Final answer:
The holder of a GDL Special Learner Permit must fulfill all of the mentioned requirements, including passing a knowledge test, supervised driving, and a road test, to get a probationary license. These are forms of legal discrimination designed to ensure public safety by strictly regulating who is eligible to drive.
Step-by-step explanation:
The holder of a validated GDL Special Learner Permit must meet several requirements before obtaining a probationary license. These requirements typically include Option 4: All of the above, which encompasses passing a written knowledge test, completing a minimum of 6 months of supervised driving, and passing a road test. In most states, these criteria are aimed at ensuring the permit holder has both the theoretical knowledge of driving laws and practical skills necessary for safe driving.
Moreover, these licensing requirements are examples of legal discrimination based on age and abilities, which are intended to promote public safety. While the term 'discrimination' often has negative connotations, in this context, it refers to laws that appropriately treat certain individuals differently to protect the well-being of the general public. Such measures, including age requirements for smoking and drinking, or educational prerequisites for college admission, are deemed lawful and serve specific societal functions.
