In short
A US licensing system that adds driving privileges in stages (learner's permit → restricted licence → full).
A graduated driver licence (GDL) is a US licensing system used in most states for new drivers under 18. It grants privileges in stages: a learner's permit, then a provisional or intermediate licence with restrictions (no driving at night, no teen passengers), then a full unrestricted licence.
The exact stages and restrictions vary by state.
