Motorcycle license can be obtained by adult UAE citizens/residents after training from an authorized driving school in Dubai. If you are 18-21 year of age, you can apply for a probationary license.
There are a few things you need to do is get your eye's tested by a qualified optician or by your riding school.
Once you've done a couple of small tests with your riding school. There are then 2 main tests you have to take. The first is the "Signal test" or also know as the "theory test." This test is around AED 80. The next test is the Road test which is self explanatory, general on road riding, this is about AED 80 as well. Your riding school should handle all the paperwork during this process for you.
Providing you pass both these test you will then get your license.
