The best practice when approaching a roundabout is to yield to traffic already in the roundabout. This is important because vehicles within the roundabout have the right of way. Yielding allows for a smooth flow of traffic and minimizes disruptions and accidents. As you approach the roundabout, you should look for gaps in the circulating traffic so you can enter safely when it's clear.

Stopping before entering the roundabout may not be necessary and could disrupt the flow of traffic, especially if it is not required due to the presence of stop signs or lights. Accelerating to merge into traffic can lead to unsafe situations, as it may not give you adequate time to gauge the speed of vehicles in the roundabout. Using your horn to alert other drivers is generally discouraged, as it can cause confusion and does not replace the need for proper signaling and yielding. Therefore, yielding to the traffic already in the roundabout is the most effective strategy for ensuring safety and efficiency in these scenarios.
