If you have your learners permit and are over 18 how long do you need to wait before getting your license?
In Arizona, if you are over the age of 18, you don't have to abide by the 6 month waiting period with your permit. You are immediately eligible to get your full license at anytime as long as you can pass the driving test. The 6 month permit hold only applies to anyone under the age of 18.
