Pennsylvania DUI law has undergone a significant change regarding whether Accelerated Rehabilitative Disposition (ARD) counts as a prior offense. The issue is not just statutory—it is constitutional. The Pennsylvania Supreme Court addressed this directly in Commonwealth v. Shifflet, and the legislature has now attempted to respond.

The result is a more complicated legal landscape that every DUI defendant—and every attorney handling DUI cases—needs to understand.

What Is ARD and How Was It Previously Treated?

ARD is a pretrial diversion program that allows a defendant to avoid a conviction by completing supervision, treatment, and other conditions. Upon successful completion, the charges are dismissed.

For many years, however, Pennsylvania law treated ARD as a “prior offense” for purposes of enhancing penalties in subsequent DUI cases. That meant a person who never pled guilty and was never convicted could still face mandatory jail and increased penalties on a later DUI.

The Constitutional Problem Identified in Commonwealth v. Shifflet

In Commonwealth v. Shifflet, the Pennsylvania Supreme Court held that treating ARD as a prior offense violated constitutional protections.

The Court's reasoning was straightforward. ARD is not a conviction. It does not require a jury finding of guilt. It does not require an admission of guilt under oath. Yet it was being used to increase mandatory minimum penalties in future cases.

Under the Sixth Amendment and due process principles, a defendant cannot be subjected to enhanced punishment based on facts that were never proven to a jury or admitted in a constitutionally valid manner. Because ARD lacked those safeguards, it could not be used as a prior offense.

The Legislature's Response: The 2025 DUI Law

In response to Shifflet, the Pennsylvania legislature amended the DUI statute, effective December 2025.

Under the new law, ARD may count as a prior offense, but only if it is entered under specific conditions. The defendant must enter ARD on the record, under oath, with an acknowledgment of the consequences. In other words, the legislature attempted to convert ARD into something that resembles a constitutionally valid admission.

Does the New Law Cure the Constitutional Problem?

The answer is that it likely addresses part of the problem, but it does not eliminate all constitutional concerns.

For ARD cases entered after the effective date of the new law, the Commonwealth now has a stronger argument. If the defendant is placed under oath and knowingly acknowledges that ARD may be used as a prior offense, courts may view that as a valid admission sufficient to support enhanced sentencing in the future.

However, the new law does not fix the issue for older ARD dispositions. Any ARD entered before the statutory change was not made under oath and did not include the required acknowledgment. Under Shifflet, those ARDs cannot constitutionally be used to enhance a later sentence.

Attempts to apply the new law retroactively raise serious constitutional concerns, including ex post facto violations and due process issues. Courts are likely to reject efforts to use pre-2025 ARDs as prior offenses under the revised statute.

Even for ARDs entered under the new law, challenges will remain. The validity of the admission will depend on whether the defendant was properly sworn, whether the colloquy was adequate, and whether the record clearly establishes a knowing and voluntary acknowledgment. If those elements are lacking, the use of ARD as a prior offense may still be subject to challenge.

Practical Impact for DUI Cases

For individuals with a prior ARD, the timing of that ARD is critical. If it occurred before December 2025, there is a strong argument that it cannot be used as a prior offense. If it occurred after the new law took effect, it may count, but only if the statutory requirements were strictly followed.

For individuals considering ARD now, it is important to understand that ARD is no longer without future consequences. A properly entered ARD may later be used to increase penalties, including mandatory jail, if another DUI occurs. HOWEVER, MANY COUNTIES ARE NOT CREATING THE RECORD TO ENSURE THE APPLICABILITY OF THE SHIFFLETT CURE. Only knowledgeable counsel will know to challenge the prior ARD granted after December of 2025.

Defense Considerations

The changes to the law have created multiple avenues for defense. These include challenges to the use of pre-2025 ARDs, challenges to defective ARD colloquies, and constitutional arguments based on due process and improper retroactive application.

Each case must be analyzed carefully. The mere existence of a prior ARD does not automatically mean it qualifies as a prior offense under the law.

Conclusion

The law in Pennsylvania now distinguishes sharply between ARDs entered before and after the 2025 statutory change. Older ARDs remain subject to the constitutional protections recognized in Shifflet and generally cannot be used to enhance sentencing. New ARDs may qualify as prior offenses, but only if they meet strict constitutional and statutory requirements.

The legislature has attempted to address the constitutional problem identified by the Court, but the issue is not fully resolved. Litigation in this area is ongoing, and the outcome in any given case will depend on the specific facts and the quality of the record.

If you are facing a DUI charge and have a prior ARD, it is essential to have the issue analyzed by experienced counsel. The difference between a first offense and a second offense can mean the difference between no jail and mandatory incarceration.
