What do orange traffic signs typically warn drivers about?

1. Speed limit changes

2. Potential obstacles in the road due to construction

3. Upcoming traffic signals

4. Wildlife crossing

The correct answer is: Potential obstacles in the road due to construction

Orange traffic signs are specifically used to alert drivers to construction zones or work areas where potential obstacles may be present. These signs are crucial for ensuring safety on the road, as they signal to drivers that they need to be cautious and prepared for changes in road conditions, such as reduced lanes, detours, or workers in the area. The use of orange is universally recognized as a warning in temporary situations, distinguishing it from other sign colors that convey different types of information. While speed limit changes, upcoming traffic signals, and wildlife crossings are important road signs, they are designated by other colors such as white for speed limits, yellow for traffic signals, and specific wildlife signs.
