Final answer:
A special GDL permit allows new or young drivers to operate a vehicle under certain conditions to gain experience before obtaining a full license. These conditions vary by location and might include supervised driving or restrictions on driving times and passenger numbers.
Step-by-step explanation:
A special GDL permit (Graduated Driver's License) often allows a new or young driver to drive with certain restrictions before they obtain a full driver's license. The specifics of what a GDL permit allows can vary by jurisdiction, but generally, it might permit driving with an adult supervisor, driving during daylight hours, or driving with a limited number of passengers. Such permits are designed to ensure that new drivers gain experience under less risky conditions before becoming fully licensed.
In the context given, it seems that Peter is frustrated by another driver's adherence to traffic laws, which is a separate issue from the allowances of a GDL permit. Regardless of the permit status, all drivers are expected to follow traffic laws and drive safely, respecting the rights of other road users, including those who choose to drive at or below the speed limit.
