Traffic citations from $550; DUI cases quoted after a free case review.

Which court and MDJ office should I check?

Common Pleas venue: Dauphin County Courthouse, 101 Market Street, Harrisburg. The local MDJ office depends on the case location; the county network covers Harrisburg, Hershey/Derry Township, Lower Paxton, Susquehanna Township and Middletown. Bring the citation or hearing notice so the assigned office can be confirmed rather than guessed.

How should I evaluate ARD in Dauphin County?

Confirm current county screening and application instructions for your individual case. 75 Pa.C.S. § 3807 governs DUI ARD; after successful completion and dismissal, Rule 320 directs arrest-record expungement, subject to objections. No county admission or result is guaranteed.

What should I bring to a free case review?

Bring the citation or complaint, court notices and PennDOT correspondence. The review can address the stop, testing, prior record, license concerns and representation fees.

Local DUI Defense

Why Dauphin County DUI cases are different.

Dauphin County is Pennsylvania's capital county — Harrisburg, Hershey, Hummelstown, Middletown, Steelton, Lower Paxton, Susquehanna Township, Derry Township, and the I-83/I-81/Route 322/Route 422 interchange generate one of the highest DUI volumes in the state. State Police Troop H is headquartered here.

Dauphin County combines aggressive city policing (Harrisburg Bureau, Capitol Police), large-township DUI units (Lower Paxton, Susquehanna, Swatara, Derry), and PA State Police Troop H. Sobriety checkpoints and saturation patrols are routine on I-83, I-81, and Route 322.

A local Pennsylvania DUI lawyer can review the stop, testing, license consequences, and county-specific ARD process before the preliminary hearing.

FAQ

Frequently asked questions.

Common questions about DUI charges in Dauphin County, PA — courts, ARD eligibility, license suspensions, and what to do after an arrest.

  • Dauphin County Court of Common Pleas — Dauphin County Courthouse, 101 Market Street, Harrisburg. Preliminary hearings happen at the MDJ covering your arrest location (Harrisburg, Hershey/Derry, Lower Paxton, Susquehanna Twp, Middletown, etc.), then the case moves to Market Street.

  • Dauphin County accepts most first-time DUI offenders into ARD, with standard statutory disqualifiers (child in vehicle, serious-injury accident, certain priors, prior ARD within 10 years under Act 58). We file the ARD application and shepherd it through intake.

  • First-offense penalties depend on your BAC. General Impairment (.08–.099) carries a mandatory minimum of 6 months' probation, a $300 fine, and no license suspension. High BAC (.10–.159) adds a 12-month suspension and 48 hours minimum jail. Highest BAC (.16+), refusals, and controlled-substance DUIs trigger 72 hours minimum jail, a 12-month suspension, and fines up to $5,000. Ignition interlock is required on most suspensions.

  • Many first-time offenders may apply for Pennsylvania's Accelerated Rehabilitative Disposition (ARD) program, but admission is at the District Attorney's discretion. ARD avoids a conviction, and the ARD license suspension under 75 Pa.C.S. § 3807(d) ranges from none to 90 days. You may be disqualified if a child was in the vehicle, there was a serious-injury accident, or you have certain priors. Act 58 of 2025 created a separate § 3802(h) DUI-following-diversion offense when a new DUI occurs within 10 years of qualifying diversion.

  • Pennsylvania's implied consent law triggers a 12-month PennDOT license suspension for refusing chemical testing (18 months with a prior refusal suspension or a prior DUI sentence) — separate from the criminal DUI and applied even if you're acquitted. The refusal and the underlying DUI are challenged separately and often have different defenses.

  • The review starts with your charge, county, citation or complaint, court notices and any PennDOT correspondence. You can discuss the stop, testing, prior record and licensing concerns, then discuss representation and the quoted fee. No outcome is guaranteed.

  • Traffic citations from $550; DUI cases quoted after a free case review.

  • No. Pennsylvania ARD is governed by 75 Pa.C.S. § 3807; admission and case-specific requirements must be reviewed. Successful completion and dismissal invoke Rule 320's arrest-record expungement process, subject to objections.
