What is the proper way for a commercial driver to navigate a roundabout?

Navigating a roundabout properly is crucial for the safety of both the commercial driver and other road users. Yielding to traffic already in the roundabout ensures that the vehicle joins the circulating flow without disrupting it. This practice helps prevent accidents and maintains a smooth traffic flow. Maintaining a safe speed is also important, as it allows the driver to make necessary adjustments while navigating the curves of the roundabout, which can be particularly important for larger commercial vehicles that require more space to maneuver.

Additionally, signaling when exiting the roundabout provides clear communication to other drivers regarding the driver's intentions. This is essential for predictable driving behavior and contributes to overall road safety. By doing so, other drivers can anticipate the movement, enabling a safer exit from the roundabout.

The importance of yielding, maintaining speed, and signaling encapsulates the safe and courteous driving behavior expected in such traffic situations, which is why this approach is considered the correct method for navigating roundabouts.
