IID Installation Cost

Ignition Interlock Device Costs in Utah: Installation, Monthly Fees, and Total Expense

The cost of an ignition interlock device in Utah includes an upfront installation fee and ongoing monthly monitoring charges. Installation typically costs $100 to $200 per device. Monthly fees range from $70 to $150 per device, covering the device lease, calibration, data downloads, and reporting to the Driver License Division. Over the mandatory 18-month period for a standard first offense, total costs range from approximately $1,360 to $2,900. For the 36-month period required for aggravated offenses, total costs range from approximately $2,620 to $5,600.

These costs are the defendant’s responsibility and are not covered by the court, insurance, or government programs. Understanding the full financial picture helps you plan for the requirement and choose a provider that fits your situation. Glen Neeley has advised DUI clients on interlock costs and compliance since 1998.

Detailed Cost Breakdown

Installation Fee: $100 to $200

The installation fee covers the physical installation of the IID in your vehicle, initial calibration, and training on how to use the device. Installation is performed by an approved interlock provider at one of their service locations. The appointment typically takes 1 to 2 hours.

If you have multiple vehicles that require the IID, you pay the installation fee for each vehicle. Two vehicles double the installation cost.

Monthly Monitoring Fee: $70 to $150

The monthly fee covers the device lease, required calibration at each monitoring appointment, data download and reporting to the Driver License Division, and any necessary maintenance. Monitoring appointments are typically required every 30 to 60 days, depending on the provider and the court’s requirements.

Monthly costs vary by provider, location, and the specific device model. Shopping among approved providers can help you find the most competitive rate. All providers must be approved by the Utah Department of Public Safety.

Removal Fee: $50 to $100

When the interlock period is complete and the Driver License Division authorizes removal, the provider charges a removal fee to uninstall the device and restore the vehicle to its original condition. This one-time fee is typically lower than the installation fee.

Total Cost Over the Interlock Period

For an 18-month requirement on a single vehicle: Installation ($100-$200) plus 18 months of monitoring ($1,260-$2,700) plus removal ($50-$100) equals $1,410 to $3,000 total.

For a 36-month requirement on a single vehicle: Installation ($100-$200) plus 36 months of monitoring ($2,520-$5,400) plus removal ($50-$100) equals $2,670 to $5,700 total.

These estimates assume a single vehicle. Multiple vehicles multiply the costs proportionally. Additional charges for missed appointments, lockouts, or violation reporting can increase the total further.

The interlock cost is in addition to all other DUI-related expenses, including court fines and surcharges, substance abuse assessment and treatment costs, increased insurance premiums, attorney fees, and any lost income due to the arrest and case resolution.

Ways to Manage Interlock Costs

Compare prices among approved providers. Utah has multiple approved IID providers, and their pricing varies. Get quotes from at least two or three providers before choosing. The cheapest option may not always be the best in terms of reliability and customer service, but significant price differences between providers are common.

Reduce the number of vehicles requiring IID installation. If you own multiple vehicles, consider temporarily taking some out of operation during the interlock period. The IID must be installed on every vehicle you own or regularly operate, so reducing the number of active vehicles directly reduces cost.

Ask about payment plans. Some providers offer monthly payment arrangements or reduced rates for financial hardship. Not all providers offer these options, but it is worth asking.

Avoid violations that extend the interlock period. Failed breath tests, missed monitoring appointments, and tampering evidence can extend the IID requirement beyond the original 18 or 36 months. Each month of extension adds $70 to $150 in monitoring costs.

Frequently Asked Questions About IID Costs

Choosing an Approved Provider

Compare total cost including installation, monthly monitoring, and removal. Service location proximity matters for 30-to-60-day monitoring appointments. Customer reviews indicate reliability.

Financial Impact on Defendants

Monthly costs of $70 to $150 are significant with existing fines and insurance increases. Planning should begin during case resolution.

The investment in compliance is always less expensive than non-compliance consequences.

Insurance Implications of an Interlock Requirement

An ignition interlock requirement in Utah is connected to your driving record and typically accompanies an SR-22 insurance filing requirement. The SR-22 is a certificate of financial responsibility that your insurance company files with the Utah Driver License Division. Carrying both an IID and SR-22 increases your insurance premiums, sometimes substantially depending on your prior driving history and the insurance carrier.

The duration of elevated insurance costs often extends beyond the interlock period itself. Many carriers reassess rates based on the full timeline of the DUI-related events on your record. We review these financial impacts with clients during consultation because the total cost of a DUI conviction in Utah extends well beyond fines and court fees. Understanding these costs early helps you plan and budget appropriately.

What Happens at a Calibration Appointment

Calibration appointments are required at regular intervals, typically every 30 to 60 days depending on the service provider and court order. During calibration, the service technician downloads the data log from your device, recalibrates the sensor accuracy, and inspects the unit for tampering or damage. The appointment usually takes 30 to 60 minutes.

The data download is one of the most important parts of the calibration visit. The device records every breath sample, every failed test, every missed rolling retest, and any attempts to tamper with the unit. This data is reported to the Utah Driver License Division and, in some cases, to your probation officer or the court. If the data shows violations, consequences can follow quickly. Our office reviews data reports with clients to identify potential issues before they escalate.

Daily Life with an Ignition Interlock Device in Utah

Living with an ignition interlock device (IID) changes your morning routine. Before starting the vehicle, you provide a breath sample into the handset. The device takes a few seconds to analyze the sample. If it reads below the preset threshold, the vehicle starts normally. If the reading is above the limit, the device locks the ignition for a timed waiting period before you can retest.

Cold weather in Utah creates additional considerations. During winter months, the device may take longer to warm up and provide accurate readings. We advise our clients to allow extra time before scheduled departures, particularly during December through February when temperatures in the Salt Lake Valley and surrounding areas regularly drop below freezing. The handset should be stored in a location where it will not freeze overnight.

Passengers in your vehicle may ask about the device. There is no legal prohibition against having passengers while driving with an IID, and you are not required to explain the device to anyone. However, the device will prompt rolling retests during your drive, which means you will need to provide additional breath samples while the vehicle is in motion. These retests are timed, and missing one can trigger a violation.

Common Interlock Myths Versus Reality

Several misconceptions surround ignition interlock devices. One common myth is that mouthwash or certain foods will cause a failed test. While some products containing alcohol can produce a brief elevated reading, the device is calibrated to detect ethanol at specific concentrations. Rinsing your mouth with water and waiting a few minutes before testing typically resolves residual mouth alcohol from food or hygiene products.

Another myth is that someone else can blow into the device for you. Modern IID units use camera verification and breath pattern recognition to prevent circumvention attempts. Attempting to have another person provide a breath sample is a violation that carries serious consequences, including extended interlock periods and potential criminal charges. The device is designed to ensure that the person providing the sample is the driver.

Some drivers believe that disconnecting the battery will reset the device or erase violation data. This is incorrect. Power disconnections are logged and reported. Tampering with the device or its power source creates additional violations that can extend your restricted driving period and result in further penalties from the Utah Driver License Division.
