Ignition Interlock

Ignition Interlock is a device that is installed on motor vehicles to prohibit individuals from driving under the influence of alcohol. Pennsylvania law requires individuals convicted of a second or subsequent offense of driving under the influence to have an Ignition Interlock device installed on all motor vehicles they own, operate or lease. If you are required to obtain an Ignition Interlock device, your suspension notice will advise you. In addition, a Restoration Requirements letter will be mailed to you 30 days before you are eligible to be restored listing the Ignition Interlock requirement. To learn more detailed information regarding Ignition Interlock, read the Ignition Interlock Fact Sheet.
