Step-by-step explanation:
Brown traffic signs serve the purpose of warning about potential hazards or road conditions. These signs are typically used to alert drivers to specific dangers on the road, such as sharp curves, slippery roads, or animal crossings. They are designed to catch the attention of drivers and inform them to proceed with caution.
For example, a brown traffic sign that shows a picture of a deer crossing the road indicates that drivers should be prepared for deer in that area and adjust their speed accordingly. Another example is a brown traffic sign with a picture of a truck tipping over, which warns drivers of a steep hill or sharp turn ahead.
