To drive a car in Korea, people need a driver's license or an international driver's license from their own country.
International driver's licenses are valid for a period of one year. Those who have driver's licenses from their own countries need to submit an original copy of the license, a certified translation of the license, certification from the embassy, their passport, Alien Registration Card, certification of immigration and three colored photos to the driver's license examination office to be exempted from some of the tests to acquire a domestic driver's license. It's difficult for those staying less than 90 days to get a Korean driver's license.
Testing procedures for a driver's license
Traffic safety education takes place in the traffic safety education center at driver's license test sites or at driver training institutions.
Available languages : English, Chinese and Vietnamese
Required items when taking the written test: Application form (with three photos), a marker for computer paper and an ID card
Necessary Documents : Application form, Resident Registration Card (or other document proving your identity)
Multicultural family support centers and police stations can help foreigners or married immigrants to acquire a driver's license for free. For detailed information, contact your local Multicultural Family Support Center or police station or driver's license examination office. (Call 1577-1120)
