Final answer:
For 16 or 17 year old permit holders, passenger restrictions usually limit passengers to immediate family or a supervising adult. These restrictions vary by jurisdiction and are part of graduated licensing laws to improve road safety.
Step-by-step explanation:
For the entire period of time a 16 or 17 year old permit holder has a permit, the only passengers that can be in the vehicle are typically immediate family members, or an adult over a certain age with a valid driver's license, depending on the laws of the specific jurisdiction or state.
In many states, there are graduated licensing laws that place restrictions on young drivers to enhance their safety and the safety of others on the road.
These restrictions often include passenger limitations, such as allowing only family members or no passengers at all for a certain period, or requiring a supervising adult driver in the vehicle.
After a certain time period or upon reaching the age of 18, these restrictions may be lifted. It is critical that permit holders and their parents or guardians familiarize themselves with the specific traffic laws and restrictions in their area to ensure compliance and safety on the road.
