Car MOT Manual 2012 onwards

Drivers View of the Road - 8.3 Windscreen

Windscreen Inspection Zones

Zone A is: • in the swept area of the windscreen
• 290mm wide
• centred on the centre of the steering wheel.

Official stickers that are not readily removable, such as vehicle licences, parking and access permits, are only a reason for rejection if they seriously restrict the drivers view. Official stickers should be taken to be any sticker that is used in connection with road enforcement, security or crime prevention matters.

These include: Disabled Persons Badges-permits, Parking Permits, Licences and Vehicle Anti-Theft Scheme stickers issued by a Police Authority.

Sunvisors fitted to the drivers side, which cannot be stowed in the off screen position and which drop down obstructing the view through the swept area of the windscreen are a Reason for Rejection. A similar defect on the passenger side sunvisor is not a Reason for Rejection.

This inspection applies to vehicles in Classes 3, 4 7 including those with opening windscreens

Note: For Class 5 vehicles see Section 6.9
Method of Inspection
Where items are present in the drivers view -such as a sat nav, air freshener etc- that would justify a Reason for Rejection, the tester may, at their discretion, remove the items prior to the inspection.

This fact should be noted on an Advisory Notice. Opaque edging on a windscreen -usually black, particularly at the lower edge- found on some modern vehicles is not to be regarded as part of the windscreen when assessing the drivers view through the windscreen within 8.3 item1 of the Inspection Manual.

Original vehicle design characteristics are to be accepted.

Additional opaque films are subject to Reason for Rejection 1 whether fitted on the inside or outside of the windscreen.

Additional mirrors and tinting films are not subject to Reason for Rejection 1.

Windscreen protection or additional strengthening supports fitted to vehicles which have a security role, e.g. bullion vehicles, Post Office vehicles etc intended to aid security, are not to be considered a Reason for Rejection when assessing obstructions to vision.

Taxi signs displayed in the front windscreen of Hackney Carriage vehicles of the type used to indicate when the vehicle is for hire -usually by being illuminated- are only a Reason for Rejection if they seriously restrict the drivers view.

1. Whilst sitting in the drivers seat AND, referring TO the diagram ON the previous page, examine the driver s VIEW OF the road through the swept area OF the windscreen.
Reason for Rejection
Mascots and other external mountings forward of the windscreen are not part of the test.

Wiper blades that park automatically in a position that obscures the view through the windscreen are subject to Reason for Rejection 1

Repaired windscreens must be inspected to the same test criteria as unrepaired windscreens. Repairs must be judged solely on the basis of whether they interfere with vision.

An invisible or barely detectable repair, finished flush with the surrounding glass, does not count as damage even i f it exceeds the limit on damage allowed in the test.

If these criteria are met, the position and size of repairs is not relevant for the purposes of the test.

Scratches on the windscreen, i.e. light surface scratching, are not to be considered as damage. However, an area of concentrated scratching such as caused by the prolonged use of a defective wiper blade which obscures vision is to be considered a Reason for Rejection if it meets the fail criteria.

1. In Zone A:
a. damage not contained within a 10mmdiameter circle, or
b. a windscreen sticker or other obstructionencroaching more than 10mm
c. a combination of minor damage areas which seriously restricts the drivers view
In the remainder of the swept area:d. damage not contained within a 40mmdiameter circle, or
e. a windscreen sticker or other obstructionencroaching more than 40mm
f. a temporary windscreen fitted.
Note: All the items listed in the information column should be taken into account before rejecting a vehicle.
