Final answer:
Within the first year of acquiring a license or until the driver attains the age of 18, whichever occurs earlier, restrictions are imposed on the maximum number of passengers allowed.
Step-by-step explanation:
As per the provided information, during the initial year of obtaining a license or until the driver reaches the age of 18, whichever comes first, there is a restriction on the number of passengers allowed.
Specifically, only one individual under the age of twenty is permitted, unless that additional passenger qualifies as a sibling, stepsibling, child, or stepchild of the driver.
Following this initial period, a different set of passenger limitations comes into effect.
The maximum number of passengers is then restricted to one in the front seat, and the number of occupants in the backseat is contingent upon the availability of safety belts.
This phased approach to passenger restrictions aims to promote safe driving practices for new or young drivers, gradually easing limitations as they gain experience and maturity behind the wheel.
