What it means

This is a minor defect: the car passes its MOT and the defect is recorded. A minor defect has no significant effect on safety or the environment. The car passes its MOT and the defect is recorded on the certificate. It should be repaired as soon as possible.

The windscreen, wipers, washers and mirrors are checked so the driver has a clear view. Damage in the area the wipers sweep matters most.

The MOT inspection manual describes it (section 3.3) as:

Obligatory mirror or device slightly damaged or loose

The DVSA codes counted on this page: the manual item and the defect text as DVSA records them. The heading above joins the two, as a certificate does; the tester also adds the position, such as nearside front.
