Cobb County DUI Lawyer

A DUI arrest in Georgia is a serious event that triggers two separate legal proceedings — a criminal case in court and an administrative license suspension through the Georgia Department of Driver Services. You have only 30 days from the date of your arrest to challenge the suspension of your driver’s license, and the decisions you make in the first hours and days after your arrest can determine the outcome of your entire case.

Attorney David Williamson of Williamson Legal, P.C. is a former felony prosecutor who now defends clients against DUI charges throughout Cobb County, Forsyth County, Fulton County, and metro Atlanta. He understands how prosecutors build DUI cases because he used to prosecute them — and he uses that experience to fight for his clients. Call (770) 884-1485 for a free consultation.

Georgia DUI Law: DUI Per Se vs. DUI Less Safe

Georgia law recognizes two distinct types of DUI under O.C.G.A. § 40-6-391:

DUI Per Se (O.C.G.A. § 40-6-391(a)(5)): It is illegal to drive with a blood alcohol concentration (BAC) of 0.08% or higher. The State does not need to prove that your driving was impaired — the BAC level alone is sufficient for conviction. For commercial vehicle drivers, the threshold is 0.04% under O.C.G.A. § 40-6-391(a)(6). For drivers under 21, the threshold is 0.02% under O.C.G.A. § 40-6-391(k).

DUI Less Safe (O.C.G.A. § 40-6-391(a)(1)): It is illegal to drive while under the influence of alcohol to the extent that it is “less safe” for the person to drive. This charge does not require a specific BAC — the State can prosecute based on the officer’s observations, field sobriety test performance, driving behavior, and other evidence of impairment. This means you can be convicted of DUI even with a BAC below 0.08%.

DUI — Drugs (O.C.G.A. § 40-6-391(a)(2) and (a)(6)): It is also illegal to drive under the influence of any drug — including prescription medications, marijuana, and controlled substances — to the extent that it is less safe to drive. Drug DUI cases rely on officer observations, Drug Recognition Expert (DRE) evaluations, and blood or urine test results.

Georgia’s Implied Consent Law

Under O.C.G.A. § 40-5-55, every person who drives on Georgia roads has given “implied consent” to chemical testing of their blood, breath, urine, or other bodily substances for the purpose of determining the presence of alcohol or drugs. When an officer arrests you for DUI, they are required to read you the Georgia Implied Consent Notice, which informs you that:

Refusal to submit to testing will result in a one-year suspension of your driver’s license. Submitting to testing and registering a BAC of 0.08% or higher (or 0.02% for under-21 drivers, or 0.04% for commercial drivers) will result in a one-year license suspension.

The implied consent notice and the officer’s compliance with its requirements are frequently challenged in DUI cases. If the officer failed to read the notice correctly or failed to follow proper procedures, the test results — or the consequences of refusal — may be challenged.

The 30-Day Rule: Protecting Your Driver’s License

This is one of the most critical deadlines in Georgia DUI law. Under O.C.G.A. § 40-5-67.1, after a DUI arrest where you either refused chemical testing or tested above the legal limit, the arresting officer will confiscate your license and issue a 1205 form (DS-1205). You have exactly 30 days from the date of your arrest to file an appeal with the Georgia Department of Driver Services to request an Administrative License Suspension (ALS) hearing. If you do not file within 30 days, your license will be automatically suspended.

David Williamson files ALS hearing requests immediately upon being retained to protect your driving privileges. In many cases, the ALS hearing also provides a valuable opportunity to cross-examine the arresting officer under oath before the criminal case goes to trial — locking in testimony that can be used in your defense.

First Offense DUI Penalties in Georgia

Under O.C.G.A. § 40-6-391(c), a first DUI conviction within a ten-year “look-back” period carries:

Jail time: 10 days to 12 months (minimum 24 hours must be served, though the judge may suspend the remaining jail time and place you on probation)
Fines: $300 to $1,000 (plus mandatory surcharges that typically bring the total to approximately $1,500 to $2,100)
Probation: Up to 12 months
Community service: Minimum 40 hours
DUI Risk Reduction Program (DUI school): Required completion of a state-approved 20-hour course
Clinical substance abuse evaluation: Required
License suspension: Up to 12 months, though a limited driving permit may be available after 120 days for a first offense

A first offense DUI is classified as a misdemeanor in Georgia. However, the consequences extend far beyond the courtroom — a DUI conviction will appear on background checks, can increase your insurance rates dramatically, and may affect your employment and professional licenses.

