Pennsylvania Ignition Interlock Device Guidelines

In 2017, Pennsylvania enacted a new law (ACT 33 of 2016) to require the installation of Ignition Interlock system for most 1^st offense and all subsequent DUI (driving under the influence) offenses. The individual convicted of a DUI offense who is required to install an Ignition Interlock Device must do so for a period of 1 year.  After that period has passed, you may be eligible for an unrestricted driver’s license.

There are two types of Ignition Interlock Licenses available in Pennsylvania (Ignition Interlock Limited License) IILL or the (Ignition Interlock Restricted License) IIRL.

The Ignition Interlock Limited License allows an individual to drive during their suspension term.  In order to be eligible to receive an IILL, the individual must own or have a vehicle available to them to install an Ignition Interlock Device.  You must then petition PennDOT for this license via PennDOT form DL-9108SC.

For more information on IILL please refer to PennDOT’s IILL Fact Sheet.

The Ignition Interlock Restricted License is required for all individuals who have served their period of license suspension resulting from a DUI conviction.  The IIRL must be obtained through PennDOT and held for a period of one year.  Only after holding this license for a period of one year, the individual will receive their unrestricted driver’s license back.  The individual must obtain their IIRL even if they do not own or have available to them a vehicle for an IID to be installed in.

General Information

.08 DUI Legislation

Act 24, which lowered Pennsylvania’s legal limit of alcohol from .10 to .08, was signed into law on September 30, 2003. The new Driving Under the Influence (DUI) Law creates a tiered approach toward DUI enforcement and treatment, and includes many changes to the penalties, terms of suspension, fines and other requirements. The combination of an individual’s Blood Alcohol Content (BAC) level, and prior offenses, determines the licensing requirements and penalties. The new law focuses on treatment for first-time DUI offenders, rather than strictly punishment and suspension.

There are now three levels of DUI:

1. General Impairment (.08 to .099% BAC)
2. High BAC (.10 to .159% BAC)
3. Highest BAC (.16% and higher)

Under the new DUI law minors, commercial drivers, school vehicle or bus drivers, and offenders involved in an accident that injures someone or causes property damage may be subject to the high BAC penalties even if their BAC is not in the high category. Offenders who refuse breath or chemical testing may be subject to the highest BAC penalties. The following charts show the penalties for each of the BAC categories:

General Impairment penalties (Undetermined BAC, .08 to .099% BAC)

The new law creates a higher set of penalties for those having higher BAC levels. It allows for treament at all levels, and requires alcohol highway safety school for all first and second time offenders.

High BAC penalties (.10 to .159% BAC)

The following outlines specific components of the new law, and changes from the previous law that impacts DUI drivers.

• Ignition Interlock Violations:Individuals convicted of driving without or tampering with the ignition interlock device will have their ignition interlock period extended 12 month from the date of conviction for the first offense and will have their driving privileges suspended for 12 months for the second or subsequent offenses. Upon restoration they must comply with ignition interlock for 12 months. Individuals, whose driving privileges are suspended during the ignition interlock period for a non-ignition interlock violation, must complete the ignition interlock period upon restoration.

-Effective February 1, 2004

* “Per se” is a Latin phrase that means “by itself.” Evidence that a person drove, operated or was in control of a motor vehicle with a BAC of .08% or higher is enough by itself to convict the person of DUI. A person with BAC less than .08% might still be convicted of DUI is there is evidence that he or she imbibed enough alcohol to make him or her incapable of safely driving, operating or being in control of a motor vehicle.
