What is the correct response when approaching a roundabout?

When approaching a roundabout, the correct response is to yield to traffic already in the roundabout. This is crucial because roundabouts are designed to facilitate continuous flow of traffic, reducing stop-and-go situations that can lead to congestion and crashes. By yielding to vehicles that are already circulating, you ensure that you merge safely and give priority to those vehicles, which in turn helps maintain the efficiency and safety of the roundabout.

It's important to recognize that entering a roundabout without yielding could lead to dangerous situations, as it ignores the right-of-way rules and could cause collisions with circulating vehicles. Stopping before entering the roundabout is unnecessary if there is no oncoming traffic since the design of roundabouts allows for a seamless flow. Lastly, accelerating to enter quickly is not advisable as it undermines safety and the yielding requirement, potentially causing conflicts with vehicles that have the right of way. Understanding the yielding rule is essential for navigating roundabouts safely and effectively.