Second Offense DUI Penalties in Georgia

Under O.C.G.A. § 40-6-391(c), a second DUI conviction within ten years carries significantly harsher penalties:

Jail time: 90 days to 12 months (minimum 72 hours must be served in custody)
Fines: $600 to $1,000 (plus surcharges)
Probation: Up to 12 months
Community service: Minimum 30 days (240 hours)
DUI Risk Reduction Program: Required
Clinical evaluation and treatment: Required completion of a substance abuse treatment program
License suspension: 3 years (a limited permit may be available after 120 days with installation of an ignition interlock device under O.C.G.A. § 42-8-111)
Ignition Interlock Device (IID): Required for at least 12 months
Vehicle license plate surrender: Required under O.C.G.A. § 40-6-391.2
Publication: The court may order publication of your name, address, and photograph in the local newspaper

A second offense DUI is still classified as a misdemeanor, but the mandatory minimums are severe and judges have limited discretion to go below them.

Third Offense DUI Penalties in Georgia

A third DUI conviction within ten years is classified as a “high and aggravated misdemeanor” under O.C.G.A. § 40-6-391(c), carrying:

Jail time: 120 days to 12 months (minimum 15 days must be served in custody)
Fines: $1,000 to $5,000 (plus surcharges)
Probation: Up to 12 months
Community service: Minimum 30 days (240 hours)
License revocation: 5 years (a limited permit with an ignition interlock device may be available after 2 years)
Ignition Interlock Device: Required
Clinical evaluation and treatment: Required
Habitual violator designation: Under O.C.G.A. § 40-5-58, a third DUI within five years results in being declared a habitual violator, making it a felony to drive on a revoked license
Publication: Mandatory publication of name, address, and photograph

Fourth and Subsequent DUI Offenses

Under O.C.G.A. § 40-6-391(c)(2)(C), a fourth or subsequent DUI conviction within ten years is a felony, carrying 1 to 5 years in prison, fines of $1,000 to $5,000, and a mandatory minimum of 90 days served in custody. The habitual violator designation and all enhanced penalties apply.

Aggravated DUI Circumstances

Certain circumstances elevate the severity of a DUI charge in Georgia:

DUI with a Child Passenger: Under O.C.G.A. § 40-6-391(l), driving under the influence with a child under 14 years of age in the vehicle constitutes a separate offense of child endangerment for each child in the vehicle. Each count is a separate misdemeanor carrying up to 12 months in jail.

DUI Causing Serious Injury: Under O.C.G.A. § 40-6-394, causing serious bodily injury while driving under the influence is a felony carrying 1 to 15 years in prison.

DUI Causing Death — First Degree Vehicular Homicide: Under O.C.G.A. § 40-6-393(a), causing the death of another person while driving under the influence is a felony carrying 3 to 15 years in prison.

Hit and Run DUI: Leaving the scene of an accident while under the influence can result in additional felony charges under O.C.G.A. § 40-6-270.

CDL and Commercial Vehicle DUI

Commercial drivers face stricter DUI standards under both Georgia and federal law. Under O.C.G.A. § 40-6-391(a)(6), the BAC limit for commercial vehicle operators is 0.04% — half the standard limit. A DUI conviction will result in a one-year disqualification of your CDL for a first offense and a lifetime disqualification for a second offense under O.C.G.A. § 40-5-151. Even if the DUI occurred in your personal vehicle, your CDL is at risk. For commercial drivers, a DUI charge is a direct threat to your livelihood.

Underage DUI (Under 21)

Georgia’s “zero tolerance” law under O.C.G.A. § 40-6-391(k) sets the BAC limit at 0.02% for drivers under 21. A violation results in a license suspension of at least 6 months for a first offense and 12 months for a second offense. Underage drivers who register a BAC of 0.08% or higher face the same adult DUI penalties in addition to the zero tolerance consequences.

Defenses Against Georgia DUI Charges

David Williamson has successfully defended hundreds of DUI cases using strategies including:

Challenging the Traffic Stop: Under the Fourth Amendment and the Georgia Constitution, an officer must have reasonable articulable suspicion of a traffic violation or criminal activity to initiate a traffic stop. If the stop was not legally justified, all evidence obtained afterward — including field sobriety tests and chemical test results — can be suppressed.

Field Sobriety Test Challenges: The three Standardized Field Sobriety Tests (SFST) — the Horizontal Gaze Nystagmus (HGN), Walk and Turn, and One Leg Stand — must be administered according to strict NHTSA protocols. Improper administration, uneven road surfaces, medical conditions, footwear, weather, and other factors can undermine the reliability of these tests. David Williamson scrutinizes field sobriety testing in every DUI case.

