What are Warning Traffic Signs?

Warning traffic signs alert drivers to potential hazards and road conditions ahead that require heightened caution and attention. Typically depicted as red and white diamonds or other distinctive shapes, these signs prepare drivers to adjust speed, awareness, or direction in response to dangers such as pedestrian crossings, sharp curves, or slippery surfaces.

Short answer

Warning traffic signs are red and white diamonds that alert drivers to hazards like pedestrian crossings, sharp curves, slippery roads, or schools. They advise caution but do not command—drivers must exercise judgment and adjust accordingly.
