Overview of Georgia DUI Laws in 2026 (O.C.G.A. § 40-6-391)

Georgia DUI laws make it illegal for any person to drive, operate, or be in actual physical control of a moving vehicle while under the influence of alcohol, drugs, toxic vapors, or any combination of these substances. The primary Georgia DUI statute is O.C.G.A. § 40-6-391, which defines every form of impaired driving offense in the state.

Under GA DUI laws, an Atlanta DUI arrest can result in two distinct charges:

• DUI Per Se – driving with a blood alcohol concentration (BAC) at or above the legal limit, regardless of actual impairment.
• DUI Less Safe – driving under the influence of alcohol or drugs “to the extent that it is less safe” for you to drive, even if your BAC is below 0.08%.

Georgia ranks among the top 10 strictest states in the nation for DUI penalties. The most painful aspect of Georgia DUI laws is that a DUI conviction creates a permanent, lifetime criminal record. Georgia law does not permit expungement, record restriction, or any other means of removing a DUI from your record.

Critical 30-day deadline after a metro Atlanta DUI arrest: If you have been arrested for DUI in Atlanta or any surrounding metro Atlanta county, you have only 30 calendar days from the date of arrest to request an Administrative License Suspension (ALS) hearing. Failing to act within this window results in automatic suspension of your driving privileges. Call an Atlanta DUI lawyer immediately.

Georgia BAC Limits by Driver Type

Georgia DUI laws set different legal BAC limits depending on the driver’s age and the type of vehicle being operated. The chart below summarizes the legal alcohol limit for every driver type under current GA DUI laws.

The Georgia legal alcohol limit has been lowered several times over the past four decades: from 0.15% to 0.12%, then to 0.10%, and finally to the current 0.08% in 2001. Remember that even with a BAC below 0.08%, you can still be charged with DUI Less Safe if an officer determines your ability to drive is impaired.

BAC Estimation Chart: How Many Drinks Put You Over the Atlanta DUI Limit?

The estimation below gives a general guide to blood alcohol concentration based on body weight and the number of standard drinks consumed within one hour. One standard drink equals 12 oz. of regular beer, 5 oz. of table wine, or 1.5 oz. of 80-proof distilled spirits.

• 120 lb. driver: roughly 0.08% BAC after 2 drinks in one hour
• 140 lb. driver: roughly 0.08% BAC after 3 drinks in one hour
• 160 lb. driver: roughly 0.08% BAC after 3 to 4 drinks in one hour
• 180 lb. driver: roughly 0.08% BAC after 4 drinks in one hour
• 200 lb. driver: roughly 0.08% BAC after 4 to 5 drinks in one hour
• 220 lb. driver: roughly 0.08% BAC after 5 drinks in one hour

Individual results vary based on gender, food intake, metabolism, medications, and other factors. This chart is for educational purposes only and is not a defense to a Georgia DUI charge.

Warning about over-pouring: A standard drink is precisely measured. Restaurant wine pours of 6 to 8 ounces and craft beers at 7% to 10% ABV can easily double the alcohol content of a “standard” drink. One extra drink can push many Atlanta drivers from legal to well over the Georgia DUI limit.

Georgia DUI Penalties: 1st, 2nd, 3rd and Felony DUI Offenses

Georgia DUI laws impose progressively harsher penalties for each subsequent offense. Misdemeanor DUI penalties use a 5-year lookback period, while felony DUI classification uses a 10-year lookback, both calculated from arrest date to arrest date.

Note: Fines listed above do not include mandatory state surcharges, court costs, probation supervision fees, DUI Risk Reduction Program tuition, ignition interlock fees, or other assessments – these can easily add thousands of dollars to the total cost of a Georgia DUI conviction.

Driver’s License Suspension and the Critical 30-Day Rule

After a DUI arrest in metro Atlanta, your Georgia driver’s license faces two separate suspension threats:

• Administrative License Suspension (ALS) – triggered automatically by your arrest. You must request a hearing or elect an ignition interlock device permit within 30 calendar days, or your license is suspended. Governed by O.C.G.A. § 40-5-67.1.
• Court-Ordered Suspension – imposed upon conviction as part of your sentence, per the penalty chart above.

Getting Your Georgia Driver’s License Back After a DUI

License reinstatement in Georgia depends on the number of your offense and is governed primarily by O.C.G.A. § 40-5-55 and O.C.G.A. § 40-5-64.1:

• 1st DUI offense: a license suspension limited driving permit may be available immediately for Georgia-only driving. Full reinstatement is possible after 120 days upon completing the DUI Risk Reduction Program and paying the reinstatement fee.
• 2nd DUI offense: 12-month hard suspension with no driving at all, followed by a limited permit with a mandatory ignition interlock device.
• 3rd DUI offense: you are declared a habitual violator with a 5-year revocation. No limited permit is available for at least 24 months. A probationary license may be possible after 2 years.

