Which section of the driver handbook focuses on rules for changing lanes safely?

The section titled "Lane Changes" is dedicated to providing drivers with the necessary rules and guidelines for executing safe lane changes. This section covers critical aspects such as checking mirrors, using turn signals to communicate intentions, and ensuring that there is enough space to merge safely into the new lane. The emphasis here is on the techniques and procedures that reduce the risk of collisions during lane changes, making it an essential part of safe driving practices.

While the other options relate to important driving topics—like "Parking" which outlines procedures for safely parking vehicles, "Passing" which focuses on overtaking vehicles on the road, and "Signaling" that emphasizes the importance of indicating intentions to other drivers—they do not specifically address the nuances of changing lanes. Therefore, the "Lane Changes" section is the most relevant for understanding how to change lanes safely.
