How this site is written
Every penalty, deadline, and eligibility rule on this site cites the controlling Pennsylvania statute — Title 75 (Vehicle Code) or Title 18 (Crimes Code) — so you can check it yourself. Pages are written or reviewed by Attorney Quinlan before publication, carry a last-reviewed date, and are corrected when the law changes (as with Act 58 of 2025 and 75 Pa.C.S. § 3802). Nothing here is legal advice for your specific case.

Don't make a statement to police beyond confirming your identity. Don't post about it on social media. Write down everything you remember about the stop while it's fresh. Then call a DUI defense attorney as soon as possible — Pennsylvania DUI cases move quickly and early decisions affect what's possible later.
Act 58 of 2025 created a new Pennsylvania DUI offense — 75 Pa.C.S. § 3802(h), 'DUI following diversion' — that lets the Commonwealth charge a new DUI committed within 10 years of completing ARD, and grade it at the second-offense level. It is not retroactive: it applies to DUIs committed on or after December 22, 2025. If you completed ARD any time after 2015 and pick up a new DUI, this likely affects you. See our Act 58 explainer for details.
