Hawkwell driving schools : DSA Approved Driving Instructor:   adjusting your mirrors

Adjusting your mirrors correctly:

Your interior mirror should be adjusted so that you have a fairly central view of the road behind. Sometimes a bias slightly to the right improves the perspective, and gives a better view of potentially overtaking traffic. In the photo the centre of the rear screen (silver sticker)
lines-up with the centre of the night dip lever on the mirror itself.

Your door mirrors should be adjusted (as shown) so that you can see a little of the side of the car. This is so that you know where anything you see in the door mirror is relative to you. The horizon in the door mirror should be about two thirds of the way up.

Each side of the car there are blind areas, areas that you cannot see when you are looking forwards, and that you can't see when you look in the mirrors. A car about to pull away on your right, or from a driveway, can easily be hidden in your blindspot.
