Traffic warning signs in work zones are usually what color?

Traffic warning signs in work zones are typically orange because the color orange is universally recognized as a signal for caution and alertness regarding road work or construction activities. This color is chosen specifically to draw attention and indicate that drivers should be prepared for changes in road conditions, potential hazards, or reduced speed limits as they approach the work area.

In contrast, other colors have different meanings in the context of road signage. For example, yellow is often used for general warning signs indicating caution but does not specifically denote work zones. Red is reserved for stop signs and signals, signifying that drivers must come to a halt. Green is used for directional guidance and signs indicating where to go or how far to a certain destination, not for caution or warning. Hence, the use of orange is crucial in work zones to ensure that motorists are aware of and can respond appropriately to temporary changes in the roadway.
