Every Pennsylvania DUI is different. The BAC tier, prior offenses, accident, refusal, and stop legality all change the strategy. We investigate every piece — from the initial traffic stop to the calibration of the breath machine.

FAQ

Frequently asked questions.

Common questions about Pennsylvania DUI charges, ARD, license suspensions, and what to do after an arrest.

  • Pennsylvania's first-offense DUI penalties depend on your BAC tier. General impairment (BAC .08–.099) typically carries up to 6 months probation, a $300 fine, and no license suspension if there are no aggravating factors. High BAC (.10–.159) adds a 12-month license suspension and 48 hours minimum jail. Highest BAC (.16+), refusals, or controlled-substance DUIs carry 72 hours minimum jail, a 12-month suspension, and fines up to $5,000. Ignition interlock is required on most first offenses with suspension.

  • Most first-time DUI offenders are eligible for Pennsylvania's Accelerated Rehabilitative Disposition (ARD) program. ARD avoids a conviction, allows expungement after completion, and typically involves a shorter license suspension and supervised probation. You may be disqualified if a child was in the vehicle, there was an accident with serious injury, or you have certain prior offenses. Note: under Act 58 of 2025, a new DUI committed within 10 years of completing ARD can be charged under the new 75 Pa.C.S. § 3802(h) 'DUI following diversion' offense — graded at the second-offense level.

  • Pleading guilty without an attorney usually means accepting the worst-case version of every penalty — full license suspension, maximum fines, and a permanent criminal record. A defense attorney reviews the legality of the traffic stop, breath or blood test calibration, chain of custody, and your eligibility for ARD or reduced charges. In many cases the charge is reduced or dismissed entirely on issues the prosecutor wouldn't volunteer.

  • It depends on the tier and whether it's a first or subsequent offense. General-impairment first offenses carry no suspension. High BAC and Highest BAC first offenses carry a 12-month suspension. Second offenses carry 12–18 months. Refusal of a chemical test triggers a separate 12-month PennDOT suspension that applies even if you're acquitted of the DUI. You may also need an ignition interlock device for one year after reinstatement.

  • Under Pennsylvania's implied consent law, refusing chemical testing triggers an automatic 12-month license suspension through PennDOT — separate from any criminal DUI penalty, and applied even if you are never convicted. You may still face DUI charges based on officer observations. Both the refusal suspension and the underlying DUI can be challenged separately, often with different defenses.

  • Most Central PA DUI attorneys charge a flat fee that varies by case complexity — typically a few thousand dollars for a standard first-offense case and more for cases involving accidents, refusals, suppression hearings, or trial. We offer free consultations and discuss fees up front; for many clients the cost is offset by avoiding a suspension, jail time, or a permanent criminal record.

  • Act 58 of 2025 created a new Pennsylvania DUI offense — 75 Pa.C.S. § 3802(h), 'DUI following diversion' — that applies when a new DUI is committed within 10 years of completing ARD. A first § 3802(h)(1) conviction is graded and penalized under the same statutory provisions as a second-offense DUI: mandatory jail, longer license suspension, and no second bite at ARD. Act 58 is not retroactive; it applies to DUIs committed on or after December 22, 2025. See our Act 58 explainer for the full breakdown.
