Ignition Interlock Device Requirement

You probably have a good idea of how an Ignition Interlock works, which is to measure your breath alcohol concentration level (BrAC). The device will prompt you for a breath test before you can start your vehicle. If your BrAC is at a certain level or higher, your vehicle won’t start. The Ignition Interlock will also prompt for random running retests during your drive. An Ignition Interlock Separates Drinking From Driving® so you can get back on the road safely and legally if you have a DUI arrest and/or conviction.

When a court or state office orders the device, they are the oversight authority of your Ignition Interlock requirement period. Your court documents, or the paperwork you receive from your DMV for example, will show you how long you’ll need your Ignition Interlock in most cases. The device can be a requirement as a DUI conviction and/or to reinstate your driving privileges.

You may find that the Interlock requirement for a first-time DUI conviction without aggravating circumstances can vary anywhere from a few months to a year, however, this period can change, and not all states require Ignition Interlocks for first DUI cases. If there are other factors such as having a minor in your vehicle at the time of your DUI, or if you refused your test, your Ignition Interlock period can be extended. Second, third, or subsequent DUIs will also have longer Ignition Interlock requirement periods.

Regardless of how long you’ll need the Ignition Interlock, remember that correctly finishing the program will lead to a more seamless experience with your device.

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 statesbecome progressively harsh with Ignition Interlock Device requirements after the first offense.

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 motor vehicle.

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