What is indicated by a regulatory sign?

A regulatory sign indicates rules or laws that must be obeyed by drivers. These signs are essential for maintaining order and safety on the roads. They communicate specific requirements that, if not followed, can result in penalties or accidents. Examples of regulatory signs include stop signs, yield signs, speed limit signs, and no parking signs. Understanding and adhering to these signs is crucial for drivers to ensure not only their own safety but the safety of others on the road.

The other options do not accurately define the purpose of regulatory signs. For instance, signs providing directions or services guide drivers on routes or available amenities, while warning signs alert drivers to potential hazards they may encounter on the road, such as sharp turns or pedestrian crossings. Recreational signs, on the other hand, inform drivers about leisure activities or facilities nearby, which does not pertain to traffic laws or regulations.
