Ignition Interlock

An Ignition interlock is a device that is installed into motor vehicles to prohibit individuals under the influence of alcohol from operating the vehicle. Individuals are required to blow into the device before starting the vehicle. If the device detects alcohol, it will prevent the vehicle from starting. In addition, at random times during the operation of the vehicle, the driver will be prompted to blow into the device to ensure they are not under the influence.

What is the Pennsylvania Ignition Interlock Program?

Act 33 was signed into law on May 20, 2016 with a start date of August 25, 2017. The main feature of the new law was requiring Ignition Interlocks for the first time DUI offenders (convictions only) with a BAC of .10% or greater. The law also mandates ignition interlock for individuals who have violated Section 1547 (relating to chemical testing to determine the amount of alcohol or controlled substance). The prior law required interlock to be installed on all owned vehicles. This no longer applies and only requires it to be installed on any vehicle(s) being driven by the individual. Act 33 of 2016 also established an Ignition Interlock Limited License. An Ignition Interlock Limited License is a driver’s license issued to an individual whose operating privilege is suspendered or revoked for one or more violations of driving under the influence of alcohol or a controlled substance or refusal to submit to chemical testing. An Ignition Interlock Limited License permits an individual, if certain requirements are met, to operate a motor vehicle(s) equipped with an interlock system during the term, or part of the term, of their suspension or revocation. In January of 2002 PENNDOT awarded a contract to the Pennsylvania Driving Under the Influence Association (PA DUI) for the Pennsylvania Ignition Interlock Quality Assurance Program. The program oversees the quality assurance aspect of the ignition interlocks approved and used in Pennsylvania, provides technical assistance to manufacturers, service providers and ignition interlock users; and ensures that ignition interlock manufacturers and service providers adhere to the PENNDOT specifications.
