What is the primary purpose of regulatory signs?

The primary purpose of regulatory signs is to establish traffic laws. These signs convey important rules that drivers must follow to ensure safety and compliance with the law on the road. For example, they dictate actions such as when to stop, yield, or proceed with caution, as well as set forth specific requirements like speed limits. Understanding and adhering to these regulations is crucial for maintaining order and preventing accidents.

While many regulatory signs indicate specific actions (such as stop signs or yield signs), the broader function they serve is to define and establish the legal framework that governs driver behavior. This is essential in providing consistent expectations for all road users, contributing significantly to overall traffic management and safety. Other choices, while related to aspects of driving, do not encapsulate the comprehensive role that regulatory signs play in laws governing vehicle operation.
