PennDOT DL-9108 Form: Ignition Interlock Limited License

PennDOT DL-9108 Form: Ignition Interlock Limited License – If your Pennsylvania driving privileges have been suspended or revoked due to a DUI (driving under the influence) conviction, Accelerated Rehabilitative Disposition (ARD), or chemical test refusal, you may be eligible for an Ignition Interlock Limited License (IILL). This restricted license allows you to drive vehicles equipped with an approved ignition interlock device during all or part of your suspension period.

The official form required to petition for this license is PennDOT Form DL-9108 (Ignition Interlock Limited License Petition), which includes the companion DL-9108SC (Self-Certification of Vehicle(s) To Be Operated). This guide explains everything U.S. drivers in Pennsylvania need to know about the form, eligibility, application process, fees, and requirements based on official PennDOT sources.

What Is an Ignition Interlock Limited License (IILL)?

An Ignition Interlock Limited License is a special driver’s license created under Act 33 of 2016. It permits eligible individuals whose operating privilege is suspended or revoked for DUI-related offenses or chemical test refusal under 75 Pa.C.S. § 3802, former § 3731, or § 1547 to operate only motor vehicles equipped with a functioning, approved ignition interlock system.

The license features a red banner with the words “LIMITED LICENSE” and “IGNITION INTERLOCK” displayed in the map of Pennsylvania. It does not authorize driving commercial vehicles or school buses.

Any period spent holding a valid IILL counts toward the mandatory ignition interlock period required for full license restoration under 75 Pa.C.S. § 3805.

Who Is Eligible for the Ignition Interlock Limited License?

Eligibility is governed by 75 Pa.C.S. § 1556. You may petition for an IILL if your Pennsylvania driving privilege is suspended or revoked for:

  • Driving under the influence of alcohol or a controlled substance (75 Pa.C.S. § 3802 or former § 3731), including ARD dispositions
  • Refusal to submit to chemical testing (75 Pa.C.S. § 1547)
  • A substantially similar out-of-state violation that requires ignition interlock use

Certain violations can make you ineligible. Always review your official notice of suspension/revocation and the official Ignition Interlock Limited License Eligibility Charts on the PennDOT website. Pending citations or convictions not yet processed by PennDOT may also affect eligibility.

Submit the following by certified mail (required by law under 75 Pa.C.S. § 1556(b)(1)):

  • Completed DL-9108 petition
  • Completed DL-9108SC self-certification form
  • Proof of insurance (copies only) for every vehicle listed (insurance identification card, declaration page, binder, or other acceptable proof)

Where and How to Submit the Petition?

Mail the complete package by certified mail only to:

PA Department of Transportation
Bureau of Driver Licensing
Ignition Interlock Limited License Unit
P.O. Box 68273
Harrisburg, PA 17106-8273

Do not take the petition to a Driver License Center or Photo Center. PennDOT will process the petition within 20 days of receipt and notify you in writing of eligibility. Allow up to an additional 7 days for mail delivery of the decision letter.

Before the IILL can be issued, you must surrender your current driver’s license (or submit Form DL-16LC).

What Happens After Approval?

Once approved and the interlock device is properly installed and certified by an approved vendor, PennDOT will issue the Ignition Interlock Limited License. You may drive only vehicles equipped with a functioning approved ignition interlock system.

Violations such as driving a non-equipped vehicle, tampering with the device, or failing to maintain the device can result in immediate recall of the IILL, extended interlock periods, additional suspensions, fines, and possible imprisonment.

To later obtain an unrestricted driver’s license, you must complete the required interlock period and have your vendor submit a Declaration of Compliance confirming no incidents (generally in the prior two months, or 30 days for ARD-related IILL cases).
