This depends on your country of origin. Those from Europe, Australia and the US do not have to take the test. Instead you must go to the Roads and Transport Authority with your existing licence, passport and resident permit. There you will be required to take an eye test before being issued with your UAE license. Prior to receiving your residence permit you may drive a rental vehicle using your license from your home country. A comprehensive list of who is exempt from retaking the test is available from the Dubai Roads and Transport Authority.
