Frequently Asked Questions

  • If you are between the ages of 16 and 18 or are under 22 years old and receiving special education services through the Individualized Education Program (IEP), you qualify for the Graduated Driver License (GDL) program. This program allows you to obtain a learner’s permit. After completing 12 months of the GDL program, if your sponsor hasn't withdrawn their endorsement and your driving record is clear, your permit will convert to a class D license. 
  • If you are 18 years or older and choose not to participate in the GDL program, no sponsor is required, but you'll need to undergo an eye, knowledge, and road skills examination at the DMV to obtain your driver's license.
Apply in person at any Division of Motor Vehicles office in Wilmington, New Castle, Dover, or Georgetown. Verify where the nearest Delaware DMV office is and check its business hours before going.
