Just arrested for DUI in Georgia, or worried about a recent stop? Use our free BAC calculator below to estimate your blood alcohol content at the time you were driving, then read what it means for your case under Georgia law.
Critical if you were arrested: Georgia’s implied consent law gives you only 30 days from your arrest date to request an ALS hearing or your license is automatically suspended, regardless of how your criminal case turns out. The clock is already running.
Key facts about Georgia DUI law:
- A BAC of 0.08% or higher is a per se DUI; the state needs no other proof of impairment
- Drivers under 21 face a zero-tolerance limit of just 0.02%
- CDL holders are held to a stricter 0.04% limit while on duty
- A BAC of 0.15% or higher triggers aggravated DUI with mandatory minimums
- BAC continues rising for up to 90 minutes after your last drink, you may have been legal when you started driving
- Paying a DUI fine without contesting it is a criminal conviction on your permanent record

A DUI charge in Georgia is not a minor traffic ticket; it is a criminal charge that can follow you for the rest of your life. The consequences of a conviction include fines of up to $1,000 or more, mandatory jail time, license suspension, DUI school, community service, increased insurance premiums, and a permanent mark on your criminal record that can affect employment, housing, and professional licensing. Many people assume that if their BAC was over the limit, there’s nothing to be done, but that assumption costs defendants dearly every day.
An experienced Georgia DUI attorney knows how to scrutinize every detail of your case: whether the traffic stop was constitutionally justified, whether the arresting officer followed proper implied consent procedures, whether the breathalyzer device was correctly calibrated and maintained, and whether field sobriety tests were administered according to NHTSA standards. Any one of these issues, if mishandled by law enforcement, can result in evidence being suppressed or charges being reduced or dismissed entirely.
DIY DUI- Why It’s A Bad Idea
Attempting to handle a DUI case yourself, also known as pro se representation, puts you at an immediate disadvantage. Prosecutors handle DUI cases every single day. They know the procedures, the judges, the plea norms, and the evidentiary rules inside and out. A self-represented defendant typically has no working knowledge of Georgia’s administrative license suspension process, the 30-day deadline to request an ALS hearing, or how to file the motions that could protect their rights.
Missing the ALS hearing deadline alone results in an automatic license suspension regardless of the outcome of your criminal case. Beyond procedure, a skilled DUI lawyer brings negotiation leverage that an unrepresented defendant simply does not have; the ability to pursue a reduction to reckless driving (sometimes called a “wet reckless”), negotiate alternative sentencing, or mount a full defense at trial.
The cost of hiring a qualified DUI attorney is almost always far less than the long-term financial and personal cost of a conviction. If you have been charged with DUI anywhere in Georgia, the single most important thing you can do for your future is to call an experienced DUI defense attorney before you say another word to law enforcement or the court.
Understanding Blood Alcohol Content and Georgia DUI Law
Blood alcohol content (BAC) is the measurement law enforcement uses to determine whether a driver is legally impaired. In Georgia, a BAC of 0.08% or higher is sufficient for a per se DUI charge under O.C.G.A. § 40-6-391; meaning the state does not need to prove you were actually impaired, only that your BAC met the threshold. For drivers under 21, Georgia’s zero-tolerance law kicks in at just 0.02%, and commercial vehicle operators face a stricter limit of 0.04%.
What many drivers don’t realize is that BAC rises for up to 90 minutes after your last drink, meaning you may feel fine behind the wheel while your BAC is still climbing. Factors like body weight, biological sex, food consumption, hydration, medications, and individual metabolism all influence how quickly alcohol enters your bloodstream and how long it stays there. This BAC calculator uses the widely accepted Widmark formula to give you a general estimate, but no online tool can replicate a certified breathalyzer or blood draw. Use it to educate yourself, not to make driving decisions.
Tips If You’ve Been Drinking: How to Stay Safe and Protect Yourself Legally
The best decision you can make after drinking is a simple one; don’t drive. But beyond that obvious rule, there are practical steps that can protect both your safety and your legal standing.
First, always arrange a sober ride before you start drinking, whether that’s a designated driver, a rideshare app like Uber or Lyft, or a taxi. If you find yourself unexpectedly needing a ride, most Georgia cities have rideshare coverage available within minutes. Second, if law enforcement does stop you, know your rights: you are required to provide your license, registration, and proof of insurance, but you have the right to remain silent beyond that. Politely decline to answer questions about how much you’ve had to drink, as anything you say can and will be used against you in court. Third, understand that field sobriety tests in Georgia are voluntary, you may decline them without automatic legal penalty. Bear in mind, though, refusal can still be noted by officers.
If asked to submit to a breathalyzer, be aware that Georgia’s implied consent law means refusal can result in an automatic license suspension. Finally, if you are arrested, do not resist, do not argue, and contact a qualified Georgia DUI attorney as soon as you are able. The decisions made in the first hours after an arrest can significantly shape the outcome of your case.
