How should you adjust your mirror for optimal visibility?

To achieve optimal visibility, it is essential to ensure that your mirrors allow you to see the road behind and the sides of your vehicle. This comprehensive view is crucial for maintaining awareness of your surroundings, particularly in relation to other vehicles and potential hazards. Adjusting your mirrors in this manner helps to minimize blind spots, enhancing overall safety while driving. By being able to see both directly behind you and alongside your vehicle, you can make more informed decisions when changing lanes, merging, or navigating through traffic.

The other options do not adequately address the primary goal of mirror adjustment, which is to maximize visibility for safe driving. Setting the mirror to only show the road behind restricts your peripheral vision and could lead to dangerous blind spots. Positioning it merely to reduce glare from headlights or adjusting it solely for personal comfort overlooks the critical aspect of situational awareness needed for safe driving.
