Final answer:
A motorist must enroll in a Probationary Driver Program during their two-year probationary period after receiving a permit if they commit a traffic offense or as required by law.
Step-by-step explanation:
The question pertains to a scenario in which a motorist is required to enroll in a Probationary Driver Program. While the provided information does not give specific details about the probationary period for new drivers, general knowledge suggests that during a two-year probationary period after receiving a special learner or an examination permit, a motorist must enroll in such a program if they commit a traffic offense or are otherwise required to by law. Much like the trial or probationary period described for new employees in a labor market, the program serves as an additional educational and correctional measure to address any infractions and to encourage safe driving habits.
