The impact of ignition interlock devices after a DUI conviction

On Behalf of | May 29, 2024 | DUI Defense

In Pennsylvania, a DUI conviction can lead to various penalties, one of which may be installation of an ignition interlock device (IID). If you are facing a DUI charge, how do you know if this is a penalty you face if convicted? Moreover, how can you navigate the consequences of a possible mandatory IID?

What is an IID?

An IID is a type of breathalyzer that connects to a vehicle’s ignition system. Before a driver starts the vehicle, they must blow into the device. If an IID detects alcohol, the vehicle will not start.

Who must use an IID?

According to Pennsylvania law, an IID is required for offenders who committed DUI for the first time with a blood alcohol content (BAC) of 0.10% or higher. An IID is also a requirement for those who committed second and subsequent DUI offenses as well as individuals who refused to undergo a chemical test.

Impacts of an IID

An IID can significantly affect various aspects of your daily life. Among its impacts are the following:

  • Driving limitations: An IID restricts your ability to operate any vehicle without an installed device. This means you cannot drive a friend’s car, a rental car or even a company vehicle without an IID. This restriction can impact your personal life, employment and overall mobility.
  • Financial burden: The installation, maintenance, and calibration costs of an IID are the driver’s responsibility. These costs can add up quickly, burdening you with an unexpected financial obligation.
  • Privacy concerns: An IID may require breath samples at random intervals while driving, a feature known as a rolling retest. This can cause inconvenience and embarrassment, especially if you have passengers.

Additionally, an IID records all test results. This can potentially raise privacy issues when authorities can regularly review your records.

Understanding your rights

Understanding the role of an IID in the DUI legal process is crucial for anyone facing a DUI charge. With legal support, you may dispute the arrest and challenge the charge. Furthermore, you can understand your rights and obligations regarding the possible installation and use of an IID.
