The Pennsylvania Ignition Interlock Limited License (IILL) is for people with suspended or revoked driving privileges. This usually happens due to DUI violations or refusing a chemical test.

The purpose of the IILL is to allow individuals to drive legally if they have an ignition interlock system installed in their vehicle.

To qualify for the IILL, individuals must meet specific eligibility requirements. First-time and repeat DUI offenders must apply. They must have a valid driver’s license before the suspension.

Individuals must also agree to have a working ignition interlock device in their vehicle. This system requires the driver to pass a breath test to start the car. A hardship exemption may apply for those who face special circumstances.

Key aspects and conditions of the license

Both first-time and repeat offenders must have this license. Drivers must keep the ignition interlock system working properly during the entire IILL period.

Individuals need to hold the IILL for one year. Only then can the Pennsylvania Department of Transportation (PennDOT) issue a full, unrestricted driver’s license again. Some hardship exemptions exist for those who need the license for work or other essential activities.
