All 50 states have laws on the books regarding the use of Ignition Interlock Devices. Studies have shown that Ignition Interlock Devices make the roads safer by preventing a vehicle from starting if there is an unlawful amount of alcohol on a driver’s breath.

There are a number of factors that go in to deciding how long you will have to keep your Ignition Interlock Device. But they vary greatly state-by-state, so it’s important to clearly understand the laws and requirements from the beginning of your monitoring.

Basic Ignition Interlock FAQs

DUI Frequency is a Major Consideration

The length of time you have to keep your Ignition Interlock Device is typically correlated with the number of DUI convictions you have received. Some states  become progressively harsh with Ignition Interlock Device requirements after the first offense.

Regardless of which penalties apply, it’s important for Ignition Interlock users to stay current with device calibrations and all other requirements. In most states, missing these appointments can result in your Ignition Interlock Device not working properly, making you subject to additional penalties.

Stay on Top of Your Testing

Alcohol Levels Also Make a Difference

In virtually every state, the legal limit for DUI is blood alcohol content (BAC) of .08 or higher. However, there are a number of exceptions. For example:

• In Utah, the legal BAC limit is .05.
• Commercial drivers typically have a limit of .04.
• For drivers under 21, the levels range from zero tolerance to .08.

Higher BAC levels typically require harsher penalties. Some states have established the threshold for felony DUI as any level higher than 0.15. This often has a great impact on the required length of Ignition Interlock Device usage. Felony DUI often involves longer use.

Misdemeanor DUI vs. Felony DUI

Judicial Discretion and Other Factors

In many jurisdictions (unless there are mandatory minimums), judges or legal authorities often have a great deal of discretion regarding DUI penalties. This can include fines, classes, rehabilitation programs, community service and (of course) the use of Ignition Interlock Devices.

Judges will often consider:

• Previous DUI convictions or other criminal history.
• Impact on any victims, such as death or injury.
• Other extraneous factors, such as whether children are present in the vehicle.

Another potential pitfall is not adhering to the terms of your probation or monitoring. Violations can sometimes result in an extended requirement for Ignition Interlock.
