If you are required to install an ignition interlock device (IID) in Pennsylvania, the process generally involves confirming that the requirement applies to you, following the Pennsylvania Department of Transportation (PennDOT) instructions, selecting a PennDOT-approved ignition interlock vendor, having the device installed, and completing any required compliance steps before you can legally drive with the device.
Although many people associate ignition interlock devices with restricted driving privileges, the device and the driver’s license are not the same thing. In this FAQ, our driving under the influence (DUI) lawyer explains how to obtain and install the ignition interlock system itself. Later, we’ll discuss how an ignition interlock license fits into the process and answer other common questions.
Step 1: Review Your PennDOT Restoration Requirements
If you are required to install an ignition interlock device (75 Pa. C.S.A. § 3805), PennDOT will notify you through its restoration process rather than expecting you to determine the requirement on your own.
Approximately 30 days before you become eligible to restore your driving privileges, PennDOT generally mails a Restoration Requirements Letter. This letter explains every requirement that must be satisfied before your operating privilege can be restored, including whether an ignition interlock device is required.
Carefully review the letter before taking any action. It identifies your restoration eligibility date, outlines any outstanding requirements, and explains whether you must participate in Pennsylvania’s ignition interlock program. Installing a device before understanding PennDOT’s requirements may create unnecessary delays if additional restoration conditions still need to be met.
Step 2: Schedule Installation With a PennDOT-Approved Ignition Interlock Vendor
After PennDOT notifies you that an ignition interlock device is required, you must have the device installed by a PennDOT-approved vendor. Pennsylvania does not allow drivers to use just any installer. To locate an approved provider, visit the Pennsylvania DUI Association’s Ignition Interlock Vendor List.
PADUI is a private, non-profit organization that contracts with PennDOT. You can search by ZIP code to find installation and service centers near you. If you do not have internet access, you can call PADUI at 1-800-627-2384 to obtain vendor information.
Once you’ve identified a nearby provider, contact the vendor to schedule your installation appointment. Before your appointment, ask:
- What documents you need to bring, such as your PennDOT restoration paperwork, vehicle registration, and identification.
- How long the installation will take.
- How often you’ll need to return for calibration and maintenance appointments.
- What to do if your vehicle requires repairs or you purchase another motor vehicle while the device is installed.
The vendor will install the certified ignition interlock device, explain how to operate it, schedule future service appointments, and submit any required certifications to PennDOT as part of the ignition interlock program.
Step 3: Have the Ignition Interlock Device Installed
At your appointment, the approved vendor installs the ignition interlock device in the vehicle you are authorized to operate. Before the vehicle will start, you must provide a breath sample. If the ignition interlock device detects a breath alcohol content (BrAC) of 0.025 or higher, the vehicle will not start. For drivers under 21 and school vehicle drivers, the threshold is 0.020 BrAC. The device also requires random “rolling retests” while the vehicle is in operation to help ensure the driver remains alcohol-free.
Depending on the approved provider’s procedures, you may receive documentation confirming the installation. Vendors participating in Pennsylvania’s ignition interlock program also report required installation information to PennDOT as part of the state’s compliance process.
Before leaving the appointment, make sure you understand:
- How to properly provide a breath sample.
- When rolling retests may occur while driving.
- How often the device must be calibrated.
- What to do if the device displays an error message.
- Who to contact if the device malfunctions.
Understanding these requirements can help you avoid unnecessary compliance issues.
Step 4: Comply With PennDOT’s Ignition Interlock Requirements
Installing the device is only the beginning of the ignition interlock program. Throughout the required period, you must continue to use the device properly and comply with Pennsylvania’s monitoring requirements.
This generally includes:
- Attending all scheduled calibration and maintenance appointments.
- Providing breath samples whenever the device requires them.
- Avoiding any attempt to tamper with, disable, or bypass the device.
- Following all instructions provided by the approved ignition interlock vendor.
Under Pennsylvania law, drivers must satisfy the applicable ignition interlock requirements, including the required compliance period, before the device can be removed and unrestricted driving privileges restored.
Do You Also Need an Ignition Interlock Limited License?
Although they are closely related, an ignition interlock device and an Ignition Interlock Limited License (IILL) are not the same thing.
The ignition interlock device is the equipment installed in your vehicle. The IILL is a restricted driver’s license that allows eligible individuals to operate only vehicles equipped with an approved ignition interlock device.
Eligible drivers seeking an IILL generally must submit Form DL-9108 (Ignition Interlock Limited License Petition) and the application fee to PennDOT. The application also includes Form DL-9108SC. This form identifies the vehicle or vehicles the driver will operate and the approved ignition interlock vendor’s certification that the required IID has been installed.
Because the device must already be installed before the vendor can complete the certification, obtaining the ignition interlock device and applying for the IILL are separate although related processes.
How Long Do You Keep the Ignition Interlock Device?
The required ignition interlock period depends on the circumstances of your case and Pennsylvania law. Many drivers are required to use the device for one year, although the applicable period may vary. PennDOT’s restoration requirements and the governing statutes determine how long the device must remain installed.
What Happens if You Violate the Ignition Interlock Requirements?
Failure to comply with Pennsylvania’s ignition interlock requirements may delay the restoration of unrestricted driving privileges.
Examples of violations include:
- Missing required calibration appointments.
- Tampering with or attempting to bypass the device.
- Failing to comply with required monitoring.
- Removing the device before completing the required period.
Depending on the circumstances, additional consequences may apply under Pennsylvania law.
How Is an Ignition Interlock Device Removed?
Once you have completed the required ignition interlock period and satisfied PennDOT’s compliance requirements, the device may be removed by an approved ignition interlock vendor.
Pennsylvania also requires a Declaration of Compliance before unrestricted driving privileges may be restored. The declaration confirms that you successfully completed the required ignition interlock period in accordance with 75 Pa.C.S. § 3805.
