When driving, how should the side mirrors be positioned?

Positioning the side mirrors to see just the edge of the vehicle is important for optimizing your field of view while driving. This adjustment allows drivers to have a better perspective on the areas immediately surrounding their vehicle, which is vital for safe lane changes and merging maneuvers. When you can see the edge of your vehicle in the side mirrors, it means the mirrors are set up to minimize blind spots and enhance awareness of vehicles or pedestrians that may be in proximity.

This positioning also helps drivers ensure that they don’t only focus on the road directly behind but also extend their view to adjacent lanes. While adjacent lanes are crucial to monitor, it's ideal to have a mirror set in a way that provides a comprehensive view of both the car’s sides and the surrounding traffic.

Adjusting mirrors solely to see the road behind, focus on the rear seats, or only concentrate on adjacent lanes does not promote a comprehensive approach to vehicle safety. Therefore, setting the mirrors to see just the edge of the vehicle strikes the right balance, allowing for a broader and more effective field of vision while driving.
