Car window tinting is a popular way to add style, reduce heat, and protect your interior from harmful UV rays. But did you know that not all window tints are legal? In South Australia, there are strict rules about how dark your car windows can be tinted. Understanding these rules is important to avoid fines and ensure safety on the road.
In this guide, we will explain what window tint is legal for cars in South Australia, what the rules are, and how you can make sure your Tint is within the law.
What is Car Window Tinting?
Car window tinting is the process of applying a thin, colored film to the windows of your vehicle. This film can be tinted to different shades, which is measured by the Visible Light Transmission (VLT) percentage. The VLT tells you how much light can pass through the window. A lower VLT means the Tint is darker, while a higher VLT means the Tint is lighter.
While darker tints can help block out the sun and keep your car cooler, it’s important to stay within the legal limits set by the law.
Legal Car Window Tint in South Australia

In South Australia, car window tinting must follow specific regulations to ensure safety and visibility. The legal limits for window tint are based on the VLT percentage, which is the percentage of visible light that can pass through the window.
Here are the key rules for car window tinting in South Australia:
- Windshield: The windshield (front window) can only be tinted in the top 10 cm. This area is allowed to have a VLT of 70% or more, meaning it can be lightly tinted to block out some glare but still allow plenty of light through.
- Front Side Windows: These windows (the ones next to the driver and front passenger) must allow at least 35% of light through. It means the Tint must have a VLT of 35% or higher. If your front windows are too dark, it could be illegal.
- Rear Side Windows: These windows can be darker than the front side windows. They must allow at least 20% of light through (a VLT of 20% or higher), but they can be darker if you prefer more privacy.
- Back Window: The back window can be tinted as dark as you want. However, if the Tint is too dark, you must have side mirrors installed so you can still see out clearly.
Why Are These Laws Important?
Car window tinting laws exist to ensure safety on the road. If your windows are too darkly tinted, it can make it hard for you and other drivers to see clearly. It is especially important when driving at night or in low-visibility conditions, like rain and fog.
Tinting your windows within the legal limits ensures:
- You can see clearly when driving.
- Others can see you when you’re on the road.
- You stay safe by not blocking too much light.
Penalties for Illegal Tinting

If you have illegal window tint on your car, you could face penalties. Law enforcement can pull you over and check your window tint with a special tool that measures the VLT. If your Tint is too dark, you might receive a fine or be asked to remove the Tint altogether.
Here are some possible consequences:
- Fines: If your Tint is illegal, you could be fined.
- Defect Notices: If your Tint is too dark, you might receive a notice to fix it.
- Removal of Tint: In some cases, you may be required to remove the illegal Tint entirely.
How to Make Sure Your Tint is Legal
To ensure your car’s window tint is legal, follow these simple steps:
- Know the Legal Limits: Familiarize yourself with the VLT percentages for different windows on your car. For example, front side windows must have a VLT of at least 35%, while rear side windows can go down to 20%.
- Get Professional Installation: A professional window tinting service can install the correct Tint and ensure it meets the legal limits. They will also provide you with a certificate confirming that your Tint complies with the law.

- Ask About Certification: Always ask the installer if the Tint they’re using is certified and meets South Australian regulations. Certified films will have labels showing their VLT so that you can verify their legality.
