What does a yellow diamond-shaped sign typically indicate?

  1. Regulatory information

  2. No parking zone

  3. Warning or caution

  4. Speed limit

The correct answer is: Warning or caution

A yellow diamond-shaped sign typically indicates warning or caution. These signs are used to alert drivers to potential hazards or changes in road conditions ahead. For instance, they may signal things like merging traffic, sharp curves, or pedestrian crossings. The color yellow and the diamond shape are both standardized by traffic regulations to convey that drivers should proceed with extra caution and be prepared for unexpected situations. Recognizing and responding appropriately to these signs is crucial for maintaining safety on the road, as they help prevent accidents by proactively informing drivers of dangers they may encounter ahead.
