Darkest Legal Tint for Cars: This is How Dark You Can Go On Private and Commercial Vehicles

We get lots of customers asking about the darkest legal tint for their car, and how dark they should go. The most common enquiry we get is, ‘What is the darkest legal tint for a private vehicle?’, which is our Black Tint.

Below is everything else you need to know about legal tints, including a few questions to ask yourself before deciding on a tint.

Private or commercial?

The darkest legal car window tint will depend on whether it is a private or commercial vehicle. Commercial vehicles are allowed darker tints than private ones.

New Car Window Tinting Laws QLD Sept 2017

As of September 2017, new laws apply to car tinting in QLD. Previously, a blanket rule for cars and vans applied, allowing a limit of 35% VLT on all side and rear windows.

The limits have been changed to allow darker film to be applied rear of the driver on passenger cars and no limit on ‘goods carrying vehicles’.

The new regulations can be found here;


Vehicles that come with Non-tinted Glass

Light passenger vehicle (not more than 4,500kg gross vehicle mass )

  • Not less then 20% (T20) for Tint to side or rear windows behind the driver’s seat as long as the vehicle has rear view mirrors fitted on both sides.
  • Not less than 35% (T35) for Tint to windows level to or in front of the driver’s seating position. This includes applied tint and factory tinted glass combined.


A goods vehicle’s window tinting can have 0% light transmittance as long as the vehicle has rear vision mirrors on each side.

However, please note:  Australian Design Rules allow privacy glass to the rear of the driver’s vision. There is no minimum light transmittance for Privacy glass so it is often darker than T35 tint. Privacy glass has tinted film in the glazing and so it doesn’t involve applied tint.

Vehicles that come 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 on the drivers and passenger front windows and 20% (T20) on the rear windows.

Black Tint

Black Tint was our darkest legal tint for private vehicles, and is definitely our most popular. With the new rules you can go to 20% (see above)

Black tint has a VLT (visible light transmitted) reading of 35%. This means that only 35% of natural light from the sun is allowed in through your windows.

If you apply a darker tint to a private vehicle (see new laws above), you may run into some problems. For example, the police might pull you over and make you remove the tint at your own cost (they have devices to test the VLT of your tint). Also, if you are involved in an accident, having an ‘illegal for road use’ tint may make your insurance claims invalid.

Commercial Grade Tints

According to the law in Queensland, commercial vehicles (for business use) are allowed darker tints than private vehicles.

Our commercial grade tints are available in 20%, 15%, 5% and 0% VLT.

So our darkest legal tint for commercial vehicles allows 0% of light to pass through your windows and into your vehicle.

Queensland car window tinting laws

Tinting laws in Queensland set minimum amounts of VLT (visible light transmitted) for your car windows. And your windscreen must have a higher VLT than your side and back windows.


Your car windscreen must be at least 75% VLT (for cars built after 1971)—which rules out most tints.

However, the top area of your windscreen (above where the wipers reach) can be tinted darker than 75% in a strip.

Back and side windows

Your back and side windows must be at least 35% VLT or 20% in some cases (see new rules above).

What state is your car registered?

Each state in Australia has different laws about how dark a tint can be. So, if you are planning on getting a tint done with us in Queensland, but your car is registered in another state (where you intend on driving it most of the time), this may cause issues.

You’ll need to do your research and check the relevant government website to make sure you’re not breaking any laws in that state before getting your car windows tinted with us.

Why do you want the darkest legal tint for your car?

When choosing a very dark tint, it’s important to make sure you’re choosing it for the right reasons. You may not need a dark tint to achieve the amount of heat, glare and UV reduction that you’re after.

Light and heat?

Many people choose the darkest legal tint for their car for sun protection and cooling reasons. Dark tints are naturally very good at reducing heat, light, glare and UV. So if reducing heat is your main concern, a dark tint is a good fit.

Security and privacy?

If you own a commercial vehicle, you may want a very dark tint for security reasons. Many businesses don’t want people to be able to easily see into their car windows—for example, when they’re parked in the street.

Dark tints can reduce theft and give added privacy for commercial vehicles.

UV rays?

Many customers want to reduce UV rays from entering their windows. This protects their skin as well as the car’s interior from fading. However, you don’t need a really dark tint to reduce UV rays.

Black Tint provides maximum Ultraviolet Protection Factor of 50+. But we also have other tints that are much lighter—such as the UV Shield and UV Clear—that offer the same 50+ protection.
