Mirrors allow you to observe what is happening around your car. They are your most important visual driving aid, and are vital for safe driving. Their purpose is to let you know what is happening behind, which is just as important as knowing what is happening in front.

When driving, you must use your mirrors frequently, and responding safely to what you see in them.

Interior Mirror

Also known as the rear view mirror, This is usually a mirror made with flat glass which gives a true picture of anything behind you. The image reflected in such mirrors isn't distorted, which makes it easier to judge the speed and distance of following traffic.

Most car mirrors have an anti-dazzle lever. This is for use at night so that you are not blinded by the glare of headlights from vehicles behind.

As with all car mirrors, only adjust the interior mirror when the car is stationary and you are seated in your normal driving position. Hold the mirror at the edges to avoid finger marks. Adjust the mirror so that you get the best possible view through the back window without having to move your head. You should be able to frame the whole of the rear window in the interior mirror, but, if you can't, make sure you can see the top right-hand side of the rear window.  

Exterior Mirror

These are convex mirrors, which are made using curved glass. Convex mirrors give a wider field of vision, however, they make judging the speed and position of following traffic more difficult. Vehicles will appear smaller and further away than they actually are.

Adjust the exterior mirrors so that you can get the best rear view with minimal head movements. You should be able to see a small strip of the side of the car, and the horizon should appear about in the middle of the mirror.

Nearside and Offside

The nearside mirror is the one nearest the kerb, on the left-hand side of the car. The offside mirror is the one on the right-hand side

Using Your Mirrors

Regular use of your mirrors is an essential part of safe driving. You need to be aware of what is happening around you at all times.

When using your mirrors you should be asking yourself what's behind you, how near they are to you, what speed they are travelling at and what their intentions are. You must have enough time to decide, which makes early use of the mirrors essential.

Which mirrors you use will depend on the situation and manoeuvre you intend to carry out. Normally, you should use the interior mirror first followed by the exterior mirrors.

Before carrying out any manoeuvre always check your mirrors. This includes:

Approaching Hazards
