What does the sign indicating 'Traffic queues likely' signify?

The sign indicating 'Traffic queues likely' serves as a warning to drivers that they may encounter traffic congestion ahead. It prepares them for potential delays, prompting them to adjust their driving behavior accordingly. This could involve reducing speed, remaining alert, and increasing the following distance from the vehicle in front. Being aware of such possibilities allows drivers to stay calm and responsive rather than reacting suddenly when they find themselves in stop-and-go traffic. This awareness can contribute to safer driving conditions overall.

The other choices suggest different driving actions unrelated to congestion. Changes in speed limits, immediate stops, or yielding to pedestrians are specific scenarios that may not necessarily relate to the warning of potential traffic queues. Understanding the implications of 'Traffic queues likely' emphasizes the importance of smooth and cautious driving in response to anticipated delays.
