Which of the following is NOT a common sign at a roundabout?

The presence of common signs at a roundabout is primarily to manage traffic flow and ensure safety for both drivers and pedestrians. The signs such as “Roundabout” and “Yield” are specifically designed to inform drivers of the need to reduce speed and give way to traffic already on the roundabout. Additionally, “Keep Left” is a crucial directional sign ensuring that vehicles navigate the roundabout correctly, adhering to the local driving conventions.

While pedestrian crossings are vital in many areas for protecting pedestrians, they are typically not situated directly within the roundabout itself. Instead, pedestrian crossings are usually marked well before the roundabout entry or just after the exit points to keep pedestrian and vehicle traffic separate, thus enhancing safety around the roundabout, where vehicle speeds may vary and can pose risks to pedestrians. Hence, spotting a “Pedestrian Crossing” sign directly at the roundabout is uncommon compared to other essential traffic signs in that environment.
