To drive a motor vehicle in Korea, you need a driver's license. To get a driver's license, you must pass the driver's license exam.
If you hold an international driver's permit issued by a country with which Korea has a road and transport agreement, you can drive on that permit for up to one year from the date of your arrival in Korea, without acquiring a Korean driver's license.
A holder of a foreign driver's license can apply for a Korean driver's license by confirming the validity of his or her foreign driver's license with documents provided by the embassy of his or her home country, and then must pass an aptitude test and/or a driving knowledge test.
All of the other legal information you need about how to acquire and maintain a driver's license, as well as how your license can be cancelled or suspended in the event of a traffic infringement, is provided below.
