About this guide

A Pennsylvania DUI case can produce a criminal sentence, a PennDOT suspension, a separate chemical-test refusal suspension and an ignition-interlock requirement. Identify the exact offense and every notice before calculating when driving may resume. Eligibility to apply for limited driving is different from receiving the license.

Identify the offense and blood-alcohol category

Vehicle Code section 3802 separates general impairment, high-rate alcohol, highest-rate alcohol, controlled substances and special categories. The ordinary concentration bands are at least 0.08 percent but below 0.10 percent, at least 0.10 percent but below 0.16 percent, and 0.16 percent or more. Impairment can also be established under provisions that do not depend on those ordinary bands.

Minors, commercial vehicles and school vehicles have separate provisions. An under-21 threshold is 0.02 percent; commercial vehicles generally use 0.04 percent and school vehicles 0.02 percent. Start with the convicted subsection rather than treating every alcohol-related case as the same offense.

Distinguish court punishment from license suspension

The criminal penalties in section 3804 include probation or imprisonment, fines, alcohol highway safety school and treatment when required. Its licensing provisions separately direct PennDOT to act after receiving the qualifying conviction record. Completing a jail term does not by itself complete the license process.

The ordinary suspension is 12 months for an ungraded misdemeanor or second-degree misdemeanor and 18 months for a first-degree misdemeanor or specified felony. The no-suspension exception requires an ungraded general-impairment offense, the applicable general-impairment penalty provision and no prior offense. Accident circumstances, grading and previous history can change that outcome.

Use the actual grading and prior-history determination

Section 3803 determines offense grading, including repeat offenses and specified aggravating circumstances. Pennsylvania also has provisions addressing DUI after completed diversion. A statement that this is the driver's first conviction does not necessarily answer every question about prior history or the charged offense.

For practical planning, obtain the sentencing disposition and compare it with PennDOT's notice. List the offense date, statutory subsection, grading and suspension term. If they do not correspond, resolve the particular reporting or legal issue rather than substituting a generic online penalty chart for the actual case.

Chemical-test refusal can produce another suspension

Under section 1547, a qualifying refusal following a DUI arrest ordinarily carries a 12-month civil suspension. The period becomes 18 months for specified previous refusal suspensions or prior DUI sentencing. The refusal provision has its own warning and procedural requirements.

The civil action does not require the same outcome as a criminal DUI prosecution. A favorable disposition in the criminal case therefore does not automatically cancel the refusal notice. Record each effective date and each appeal deadline separately. Refusal restoration fees are also distinct from an ordinary restoration fee and from criminal fines.

ARD has its own licensing consequences

Accelerated Rehabilitative Disposition under section 3807 can include a license suspension even though it is a diversion program. The statute lists no suspension for the ordinary below-0.10-percent category, 30 days for the qualifying high-rate category, and 60 days for listed highest-rate, unknown-concentration, drug or accident circumstances. A minor faces 90 days.

Use all applicable circumstances, not BAC alone. For example, an accident involving property damage can matter under the ARD provision. Program admission, treatment, school and court supervision also have their own conditions. An ARD suspension does not erase an independent refusal suspension arising from the same incident.

Consider the current IILL route

PennDOT's Ignition Interlock Limited License information describes the IILL used during an eligible suspension or revocation. It permits only the driving authorized by that credential in appropriately equipped vehicles. The person remains under suspension or revocation except for that authorized operation.

An IILL is not automatically issued when an interlock is installed. PennDOT must determine eligibility, receive the required petition and documentation, and issue the license. Someone who has never been licensed is not eligible for this route. A CDL holder may qualify for noncommercial limited driving, but the IILL cannot authorize commercial-vehicle operation.

Back to the topics

Match eligibility to the type of sanction

The IILL eligibility charts distinguish conviction suspensions, refusal suspensions and revocations. Qualifying first high-rate or highest-rate DUI suspensions can permit application upon receipt of the notice. A first ordinary refusal suspension generally requires six months served; an 18-month refusal category generally requires nine months.

Other sanctions or pending matters can affect the result. The IILL law questions and answers confirm ARD eligibility and explain that court-reported prison release information is required. Completing court-ordered treatment is required for full restoration even when it is not a prerequisite to IILL issuance.

Submit the petition with the right documents

Use the current DL-9108 and DL-9108SC petition package. It requires certified mailing to PennDOT, identification of the vehicles, insurance evidence and the self-certification. The current instructions specifically say not to take the petition to a Driver License Center or Photo Center.

