Which color combination is used for temporary warning signs?

Temporary warning signs are crucial for alerting drivers to potential hazards or changes in road conditions. The correct color combination for these signs is orange with black lettering. This choice is standardized because orange is highly noticeable and often associated with construction and maintenance areas, ensuring that drivers can quickly identify them as indicators of warning in situations where caution is required.

The use of black lettering on the orange background enhances visibility and readability, allowing important information to stand out clearly. This combination is particularly effective in conveying essential warnings about detours, road work, or other temporary changes to driving conditions.

Alternative color combinations, such as yellow with black lettering, green with white lettering, and red with white lettering, serve different purposes. Yellow is typically associated with general warning signs, green usually indicates permitted actions or directions, and red is reserved for signs requiring drivers to stop or yield. Understanding these distinctions helps ensure that drivers respond appropriately to road signage, enhancing overall safety on the roads.
