What should you do when approaching a roundabout?

When approaching a roundabout, it is important to yield to traffic that is already within the roundabout. This is crucial because vehicles in the roundabout have the right-of-way, allowing for a smooth and safe flow of traffic. Yielding ensures that you do not disrupt the movement of vehicles that are already navigating through the roundabout, which can prevent accidents and enhance overall traffic efficiency.

The design of roundabouts fosters a circular flow that reduces the likelihood of head-on collisions, and adhering to the principle of yielding before entering is vital to maintaining this safe environment. Properly yielding also gives you the opportunity to assess the situation and enter the roundabout only when it is safe to do so, contributing to a more organized traffic system.

Options suggesting to speed up or stop without a valid reason would not only disrupt the traffic flow within the roundabout but could also lead to dangerous situations. Similarly, changing lanes without signaling fails to communicate your intentions to other drivers, increasing the risk of collisions. Therefore, yielding to existing traffic is the appropriate and safest action when approaching a roundabout.
