What Happens After a DUI in Korea? (Drunk Driving Laws Explained)

Short Answer

If you are caught driving under the influence (DUI) in Korea, you may face criminal charges, administrative penalties on your driver’s license, and possible fines or imprisonment.
The outcome depends on your blood alcohol level and the specific circumstances of the case.

---

Is DUI a Crime in Korea?

Yes. Driving under the influence (commonly referred to as “drunk driving”) is a criminal offense under Korean law.

In general, a person is considered legally intoxicated if their blood alcohol concentration (BAC) is 0.03% or higher.
DUI laws are strictly enforced across Korea, including in major cities such as Seoul and Busan.

How Blood Alcohol Level Affects Penalties

Penalties vary depending on the BAC level and the facts of the case.

In practice:

• Lower BAC levels may result in license suspension and criminal penalties (such as fines)
• Higher BAC levels may lead to license revocation and more serious criminal consequences

For example, BAC levels of 0.08% or higher are commonly treated as grounds for license revocation in practice, although specific outcomes depend on applicable regulations and administrative standards.

Because the exact thresholds and consequences are governed by detailed regulations, outcomes may vary depending on the circumstances and applicable guidelines.

Refusal to Take a Breath Test

Refusing to take a breathalyzer test is treated as a separate criminal offense under Korean law.

However, whether refusal is established depends on the overall circumstances, including whether the individual clearly demonstrated an intention not to comply with the test.
Authorities will assess this based on the full sequence of events, rather than a single incomplete attempt.

What Happens Immediately After Being Caught?

If you are stopped for suspected DUI in Korea, the process typically includes:

Breath Alcohol Test
Police will conduct a breath test.
In practice, procedures may include measures to ensure accuracy (such as clearing residual alcohol in the mouth), and in some cases, a blood test may be conducted if necessary.

Investigation
You may be asked to provide a statement at the police station.

Release or Further Action
DUI cases are often handled without detention, as Korean criminal procedure generally follows the principle of non-custodial investigation.

However, detention may be considered if there are concerns such as:

• Risk of flight
• Risk of evidence destruction
• Serious circumstances (e.g., accidents or repeat offenses)

Criminal and Administrative Consequences

Depending on the case, consequences may include:

• Criminal penalties, such as fines or imprisonment
• Administrative sanctions, including suspension or revocation of a driver’s license

If the DUI results in injury or death, significantly more severe penalties may apply.

Additional Considerations for Foreigners

Foreign nationals may face additional consequences depending on the outcome of the case.

• Certain criminal outcomes, particularly imprisonment or more serious offenses, may lead to immigration consequences under Korean law
• In some cases, even a fine-based conviction may affect visa status or future stay, depending on immigration authorities’ decisions

Because immigration consequences are assessed on a case-by-case basis, early legal advice is important.

---

Important Rights During Investigation

During a DUI investigation in Korea:

• You have the right to remain silent
• You have the right to consult with a lawyer

In practice, if language barriers exist, interpretation may be provided depending on the circumstances.

---

Practical Steps if You Are Charged with DUI in Korea

If you are involved in a DUI case:

• Avoid making unnecessary statements without legal advice
• Carefully review any written statements before signing
• Seek legal counsel as early as possible
• Ensure you understand the process, especially if language is a barrier

In cities like Busan, where DUI enforcement is active, early legal assistance can significantly affect the outcome of your case.

Conclusion

DUI (drunk driving) in Korea is treated as a serious offense, even at relatively low blood alcohol levels.

Because both criminal and administrative consequences may arise—and additional immigration risks may apply to foreign nationals—understanding the process and responding appropriately from the outset is essential.
