Which sign tells drivers to slow down?

• A. Bypass
• B. HOV Lane
• C. Slow Down
• D. Change of traffic Lanes

Answer: (C)

Signs that give a direct instruction use verbs that tell you exactly what to do. A sign that says “Slow Down” is telling you to reduce your speed to a safer level for the upcoming road conditions, such as a sharp curve, pedestrian area, construction zone, or a narrowing road. It’s a clear directive aimed at improving safety.

The other signs serve different purposes. A bypass sign points you to an alternate route around an area. An HOV Lane sign designates lanes reserved for vehicles with multiple occupants, not a speed instruction. A change of traffic lanes sign warns that lane lines will shift or that you may need to merge, which is about lane position, not speed.

So the sign that tells drivers to slow down is the one that literally instructs you to reduce your speed.
