Ignition Interlock Devices After a DUI: What Drivers Should Expect

For drivers who are charged with DUI, one of the most disruptive aspects is having an ignition interlock device (IID) installed in their vehicle. These are becoming more and more common in DUI cases, including for first-time offenders. Learning about the requirements for IIDs can prevent drivers from making costly mistakes.
What is an ignition interlock device?
Ignition interlock devices are basically breathalyzers installed in your vehicle, which prevent the engine from being started if there is alcohol in the driver’s breath. Before the engine can be started, the driver must blow into the IID.
Some IIDs require the driver to take a “rolling retest” while the vehicle is running to ensure that the driver has no alcohol in his or her system.
If alcohol is detected by the IID, the vehicle will not be able to start or a violation will be registered with the monitoring company.
When are IIDs required?
While the specific requirements for IIDs differ among states, it has become much more common to require IIDs for the following situations:
- For first-time DUI offenders
- For those who refused the breath or blood test
- For those with high BACs
- For those with prior DUI offenses
Some states require drivers to install an IID as a condition of receiving a limited or “hardship” driving privilege before their case has even been resolved.
Common myths about IIDs
There are several misconceptions when it comes to IIDs. One misconception is that the IID is only necessary when you’ve been drinking. However, some foods, mouthwashes, and car problems might cause false positives and prevent you from starting your car.
Another misconception is that failing to pass a test with the IID is not a big problem. The device reports any violations, and you could be charged with another DUI, have your hardship license revoked, or spend more time with the IID installed on your vehicle.
Costs and practical challenges
IIDs can be quite expensive. The offender will bear the cost of the interlock, the monthly monitoring, the calibrations, and the removal of the device.
The devices can also affect the offender’s work, family, and commuting, especially if the offender depends on the vehicle for daily activities.
Legal issues and defense considerations
It’s worth noting that requirements for an IID are not always mandatory or inevitable. There are some cases where a person can dispute the requirements, especially if there have been some issues with the initial arrest.
An experienced DUI attorney can help determine if a requirement for an IID is appropriate, as well as ways to reduce the effects on your life.
Why compliance matters
Consequences for failing to comply with IID laws can include an extended period with the IID, additional fines, and further suspension of your license.
If you are facing a DUI charge, it can be very beneficial to speak with a lawyer to understand the IID requirements and prevent potential complications.
