Frequently asked questions vary from state to state. For answers to questions specific to your area, please select your state from the list found at the bottom of the page.

Q: How does an ignition interlock connect to my vehicle?

A: An ignition interlock consists of a handset to conduct breath alcohol tests with and relays messages to the driver and an Electronic Control Unit (ECU) that is connected to the power and control circuits of the vehicle.

Q: How does an ignition interlock work?

A: An ignition interlock device controls the normal operation of a vehicle through a connection with the vehicle starter. To start the engine, the driver must provide an acceptable breath sample with a Breath Alcohol Concentration (BrAC) below the preset limit.

Q: Will the installation of an ignition interlock damage my vehicle in any way?

A: At our Service Centers, we ensure that every installation goes smoothly and according to plan. Our trained technicians are certified and know exactly how to treat your vehicle. If, however, you experience difficulties with your ignition interlock, please contact us for assistance.

Q: How often do I have to provide a breath sample?

A: During normal operation, the device requests the driver to provide additional breath samples to maintain compliance with program requirements. The frequency of additional breath samples occur at random intervals to ensure that alcohol has not been consumed since starting the engine. Retest frequency may vary depending on the requirements of your local jurisdiction. Please contact us for more information.

Q: Will the ignition interlock stop my vehicle after a failed breath test?

A: Our ignition interlock devices will never cause the vehicle engine to stop. Additional breath samples are required at random intervals to ensure that the driver has not consumed alcohol since starting the vehicle engine. The handset beeps and displays Retest when applicable. The retest request timer will activate and give you sufficient time to stop in a safe location before providing a breath sample. We do not recommend performing a breath test while the vehicle is in motion.

Q: Can I remove the device myself while I am enrolled in an ignition interlock program?

A: Removing the device yourself while enrolled in an ignition interlock program will result in revocation of your driving privileges and may result in a program violation. Please contact your DUI attorney or local jurisdictional authorities for more information.

Q: Can an ignition interlock be installed on a motorcycle?

A: We also install ignition interlocks on motorcycles, but certain modifications may apply. Please contact your local Service Center for more information.

Q: What happens if I forget my routine service appointment?

A: The handset will display a reminder for your appointment. After 5 to 7 days of missing your appointment, the device will enter lock out and your vehicle would need to be towed to a local service center.

Q: Can I reschedule my service appointments?

A: Yes, you can reschedule a service appointment if you cannot attend. Please contact your Service Center to reschedule.

Q: Can I install an ignition interlock at one location and be monitored at another location?

A: Yes, we have that option available. If you would like to be monitored in a different location, additional region specific jurisdiction regulations may apply. Please contact your Service Center for more information.

Q: How long will the interlock condition be on my license?

A: The length of an ignition interlock program depends on multiple factors, such as the state where the DUI was committed, BAC level at the time of DUI offense, number of previous DUI violations and etc. Please contact your DUI attorney or local jurisdictional authorities for more information.
