Final answer:
The licensed driver accompanying a permit holder under 18 should be an adult over a certain age with a valid license; others may ride in the back.
Step-by-step explanation:
When under 18 and driving with an instruction permit, the question concerns the legal requirements for the accompanying licensed driver. Typically, the licensed driver must be a parent, guardian, driving instructor, or someone of that caliber, who is at least 21 years old and has a valid driver's license. Also, it is generally allowed for other passengers to ride in the back seat, as long as the driving conditions are safe and the driver is not distracted.
