3 sub-groups of Regulatory Signs

Answer: B — Prohibitive Signs; Directional Signs; Priority Signs

Regulatory signs shape how you must behave on the road. They’re split into three main kinds that together cover what you can’t do, what you must do, and how you should move through intersections. Prohibitive signs tell you what actions are forbidden, like no entry or no left turn. They directly restrict certain movements to prevent dangerous or disruptive behavior. Priority signs establish who goes first at intersections or how you should proceed on a road, such as give way, stop, or road with priority. They set the order of traffic to prevent conflicts and crashes. Directional signs guide your navigation by showing routes or directions you should follow, helping you reach destinations and stay in the correct lanes. They regulate movement by directing you toward permitted paths. These three groups together form the regulatory category because each one imposes binding rules on driver behavior. Other sign types, like warning signs, alert to hazards, or informational signs, simply provide guidance, but do not impose the same mandatory rules.
