I got mine about a month before my 19th birthday.
I did take my exam when I was 16, but the unwritten rule in our town was that ALL girls were failed on their first test. The examiner was so mean and nasty to me trying to distract me to get me to fail by messing up (he eventually just marked fail on my sheet, even though I'd done nothing wrong), that I couldn't bear to go back for a long time.
But overriding that was the fact that there was no point in my getting a license since I had no car to drive nor any money to pay for insurance. My parents had made it quite clear that they were not going to allow me to drive their cars and would not pay my insurance and since they would not allow me to work, I had no way to earn money for a car let alone gas/insurance. So in that situation, what was the point of getting a license?
I did know how to drive, both automatic and stick. But didn't get my license until I went away to college.
