iirc 15 years and 6 months to get your learner’s permit, and you get your driver’s license if you’ve done enough driving stuff within a year, so the youngest you can be and get your lisence is 16 years and 6 months

it’s different in certain states, but in mine, you have to be 14 and a half to get your learners permit (I can already get mine, I’m just not taking the class yet) and you can get your license at 15 if I remember correctly.
