“Can I still drive to work?” In a DUI consultation, that question usually arrives before any question about jail, because the fine is a number but the license is a life. The answer in Georgia often runs through an ignition interlock device: a breath tester wired to the starter, installed at the driver’s expense, that will not let the engine turn over until it gets a clean sample. Who has to install one, how long it stays, and what the whole arrangement costs are not trivia questions. They shape the first strategic decision in the case, and that decision has a 30-day fuse.
Who Georgia Actually Puts on an Interlock
Georgia’s mandatory interlock line sits at the second DUI conviction within five years, measured arrest date to arrest date. That is later than most states draw it; the majority now attach an interlock requirement to a first conviction, so the driver who picks up a second DUI on Pio Nono Avenue eighteen months after the first is in narrower company but deeper trouble. Under O.C.G.A. § 40-5-64.1 and the Department of Driver Services rules, that second conviction brings a license suspension of at least 18 months. The first 120 days are a hard suspension with no driving of any kind. After the 120 days, the driver can apply for an ignition interlock device limited driving permit, and the device stays on for 12 months of monitored driving. After 12 clean months, the interlock restriction comes off the permit itself, which can then be renewed while the driver works toward full reinstatement. Some older pages still cite an eight month device period; that tier applied only to incidents in the first half of 2013, and for anything since July 2013 the rule is 12 months.
A first conviction does not carry an automatic interlock mandate. A sentencing judge can still order one as a condition of probation, and, more importantly, many first-time drivers end up choosing the device anyway, in the week after the arrest, for reasons the next section explains.
The 30-Day Choice After an Arrest
When an officer takes a license at a DUI arrest and issues a Form 1205, an administrative suspension starts moving on its own track, separate from the criminal case. A driver with no DUI conviction in the past five years then faces a fork: appeal the administrative suspension, or waive that hearing, install an interlock through a state-approved provider, and take the interlock permit instead. The window to act is 30 days from the arrest, and the device must be installed before the Department of Driver Services will issue the permit, which matters because providers commonly need several business days to schedule an installation. Wait three weeks to decide and the choice has quietly made itself.
The fork is not symmetrical, and this is where drivers get hurt. Take the state-administered test and register over the limit, and the interlock permit route runs 4 months. Refuse the test, and the same route runs 12 months, and that clock does not care how the criminal case ends; win the DUI outright and the refusal-route permit still runs its full year. The election also waives the administrative hearing, a hearing that sometimes holds real leverage.
That is a strategic decision with an expiration date, not a form to fill out. Before the 30-day window closes, call 478-257-6333. A Prine Law Group attorney can weigh the appeal against the permit on the facts of the stop, in a free consultation, while every option is still on the table.
The Clock and the Bill
| The route | Interlock time | The condition underneath |
|---|---|---|
| First arrest, test taken, over the limit, permit elected | 4 months | No DUI conviction in prior 5 years; elected within 30 days of arrest |
| First arrest, test refused, permit elected | 12 months | Same window; runs regardless of how the criminal case ends |
| Second conviction within 5 years | 12 months on the permit | Opens only after a 120-day hard suspension, inside an 18-month minimum suspension |
The money is the part nobody mentions in the movies. The driver pays for the device: published Georgia pricing from approved providers such as Intoxalock runs roughly $55 to $100 as a deposit plus an installation fee of about $30, then a monthly lease and monitoring cost in the range of $50 to $75. State-side fees layer on top: the permit itself, the removal certificate when the term ends, and license reinstatement together add several hundred dollars over the life of the permit. Monthly monitoring visits are mandatory, and the provider downloads the device’s data for the Department of Driver Services to review, so a missed visit or a flagged sample is not a private event.
The permit is also fragile. A conviction for a moving violation while driving on it revokes it, and a first revocation means a six-month wait before applying for a license at all.
Where the Defense Actually Fits
The interlock is a consequence, not the case. The lever sits upstream, in two places: the week-one decision between the administrative appeal and the permit, and the criminal case itself, where the stop, the testing, and the charge can all be contested or negotiated before a conviction ever triggers the mandatory track. That work runs through the firm’s criminal defense practice, and when the license fallout is the sharpest edge of the case, through traffic and license defense. The device is manageable. The record that puts it there for five more years is the thing worth fighting about.
Common Questions About Ignition Interlocks in Georgia
Does a first DUI in Georgia require an ignition interlock?
Not automatically. Georgia’s mandatory interlock attaches to a second conviction within five years. A judge can order one as a probation condition, and a first-time driver can voluntarily elect the interlock permit within 30 days of arrest to keep driving while the case proceeds.
Do I keep the interlock if I win my DUI case?
On the refusal-election route, yes: the 12-month permit runs regardless of the criminal outcome, because electing it waived the administrative hearing. That trade is exactly why the 30-day decision deserves legal advice before it is made.
What happens if the device flags a sample or I miss a monitoring visit?
The data goes to the Department of Driver Services through the provider’s monthly downloads, so problems surface quickly. A moving-violation conviction while on the permit revokes it, and a first revocation brings a six-month wait for any license. Talk to an attorney before assuming a flagged event is minor, and never attempt to trick or bypass the device.
After a second DUI, how long before I can drive at all?
The first 120 days of the suspension are a hard suspension with no driving. After that, the interlock permit path opens, with the device required for 12 months.
