If you are a foreigner and want to drive in Singapore, you need a Qualified Foreign Driving License and an IDP.
For ASEAN (Association of South East Asian Nation) member countries, you only need a valid driving licence issued by the relevant driving licence Authority in your country.
If your country is not a member of the ASEAN, you need an additional permit, which is the International Driving Permit (IDP) issued by your country's Automobile Association (AAP).
How long can I drive using my Foreign Driving License and IDP?
You can drive in Singapore within 12 months using those license and permit. After that, you have to convert it to a Singapore License by passing the Basic Theory Test (BTT).
