Explanation:

Road signs, signals, and pavement markings are traffic control tools. Their primary function is to guide drivers, alert them to hazards (e.g., stop signs, warning signs), and promote safe navigation. The correct option aligns with this purpose, while others are incorrect (they do not increase speed or allow unsafe lane changes).
