If a driver signals properly before changing lanes, how is that action rated?

The rating of "Good" for a driver who properly signals before changing lanes reflects adherence to a fundamental traffic safety practice. Proper signaling is critical in promoting communication between drivers on the road, allowing others to anticipate movements and adjust accordingly. This action demonstrates that the driver is aware of their surroundings and is taking the necessary steps to ensure safety for themselves and others. Signaling before lane changes is a key component of responsible driving behavior, supporting the idea that the driver is following best practices. Thus, being rated as "Good" highlights the importance of such actions in contributing to safer driving conditions overall.
