Georgia’s Legal Limit for Drinking and Driving: BAC Laws Explained

Georgia's Legal Limit for Drinking and Driving

Georgia's limit for drunk driving is a blood alcohol concentration (BAC) of 0.08% for drivers age 21 and over. Drivers under 21 face a 0.02% threshold under Georgia's zero tolerance rule. A commercial license holder operating a commercial vehicle is held to a lower 0.04% threshold. Georgia's DUI statute, O.C.G.A. § 40-6-391, sets each of these numbers.

Drunk driving laws in the US vary from state to state, and every state defines its own terms and acronyms for the offense. Georgia uses DUI, short for driving under the influence. The rest of this page explains how Georgia applies that number and what happens after an arrest.

The alcohol level for drunk driving matters because it changes what the state has to prove. At or above 0.08%, prosecutors can rely on the test result itself. The number becomes the case. Below that figure, the state must build its proof from what the officer saw and heard at the roadside.

That is why 0.08% is not a safe harbor. A driver can still be arrested, charged, and convicted below the limit under Georgia's less safe theory. If an officer believes alcohol or drugs made you a less safe driver, the arrest can happen at 0.06%, at 0.04%, or with no test result at all. Prescription medication and marijuana can support the same charge.

The under-21 and commercial thresholds work the same way, only lower. A 19-year-old driver who registers 0.02% has already crossed the line Georgia set for that age group. A CDL holder who registers 0.04% behind the wheel of a commercial vehicle has crossed the line that applies to that license, and the consequences reach the license itself, not just the criminal case.

Driving or Operating – Can You Get a DUI If Your Car Is Turned Off?

States word this differently. Some reach only actual driving. Others reach anyone operating or controlling the vehicle. Georgia sits in the second group. O.C.G.A. § 40-6-391(a) says a person shall not drive "or be in actual physical control of any moving vehicle" while under the influence. So a driver can face a charge without the car moving when the officer walks up. Actual physical control is a fact question. Where the keys were, where the driver was sitting, and whether the engine was running all matter.

What's the Difference Between DUI "Less Safe" and DUI "Per Se"?

In Georgia, there are two ways to violate the law: DUI less safe and DUI "per se". While a person can be charged with Impairment DUI based on if the arresting officer is convinced that the driver is impaired enough to be a less safe driver, a DUI "per se" is charged after the chemical test shows the driver's blood alcohol content (BAC) to be 0.08% or over.

Both theories come from the same statute, O.C.G.A. § 40-6-391, but they are proven in completely different ways. A per se count turns entirely on the measured alcohol level for drunk driving. The chemical test result is the state's proof, and the officer's opinion about your driving matters far less. A less safe count requires no number at all. It rests on observations: the driving pattern, the odor of an alcoholic beverage, slurred speech, bloodshot eyes, performance on field sobriety evaluations, and any admissions made at the scene.

Prosecutors in Georgia routinely charge both counts from a single arrest. That way, if the test result falls out of the case, the less safe count may survive on its own.

The distinction matters to the defense because each count invites a different challenge. A per se count may be contested by examining the testing device, its maintenance and calibration history, the operator's certification, and whether the observation protocol was followed before the breath sample. A less safe count is usually contested on the reliability of subjective observations and the conditions at the roadside. Poor lighting, uneven pavement, traffic noise, weather, footwear, injuries, and age can all affect how a driver performs on those evaluations. Which challenges apply depends on the circumstances of the stop and the evidence the state actually has.

Implied Consent and Administrative License Suspension

A driver's license is a privilege, not a constitutional right. Georgia conditions that privilege on consent to chemical testing. By driving here, you give implied consent to a state-administered test of your blood, breath, urine, or other bodily substances after a DUI arrest. Refusing that test starts a suspension of your driving privileges.

Georgia's implied consent law requires the officer to read a specific implied consent notice after the arrest. The notice states which test the officer is requesting, warns what happens if you refuse, and tells you that you may get an independent test of your own. A refusal does not end the case. It triggers an administrative suspension of your driving privileges. The notice set out in O.C.G.A. § 40-5-67.1 warns that refusing blood or urine testing may be offered into evidence at trial. It says nothing of the kind about a breath test refusal.

Two separate tracks then run at the same time. The administrative track handles your license through the Georgia Department of Driver Services. The criminal track handles the charge in court. Winning one does not automatically resolve the other. A driver can beat the criminal charge and still lose driving privileges, or the reverse, depending on how each proceeding goes.

