How much does an ignition interlock device cost per month?

An ignition interlock device (IID) typically costs $70 to $150 for initial installation and $60 to $110 per month for monitoring, calibration, and data downloads. Most states require monthly calibration appointments at an authorized service center. Over a 12-month IID requirement, the total cost ranges from $790 to $1,470 including installation. Some states also charge a monthly administrative fee of $10 to $30 on top of the device cost. If you fail a breath test or miss a calibration, additional fees and an extension of the IID period may apply.

The True Cost of a License Suspension

A license suspension costs far more than the reinstatement fee posted on your state's DMV website. The fee itself ranges from $10 in Arizona to $1,200 in Massachusetts for DUI-related suspensions. But the reinstatement fee is typically the smallest part of the total bill. The real financial impact comes from three additional costs that most people do not anticipate until they start the reinstatement process.

First, most states require SR-22 insurance (or FR-44 in Florida and Virginia) for three years after a DUI suspension. This certificate of financial responsibility signals to insurers that you are a high-risk driver, which increases your premium by 30% to 224% depending on your state. Over three years, that insurance increase alone can cost $2,700 to $10,000. Second, if your suspension was DUI-related, most states now mandate an ignition interlock device (IID) that costs $70 to $150 to install and $60 to $110 per month. Third, navigating the reinstatement process often requires an attorney, adding $1,000 to $7,000 to the total.

SR-22 Insurance: The Biggest Hidden Cost

SR-22 is not a type of insurance. It is a form your insurer files with the state to prove you carry at least the minimum required auto insurance. The filing fee is a modest $15 to $35. The real cost is what happens to your premium once the insurer classifies you as high-risk. Eight states (Delaware, Kentucky, Minnesota, New Mexico, New York, North Carolina, Oklahoma, and Pennsylvania) do not require SR-22 filing, but their insurers still raise rates significantly after a DUI.

North Carolina has the highest average insurance increase at 224% for drivers with a DUI on record. California and Michigan follow at 130% each. On the other end, Utah sees increases averaging 30%, and New Hampshire around 40%. Florida and Virginia require an FR-44 form instead of SR-22, which mandates even higher liability limits, pushing insurance costs even higher in those two states.

The critical rule with SR-22 is continuity. If your coverage lapses for any reason, even by a single day, your insurer must notify the state. Your license gets re-suspended immediately, and the 3-year SR-22 clock restarts from zero. A missed payment can cost you years of progress.

Ignition Interlock Devices: Cost Breakdown

As of 2026, 34 states require ignition interlock devices for all first-time DUI offenders. The device connects to your vehicle's ignition and requires a clean breath sample before the engine will start. Installation costs $70 to $150 at an authorized service center. Monthly monitoring and calibration fees run $60 to $110. Some states add a monthly administrative fee of $10 to $30 on top of the device provider's charges.

The required IID period for first DUI offenses ranges from 4 months in Maine to 24 months in Massachusetts. The most common requirement is 6 to 12 months. Failed breath tests, missed calibration appointments, or tampering attempts can extend the IID period and add penalty fees. Over a typical 12-month IID requirement, the total cost runs $790 to $1,470 including installation, monthly fees, and removal.

States that do not require IID for a standard first DUI offense include Indiana, North Dakota, Rhode Island, and South Dakota. However, even in these states, judges can order IID installation at their discretion, and the requirement becomes mandatory for second offenses in every state.
