What should you yield to when approaching a roundabout?

Answer: C — Pedestrians and bicyclists

When approaching a roundabout, yielding to pedestrians and bicyclists is crucial for ensuring safety. Roundabouts are designed to keep traffic flowing smoothly while reducing the chances of high-speed collisions, but they also prioritize the safety of all road users. In a roundabout, pedestrians may be crossing at designated crosswalks, and it's important for drivers to yield to them to allow safe passage. Similarly, bicyclists often use the roundabout and share the road with motor vehicles. Yielding to both pedestrians and bicyclists demonstrates responsible driving and helps prevent accidents, ensuring that everyone can navigate the area safely and efficiently. Other vehicles do not receive priority over pedestrians and bicyclists; it's vital to be aware of them while navigating through a roundabout. Additionally, emergency vehicles should always be given a clear path, but this often pertains to situations where the vehicles are responding to incidents rather than routine roundabout navigation. Lastly, traffic signs provide guidance but are not considered entities that you yield to in the same manner as pedestrians and bicyclists. Therefore, yielding to pedestrians and bicyclists is a fundamental rule when approaching and navigating roundabouts.
