5-1 Glazing

Reasons for rejection

Glazing condition

1. A piece of glazing is not mechanically sound, or is not securely affixed to the vehicle.

2. A windscreen or front side window is so dirty or obstructed that the driver’s vision is unreasonably impaired.

3. A windscreen has damage that prevents the wiper blades from working properly.

4. A windscreen has scratches, discolouration or other defects that unreasonably impair the driver’s vision or compromise the strength of the windscreen.

5. A modification:

a) unreasonably impairs driver’s vision through the windscreen or a front side window, or

b) adversely affects the strength or mechanical performance of the glazing.

Glazing performance

6. The overall visible light transmittance (VLT) (Note 2) of a windscreen is less than 70%.

7. The overall VLT of a front side window is less than 35%.

8. Glazing has a mirrored effect sufficient to dazzle other road users.

Permitted modifications

9. A modification that affects glazing is not within the limits in Table 5-1-1.

Note 1 Definitions

Windscreen means all glazing extending across the front of the vehicle that is not parallel to the vehicle’s centreline but does not include a wind deflector. No fitting of overlays or stickers are permitted to the windscreen except those previously mentioned.

Overlay means a transparent, translucent or opaque self-adhesive or clinging film that is applied to large areas, or the whole, of a piece of glazing, including anti-glare band overlays and stoneguard overlays.

Sticker means a self-adhesive or clinging film, with or without print on it, that is applied for purposes such as advertising, identification, information, decoration or legal reasons.

Anti-glare band overlay means a tinted overlay that is transparent and that is applied along the top edge of the windscreen for the purpose of reducing glare from the sun.

Damage includes any unrepaired damage and attempted visible repairs.

Note 2

Visible light transmittance (VLT) is the proportion of visible light that passes through glazing, measured perpendicular to the glazing. Overall VLT is the VLT of the glazing together with any overlays.

Table 5-1-1. Permitted modifications

Fitting of or modification to:

Modification permitted provided that:

– a current parking permit or other document issued by the local authority

– learner L-plates (in sticker format) provided the driver’s vision is not unreasonably affected.

  • the overlay does not extend below the bottom edge of the vehicle’s OE sun visors when they are folded down as far as possible towards the windscreen, and

Radio antennae

  • antennae are wholly within 100mm of any edge.

Front side windows

Transparent overlays

  • the overall visible light transmittance (VLT) is not reduced to below 35%.

Stickers

  • stickers are wholly within 100mm of the bottom edge, or 50mm of any other edge, unless required or permitted by legislation.
  • manufacturer’s operating instructions may be applied to or incorporated in the glazing.

Radio antennae

  • antennae are wholly within 100mm of any edge.

Rear and rear side windows (behind the driver’s seat)

Overlays and other modifications

  • the vehicle is equipped on both sides with external rear-view mirrors.

Stickers

  • stickers may be applied anywhere on the glazing, but if not wholly within 100mm of any edge, the vehicle must be equipped on both sides with external rear-view mirrors.

Radio antennae

  • in-service requirements for condition and performance are met.

Fitting of or modification to:

Modification always permitted:

Monsoon shields

  • in-service requirements for condition and performance must be met.
