What is a key benefit of using your mirrors correctly?

Using mirrors correctly is crucial for increasing awareness of surrounding vehicles, which is the main benefit highlighted in the question. When a driver actively monitors their mirrors, they gain a comprehensive understanding of what is happening around them. This includes being aware of blind spots, other vehicles in adjacent lanes, pedestrians, and potential hazards. Enhanced situational awareness contributes significantly to safe driving practices, allowing for timely reactions to changes in the traffic environment, such as other drivers changing lanes or approaching from behind.

The other options, while they may have some ramifications related to mirror use, do not directly address the primary purpose of mirror usage in driving. For example, improved fuel efficiency or reduced tire wear are influenced by overall driving habits and vehicle maintenance rather than the act of using mirrors. Similarly, while driving comfort can be improved through good visibility and reduced stress from constant lane change worries, it is the heightened awareness that stands out as the most critical benefit of proper mirror use.