A short statutory deadline applies to challenging the administrative suspension after arrest. The window is measured in days, not weeks, and missing it generally forfeits the challenge no matter how strong the underlying defense is. Do not take that deadline from a blog post or a friend. Contact a lawyer immediately after an arrest so the filing gets made in time.

In any DUI case in Georgia, the Georgia Department of Driver Services (DDS) takes care of the license suspension. It can and does so without any criminal court hearing and conviction. It is called an administrative license suspension. Penalties are only part of the picture. If you are wondering how long does DUI stay on record in Georgia, the answer differs sharply from the point windows that apply to ordinary traffic citations.

Georgia DUI Penalties: Fines, Jail, and License Consequences

Courts hand down DUI penalties under O.C.G.A. § 40-6-391. What a judge may impose depends on how many prior convictions fall within the ten-year lookback period, plus the facts of the case and the driver's history. Georgia treats a first, a second, and a third conviction within ten years as separate tiers with different exposure.

Fines. A first conviction typically carries a fine of up to $1,000. A second conviction within ten years carries a higher statutory minimum, with the same $1,000 ceiling. A third conviction within ten years can reach $5,000. Those figures are the base fines only. Georgia adds mandatory surcharges and court costs on top, which often push the real amount owed well past the number printed in the statute.

Jail. Every tier carries a mandatory minimum jail period. Judges may probate much of that time on a first offense, but the minimum period of actual confinement generally cannot be waived. Maximum exposure on a first conviction runs up to 12 months in county jail. Repeat convictions carry longer exposure, and a fourth DUI conviction within ten years is charged as a felony in Georgia.

License consequences. A conviction suspends driving privileges for a set period that grows with each tier. Limited driving permits may be available in some situations, usually with conditions attached, and eligibility narrows for repeat offenders. Reinstatement requires paperwork, fees, and proof that court-ordered programs were completed.

Programs and supervision. Sentences typically include at least 40 hours of community service, probation, and completion of a DUI Alcohol or Drug Use Risk Reduction Program, commonly called DUI school. A clinical evaluation for alcohol or drug dependency is required for repeat offenders, and any treatment the evaluator recommends becomes mandatory. Repeat offenders may also face an ignition interlock device requirement as a condition of driving again, and vehicle forfeiture is possible in some repeat cases.

The collateral consequences last longer than the sentence. Insurance rates usually climb sharply. Employers who run background checks see the conviction, and a CDL holder can lose the license that pays the bills. A Georgia DUI conviction cannot be expunged or restricted from your record, so it stays visible for life. Other states label the same conduct differently, and our comparison of driving under the influence vs driving while intoxicated explains what changes when a Georgia driver crosses a state line.

DUI Drugs

A first conviction for driving under the influence of a drug or marijuana suspends the license for at least 180 days under O.C.G.A. § 40-5-75. That runs on top of whatever the court imposes. At the end of the 180 days, reinstatement requires proof that the DUI Risk Reduction Program was finished, plus the reinstatement fee. Permit eligibility during a drug-related suspension is narrow and turns on the exact code section used, so ask a lawyer before you assume you can drive to work.

Texting and Driving Laws in Georgia

Georgia's Hands-Free Act governs phone use behind the wheel. Drivers may not hold or support a phone with any part of the body while operating a vehicle. That includes propping it against a shoulder or resting it in your lap. Texting and driving is illegal whether the car is moving or stopped in traffic at a red light.

Hands-free use is the permitted alternative. Bluetooth, a dashboard mount, a single touch to start or end a call, and voice-to-text dictation all stay within the law. Watching or recording video while driving is not allowed.

A violation carries a fine plus points against your license. Both escalate with repeat violations inside a set period, so a second or third citation costs more than the first and adds more points. Because the statute sets those amounts and lawmakers adjust them, check the current figures rather than relying on numbers you read online.

There is a practical overlap that matters for impaired driving cases. A phone in the hand is easy for an officer to see, and that observation frequently supplies the reason for the traffic stop in the first place. Once the car is stopped, the officer may begin a DUI investigation based on what happens next. One stop can produce a hands-free citation and a DUI charge together.

