Drunk Driving & Traffic Accidents

In Korea, the statutory penalty for drunk driving is set by your blood alcohol concentration and any prior offense within the last 10 years. Within that range, the core of your defense is checking how the test was carried out and preparing sentencing materials that courts actually accept.

When you may need advice

  • I was caught at a DUI checkpoint, and I already paid a drunk driving fine a few years ago
  • While waiting for a designated driver, I moved my car a short distance to park it
  • I blew into the breathalyzer several times, but I was booked for refusing the test
  • I had a minor collision after drinking, and the other driver went to the hospital
  • I left the scene of an accident and was later contacted about a hit-and-run
  • I drive for a living, and losing my license is my biggest worry

Relevant laws

Road Traffic Act (도로교통법) Article 44 (Prohibition of Driving While Intoxicated)

Driving is prohibited at a blood alcohol concentration of 0.03% or higher. Drivers must comply with a police officer's breath test. If you disagree with the result, you can be tested again, for example by a blood sample taken with your consent. Drinking more alcohol after driving in order to obstruct the test is also prohibited.

Road Traffic Act Article 148-2 (Penalties)

The statutory penalty depends on the blood alcohol range. It is increased if you violate the law again within 10 years from the date a sentence of a fine or heavier became final. Refusing the test or obstructing it is punishable by 1 to 5 years in prison or a fine of KRW 5 million to KRW 20 million.

Act on Special Cases Concerning the Settlement of Traffic Accidents (교통사고처리 특례법) Articles 3 and 4

Even if a traffic accident causes injury through occupational negligence, prosecution is not allowed if the victim does not want the driver punished or if the driver has comprehensive insurance. However, this does not apply to the 12 exceptions, such as running a red light, crossing the center line and drunk driving, or to fleeing the scene. The insurance exception also does not apply if the victim suffers serious injury.

Act on the Aggravated Punishment of Specific Crimes (특정범죄 가중처벌 등에 관한 법률) Articles 5-11 and 5-3

Injuring a person while unable to drive normally because of alcohol is punishable by 1 to 15 years in prison or a fine of KRW 10 million to KRW 30 million. Causing death is punishable by life imprisonment or at least 3 years in prison. If a driver flees without helping the victim and the victim is injured, the statutory penalty is at least 1 year in prison or a fine of KRW 5 million to KRW 30 million.

Statutes are summarized. The official Korean text is available at the Korea Law Information Center (law.go.kr).

    Statutory penalty

    Legal basis
    Road Traffic Act Article 148-2(2)

Applies to driving a motor vehicle or tram (not personal mobility devices such as e-scooters). The 10 years are counted from the date a sentence of a fine or heavier became final, including sentences that have since expired. Based on current law on the Korea Law Information Center (the government's official law database) as of October 2026.

Your level and any offense in the last 10 years set the penalty

For a first offense, your blood alcohol range sets the statutory penalty. If you were previously sentenced to a fine or heavier for drunk driving, the first thing to check is whether this offense falls within 10 years from the date that sentence became final. A repeat offense within 10 years falls under a provision with a minimum of 1 year in prison, even if your level is low.

Even if your prior offense was more than 10 years ago, it is still considered at sentencing as a similar prior conviction. If you find the earlier judgment or summary order (약식명령) and note the exact date it became final, we can quickly confirm which provision applies.

We check the test timing and circumstances one by one

What is punished is your level at the time you were driving. Depending on the gaps between your last drink, when you started driving and when you were tested, and how far the result is from the legal threshold, there may be room to dispute your level at the time of driving. However, the mere possibility that your level was still rising is not enough to decide the case.

We also check whether you were given a chance to rinse your mouth before the breath test, whether you asked for a blood test, and whether the times in the police report on the intoxicated driver (주취운전자 정황진술보고서) match what actually happened. If you were booked for test refusal because you could not complete the test after several attempts, we need to carefully go back over the situation and what the officer told you.

