Motorbike licensing is a grey area in Cambodia. Practically speaking, the majority of locals do not have a license, however new legislation has been passed and is slowly being enforced. Not having a local license with you is rarely an issue in Cambodia, however it can be an issue for travel insurance companies. Some companies require local licenses, others require home licenses, and others will accept an international license. Please check the fine print of your insurance to make sure of their policy regarding engine size limitations and riding documentation.