Underage Drinking – Minor in Possession (MIP)

Georgia uses a zero tolerance rule for drivers under 21. On a first DUI conviction, O.C.G.A. § 40-5-57.1 suspends the license for six months when the reading is under 0.08%. At 0.08% or more, the suspension runs twelve months. A second conviction within five years brings an eighteen-month suspension. Either way the case is a criminal DUI, not a civil ticket.

That 0.02% threshold is low enough that a single drink can reach it, depending on the driver's body and how recently the drink was finished. Parents are often surprised by how little it takes.

An underage suspension carries its own reinstatement requirements. The driver generally must wait out the suspension period, pay reinstatement fees, and complete any program the court or DDS requires before driving legally again. Early reinstatement options are limited for younger drivers.

The consequences reach past the license. A conviction may affect college enrollment decisions, scholarship eligibility, athletic eligibility, and financial aid. Insurance for a young driver is expensive already, and a DUI on the record can make coverage difficult to keep at any reasonable price. Because these cases can follow a young person for years, families facing an underage charge should get legal advice before any court date.

How Much Alcohol Reaches the Legal Limit?

No drink count reliably predicts a BAC result. Body weight, biological sex, food in the stomach, hydration, medications, the rate of consumption, and the time elapsed since the last drink all move the number. So does the pour itself. A craft beer or a heavy-handed cocktail can carry two or three times the alcohol of a standard drink, so "two beers" may mean very different things from one bar to the next.

Rules of thumb are unreliable for the same reason. One drink per hour, coffee, food, a cold shower, or a wait in the parking lot may not bring anyone under the limit for drunk driving. Consumer breath gadgets sold online are not calibrated to the standard the state uses, and a reading from one of them proves nothing in court.

Alcohol also keeps absorbing after the last drink. That means a BAC can still be climbing while you drive and while you sit at the roadside. A driver who felt fine leaving may test higher an hour later. And a driver who tests below the threshold can still face a less safe charge based on the officer's observations.

Treat this as general information about how these cases work, not advice about your own test result. If you have a breath or blood number in hand, talk to an attorney about what it actually shows rather than trying to assess it yourself.

Talk With an Atlanta DUI Lawyer About Your BAC Test

A reading at or over the limit for drunk driving is where the state's case starts, not where it ends. The test itself can be examined. Device maintenance and calibration records, the operator's certification, the observation period before the breath sample, sample handling and chain of custody for a blood draw, and whether the implied consent notice was read correctly are all fair subjects for a defense to review. Whether any of them help depends on the facts of your case.

Frequently Asked Questions

What Is the Legal Alcohol Level for Drunk Driving in Georgia?

For drivers 21 and over, it is a BAC of 0.08%. Drivers under 21 are limited to 0.02% under Georgia's zero tolerance rule, and commercial drivers operating a commercial vehicle are limited to 0.04%. O.C.G.A. § 40-6-391 sets all three thresholds.

Can You Get a DUI in Georgia With a BAC Under 0.08%?

Yes. Georgia allows a less safe charge when an officer concludes that alcohol or drugs made you a less safe driver, regardless of the number. That charge can be brought with a low test result or with no chemical test at all. Prescription drugs and marijuana can support it too.

What Happens if You Refuse a Breath Test in Georgia?

A refusal triggers an administrative suspension of your driving privileges through the Georgia Department of Driver Services, separate from anything that happens in criminal court. Georgia's implied consent notice warns that refusing blood or urine testing may be used as evidence at trial. It does not say that about a breath test refusal. A short deadline applies to challenging that suspension, so contact a lawyer right away rather than waiting for a court date.

Is Texting While Driving Illegal in Georgia?

Yes. Under Georgia's Hands-Free Act, you may not hold or support a phone with any part of your body while driving, and texting is prohibited even when stopped in traffic. Voice-to-text and hands-free calling remain legal. Violations bring a fine and points, and both increase for repeat offenses.

Does a Georgia DUI Conviction Ever Come Off Your Record?

No. A DUI conviction in Georgia cannot be expunged or restricted, so it stays on your criminal history permanently. The ten-year lookback period is a separate concept: it governs how prior convictions raise the sentence on a new charge, not whether the old conviction disappears.

Should I Talk to a Lawyer Before My First Court Date?

Yes, and preferably within days of the arrest. Deadlines on the license side run from the arrest date, not the court date. An early conversation also preserves options for reviewing the test evidence while records are still readily available.