Breath Test Challenges: The Intoxilyzer 9000 used in Georgia must be properly calibrated, maintained, and operated by a certified operator. Under the Georgia Bureau of Investigation’s Division of Forensic Sciences regulations, specific procedures must be followed — including a 20-minute observation period before testing. Violations of these procedures can form the basis for suppression of breath test results.

Blood Test Challenges: Blood draws must be performed by qualified medical personnel. Chain of custody must be maintained. The GBI crime lab must follow proper analytical procedures. Any break in the chain or deviation from protocol can be challenged.

Implied Consent Notice Challenges: If the officer failed to read the implied consent notice correctly or at the appropriate time, the consequences of refusal or the test results themselves may be challenged under O.C.G.A. § 40-5-67.1.

Rising BAC Defense: Alcohol takes time to absorb into the bloodstream. If there was a significant delay between driving and testing, your BAC at the time of testing may have been higher than your BAC at the time of driving. Expert testimony can establish that you were below the legal limit when you were actually behind the wheel.

Reduction to Reckless Driving: In appropriate cases, David Williamson negotiates for a reduction of DUI charges to reckless driving under O.C.G.A. § 40-6-393 — sometimes called a “wet reckless.” A reckless driving conviction avoids the DUI-specific consequences including the mandatory DUI surcharges, clinical evaluation, DUI school, and the DUI notation on your criminal record.

What to Expect After a DUI Arrest in Georgia

At the Scene: You will be placed under arrest, handcuffed, and transported to the county jail for booking. The officer will read you the Georgia Implied Consent Notice and request a chemical test (breath or blood). Your license will be confiscated and you will receive a 1205 form that serves as a temporary driving permit for 30 days.

Within 30 Days: You or your attorney must file an appeal with the Department of Driver Services to prevent automatic license suspension. This is a hard deadline — missing it means your license is suspended with no hearing. Call David Williamson immediately after your arrest so he can file this appeal.

Arraignment: You will appear in court for arraignment, where charges are formally read and you enter a plea. David Williamson will enter a not guilty plea and begin building your defense.

Discovery and Investigation: Your attorney will obtain all evidence — the arrest report, dash cam and body camera footage, field sobriety test video, chemical test results, calibration records, the officer’s training records, and any other relevant materials.

Pretrial Motions and Negotiations: Based on the evidence, David Williamson may file motions to suppress illegally obtained evidence, challenge the traffic stop, or negotiate with the prosecutor for a reduction to reckless driving or other favorable disposition.

Trial or Resolution: If the case cannot be resolved favorably through negotiation, David Williamson is fully prepared to try your case before a judge or jury.

Frequently Asked Questions About DUI in Georgia

Should I refuse the breathalyzer test during a DUI stop?

This is one of the most common questions people have, and there is no one-size-fits-all answer. Under Georgia’s implied consent law (O.C.G.A. § 40-5-55), refusing a chemical test after arrest will result in a one-year license suspension — regardless of whether you are ultimately convicted of DUI. However, refusing also means the State will have less evidence to use against you at trial. David Williamson can advise you on how the refusal affects your specific case during a free consultation.

Can I get a DUI reduced to reckless driving in Georgia?

Yes, in many cases. A reduction to reckless driving under O.C.G.A. § 40-6-393 is one of the most favorable outcomes in a DUI case. Factors that influence whether a reduction is possible include your BAC level, whether there was an accident, your driving record, and the strength of the State’s evidence. David Williamson has negotiated numerous DUI reductions in Cobb County and throughout metro Atlanta.

Will I lose my license after a DUI arrest in Georgia?

Your license is at risk from two separate proceedings. The administrative suspension through the Department of Driver Services can be challenged if you file an appeal within 30 days of your arrest under O.C.G.A. § 40-5-67.1. A criminal DUI conviction also carries license suspension. An experienced attorney can fight both proceedings to protect your driving privileges.

How much does a DUI lawyer cost in Georgia?

Attorney fees for DUI defense vary based on the complexity of the case, whether it is a first or subsequent offense, and whether the case goes to trial. Williamson Legal, P.C. offers free initial consultations so you can understand your options and the likely cost before making a commitment. Given the potential consequences of a DUI conviction — including jail time, fines exceeding $2,000, license suspension, increased insurance rates for years, and a permanent criminal record — hiring an experienced DUI attorney is one of the most important investments you can make.

What is the 10-day rule for DUI in Georgia?

There is actually a 30-day rule, not a 10-day rule. Under O.C.G.A. § 40-5-67.1, you have 30 days from the date of your DUI arrest to file an appeal of the administrative license suspension with the Georgia Department of Driver Services. Many people confuse this with the old 10-day rule that existed before July 1, 2017. The current deadline is 30 days, but you should act as quickly as possible — call David Williamson immediately after your arrest.
