Final answer:
The 'hours of operation' and 'passenger' restrictions do not apply to SLP and Examination Permit holders over 21. Permit restrictions can legally vary based on age as they are designed for public safety and responsible behavior regulation.
Step-by-step explanation:
According to the Student Learner's Permit (SLP) and Examination Permit restrictions, the hours of operation and passenger restrictions do not apply to permit holders over 21. The distinction in permit restrictions is one of the legal tools that governmental bodies use to regulate behavior and improve safety, relying on age as a criterion for differentiating permitted activities. This form of legal discrimination is deemed acceptable in several aspects, such as the purchasing of alcohol or tobacco, and the issuing of driver's licenses, as these laws are intended to protect certain populations, ensure public safety, or encourage responsible behavior.
