DRIVERS VIEW OF THE ROAD

INFORMATION

‘OFFICIAL’ STICKERS

‘Official’ stickers which are not readily removable – such as vehicle licences, parking and access permits – are only a reason for rejection if they seriously restrict the driver’s view. ‘Official’ stickers should be taken to be any sticker which 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.

OPAQUE EDGING

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.

ADDITIONAL OPAQUE FILMS

Additional opaque films are a reason for rejection whether fitted on the inside or outside of the windscreen.

WIPER BLADES

Wiper blades that park automatically in a position that obscures the view through the windscreen is a reason for rejection.

ADDITIONAL MIRRORS

Additional mirrors are not subject to a Reason for Rejection.

WINDSCREEN

This inspection applies to all vehicles (including those with opening windscreens).

TEMPORARY WINDSCREENS

Temporary windscreens are not intended for everyday use. A temporary windscreen fitted to a vehicle presented for test is to be a reason for rejection.

REPAIRED WINDSCREENS

Repaired windscreens must be inspected to the same test criteria as original 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

Scratches on the windscreen, i.e., light surface scratching, is 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.

WINDSCREEN PROTECTION

Windscreen protection or additional strengthening support 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, also their windscreens and windows may be constructed of either safety glass or safety glazing.

SUNVISORS

Sunvisors fitted to the driver’s 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.

TYPE OF GLASS AND LIGHT TRANSMISSION

ITEM	WINDOWS	TYPE OF GLASS	LIGHT TRANSMISSION
1	Windscreens and other windows wholly or partly on either side of the drivers seat fitted to motor vehicles first used before 1st June 1978 NOTE: This requirement only applies where glass is fitted.	Safety glass, or Specified safety glass, or Specified safety glass (1980)	No requirement
2	Windscreens and other windows wholly or partly on either side of the drivers seat fitted to motor vehicles first used on or after 1st June 1978 but before 1st April 1985	Specified safety glass, or Specified safety glass (1980)	70%
3	Windscreens and other windows wholly or partly on either side of the drivers seat fitted to motor vehicles first used on or after 1st April 1985	Specified safety glass (1980) (These side windows may be safety glazing if the vehicle has been issued with a Department’s Approval	Windscreens 75% (70% if the vehicle has been issued with a Department’s Approval Certificate)
		Certificate)	All other windows 70%
4	All other windows	Safety glazing, or Specified safety glass, or Specified safety glass (1980)	No requirement

To help identify the type of glass fitted see note on acceptable markings.

The visual transmission for light is very difficult to assess, the colour of tinting can be very deceiving and therefore it is only to be regarded as a reason for rejection if it is very obvious that the light transmission is less than the legal requirement. A Light Transmission Meter may be used where necessary to assist examiners in their assessment.

Using a glass sample, compare with the window and assess the light transmission.

TAXI SIGNS

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 driver’s view.

GROOVED WINDSCREENS

Grooves in the windscreens which are designed specifically to clean the wiper blades are not a reason for rejection unless they seriously impair the driver’s view of the road.

MASCOTS

Mascots and other external mountings forward of the windscreen are not part of the test in respect of drivers view but are included as part of the general condition of the vehicle.

ORIGINAL DESIGN

Original vehicle design characteristics are to be accepted.

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 examiner may, at their discretion, ask the customer to remove the items prior to the inspection.

METHOD OF INSPECTION

Sit in the driver’s seat and check that there is a reasonable view of the road through the windscreen and windows wholly or partly on either side of the driver’s seat.

Check presence and security of all windscreens, side, roof or rear windows, or internal screens or partitions.

Visually check the condition of all windscreens, internal screens and partitions, side, rear, roof and door windows for cracks, discolouration, surface damage and correct material.

Check for presence, security and condition of guard rails or barriers at windows, internal screens or partitions.

When checking the windscreen refer to the diagram below.

Zone "A" is 290 mm wide, in the swept area of the screen and centred on the centre of the steering wheel.

Zone "B" is the remainder of the swept area.

Damage or discoloration will be a reason for failure if it impairs the driver's view of the road.

Examiners should have regard for the two separate "zones" when assessing damage or discoloration. A greater amount of damage or discoloration could be accepted in zone "B" than in zone "A".
