What Happens If You Violate Your Interlock Device?

Posted by William Young | Sep 10, 2020 | 0 Comments

Today we have a guest article written by Lauren McDowell.

If you have been approved for a restricted driving program, an interlock installation will be required. If you are like most people, one of the pressing questions you'll probably ask is “What happens if I violate my interlock device?” The answer will often depend on two key components: where you live and the specific requirements that have been laid out in your restricted driving program.

If your ignition interlock device (IID) is court-mandated, you will most likely have additional rules to abide by. As a general rule of thumb, you need to have paperwork that will specify the restricted driving program rules you need to observe. Before you look into the possible consequences of violating your interlock device, it would be a good idea to first know what the main interlock device program violations are.  

What are Some of the Possible Interlock Device Program Violations?

Ignition interlock device program violations can be found in your IID handbook. They are also specified in your DMV or court paperwork. Washington DC and all 50 states have ignition interlock laws. Factors like who gets an IID installed and for how long can vary from one state to another. However, what constitutes a program violation is the same in every state.

Possible program violations include:

  • Inability to install the IID in the vehicle
  • Failing one (or more) startup tests
  • Skipping a rolling retest
  • Failing a rolling retest
  • Driving a vehicle without an IID
  • Tampering or removing the device
  • Having someone else take the breath test
  • Not paying the IID service provider
  • Skipping a service visit

Other possible violations are specific to the state or the program regulations. For instance, in some states, there will be restrictions regarding where you can drive and when. Not adhering to those parameters is considered a violation.

What are the Penalties for Interlock Device Violations?

Penalties for interlock device violations can vary from one state to another. While some states are lenient and will give you multiple chances, other states will impose penalties on your first violation. Some of the likely penalties include:

  • Revocation of the restricted license
  • Full suspension
  • Increase in the length of time required to have the device installed
  • Jail time
  • Fines
  • Revocation of parole (depending on the violation)
  • Losing driving privileges

Given that you strictly adhere to the rules, you should be able to complete your restricted driving program right on schedule and without needing to pay additional fines or legal fees. Also, consider it best to check with your DUI lawyer or probation officer if you have additional questions regarding other possible violations.

What are Key Things to Take into Account When Choosing an Interlock Provider?

When choosing an interlock provider, the following key factors should rank high in your list:


Find out how long the interlock provider has been in business. Google the company name of possible prospects and see what comes up. You can also check out news articles or reviews to get additional information and insights. The company website would also be a great resource to look into.

ISO 9001 Certified

When you pick an interlock provider that's ISO 9001 certified, you can rest assured the IIDs will meet (or even exceed) industry standards. If anything, it is crucial that you choose an interlock device you can depend on each and every time.

Round-the-clock Support

For utmost ease and convenience, ensure the interlock service provider you'll choose provides support 24/7. Understandably, the last thing you want is being stuck in the middle of the night with a malfunctioning device and no help available. While you can resolve most of the issues on your own, it's still ideal to have access to help when you need it.
