DUI in Pennsylvania: the law, the limits and the device
Verified · next review
Pennsylvania calls it DUI — driving under the influence, and you will see drunk driving used for the same offense. What follows is what this state sets, taken from its own published rules rather than from a national summary.
What Pennsylvania law actually requires
Pennsylvania created the Ignition Interlock Limited License in 2016 — it lets you drive an interlock-equipped car through part of your suspension instead of waiting it out. A plain first general-impairment offense carries no interlock requirement at all; the mandate starts at high BAC, on a refusal, or on a repeat.
- First offense: None for a first general-impairment offense; required at high BAC, on a refusal, or on a repeat, with the Ignition Interlock Limited License as the route back to driving
- Lockout threshold: Set by the approved system; your vendor must file a Declaration of Compliance showing two incident-free months before the restriction comes off
- Program run by: PennDOT, Bureau of Driver Licensing

DUI vs DUI in Pennsylvania
In Pennsylvania there is one offense and one label. If you have seen DWI, OWI or OVI used elsewhere, that is another state’s vocabulary for the same conduct — nothing about the seriousness changes when you cross a state line, only the letters on the paperwork.
Whatever it is called, the licensing consequence is the same shape: a suspension, then the device as the condition of driving again. All six abbreviations, side by side →
Can you get a DUI on a bike or a horse in Pennsylvania?
It turns on one word in the statute. Where the law says “vehicle”, no engine is required and the charge can reach a bicycle, a horse or a mobility scooter. Where it says “motor vehicle”, the analysis is different. This is decided by your state’s own wording, not by national custom, and it is the first thing to check before assuming a bike ride home is safe.
Where this state departs from the national picture
Most of what people read about drunk driving is written for the country as a whole. These are the points where Pennsylvania does something of its own.
Third offense, or a second with a high reading
Pennsylvania grades by prior count and by what the reading was. Three or more prior offenses make it a third-degree felony; so does a second prior when the current offense involves the highest tier or a refusal. A minor under 18 in the car pushes a first offense to a first-degree misdemeanor and a repeat to a felony. This is the change people remember: Act 153 of 2018 created felony grading where none existed before.
No SR-22 — ordinary proof of insurance for Not applicable
Pennsylvania is one of the states that never adopted the certificate. Its restoration requirements letter — the document that lists everything you must do to get the licence back — asks for proof of insurance in the ordinary sense, and PennDOT’s own list of acceptable proofs is an insurance identification card, the declaration page, an assigned-risk application, a self-insurance certificate, a binder, or a letter from the carrier’s head office. No form is filed with the state on your behalf, and nobody monitors it for three years.

How often this happens in Pennsylvania
Federal crash records show the scale the state is legislating against, and how it compares with the country.
Cases are heard where the stop happened, and volume shapes local practice. These PA counties record the most:
Source: NHTSA Fatality Analysis Reporting System, 2020–2022. Counts crashes where police recorded that a driver had been drinking, which is narrower than the federal 0.08 measure and therefore understates the real figure. Pennsylvania runs at or below the national share.
What it costs to get driving again in Pennsylvania
Pennsylvania does not publish a price cap we could verify, so the quote is the number and your only leverage is a competitor nearby. The national reference points are installation and a monthly fee, with calibration visits every 30 to 60 days.

The two clocks in Pennsylvania
The court case and the licensing case run separately. The licensing side moves first, and in the strictest states the window to request a hearing is measured in days — it runs whether or not you have hired anyone.

The county that hears your case is set by where the stop happened, and local practice differs across the state.
DUI questions in Pennsylvania
Is it called DUI or DUI in Pennsylvania?
Pennsylvania uses DUI — driving under the influence. You will also see drunk driving used for the same thing. The label follows the state, not the seriousness of what happened, so paperwork from elsewhere may say something different about identical conduct.
What is the legal limit in Pennsylvania?
0.08% for drivers 21 and over, as in every state except Utah, which sits at 0.05%. Below the limit you can still be charged if an officer documents impairment. The reading that triggers the interlock here is a separate number: Set by the approved system; your vendor must file a Declaration of Compliance showing two incident-free months before the restriction comes off
When does a DUI become a felony in Pennsylvania?
Third offense, or a second with a high reading. Pennsylvania grades by prior count and by what the reading was. Three or more prior offenses make it a third-degree felony; so does a second prior when the current offense involves the highest tier or a refusal. A minor under 18 in the car pushes a first offense to a first-degree misdemeanor and a repeat to a felony. This is the change people remember: Act 153 of 2018 created felony grading where none existed before.
How long does the interlock stay on after a first offense in Pennsylvania?
None for a first general-impairment offense; required at high BAC, on a refusal, or on a repeat, with the Ignition Interlock Limited License as the route back to driving The program is run by PennDOT, Bureau of Driver Licensing.
Can you get a DUI on a horse or a bicycle in Pennsylvania?
The answer is in whether the statute says “vehicle” or “motor vehicle”. Where it says vehicle, no engine is needed and the charge can reach a bike or a horse; where it says motor vehicle, it cannot. This is one of the most searched questions in the whole subject and one of the most confidently answered wrongly — the wording of your own state decides it.
What happens on a third DUI in Pennsylvania?
Pennsylvania grades by prior count and by what the reading was. Three or more prior offenses make it a third-degree felony; so does a second prior when the current offense involves the highest tier or a refusal. A minor under 18 in the car pushes a first offense to a first-degree misdemeanor and a repeat to a felony. This is the change people remember: Act 153 of 2018 created felony grading where none existed before. Beyond the class of the offense, a repeat also lengthens the interlock requirement and the insurance filing that follows it.
