Which type of signs inform you of possible hazards ahead?

Warning signs are designed to alert drivers to potential hazards or changes in road conditions ahead, allowing them to take caution or necessary action. These signs typically have a yellow background with black symbols or text, signaling various conditions such as curves, intersections, pedestrian crossings, or construction areas.

Understanding the specific purpose of the other sign types helps clarify why warning signs are the correct answer. Regulatory signs establish laws or regulations that drivers must follow, such as speed limits or stop signs, focusing more on performance than on inherent hazards. Information signs provide guidance or helpful details, like distances to destinations or rest area locations, and directional signs help with navigation but are not primarily concerned with warning about potential dangers. Thus, warning signs are the key indicators that prepare drivers for hazards that may require increased attention or reduced speed on the road.
