The flow chart illustrates the process of obtaining a driving license in the United State

As can be seen that, there are 3 main parts in this process, beginning with going to the driving license center and ending with getting the driving license

First of all, it is necessary to go to the driving license center to register by filling in the form. Then, an eyesight test is given, and no license can be given to those who fail the test. In contrast, those who pass this exam must then pay fees to have the written exam

After paying the required fees, the applicants will take the written exam. The result of this test will determine the next step and they will have two chances to retake the written exam if they fail the written exam. Once the written exam is successfully passed, a practical road exam will be carried out immediately. It is obligatory to pass both exams to get the driving license. However, those who fail the road exam or fail the written exam again must pay fees before being allowed to reattempt both written exam and road exam.
