What shape and color are work zone signs?

Work zone signs are specifically designed to alert drivers to changes in road conditions, temporary closures, or other hazards that could impact safety. These signs are diamond-shaped and colored orange. The diamond shape is crucial because it indicates warnings, while the bright orange color is highly visible and draws attention, ensuring that drivers can notice them in advance. This combination of shape and color helps to effectively communicate the need for caution in driving through construction or maintenance areas.

The other shapes and colors mentioned, such as triangular red signs which typically indicate yield or danger, rectangular white signs that convey regulatory information, and round yellow signs which are used for railroad warnings, do not serve the same purpose as work zone signs. Thus, the correct identification of work zone signs as diamond and orange is essential for ensuring safety on the roads.
