- Graduated Driver Licensing (GDL)
- Related: Instruction Permit, Initial License (Probationary License), Rookie Driver Decal
Illinois' three-stage licensing system for new drivers: instruction permit, initial license, and full license. Each stage adds privileges only after the driver meets age, holding-period, practice-hour, and clean-record requirements.
