Final answer:
Newly licensed drivers under 18 are commonly restricted to having one passenger under 18 during the first six months of driving. This limit is part of Graduated Driver Licensing programs designed to reduce risks for new drivers.
Step-by-step explanation:
The regulations regarding the number of passengers under the age of 18 that a newly licensed driver may have during the first six months vary by state. However, it is common for states to have restrictions to limit distractions for new drivers. Often, a newly licensed driver under age 18 is permitted to have only one passenger under the age of 18, unless the passengers are family members or unless accompanied by a parent or guardian. These laws are part of Graduated Driver Licensing (GDL) programs, which are designed to provide new drivers with the opportunity to gain driving experience under lower-risk conditions.
