If you fail you will need retake a driving test. The number of times that you can retake a driving test depends on the jurisdiction or state that you live in. Each state, through their department or division of motor vehicles determine the administration of your driver’s test. This includes the number of times that the test can be taken before you pass it.
Most all states will allow you retake a driving test an unlimited number of times if you fail it. What may differ is the amount of time that you have to wait between retake attempts. This can be 24 hours or 10 days, up to 30 days or even 6 months. A state may also impose a classroom training or study component for a driver that fails their driving test as a way to ensure that core competency is met.
