If you plan to drive yourself in Sri Lanka, you will need an International Driving License preferably with an endorsement from the Automobile Association of Ceylon (AA). If you plan on getting an endorsement from the AA, make sure you avoid making your visit on a national holiday. If you are serious about driving around by yourself, remember to get comprehensive insurance and be wary of bus drivers. Don't forget to get GPS with Sri Lankan maps. But you may need to stop and ask for directions once in a while.
