The key function of a regulatory sign is to indicate rules regarding traffic and driver behavior. These signs are designed to inform drivers of laws and regulations that must be followed to ensure safety and proper traffic flow. For example, regulatory signs include stop signs, yield signs, and speed limit signs, all of which dictate specific actions that drivers must take or avoid. By adhering to these rules, drivers contribute to a safer driving environment for themselves and others on the road. The other options highlight functions that do not pertain to regulatory signs. Information about scenic routes or vehicle service stations falls under informational signage, which is entirely different from regulatory signs focusing on traffic law compliance. Recommended speeds are typically conveyed through advisory signs, which suggest safe speeds but do not impose enforceable rules like regulatory signs do.
