What does a yellow diamond-shaped sign indicate?

• A. End of speed zone
• B. Road closed ahead
• C. Caution or warning about road conditions or hazards
• D. No parking allowed

Answer: (C)

A yellow diamond-shaped sign is universally recognized as a caution or warning about potential road conditions or hazards up ahead. These signs are used to alert drivers to various situations that may require increased attention or slower speeds. For example, they may indicate curves in the road, pedestrian crossings, livestock crossings, or changes in road surface conditions. The use of yellow signifies that the driver should take note of the warning and prepare for any necessary adjustments to their driving behavior. This is crucial for maintaining safety on the roads, as it helps prevent accidents that may occur due to unexpected hazards. In contrast, signs indicating the end of a speed zone or no parking are typically of different shapes or colors — often rectangular or blue — while a sign indicating a road closure would likely use a different visual strategy (such as barriers or more starkly defined shapes) to convey that significant changes are ahead.
