Window Tint Laws in NSW (2026): Legal VLT Limits

New South Wales sets a minimum Visible Light Transmission (VLT) for each window. VLT is the percentage of light that passes through the glass and film together. A higher number means a lighter, clearer window. A lower number means darker.

The important thing to understand is that the front of the car is treated more strictly than the back. You get more freedom on the windows behind the driver, which is why so many cars run darker rear glass and a lighter front.

The driver and front passenger windows must have a VLT of at least 35%. That is the darkest you can legally go on the front side glass.

Remember that factory car glass on the side windows already sits at roughly 70% VLT before any film goes on. The film and the glass are measured together, so you cannot simply add a 35% film to factory glass and land on 35%. The combined result will be darker than the film alone suggests.

Windows behind the driver can be tinted darker than the front. Rear side windows and the rear windscreen may go down to 20% VLT.

There is a catch. That 20% allowance only applies if your car is fitted with two rear-vision mirrors, one on each side. If your vehicle has a driver-side mirror only, then all the glazing behind the driver, including the rear side windows, rear quarter-glass and rear screen, must also be at least 35% VLT.

Most modern passenger cars come with mirrors on both sides, so the 20% limit will usually apply. It is still worth a quick check before you commit to a dark rear tint.

The windscreen is treated separately and cannot be tinted like the side glass. The windscreen must keep a VLT of at least 70% and must not be coated in film, with one exception.

You are allowed a tinted or opaque band across the top of the windscreen. That band can cover no more than 10% of the windscreen height, or the area above the swept arc of the wiper blades, whichever gives you the larger area. This is the classic sun strip and nothing more.

Tint reflectivity is capped as well. Film must not reflect more than 10% of light, so mirror-finish or highly reflective film is not allowed on any window. Spray-on tinting is prohibited, and so is film that has bubbled, peeled or been damaged to the point it impairs your view.

A measurement tolerance of up to 5% below the minimum is accepted, which allows for meter variation and the reality of installed film. Do not treat that tolerance as extra room to go darker. It exists for accuracy, not as a licence to push the limit.

NSW lists 326 window tinting businesses in our directory. A reputable installer will know these limits and can measure your existing glass before quoting, so ask about the finished VLT rather than just the film's rating.

These rules are made under the Road Transport (Vehicle Registration) Regulation 2017, Schedule 2 (Light Vehicle Standards Rules) and are enforced by Transport for NSW.

The figures in this guide were checked on 12 July 2026 against Transport for NSW guidance. Tint laws change and are enforced by Transport for NSW, so confirm the current limits with them before you tint.
