aggravated assault by vehicle while DUI, homicide by vehicle while DUI with no prior DUI convictions): one to ten years in prison and a fine up to $25,000.⁵⁶
First-degree felony (homicide by vehicle while DUI with one or more prior DUI convictions): three to twenty years in prison, with mandatory minimums climbing to five or seven years depending on prior convictions, and a fine up to $25,000.³⁶

Actual sentences fall inside those statutory ranges based on Pennsylvania’s sentencing guidelines, which give judges a recommended range built from offense gravity score and prior record. Court-ordered drug and alcohol treatment, court costs, and the other expenses below are on top of the fine.

License Suspension and Ignition Interlock

Every felony DUI conviction triggers an 18-month driver’s license suspension.⁷ Once driving privileges are restored, the driver must use an ignition interlock device for at least one year. The interlock requires a passing breath test before the vehicle will start and runs random retests while driving.⁸

Installation typically runs $100 to $200, and monthly lease and calibration fees fall in the $70 to $150 range. Tampering or violations can extend the requirement.

Firearm Rights Are Gone

Federal law prohibits anyone convicted of a crime punishable by more than one year in prison from possessing a firearm or ammunition. Every felony DUI in Pennsylvania carries a maximum sentence above one year, so the federal ban applies to all of them.⁹

DUI is not on Pennsylvania’s separate list of enumerated felonies that bar firearm possession under state law, but the federal prohibition alone is enough to strip gun rights permanently after a felony DUI conviction. There is no waiting period and no automatic restoration; the realistic paths back are a presidential pardon or expungement of the conviction.¹⁰

Consequences That Outlast the Sentence

The Record Stays

Felony DUI convictions in Pennsylvania are extremely difficult to remove. Misdemeanor DUIs may qualify for record sealing after seven years, but felony DUIs are not among the felony categories eligible for Pennsylvania’s limited-access sealing process. For most people, the only realistic path to clearing a felony DUI is a gubernatorial pardon, which is lengthy and uncertain.

Commercial Driver’s License

A first DUI conviction in any vehicle triggers a one-year CDL disqualification, or three years if the driver was transporting hazardous materials. A second DUI results in lifetime CDL disqualification.¹¹

Jobs and Professional Licenses

A felony conviction shows on background checks. Pennsylvania licensing boards for healthcare, education, law enforcement, and other regulated professions run those checks, and a felony DUI can disqualify applicants. Many private employers screen out felony convictions regardless of licensing.

Canadian Border

Canada is the most common travel problem for Pennsylvania residents with a DUI record. Canadian border officials classify foreign offenses by how the same conduct would be treated under Canadian law, and impaired driving is a serious criminal offense there. A driver can be turned away at the border whether the Pennsylvania offense was a felony or a misdemeanor. Two paths to overcome inadmissibility exist: a Temporary Resident Permit granted case by case, or criminal rehabilitation, which requires at least five years after all sentencing requirements are completed and takes a year or more to process.

The Broader Financial Hit

Court fines are a fraction of what a felony DUI actually costs. Legal defense typically runs $10,000 to $25,000 or more depending on whether the case goes to trial. Mandatory drug and alcohol treatment, ignition interlock installation and monitoring, license reinstatement fees, and years of higher auto insurance premiums pile on. Insurance rates after a DUI can double or triple. Added up, the total cost of a felony DUI conviction commonly exceeds $50,000 over several years.
