Georgia Ignition Interlock Device: Voluntary IID Permit, Fees & BAC Thresholds (2026)

What Is a Voluntary Ignition Interlock Device in Georgia?

A voluntary interlock device is a breath-alcohol sensor wired into your vehicle's ignition system. Before the engine will start, you must blow a clean breath sample into the device. If the sensor detects alcohol at or above a preset threshold, the vehicle will not start. In Georgia, this device lets DUI drivers keep limited driving privileges after a refusal or an over-limit breath test reading.

The key word is "voluntary." A voluntary IID is one a driver elects to install by filing with the Georgia Department of Driver Services. In exchange, the driver keeps limited driving privileges during the administrative license suspension period. This differs from a court-mandated IID, which a judge imposes as part of a DUI sentence after conviction. The voluntary interlock election governs this process. It took effect on July 1, 2017. The law allows eligible drivers to waive their right to an OSAH administrative hearing. In return, they receive a 12-month interlock-restricted permit.

In our experience with Georgia DUI clients, the biggest mistake is assuming the voluntary interlock is the only path. Often an OSAH appeal is the stronger choice depending on the arrest facts. At William C. Head, PC, we review every client's DDS Form 1205 and arrest details before recommending a course of action. The 30-day window from the date of arrest closes fast. Speaking with a DUI attorney early is critical.

How the Driver's License Gets Handled by Georgia DDS & ALS Options

After a Georgia DUI arrest, the arresting officer's police department transmits the DDS Form 1205 and the seized driver's license to the Georgia Department of Driver Services in Conyers, Georgia. This transmission happens when a driver blows over the legal alcohol limit. It also happens when a driver refuses to take the breath test, blood test, or urine test that the arresting officer requested.

A recent U.S. Supreme Court case altered these rules. In Birchfield v. North Dakota, the Court changed when law enforcement can ask for blood testing. Under Georgia's implied consent law, most DUI refusal cases now involve refusal to take the breath alcohol test on the Intoxilyzer 9000.

The Georgia Department of Driver Services in Conyers is the state headquarters for driver license issuance and suspension or revocation. For a DUI refusal, DDS shreds the plastic license once it is processed. For a DUI per se – the driver took the breath alcohol test and blew over the legal limit – DDS files the Georgia driver's license in its administrative license unit.

The rules for issuing or denying a license are rigid and precise. They do not allow variation or discretion. DDS staff can only apply the rules mechanically. Calling DDS offices to complain accomplishes nothing. Drivers should avoid getting a driving on suspended license charge after a Georgia DUI arrest.

Under administrative license suspension procedures, Georgia drivers have a strict 30-day window from the date of arrest to respond to the pending administrative license suspension. During that window, the driver faces two main options.

The first option is to file a traditional OSAH appeal. This requests a hearing before an administrative law judge. The judge will decide whether the suspension is valid. If the driver wins, the license is restored with no restrictions. If the driver loses, a hard suspension takes effect. This means no driving at all for 12 months on a refusal case.

The second option is the voluntary IID election. The driver waives the OSAH hearing, pays the $25 interlock permit fee, and surrenders the physical license to DDS. In return, DDS issues an interlock-restricted permit. This permit allows limited driving for the full 12-month period.

The practical difference matters. A hard suspension bars all vehicle operation – no exceptions for work, school, medical appointments, or any other purpose. The voluntary IID permit allows the driver to operate a vehicle equipped with an interlock device for these purposes:

• Driving to and from work
• Attending school or medical appointments
• Traveling to IID service center appointments
• Essential household and family needs

During the IID period, the driver's physical license remains surrendered to DDS. The interlock-restricted permit serves as the only valid driving credential.

How to Elect the Voluntary IID Permit After a Georgia DUI Refusal

Georgia drivers who want to keep driving after a DUI refusal can elect the voluntary IID permit. This option avoids risking a hard suspension at an OSAH hearing. The process follows a specific sequence. Missing any step can cost you the right to drive for a full year.

Step 1: File the IID Election Within 30 Days of Arrest

Within 30 days of your DUI arrest, submit the required paperwork to the Georgia Department of Driver Services. This filing formally waives your right to an OSAH administrative hearing. Once filed, this election is generally irrevocable. You cannot change your mind later and request a hearing instead. Consulting a DUI attorney before making the choice is critical.

Step 2: Surrender Your License and Receive the Interlock Permit

Pay the $25 interlock permit fee to DDS. Your physical Georgia driver's license is surrendered. DDS issues an interlock-restricted permit in its place. This permit allows you to drive only vehicles equipped with an approved ignition interlock device.

