Which side mirror adjustment is considered best?

The best side mirror adjustment features a position that maximizes the driver's field of vision while minimizing blind spots. When a mirror is positioned correctly, it should show the side of the vehicle in the inner edge of the mirror, which allows the driver to have a better view of any vehicles coming up alongside.

Adjusting the mirror to this optimal position ensures that the driver can see vehicles approaching from behind and helps in making safer lane changes. The correct setting also enhances the overall awareness of the environment around the vehicle, contributing to safer driving practices.

In comparison, other mirror settings may either allow significant blind spots or require the driver to turn their head excessively to check for nearby vehicles, which can distract from focusing on the road ahead. Effective mirror positioning is crucial for safe driving, and understanding how adjustments impact visibility is key for drivers to maintain situational awareness on the road.
