Can you be 13 years old to drive and then get a permit and then get a licence when you are 15 years old?

In some states, such as Montana, you can get your permit at 14 1/5 and license at 15. My Grandpmother had a "Farm License" in Colorado. At age 12 she could operate farm equipment, including registered vehicles, from ranch to ranch. Very limited use and that was 70 years ago.
