What Happens After a DUI Arrest in Pennsylvania? (Step-by-Step Guide)
Pennsylvania DUI attorney Sean Quinlan walks through what actually happens after a DUI arrest in PA — from the two-track criminal and PennDOT license system, to the first 48 hours, the ARD program, court phases, license protection, weak points in the Commonwealth's case, and what "case over" really means for CDL holders and licensed professionals.
Why this matters for your Pennsylvania DUI case
Most people arrested for DUI in Pennsylvania don't realize the criminal case and the license case are two separate proceedings until one of them causes a problem they didn't see coming. Missing a PennDOT deadline can lock in a suspension even if the criminal case is later reduced or dismissed. Understanding the process step by step — from the traffic stop through ARD, plea, or trial — lets you make better decisions early, when the case is still most defensible.
- A Pennsylvania DUI runs on two tracks from day one — the criminal case in court and the PennDOT license case — each with its own deadlines and appeals.
- The first 48 hours matter: write down what happened, preserve evidence, and identify chemical-test or stop issues before details fade.
- PA DUI tiers are driven by BAC (General Impairment, High BAC, Highest BAC) and by whether drugs, refusal, or a prior offense are involved — the tier controls mandatory minimums.
- The court phases — preliminary hearing, formal arraignment, pretrial conference, motions, and trial or plea — each open a specific window for defense strategy.
- License protection often has to start before the criminal case is even resolved; missing a suspension or hearing request can be irreversible.
- ARD is a first-offender diversionary program that can lead to dismissal and expungement, but eligibility rules are strict and easy to lose.
- DUI cases most often get weaker at the stop, the field sobriety tests, and the blood-test chain of custody or lab procedures.
- Outcomes range from dismissal or reduction, to ARD, to a negotiated plea, to trial — the right path depends on the evidence, the tier, and priors.
- 'Case over' does not mean 'consequences over' — license, ignition interlock, insurance, and record-based collateral consequences can continue.
- CDL holders and licensed professionals face additional employer and licensing-board exposure that a general plea deal will not address.
