What do all road signs with a yellow background, such as R10, indicate?

Road signs with a yellow background serve a specific purpose in traffic management and road safety. These signs are typically used to indicate temporary situations; for example, they might highlight roadwork, detours, or other conditions that require immediate attention from drivers. The bright yellow color is specifically chosen for its high visibility, ensuring that the message is conveyed effectively and attracts the attention of motorists, especially in conditions where they need to alter their driving behavior or be cautious.

The misconception that these signs indicate permanent situations or guidance is common, but the distinctive use of yellow is primarily associated with temporary road conditions that may change frequently. Understanding this helps drivers recognize the importance of staying alert when approaching such signs, ensuring safety for themselves and others on the road.
