How do you set the right side mirror correctly?

The correct method for setting the right side mirror involves leaning to the right so that your head is positioned below the rearview mirror. This approach allows you to adjust the mirror so that you have the best view of the lane adjacent to your vehicle, reducing blind spots. By positioning yourself this way, you ensure that your line of sight through the mirror provides a clear perspective of any vehicles or obstacles that may be approaching from the right side.

Standing outside the vehicle might give a view of the mirror's position but does not account for the driver's perspective while seated inside. Sitting upright and adjusting the mirror to eye level doesn't specifically address the angle needed for optimal visibility on the right side. Keeping your head raised above the window can hinder your ability to see the necessary perspective to adjust the mirror for safe driving. The technique of leaning to the right is specifically beneficial for achieving a proper view of your surroundings while driving.