  • When you started and stopped drinking, and how much you drank
  • Where and when you started driving, how far you drove, and why you drove
  • Designated driver call records and card payment records
  • The time you were stopped, the time you were tested, and how many tests were taken

If there was an accident, different laws apply

For an ordinary traffic accident, prosecution is not allowed if you have comprehensive insurance or if the victim does not want you punished. However, an accident while drunk driving is one of the exceptions under the Act on Special Cases Concerning the Settlement of Traffic Accidents, so you can be punished regardless of insurance or a settlement. If you are found to have been unable to drive normally, dangerous driving causing injury under the Aggravated Punishment Act applies.

After an accident, you must stop immediately, help the injured and give your contact details (Road Traffic Act Article 54). If you leave the scene without doing so, failure to take measures after an accident or fleeing after causing injury also becomes an issue, and this part often makes the punishment the heaviest. Write down why you left the scene and how you were contacted afterward, with dates and times.

License penalties are handled separately from the criminal case

Suspension or revocation of a driver's license is an administrative penalty imposed by the provincial police agency, so it proceeds separately from criminal punishment. The standards are in Attached Table 28 of the Enforcement Rules of the Road Traffic Act. At a blood alcohol level of 0.03% or higher but below 0.08%, you receive 100 penalty points and your license is suspended; as a rule, each point counts as one day of suspension. Your license is revoked if your level was 0.08% or higher, if you caused an accident that injured someone while drinking, or if you refused the test. If you have a prior drunk driving record, a level of just 0.03% or higher leads to revocation. After revocation, you cannot get a new license for a set disqualification period.

If your license was revoked for drunk driving again within 5 years from the date of a previous violation, you must get a conditional license with an ignition interlock device to drive again (Road Traffic Act Article 80-2). If you drive for a living, you can file an objection asking the provincial police agency to reduce the penalty within 60 days from the date of the decision. However, you are not eligible for a reduction if your level exceeded 0.1%, you injured someone, you refused the test, or you have any drunk driving record since June 30, 2001. We also check, within the deadline, whether the decision can be challenged through an administrative appeal. If you decide to challenge it, Jisan Law also handles the administrative appeal and administrative lawsuit.

Sentencing materials must be verifiable

A letter of apology alone is not enough. What counts are materials that can actually be verified, such as proof that you sold your car or stopped driving, records of alcohol counseling or treatment, and a petition from your family promising that you will not drive again. If you need to drive to make a living, you should support this with a certificate of employment or income records.

If you receive a summary order imposing a fine and feel the amount is too heavy, you can request a formal trial (정식재판) within 7 days of receiving notice (Criminal Procedure Act Article 453). In a formal trial requested by the defendant, the court cannot impose a heavier type of punishment than the summary order, but the fine amount can go up, so think it through before you request one.

Factors that affect the outcome and sentence

Factors that work against you

  • · Fleeing from the checkpoint or obstructing the test

Factors that work in your favor

  • · A short driving distance and understandable circumstances
  • · A settlement with the victim and compensation for the harm

Frequently asked questions

Is it drunk driving if I only moved my car a few meters in a parking lot while waiting for a designated driver?

The Road Traffic Act also punishes drunk driving in places other than roads, so a short distance alone does not clear you. However, why you moved the car, how far and where can be taken into account at sentencing, so keep a record of these together with your designated driver call history.

Is it test refusal if I could not blow properly a few times?

Test refusal applies when a person who there is good reason to believe is drunk does not comply with the test. A few failed attempts alone do not automatically count as refusal; the decision looks at the officer's request and warnings and your attitude at the time as a whole. It is important to write down what happened at the scene in time order.

If I drink more after being stopped, can I dispute my level?

No. That itself is punishable. Drinking more in order to obstruct the test is prohibited under the Road Traffic Act and carries the same statutory penalty as test refusal.

If I have insurance, am I free from criminal punishment after an accident?

For an ordinary accident causing injury through occupational negligence, prosecution is not allowed if you have comprehensive insurance. But if the accident falls under one of the 12 exceptions, such as drunk driving, running a red light or crossing the center line, or if the victim was seriously injured or you left the scene, you can be punished regardless of insurance.
