Key Points
- A BAC of 0.03% or higher counts as being under the influence (Article 44(4) of the Road Traffic Act).
- For a first offense, 0.03% to under 0.08% carries up to 1 year in prison or a fine of up to KRW 5 million; 0.08% to under 0.2% carries 1 to 2 years in prison or a fine of KRW 5 million to 10 million; 0.2% or higher carries 2 to 5 years in prison or a fine of KRW 10 million to 20 million.
- 0.03% to under 0.08% leads to license suspension (100 penalty points); 0.08% or higher, or an accident in which someone was injured, leads to license revocation.
- If driving is essential to your livelihood and other requirements are met, such as a BAC of 0.1% or lower, you can file an objection within 60 days of the decision to seek a reduced penalty.
BAC bands and penalties
Article 44(1) of the Road Traffic Act prohibits driving a motor vehicle, etc. while under the influence, and Article 44(4) sets the threshold at a BAC of 0.03%. The penalties for a first offense are set out by band in Article 148-2(3).
| BAC band | Prison | Fine |
|---|---|---|
| 0.03% to under 0.08% | Up to 1 year | Up to KRW 5 million |
| 0.08% to under 0.2% | 1 to 2 years | KRW 5 million to 10 million |
| 0.2% or higher | 2 to 5 years | KRW 10 million to 20 million |
| Situation | Action | Disqualification |
|---|---|---|
| 0.03% to under 0.08% | Suspension, 100 penalty points | None |
| 0.08% or higher | Revocation | 1 year |
| 0.03% or higher with an accident causing injury | Revocation (criminal liability under the Act on Special Cases Concerning the Settlement of Traffic Accidents (the “Traffic Accident Settlement Act”, 교통사고처리법) or for death and injury due to dangerous driving is added) | 2 years |
License actions are based on Annex 28 of the Enforcement Rule of the Road Traffic Act. The disqualification period is the time after revocation during which you cannot obtain a new license: 1 year for a first-offense revocation (Article 82(2)7 of the Road Traffic Act), 2 years for a revocation caused by an accident while drunk (Article 82(2)6(b)), and also 2 years where a prior DUI record makes this a second or later violation (Article 82(2)6(a)).
Are e-scooters, bicycles and motorcycles different?
You also may not ride a personal mobility device such as an electric kick scooter, or a bicycle, while under the influence. In that case, however, the penalty is much lighter than for a car: a fine of up to KRW 200,000, detention, or a petty fine (Article 156(11)). Motorcycles (motorized bicycles) and construction machinery are treated the same as cars.
What to check about the stop and afterward
- The gap between when you stopped driving and when you were tested · BAC keeps rising for about 30 to 90 minutes after drinking. If there was a long gap, your BAC at the moment you were driving may have been lower than the reading.
- Procedure before the test · Check whether you were allowed to rinse residual alcohol from your mouth with water and whether there are maintenance records for the device.
- Blood test · If you dispute the breath test result, you can consent to a blood draw for a second measurement (Article 44(3)). However, the blood test result becomes the final figure, so think carefully before asking for one.
- Where and how far the car moved · In some cases, such as moving a car a short distance in a parking lot while waiting for a designated driver, the issue is whether the place was a "road" or whether the act was "driving" at all.
A realistic goal for a first case
A first offense with no accident and a moderate reading usually ends with a summary order (a fine imposed on the documents without a full trial). When the amount is set, the reading, the distance driven, the circumstances that led to driving (whether you had called a designated driver, whether there was an urgent matter), remorse, and efforts not to reoffend are all considered. Submitting records of alcohol treatment, a plan to sell the car or use public transportation, and a certificate of completing a prevention course from the investigation stage onward can affect the outcome.
For public officials, teachers, professional drivers and others whose job status depends directly on the type of sentence, we also look from the start at whether to request a formal trial and what the disciplinary standards are.
The license issue is handled separately
License revocation or suspension is an administrative action taken by the commissioner of the metropolitan or provincial police agency, so it proceeds separately from the criminal case. If driving is the key means of supporting your family, your BAC did not exceed 0.1%, and there was no injury accident, no refusal to be tested, and no prior DUI record, you can file an objection within 60 days of the decision. If it is accepted, the revocation is reduced to a 110-day suspension (General Standards, item (f) of Annex 28). Separately from an objection, you can also file an administrative appeal.
