Pennsylvania DUI Laws Changed in 2026: What Drivers Need to Know About Act 58

Pennsylvania drivers entering 2026 are dealing with an important change in DUI law. Act 58 of 2025, signed on December 22, 2025, took effect immediately and changed how prior participation in Accelerated Rehabilitative Disposition, or ARD, can affect a later DUI case.

The law was enacted after the Pennsylvania Supreme Court’s decision in Commonwealth v. Shifflett. That case held that simply accepting ARD could not be treated the same as a prior conviction for enhanced DUI sentencing under the law as it then existed. Act 58 created a new statutory framework intended to preserve ARD while allowing greater consequences for certain later DUI offenses.

Act 58 at a Glance

Change	What Pennsylvania Drivers Should Know
New DUI-after-diversion provision	A DUI committed within 10 years after completing qualifying ARD can carry enhanced consequences
ARD waiver process	Defendants entering ARD must knowingly and voluntarily waive applicable constitutional rights on the record
PennDOT record retention	ARD acceptance and completion records are generally retained for 12 years instead of 10
Future DUI penalties	Certain later offenses after ARD can be punished at levels similar to subsequent DUI offenses

These changes make the long-term consequences of entering ARD more important to understand before accepting the program.

A New Rule Applies After Completing ARD

Act 58 added Section 3802(h), covering DUI offenses committed after diversion.

Under the new provision, a person may not commit another DUI within 10 years after completing ARD or a substantially similar pretrial diversion program for a prior DUI offense. The law also explains how prosecutors may prove that earlier ARD completion, including through PennDOT or court records.

That distinction matters. The law focuses on completion of ARD followed by a new DUI within the 10-year period, rather than simply labeling ARD itself a criminal conviction.

Someone with a past ARD who is arrested again should tell a dui attorney about the earlier case immediately because the dates and disposition can affect how the new charge is handled.

Penalties Can Be More Serious After Diversion

Act 58 also amended Pennsylvania’s DUI penalty provisions.

For example, under the general-impairment tier, a first violation of the new DUI-after-diversion provision can carry penalties associated with a second offense, including:

• At least five days of imprisonment
• A fine ranging from $300 to $2,500
• Alcohol Highway Safety School
• Required drug and alcohol treatment when applicable

Different penalty levels apply to higher-BAC, controlled-substance, and other DUI categories, so the actual exposure depends on the facts and grading of the current charge.

A dui defense attorney can review the current DUI tier, prior ARD history, and whether the new Section 3802(h) provision applies.

ARD Records Are Now Kept Longer

Another practical change is record retention.

Act 58 changed PennDOT’s general retention period for records showing acceptance and completion of DUI-related ARD from 10 years to 12 years. After that period, PennDOT generally must expunge the record unless a statutory exception applies, including certain habitual-offender or commercial-driver situations.

This 12-year retention rule should not be confused with the 10-year period used by the new DUI-after-diversion offense. They serve different legal purposes.

ARD Now Includes an On-the-Record Waiver

Act 58 also requires additional safeguards when a defendant enters ARD.

The court must conduct an on-the-record inquiry to determine that the defendant knowingly, voluntarily, and intelligently accepts the program and waives applicable constitutional rights. This change directly addresses concerns raised by the Shifflett decision about using ARD later when the original process lacked protections associated with a conviction or guilty plea.

What Should Drivers Do After a DUI Arrest?

Do not assume that a charge will be treated as a first offense simply because an earlier DUI ended through ARD.

Gather information about:

• The date of the previous DUI
• When ARD was completed
• Whether the prior case occurred in Pennsylvania or another state
• The BAC or drug allegations in the current case
• Any license suspension or ignition-interlock history

A dui defense lawyer can determine how Act 58 applies to those facts and whether ARD, sentencing enhancements, license consequences, or other defenses need to be addressed.

Act 58 did more than make a technical change to Pennsylvania DUI law. It reshaped the relationship between ARD and future DUI charges, which makes understanding the consequences of both the current case and any prior diversion history especially important in 2026. PA4Law follows these changes closely and helps drivers understand how Act 58 may affect their options, risks, and next steps after a DUI arrest.
