With a properly adjusted mirror, what can you see?

A properly adjusted mirror allows you to see part of the lane behind you and beside you. This positioning is crucial for safe riding, as it provides a broader field of view, allowing you to be more aware of the vehicles approaching from behind and the side, which is essential for making safe maneuvers and lane changes.

When the mirror is adjusted correctly, it should show enough of the road to help you gauge the distance of other vehicles as well as their speed relative to your own. This visibility helps in assessing the traffic situation and improves your overall situational awareness while riding. Hence, seeing part of the lane behind and beside you is key to maintaining safety on the road.
