Driver's license
The minimum driving age varies between 16 and 18 years of age in different States and Territories. After the minimum age, a graduated licensing scheme operates, with state variations.
Learner's permit
In order for a minor to receive a learner's permit, sometimes called an "instructional permit", states typically require that the minor have at least 6 practice hours before getting the permit and signed permission from a parent or guardian. In the state of New Hampshire, a permit is not given but the young driver may begin to drive with a parent or guardian, or an adult 25 years of age, at the age of 15 and a half.
