Conversion of Graduated or Under 21 License
When you turn 18, you may continue to use your Class G graduated driver license. However, you will be eligible to obtain a replacement (duplicate) license reflecting a Class D operator status that still retains the special vertical orientation that indicates you are under 21.
When you turn 21, you may continue to use your driver license or identification card with the special vertical orientation. However, you are eligible to obtain a replacement (duplicate) license with the regular horizontal orientation without the under-21 designation. See the Application tab of the Driver License Information section.
Note: Fees apply for a replacement license.
