DUI Laws in Korea: The Basics

South Korea has stringent DUI laws, with zero tolerance for driving under the influence.

The legal blood alcohol concentration (BAC) limit for drivers is 0.03%, which is lower than in many Western countries. A foreign driver who is unfamiliar with this standard may want to discuss the applicable rules with a lawyer in South Korea.

To put this into perspective, just one or two standard drinks could put a driver over the legal limit, depending on their body weight and other factors .

Driving while under the influence of drugs is also a punishable offense.

This includes not just alcohol, but prescription drugs or any substances that impair a person’s ability to drive safely.

Where alcohol, prescription medication, or another substance is involved, a lawyer in South Korea may review the circumstances surrounding the driving and the evidence collected by the authorities.

CHECK POINT
DUI Standards in Korea
Blood Alcohol Concentration
In Korea, the legal standard for drunk driving is 0.03% blood alcohol concentration, and depending on an individual's physical condition and circumstances, even a small amount of alcohol consumption may exceed the legal limit.
Drug-Impaired Driving
Substances that may affect driving ability, including prescription medications, may also be subject to criminal penalties.
02

Penalties for DUI in Korea

The consequences of a DUI conviction can be severe.

For expats, these penalties can be particularly impactful, affecting their visa status, residency, and even future entry into South Korea. This additional immigration impact is one reason a foreign national may consult a lawyer in South Korea after a DUI incident.

RESULT
DUI Penalties
For a BAC of 0.03% to 0.08%
A first-time offense could lead to fines of up to 2 million KRW (about $1,500 USD), a driving suspension for up to a year, or even imprisonment for up to a year.
For a BAC above 0.08%
The penalties increase significantly, with fines up to 5 million KRW ($3,700 USD) and a potential prison sentence of up to 3 years.
Refusal to take a breathalyzer test
If you refuse to take the breath test, you may face heavier fines or even jail time, in addition to a driving suspension.

The law is also particularly strict on repeat offenders, with increased penalties for those caught DUI multiple times.

When the potential penalty includes a fine, license suspension, or imprisonment, a lawyer in South Korea may review the BAC level, prior record, and other circumstances relevant to the case.

03

Impact on Your Visa Status

As an expat, a DUI conviction in South Korea can affect your visa status, including:

01. Visa Denial or Revocation
Certain criminal offenses, including DUI, can lead to the cancellation of your visa or denial of future visa applications.
02. Fines and Imprisonment
As noted, DUI convictions carry heavy fines and the potential for imprisonment, which could directly impact your ability to work and reside in Korea.

If you are on a work visa or planning to apply for a visa extension, a DUI offense could jeopardize your legal status in South Korea. A lawyer in South Korea may therefore need to consider both the criminal case and the possible immigration consequences.

i
Legal consultation is important
It’s critical to consult a legal expert, like Majung Law Firm, to understand your options.

For an expat facing both criminal and visa concerns, speaking with a lawyer in South Korea can be important when determining what legal issues need to be addressed together.

04

The Role of the Police

Korean police are vigilant about DUI enforcement, particularly in urban areas.

Sobriety checkpoints are common, and there are also high-tech measures in place to detect DUI offenders.

Police are empowered to administer breathalyzer tests on the spot, and refusal to comply can lead to more severe legal consequences. Where there is a dispute concerning the breath test or police procedure, a lawyer in South Korea may review the circumstances.

Even if you’re not involved in a traffic accident, you may still be stopped for random checks, and you’ll be expected to comply.

Make sure you carry identification and your driver’s license (an international driver’s permit or Korean license) at all times.

05

What to Do if You're Arrested for DUI

If you’re arrested for DUI in South Korea, follow these important steps

RESPONSE
What to Do After a DUI Arrest
01. Cooperate with Authorities
Never resist arrest or fail to comply with breathalyzer requests. Resisting can lead to harsher penalties.
02. Contact a Lawyer
The moment you’re arrested, request legal representation. Majung Law Firm is available to assist expats in navigating the legal system and minimizing the potential consequences.
03. Do Not Leave the Scene
In South Korea, leaving the scene of an accident or DUI checkpoint can significantly increase the severity of penalties.
04. Consider the Language Barrier
If you don’t speak Korean, ensure that an interpreter is available, especially when interacting with law enforcement.

Requesting a lawyer in South Korea promptly may be particularly important where the foreign national must respond to police questioning, understand the evidence, and consider possible visa consequences at the same time.

If language is a concern, a lawyer in South Korea working with interpreter support may help the client understand the investigation and communicate throughout the case.

06

Preventing DUI in Korea: Tips for Expats

The best way to avoid a DUI conviction is simply not to drive after drinking.

Here are some tips:

01. Use Public Transportation
Korea’s public transport system is extensive and reliable. Trains, buses, and taxis are all excellent alternatives to driving.
02. Designated Drivers
If you must drive, arrange for a designated driver. This is a safe option and helps avoid the legal and personal risks of DUI.
03. Stay Sober or Use Ride-Sharing Apps
Services like KakaoTaxi and Tada make it easy to get around without needing to drive.

Preventing the incident is always preferable to dealing with a criminal investigation later, even where a lawyer in South Korea is available to provide legal assistance after a DUI allegation.
