What does an orange sign indicate?

An orange sign is specifically designated to indicate that there is road work or construction ahead. This color is used universally in traffic signage to alert drivers to temporary changes in the road conditions, including construction zones, maintenance work, or other activities that may affect the flow of traffic.

By using orange for these signs, authorities aim to increase visibility and draw attention to situations where drivers may need to proceed with caution. This is crucial because construction zones often require adjustments to speed and lane use to ensure the safety of both drivers and workers.

The other options, while related to traffic management, are indicated by different colored signs. For example, traffic regulation signs usually are white or red, signaling laws that drivers must obey. Speed limit changes are typically marked with white signs containing black text, and school zones are indicated by yellow signs to heighten awareness. Each color serves a distinct purpose to convey specific messages to drivers effectively.
