Ignition Interlock Device Requirements After a DUI in Nevada

A lot happens in the immediate aftermath of a DUI arrest. Driving under the influence means facing criminal charges, fines, and a license suspension. However, one that many people don’t know about is the ignition interlock device requirement. For anyone convicted of DUI in Nevada, there’s a good chance they’ll be driving with one of these installed in their vehicle for months or even years.

What Is an Ignition Interlock Device?

An ignition interlock device (often called an IID) is a breathalyzer hardwired into the ignition. Before the car will start, the driver has to blow into it and register a clean breath sample. If the device detects alcohol above the threshold (usually 0.02% BAC), the car won’t start.

It doesn’t stop there. Most IIDs also require “rolling retests”, which are periodic breath samples while driving. If the driver fails one or doesn’t provide a sample in time, the device logs a violation and triggers alerts, which can mean a horn honking or lights flashing until the driver pulls over and addresses it.

When Is an IID Required in Nevada?

Under Nevada law, an IID is mandatory for most DUI convictions. For a first-offense DUI, the court is required to order an IID for at least 185 days, on top of any license suspension period.

For a second DUI offense within seven years, the mandatory IID period is one to three years. A third offense or felony DUI can result in an IID requirement lasting one to three years as well, and the court can extend it further depending on the circumstances.

The clock doesn’t always start the moment you’re convicted. You generally can’t begin the IID period until your license is reinstated, which means the total time before you’re fully free of the device can be longer than the requirement itself suggests.

Who Pays for an IID and How Much Does It Cost?

The person convicted of DUI pays for the IID. Installation usually runs $70 to $150, and monthly monitoring fees range from $60 to $100 depending on the provider. Over a six-month requirement, drivers are looking at several hundred dollars at minimum. Over a two-year requirement, the costs can climb past $1,500.

Low-income individuals can apply for reduced fees, but they have to request it and qualify. It’s not automatic.

What about IID Requirement Violations?

Violations get reported. Every failed test, missed rolling retest, or tampering attempt gets logged and transmitted to the monitoring authority. Violations can mean extended IID requirements, additional probation conditions, or even revoked driving privileges.

Trying to get around the device by having someone else blow into it is also a crime in Nevada, and it’s treated as a tampering offense. That can mean additional charges on top of existing DUI penalties.

Fighting a DUI Charge Is Worth It

The IID requirement affects every driver in a household who shares the vehicle; it costs money every month, and it comes with its own compliance obligations that can create new legal problems if they’re not met.
