Successfully convert an Indian driving license to Malaysian?

Section 28 of the Road Transport Act (APJ) 1987, states that "a driving license issued under the corresponding provisions of any law in force in any State which is a party to a treaty to which Malaysia is also a party and purporting to recognize domestic driving licenses issued by the contracting countries shall, so long as the license remains in force in that State, be deemed to be a driving license granted under this Part. ""

Pursuant to Section 28 of APJ 1987, as mentioned above, the holder of a foreign country's driving license can drive in this country as long as the foreign domestic driving license is still valid, and is accompanied by a translation in English or Malay (where the license is in a language other than English or Malay), which is confirmed by the embassy of the country of origin in Malaysia, or by the authority issuing the driving license concerned.
[b]In this regard, a foreign citizen is not required to hold a Malaysian driver's license to drive in Malaysia.[/b]
In addition, foreign nationals who want to drive in this country also have the option to use an International Driving Permit (International Driving Permit-IDP) issued by the country concerned before entering Malaysia.