Important – DUI-drug convictions: If you are convicted of DUI-drugs (rather than DUI-alcohol), Georgia law does not allow any limited driving permit. This makes drug-related DUI charges particularly devastating to your ability to work, attend school, and maintain daily life in metro Atlanta.

When Is DUI a Felony in Georgia?

Under Georgia DUI laws, a DUI becomes a felony on the 4th conviction within a 10-year period, measured by arrest dates. This has been the law since July 1, 2008 (O.C.G.A. § 40-6-391(c)(1)(iv)). DUI can also be charged as a felony when it involves serious injury by vehicle (O.C.G.A. § 40-6-394) or vehicular homicide (O.C.G.A. § 40-6-393).

A Georgia felony DUI conviction carries:

• 1 to 5 years in state prison (the judge may probate all but 90 days)
• $1,000 to $5,000 in fines, plus state surcharges
• 5-year driver’s license revocation (habitual violator status)
• 60 days of community service (may be suspended if imprisoned for 3 or more years)
• Mandatory ignition interlock device upon license reinstatement
• Publication of your photograph and name in the local newspaper

A felony DUI conviction also carries serious collateral consequences, including potential loss of voting rights during incarceration, inability to possess firearms under federal law, immigration consequences for non-citizens, and significant barriers to employment, housing, and professional licensure.

Aggravating Factors That Increase Georgia DUI Penalties

Georgia DUI laws allow for enhanced penalties when certain aggravating factors are present at the time of arrest:

• High BAC (0.15% or above): significantly increased jail time, longer ignition interlock requirements, and higher fines.
• Accidents causing injury: can result in separate felony charges for serious injury by vehicle under O.C.G.A. § 40-6-394.
• Child endangerment: DUI with a passenger under 14 years old triggers a separate child endangerment charge for each child in the vehicle.
• School zone DUI: enhanced penalties apply for DUI committed in or near a Georgia school zone.
• Hit and run: leaving the scene of a DUI accident adds felony hit-and-run charges under O.C.G.A. § 40-6-270.
• Prior DUI history: each prior conviction increases the mandatory minimum penalties imposed by the judge.

Underage DUI in Georgia: Zero Tolerance Law

Georgia enforces a zero tolerance law for drivers under age 21, codified in O.C.G.A. § 40-6-391(k). The legal BAC limit for underage drivers is just 0.02%, effectively meaning any measurable alcohol in a young driver’s system can result in an underage DUI charge in Georgia.

Consequences for an underage DUI in Atlanta and metro Atlanta counties include:

• BAC of 0.08% or higher: 12-month license suspension with no limited permit available
• BAC under 0.08% or test refusal: 6-month license suspension with no limited permit
• Driver under 16 years old: not eligible for any driver’s license until age 17
• Mandatory DUI Risk Reduction Program
• Clinical alcohol or drug evaluation and treatment if indicated
• Potential dismissal from college, loss of scholarships, and immigration consequences

How to Fight a DUI in Atlanta and the Metro Atlanta Counties

Georgia DUI cases are highly defensible when handled by an experienced Atlanta DUI lawyer. Common DUI defense strategies our attorneys use to fight Atlanta DUI charges include:

• Challenging the traffic stop: officers must have reasonable articulable suspicion to initiate a traffic stop. Without it, all evidence obtained may be suppressed.
• Attacking breath test accuracy: Georgia’s breath test Intoxilyzer 9000 device has known margins of error. Improper calibration, maintenance failures, RFI interference, and operator errors can invalidate breath test results.
• Questioning field sobriety tests: standardized field sobriety tests (HGN, walk-and-turn, one-leg stand) are subjective and affected by medical conditions, age, weight, fatigue, weather, road surface, and footwear.
• Rising blood alcohol defense: your BAC continues to rise after your last drink. You may have been under 0.08% while driving but tested over the limit at the station.
• Three-hour rule: Georgia law requires the state to test BAC within three hours of driving. Results obtained outside this window face greater scrutiny under O.C.G.A. § 40-6-392.
• Improper implied consent warnings: officers must read the Georgia implied consent notice correctly and timely. Errors in the reading can result in test results being excluded.
• Negotiating reduced charges: in many cases, a skilled Atlanta DUI attorney can negotiate a reduction to reckless driving, avoiding the permanent consequences of a DUI conviction. You may also be able to file a motion to suppress evidence if your Fourth Amendment rights were violated.

Why Fighting a First DUI Offense in Atlanta Matters

A first DUI offense in Georgia follows you for life. It cannot be expunged or record-restricted. For professionals, students, military service members, CDL drivers, and anyone with decades of career ahead of them, fighting to avoid that conviction is critical. A skilled Atlanta DUI lawyer can often identify weaknesses in the prosecution’s case that lead to dismissal, acquittal, or reduction of charges to reckless driving.

Key Georgia DUI Statutes You Should Know