Step 3: Select a DDS-Approved IID Provider and Schedule Installation

Choose from the list of Georgia DDS-approved interlock providers. You have only 10 days from permit issuance to complete installation. Do not wait – scheduling delays can push you past the deadline.

Step 4: Drive With the Device Installed for the Full 12 Months

The interlock must remain installed for the entire 12-month period. There is no early removal option. You cannot drive any vehicle that does not have an interlock device installed. Commercial motor vehicles cannot be operated at all during this period, even with an IID.

Step 5: Comply With Monthly Calibration Appointments

Your IID provider requires regular calibration and data download appointments – typically once per month. The provider reports compliance data to DDS. Missed appointments or violations can extend the IID period.

Step 6: Apply for Reinstatement at the End of the Term

After the full 12 months, pay the interlock permit restriction removal fee to Georgia DDS. The fee is $90 by mail or $100 in person. Once DDS processes the removal, you can have the device uninstalled. You will receive your unrestricted Georgia driver's license.

The trade-off is straightforward. You give up your right to challenge the suspension at an OSAH hearing. In return you keep limited driving privileges for a year. For some drivers, this is the smarter path. For others, especially those with strong suppression arguments or officer credibility issues, fighting at OSAH may be the better strategy. A Georgia DUI lawyer can evaluate your arrest facts and advise which option gives you the strongest position.

Georgia Ignition Interlock Fees and Costs in 2026

The financial side of a voluntary IID permit adds up over 12 months. These are 2026 Georgia figures. State-specific ignition interlock fees vary widely across the U.S. Figures cited elsewhere may not apply to a Georgia case. Fees may also vary by approved provider.

Here is what Georgia drivers can typically expect to pay:

• Installation fee: $70 to $150 (one-time, paid to the IID provider)
• Monthly monitoring and calibration: $70 to $100 per month
• DDS interlock permit fee: $25 (one-time, paid to DDS)
• Removal fee: $90 by mail or $100 in person (paid to DDS at the end of the 12-month term)
• Total estimated 12-month cost: $900 to $1,400

Georgia law provides some relief for drivers who cannot afford IID costs. Under fee reduction for indigent drivers, indigent drivers may qualify for a fee reduction program. This program lowers monthly monitoring costs. Ask your IID provider or your DUI attorney about eligibility.

Georgia DDS-approved IID vendors include Smart Start, Intoxalock, LifeSafer, and Draeger. William C. Head, PC does not endorse any specific provider. Compare pricing and service locations before choosing. Monthly calibration appointments require an in-person visit. Proximity matters.

What BAC Will Fail an Ignition Interlock Device?

Many drivers wonder what BAC will fail an interlock. In Georgia, an ignition interlock device is calibrated to lock the ignition at a breath alcohol concentration of 0.020 BAC or higher. This is well below the 0.08 legal driving limit.

Most Georgia DDS-approved providers use a tiered reading system. A breath sample between 0.010 and 0.019 BAC typically triggers a "warn" reading. The device logs the event but still allows the vehicle to start. Any reading at or above 0.020 BAC is a "fail." The ignition locks, and the event is recorded.

Once the vehicle is running, the device requires rolling retests at random intervals during the drive. You will hear a tone or see a prompt. You must provide a clean breath sample within a few minutes. A rolling retest failure does not shut the engine off while you are driving – that would be dangerous. Instead, it logs the fail and may trigger the vehicle's horn or lights. You pull over and turn off the engine.

Failed tests are reported to DDS during your next calibration appointment. Multiple failures or patterns of non-compliance can extend the IID period. Extensions add months of device rental costs and restricted driving.

Common false-positive triggers include alcohol-based mouthwash, certain fermented foods, energy drinks, and residual mouth alcohol from recent eating or drinking. The recommended protocol is to rinse your mouth with water and wait at least 15 minutes before providing a breath sample. Thresholds and reporting practices may vary by vendor and by whether the driver holds a court-ordered or voluntary permit.

Talk to a Georgia DUI Attorney Before You Elect an Ignition Interlock

The voluntary IID election is a one-time decision with 12-month consequences. Once you waive your OSAH hearing rights, there is no going back. In many cases, an OSAH appeal could win the license back outright. This means no interlock, no monthly fees, and no restricted permit.

At William C. Head, PC, we have spent more than a decade defending Georgia DUI cases. We review the IID versus OSAH trade-off for clients across metro Atlanta. Every case is different. The right choice depends on your arrest facts, your breath test results, and the officer's conduct during the stop. If you face a DUI charge in Sandy Springs, Alpharetta, Marietta, Roswell, Athens, or elsewhere in Georgia, call for a free consultation.
