What should be the primary focus when adjusting your mirrors?

The primary focus when adjusting your mirrors should be on adjacent vehicles. Properly adjusted mirrors are crucial for maximizing your visibility of other vehicles around you, particularly those that may be in your blind spots. Ensuring that you can see the lanes alongside and behind your vehicle helps to prevent accidents and allows for safer lane changes and merges.

In contrast, while road signs are important for navigation and obeying traffic laws, they are not directly influenced by the adjustment of mirrors. Similarly, nearby pedestrians are vital to consider when driving, but they are best monitored directly through looking out of your windows and not through mirrors. Personal comfort is also a valid concern, as comfortable positioning can aid in better visibility, but it should not take precedence over ensuring that you have a clear view of your surroundings. The safety implications of adjusting mirrors primarily revolve around awareness of adjacent vehicles, making this the correct focus.
