What is true about changing lanes in an intersection?

Changing lanes in an intersection is considered potentially dangerous for several reasons, which is why this is the correct answer. Intersections often have a high concentration of vehicles, pedestrians, and cyclists, all of whom add to the complexity and risk of maneuvers such as lane changes. When changing lanes, drivers may have limited visibility due to the presence of other vehicles and may not be able to see pedestrians crossing or other road users.

Additionally, the very nature of intersections involves multiple pathways for vehicles, which can lead to unexpected situations, such as a car turning unexpectedly or a vehicle moving into the space you plan to enter. This unpredictability signifies that lane changes require careful consideration and awareness of the surrounding environment, making it risky.

In contrast, the other options suggest scenarios that do not accurately reflect the general risks and legalities associated with lane changes in intersections. For instance, it is not legally required to change lanes in intersections, and while it may be safe under specific circumstances, it is not universally safe to assume that lane changes can be done without risk. The presence of HOV lanes also doesn't restrict the ability to change lanes; rather, it adds further complexity to navigation through intersections.
