Step-by-step explanation:
Graduated Driver Licensing (GDL) Requirements
For permit holders under the Graduated Driver Licensing (GDL) program, the amount of required logged hours of night driving may vary from state to state. However, a common requirement is for students to log a certain number of night driving hours as part of their practice before they can qualify for a driver's license. In many states, it is typical to require 10 hours of night driving. This requirement helps ensure that new drivers have experience in different driving conditions before becoming fully licensed. It is essential to check the specific requirements of your state's GDL program as they can differ.
