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.
