Roadway signs and signals communicate three essential things that guide safe driving: they regulate traffic rules you must follow, warn you about hazards ahead so you can adjust your behavior, and provide directions that tell you where to go or which lane to be in. Stopping at a red light, yielding at merging lanes, or obeying a speed limit all come from these signs and signals. Warnings—like a curve ahead or a school zone—give you time to slow down and proceed with caution. Directional signs and lane signals help you navigate and stay in the correct path on your route. Because signs and signals convey legal requirements and safety guidance, obeying them is a fundamental part of driving responsibly.

The other options don’t fit. Signs aren’t decorative and do carry safety information; they serve far more than just indicating speed limits; and they don’t replace traffic laws—they reinforce and enforce them by telling you what you must do or avoid on the road.
