I just obtained an international driving license for the purpose of driving in a foreign country for this upcoming vacation. Obtaining one is not a hassle. While Qatar Automobiles & Touring Club (QATC) is the sole authority in Qatar to issue International Driving License, you can obtain the same from any major travel/car rental agents in Qatar (I read that it can be obtained at the following*: Al Muftah Rent A Car, Ali bin Ali Travel, Sulaiman Travel, Aamal Travel). *Note: Not an exhaustive list.
I obtained mine through Aamal Travel & Tourism in City Center. No specific reason except it is conveniently located at City Center (don’t tell me about the parking though:) ). I submitted a copy of Qatar driving license, two photographs (any color), and QR100. The license is ready the next day. Some said that it should have been ready within an hour.
The international driving license is valid for one year from the issuing date. the license contains information on personal identity, type of vehicle for which the license is issued, and driving license number.
