Which statement best describes the function of regulatory signs?

• A. Directions and information about routes and destinations.
• B. Rules and laws that must be obeyed.
• C. Warnings of hazards ahead.
• D. Construction notices.

Answer: (B)

Regulatory signs encode the rules and laws that must be obeyed on the road. They tell you what actions you must take or must not take, such as stopping at a stop sign, adhering to a speed limit, or prohibiting certain maneuvers. Because these signs reflect legal requirements, not following them can lead to penalties or fines, regardless of personal preference. This makes regulatory signs distinct from other types: guide or informational signs show routes and destinations, warning signs alert you to hazards, and construction notices warn about work zones.
