What is the Ignition Interlock Law?
Pennsylvania enacted the Ignition Interlock Law in an effort to improve highway safety, reduce repeat driving under the influence offenses, and decrease highway crashes and fatalities. Under the law, an individual convicted of a second or subsequent offense of driving under the influence is required to have an ignition interlock system installed on EACH motor vehicle they own, operate, or lease for one year. Individuals are not eligible for ignition interlock until a suspension of at least one year has been served.
