For many, an ignition interlock device (IID) feels like a hurdle between their driveway and their destination. Still, attempting to bypass this technology is rarely the “quick fix” it appears to be. In the eyes of the law, tampering is viewed as a direct violation of a court order, often carrying penalties more severe than the original restriction.
What counts as tampering with IID?
In Pennsylvania, the legal definition of tampering covers any clear attempt to disable, disconnect or bypass the system. This often includes:
- Asking someone else to blow into the device
- Attempting to disconnect or remove the device
- Using compressed air or other substances to trick the sensor
- Skipping required breath tests while you are driving
- Failing to appear for mandatory service appointments
- Covering or blocking the camera (if equipped)
State laws also strictly prohibit driving any vehicle that does not have an approved IID. If you borrow someone else’s car to avoid the device, the police treat this as a serious violation.
What are the penalties for tampering with IID?
If the court finds you guilty of tampering with an IID, you may confront:
- A fine between $300 and $1,000
- A mandatory prison sentence of up to 90 days
- An additional 12-month extension of your IID requirement
- A permanent criminal record for a misdemeanor offense
These penalties apply even if you do not successfully start the car. The law focuses on the intent to bypass the system, not just the result. Prosecutors often use the device’s data logs as primary evidence to prove you tried to circumvent the law.
Will tampering with IID affect driving privileges?
The Pennsylvania Department of Transportation receives regular reports from the private companies that track your device data. Beyond fines and jail time, a tampering incident will ruin your path to a full driver’s license.
A single violation typically triggers an automatic 12-month extension of your interlock requirement. This means you must pay for the device and monthly monitoring fees for an entire extra year.
If you get multiple violations, the state may take away your restricted license entirely. This can force you to start the long process of license restoration from the very beginning.
How will tampering with IID impact DUI cases?
Tampering does not just add new charges; it also damages your reputation in your original DUI case. Judges typically see a tampering report as a sign that you refuse to take your recovery seriously.
This behavior can lead to harsher sentencing or a rejection of your application for Accelerated Rehabilitative Disposition (ARD). If you lose your ARD status because of a device violation, you must deal with the full weight of the original DUI penalties. A prosecutor might argue that your actions prove you remain a risk to public safety.
Can you fight tampering allegations?
You can challenge tampering accusations in court. Device glitches can produce false reports that monitoring companies sometimes see as intentional violations.
Technical errors do occur. You can request maintenance records, calibration data and an independent expert’s review of the device logs. In some cases, environmental factors or medical conditions produce readings that look suspicious, so gather any medical records or notes that could explain the results.
Remember, the prosecution must prove you intentionally tampered with the device. Carefully review the evidence to see if the state has sufficient proof. Acting early in the process often makes the difference between a dismissed violation and additional criminal penalties.
