What are the exceptions of a curfew for a driver with a graduated driver license?

Answer: D — parent or legal guardian with a valid A, B, C, or D license occupying the front seat

For a driver with a graduated driver license in Arizona, one of the exceptions to the curfew restrictions is having a parent or legal guardian with a valid A, B, C, or D license occupying the front seat. This exception allows for a young driver to drive outside of the curfew hours as long as an experienced driver is present in the vehicle to provide guidance and supervision. This exception is important for ensuring that the young driver gains valuable driving experience in a safe and controlled manner. Therefore, option D is the correct answer. The other options are not relevant to the exceptions of a curfew for a driver with a graduated driver license. Driving alone (Option A), having friends in the car (Option B), and playing loud music (Option C) are not exceptions to the curfew restrictions and should be avoided by drivers with a graduated driver license.
