Windscreen Inspection Zone
Zone 'A is:
. in the swept area of the Windscreen
. 290mm wide
. centred on the centre of the steering
'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 Policy
Sunvisors fitted to the driver's side, which cannot be stowed
in the 'offscreen' 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
Where items are present in the driver’s 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 Item 1 of the Inspection
Original vehicle design characteristics are to be accepted.
Additional Opaque Films
Additional opaque films are subject to reason for rejection 1
whether fitted on the inside or outside of fhe 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, eg 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
rhey seriously restrict the drivers view.
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 if 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.
This inspection applies to vehicles in Classes 3, 4 & 7 (including those with opening windscreens).
Note: For Class 5 vehicles see Section 6.9
