What type of sign typically indicates construction zones?

Construction zones are typically indicated by an orange diamond sign. This design is used specifically to alert drivers to construction work, road repairs, or maintenance activities that may affect traffic. The bright orange color is highly visible and immediately conveys a warning, which is essential for ensuring the safety of both workers and motorists in these areas. The diamond shape further emphasizes that the sign is a warning, drawing the driver’s attention to approach with caution.

In contrast, other sign types serve different purposes. Square green signs generally provide information related to guidance, such as directional signs or mile markers, while yellow triangle signs indicate slow-moving vehicles or cautionary warnings. Red circle signs are used to indicate prohibitions, such as stop signs or no entry, and are not related to construction zones.
