Which of the following is an example of rule-based regulation?

• A. Drive according to the weather conditions
• B. No smoking in public areas
• C. Do not drive over 100km/h on the highway
• D. Make decisions based on ethical theories

Answer: (C)

Rule-based regulation is characterized by specific, clear guidelines or rules that individuals must follow. The answer "Do not drive over 100km/h on the highway" embodies this concept because it establishes a precise limit that is legally enforceable and does not allow for personal interpretation or discretion. This type of regulation is straightforward, relying on a specific standard that defines acceptable behavior—in this case, the maximum speed allowed on highways.

In contrast, the other options involve a range of interpretive decision-making. For instance, driving according to the weather conditions requires subjective judgment based on varying circumstances, such as rain, fog, or snow, making it less about a fixed rule and more about personal assessment. No smoking in public areas, while a regulation, can involve interpretation regarding what constitutes "public areas," leading to potential ambiguity. Finally, making decisions based on ethical theories is deeply subjective and relies on personal beliefs and values rather than clear-cut regulations. Thus, option C stands out as the only choice that represents a distinct rule-based regulation.
