What document must be shown to a supervisor while driving with a Class 7 permit?

The learner's permit is the essential document that must be shown to a supervisor while driving with a Class 7 permit. This permit signifies that the driver is authorized to practice driving under the supervision of a qualified individual who meets the legal requirements. Having this valid permit demonstrates that the driver is still in the learning stage and complies with the regulations set forth for novice drivers.

While the registration of the vehicle and an insurance certificate might be necessary for driving legally on public roads, they are not specifically required to be shown to a supervisor during the learning process. A valid ID card is also usually not relevant in this context, as the learner's permit itself serves as identification of the driver's legal status to practice driving.
