What colour are the road signs for primary non-motorway routes?

Primary non-motorway route signs are green. This color is used to indicate the routes that are part of the main road network, providing information for drivers on secondary roads or primary routes that are not designated as motorways. The green color is easily recognizable and is used to help direct drivers through both urban and rural areas.

In contrast, other colors serve different purposes: red is typically used for prohibitive signs or warnings, yellow may indicate temporary road signs or cautionary information, and blue is often reserved for informational signs such as those indicating services or directions to motels and rest areas. The use of green for primary non-motorway routes provides clarity and consistency, aiding navigation for both local and visiting drivers.
