Pennsylvania Ignition Interlock Laws

 When is an Interlock Device Required in PA?

Under Pennsylvania DUI laws, if you are convicted of a second offense DUI charge, you will be required to install an ignition interlock device in any vehicle you drive, when you are eligible to have your driver’s license reinstated.

Note that these laws are subject to change. There is an aggressive effort by lawmakers in Pennsylvania to follow suit with other states that require an ignition interlock after any DUI, even a first offense. 

What is an Ignition Interlock Device?

An IID is an electronic instrument that connects to your car’s ignition as a “rolling breathalyzer”. You must blow into the device to establish that you have not been drinking, or your car will not be allowed to start, and a failure will be logged in the system. It detects the equivalent of a .025% BAC, or about one drink for an average sized person. (the legal limit is .08%).

When Do I have to Get One?

If you have a 2nd offense Pennsylvania DUI, after being convicted you will first have to serve a full 1 year license suspension with no ability to drive.

When your suspension period is up, you will be eligible for a limited license which requires use of the ignition interlock to legally drive, for the following 1 year.

How Do I Get The Device?

When your license suspension period is up, you should be notified by mail, or contact PennDot to confirm your eligibility and get the necessary paperwork to process your ignition interlock (II) license.
