What Does VLT Mean?

VLT stands for Visible Light Transmittance. This measurement refers to the amount of natural light that is able to pass through the window once a particular window tinting film has been applied to the glass of your car. VLT can be measured roadside by using a VLT card, but this is an approximate measure at best. A true and correct reading requires the use of an electronic VLT meter. If you are unsure about whether the current film on your car complies with the guidelines, or have been issued an infringement notice as a result of a roadside inspection and would like an accurate reading, Ultra Tint has a number of correctly calibrated VLT meters.


Glazing (Windscreen and Windows)

Transparent material (e.g. glass, acrylic) used in a windscreen, window or interior partition of a motor vehicle

manufactured after June 1953 must have the characteristics required by any of the following standards: • Australian and New Zealand Standard S/NZS 2080 Safety Glass for

Land Vehicles

• British Standard BS AU178: Road Vehicle Safety Glass

• Japanese Industrial Standard JIS R 3211 Safety Glazing Materials for

Road Vehicles

• American National Standard ANSI Z26.1 Safety Code for Safety

Glazing Materials for Glazing Motor Vehicles Operating on Land


• United Nations Economic Commission for Europe (UNECE)

Regulation 43/00 Uniform Provisions Concerning Approval of Safety Glazing and Glazing Materials

• New Zealand Standard (NZS) 5443.

Window Tinting

No material or other object is to be located on the windscreen or windows which will interfere with the driver’s vision.

Film which has a reflectance of more than 10 per cent must not be used on any windscreen or window.


Tinting may be applied to the upper portion of a windscreen of a motor vehicle. The tinting must not extend lower than a

horizontal line connecting the uppermost points of the arcs swept by the vehicle manufacturer’s original wiper blades or

the upper 10 per cent of the windscreen, whichever is the lesser. The tinting may be of any shade.

Windscreens which have tinting incorporated within the glazing (not applied tint) are permitted subject to the screen

having an optical transmission of not less than 75 per cent for a motor vehicle built after 1971 and 70 per cent for any other vehicle.

Vehicles with Non-tinted Glass

Automotive tinting material which has a light transmittance factor of not less than 35 per cent (T35) may be applied to any non-tinted side or rear window.

Vehicles with Factory-Tinted Glass

Most new vehicles are fitted with tinted glass (tinted film incorporated within the glazing). In some cases it may be difficult

to determine if the glass is actually tinted. To check if the glass is tinted, hold a piece of white paper on the opposite side

of the glass. If it has a slight grey, green or brown colour when viewed through the glass, the glass is tinted.

Special grades of film (including clear film) may be applied to factory tinted windows. When these films are applied to tinted glass, the combination of tints must still allow a minimum light transmittance of 35 per cent.

Please note: The Australian Design Rules (ADRs) now allow privacy glass to be fitted to a vehicle rearwards of the driver’s vision. Privacy glass has no minimum light transmittance and is often darker than T35 tint. Privacy glass incorporates tinted film within the glazing and is not defined as an applied tint. All applied tint must meet the above requirements and not the requirements set out for privacy glass in the ADRs.
