What action should you take when approaching a roundabout?

When approaching a roundabout, the proper action is to yield to the traffic that is already in the roundabout. This is crucial for maintaining the flow of traffic and preventing potential collisions, as vehicles inside the roundabout have the right-of-way. Understanding the flow of a roundabout is essential for safe navigation, and yielding helps ensure that you can merge smoothly into the circulating traffic.

It's important to recognize that simply driving straight through without stopping is not safe or advisable, as it disregards the established right-of-way rules. Additionally, while signaling before entering is good practice, specifically yielding to the traffic already in the roundabout is the most critical action you should take to ensure safety and compliance with traffic laws. These principles reflect common traffic rules designed to facilitate the orderly movement of vehicles at roundabouts.
