How should you navigate a roundabout?

Navigating a roundabout correctly is vital for maintaining safety and ensuring the smooth flow of traffic. Yielding to traffic already in the roundabout before entering is essential because it allows you to assess the flow of vehicles and merge safely. This method reduces the risk of accidents and prevents abrupt stops or further complications when entering the roundabout.

When you yield to traffic in the roundabout, you allow vehicles that are already circulating to continue without disruption. This practice leads to better traffic flow and can minimize congestion associated with stops. Once there is a gap in traffic, you can safely enter the roundabout.

Other options suggested do not align with best practices for safely navigating a roundabout. Driving straight through without yielding could lead to collisions, as you would be entering the traffic already in the roundabout without appropriate caution. Always signaling left when entering might confuse other drivers, as signaling should generally indicate your intention to change lanes or turn rather than entering a roundabout. Lastly, stopping before entering the roundabout could disrupt the flow of traffic and create hazardous situations for both yourself and others.
