A previous blog post discussed the exemptions to Pennsylvania's Ignition Interlock Law. Those who can prove that installing ignition interlock devices in each of their motor vehicles would present an undue hardship may be allowed to install an ignition interlock system in only one vehicle, provided they do not drive any motor vehicle not equipped with an ignition interlock system.
Offenders who are required to drive in the course and scope of their employment may be allowed to drive vehicles owned by their employers -- without ignition interlock systems -- if the employer is properly notified of the employee's restriction. But, if an offender does not qualify for either of these exemptions, a violation of the Ignition Interlock Law can result in several penalties.
Those convicted of a second or subsequent DUI in Pennsylvania are required to comply with the Ignition Interlock Law. According to Pennsylvania statute, those subject to ignition interlock may not own, register, drive, operate or be in actual physical control of any motor vehicle that is not equipped with an ignition interlock system until they receive an unrestricted license.
Offenders will be issued an Ignition Interlock (II) license, which they must present to law enforcement when they are pulled over by police. If an individual with an ignition interlock license drives a vehicle without an ignition interlock device, they may be subject to penalties.
These penalties may include fines and jail time. If a non-compliant driver is pulled over in a vehicle without the ignition interlock device, they may be arrested and their car may be impounded. If it is the first offense of non-compliance, the required time for ignition interlock may be extended for an additional 12 months from the conviction date. Second and subsequent offenses may result in a 12-month driver's license suspension and a requirement that the offender comply with ignition interlock before his or her license is restored.
