To obtain a class D driver's license in Alabama, teens must follow the three steps of the Graduated Driver License (GDL) system. Here are the age requirements:
  • For a learner's permit, you must be at least 15 years old.
  • For a restricted license, you must be 16 years old or older.
  • For an unrestricted or regular license, you must be at least 17 years old. However, individuals aged 17 must hold a restricted license for at least six months before applying for a regular license. If you are 18 years old or older, you may apply for a driver’s license immediately (the road skills exam is required).

Individuals who are 18 or older, those aged 17 or older with valid licenses for six months or more, individuals 16 or older who are married and the head of the household, and emancipated individuals are exempt from the GDL program.

After passing the required examination, new drivers receive a driver's license with the 'Y' restriction. This allows them to drive accompanied by a driver aged 21 or older or a certified driving instructor seated beside them. For drivers who are 16 years old or 17 with a license of less than 6 months, specific restrictions apply:
  • No more than 1 non-family passenger, excluding parents, guardians, or supervising licensed drivers at least 21 years old.
  • No driving between 12 midnight and 6 a.m., unless accompanied by a parent or legal guardian or under certain exceptions like work, school events, religious events, or emergencies.
  • It is unlawful to use handheld communication devices while driving.

Upon passing the road test, a regular license is issued, and the 'Y' restriction is removed.


In Alabama, the learner's license is valid for four years, with the option to renew it once. This waiting period ensures you have ample time to gain valuable driving experience and feel confident before the road exam.
