How many types of licenses available to people 17 years old or younger?

In most U.S. states, individuals 17 years old or younger typically have access to two main types of licenses: a learner's permit and a full provisional or intermediate license. A learner's permit allows them to practice driving under the supervision of a licensed adult. Once they meet specific requirements, they can obtain a provisional license, which may have certain restrictions, such as limits on night driving or the number of passengers. The exact types and requirements can vary by state.
