Fees
Original Class D instruction permit: $20. Renewal permit: $10. If you obtain your license before the permit expires, an additional license fee may not be required; check your transaction with SOS. Official source
Documents
For ages 15–17, check enrollment in an approved driver-education course. SOS requires the permit application and proper identification; the application must include the certified instructor signature for the driver-education route. Official source
Booking a visit
Use the SOS DMV Facility Finder to check the selected facility and its appointment instructions. Make sure the service is an instruction permit, not a renewal or road test. Official source
