Conversion of Foreign Driving Licence
If you hold a foreign driving licence and intend to remain in Singapore for less than twelve months, you are not required to convert your foreign driving licence to a Singapore driving licence. You may drive in Singapore with a valid foreign driving licence. However, if your licence is not in English, in addition to a valid foreign driving licence, you are required to have an International Driving Permit. If an International Driving Permit is not available, an official translation of your driving licence in English is required.
If you are holding an Employment Pass/Dependent Pass/Student Pass/or Work Permit and are likely to reside in Singapore for more than twelve months and you wish to continue to drive in Singapore, then you are required to convert your foreign diving licence to a Singapore driving licence before the end of your twelve months stay.
To convert to a Singapore driving licence, you are required to pass the Basic Theory Test (BTT) which will familarise you with traffic rules and Singapore's Highway Code pertaining to traffic related issues peculiar to Singapore. A Singapore Permanent Resident (PR) who wishes to drive in Singapore is required to convert his foreign driving licence after becoming a PR.
Application for conversion of foreign driving licence for Singaporeans and PR are not normally granted unless:
they have stayed in the foreign country continuously for at least six months after the date of first issue of their foreign driving licence
the foreign driving licence at the time of application for conversion must have been issued for a period of six months or more
for PRs, the driving licence was obtained before the applicant became a PR.
