Final answer:
Drivers aged 16-17 are usually allowed to have only one non-family member in the vehicle unless they are with a parent or guardian, although the exact number can vary by local laws.
Step-by-step explanation:
The question pertains to the driving laws for young drivers particularly those aged between 16-17. These laws commonly restrict the number of passengers that can legally be in a vehicle with a new driver. The exact number of non-family members allowed can vary by state or region, so it's important to consult local driving regulations. However, a typical rule might be that drivers between the ages of 16-17 shall have no more than one non-family member in the vehicle unless accompanied by a parent or guardian.