Follow the surrender or acknowledgment requirement and obtain the required installation documentation. Keep the complete package and certified-mail receipt. A missing vehicle insurance copy or required signature can prevent issuance even when the underlying offense is eligible. Use the address printed on the current petition rather than an unrelated PennDOT payment address.

Budget for separate fees and service costs

The December 2025 petition and PennDOT's July 2025 driver licensing fee chart list an $85 nonrefundable IILL petition fee. Some July 2025 interlock fact sheets still show $80; use the current petition and fee chart when preparing payment. Duplicate or renewal and applicable restoration charges are additional.

For a chemical-test refusal, the petition calls for one-half of the refusal restoration fee with the application, with the balance required for unrestricted restoration. Installation, leasing and maintenance are vendor charges. Obtain the actual service price rather than assuming the petition fee includes the device or monitoring.

Back to the topics

Complete the interlock period and compliance process

PennDOT's ignition-interlock fact sheet explains the restriction and restoration requirements. Keep required maintenance appointments and use only vehicles authorized by the applicable license and interlock rules. A calendar end date does not authorize removal before the required process is finished.

PennDOT must receive the vendor's Declaration of Compliance before unrestricted issuance. The current IILL instructions generally examine the preceding two consecutive months; the ARD IILL route uses a 30-day period. Qualifying IILL time can count toward a mandatory interlock period arising from the same incident.

Keep the 2026 program separate from future legislation

Act 36 of July 20, 2026 schedules major interlock changes, including repeal of section 1556 and a replacement licensing framework. Those principal provisions take effect 16 months after enactment. A consolidated statute page displaying the scheduled repeal does not mean the operating IILL process has already ended in 2026.

The act also introduced interim eligibility-verification duties and some immediately effective amendments. For a current application, use the current PennDOT petition and notice. For a later application, check the effective date and the procedure then in operation rather than assuming that every provision of the 2026 act began together.

Back to the topics

Confirm restoration before returning to ordinary driving

Obtain the restoration requirements letter to identify outstanding court reports, fees, interlock obligations and other actions. PennDOT's restoration services also provide the relevant status and payment routes. Complete every open requirement, including those unrelated to the DUI.

If challenging a suspension, use the judicial-review route and the deadline stated in the notice. A request for limited driving does not itself appeal the suspension. Keep proof of the issued credential and current status before arranging a trip that requires unrestricted privileges.

Back to the topics

Plan around several different eligibility dates

A DUI record can contain a suspension start date, an earliest IILL application date, a limited-license issue date and a later unrestricted-restoration date. Write down what each date means. Serving enough time to apply is not the same as receiving authorization, and the device's installation date does not by itself establish the beginning or completion of every licensing requirement.

If a refusal action accompanies a conviction suspension, include both notices in the review. Ask PennDOT to clarify an unexplained eligibility date using the particular notice and statutory section, rather than assuming that the shorter period controls. Before changing vehicles or arranging device removal, check the license and vendor documentation applicable to that action. This prevents a scheduling decision about the equipment from getting ahead of the agency's licensing decision.

Frequently Asked Questions

Does every first Pennsylvania DUI require a license suspension?
No. A narrow exception applies to a first ungraded general-impairment offense meeting the statutory conditions. Other offense categories, accident circumstances, grading and prior history can produce a suspension.

Can a refusal suspension survive dismissal of a DUI charge?
Yes. The civil refusal action and criminal prosecution address different requirements. A criminal disposition does not automatically remove PennDOT's refusal action.

Does ARD guarantee that I keep unrestricted driving privileges?
No. ARD has its own suspension rules, and a separate refusal suspension can remain. Eligible drivers may apply for an IILL through PennDOT's current process.

Is an installed ignition interlock enough to drive during suspension?
No. PennDOT must issue the appropriate limited license and its conditions must be satisfied. Installation alone is not a driving credential.

What is the current IILL petition fee?
The current DL-9108 petition and July 2025 fee chart list $85. Other license, restoration and vendor charges may also apply. Older fact sheets showing $80 should not be used to calculate the current petition payment.

Did the July 2026 law immediately abolish the IILL?
No. The principal replacement and repeal provisions have a 16-month delayed effective date. The current IILL process remains relevant to 2026 applications.
