Philadelphia Drivers License Practice Test

The correct approach to a roundabout involves slowing down and yielding to the traffic that is already circulating within the roundabout. This is crucial because roundabouts are designed to promote a continuous flow of traffic while minimizing the potential for accidents. When you slow down, you can better assess the situation inside the roundabout and determine when it is safe to enter. Yielding to the vehicles already in the roundabout ensures that you do not disrupt the flow of traffic or create hazardous conditions.

Entering a roundabout too quickly or without yielding can lead to collisions, as you might force other drivers to brake or swerve to avoid you. Similarly, coming to a complete stop before entering is not typically necessary unless there is a stop sign, traffic signal, or some other exceptional condition. Merging without altering speed can also prove dangerous, as it does not consider the movement of traffic in the roundabout, which requires careful timing and adjustment of speed to merge safely. Hence, slowing down and yielding promotes safe driving practices in such traffic situations.
