Why There Are Limits on How Dark Your Car Windows Can Be Tinted

It would be great if you could tint your car’s windows as dark as you want. The constant sunshine in many parts of Australia would make it nice to drive behind such a dark UV-reflecting window tint. Perhaps this will be possible when driverless cars are finally legally roaming the streets and the vision of the driver is not a factor in the safe operation of the car. But for now, there are varying regulations as to how dark your car window tinting can be. These regulations vary depending on which state or territory your vehicle is registered in. It’s vital that you adhere to these regulations. But why is it so vital? Surely it couldn’t hurt if your windows were just a little bit darker than what the authorities say is acceptable?

Reduced Vision

There are regulations in place pertaining to window tinting due to the fact that it can cause reduced vision when driving. The darker your windows are, the harder it can be to see (which is hardly surprising). This, when coupled with driving at night and/or with reduced visibility due to weather conditions, can result in a significant decrease in your ability to see the road. Having windows that are too dark can lead to traffic accidents.


If your vehicle has tinted windows and you’re involved in an accident, you can be sure that the darkness of the tint will be examined. You might be held liable for an accident if it was thought that your view of the road was diminished due to the darkness of your windows. Even when the accident clearly originated with another vehicle, your windows might have played a role in your ability to react and possibly avoid the accident.


There can also be serious financial implications. Your insurance company might choose not to cover you for the accident if the window tinting is deemed to be an illegal modification. It’s vital that you inform your insurance company when you have your windows tinted. You should tell them the percentage of the tint, while pointing out that it’s within the legal allowable limit in your state or territory. Of course, you should contact your local Department of Transport to find out these legal limits. It can be advisable to obtain documentation from the company that performed the tinting and to provide this to your insurance company. This covers you in a worst case scenario. There is the possibility that your insurance company might opt to increase your premiums after the tinting, but this is unlikely.


Illegal window tinting also mean that your car might fail its next roadworthiness certification. To overcome this, you will need to have the window tinting removed or replaced with compliant tinting to receive certification. This will of course mean that your window tinting can cost double what you originally thought it would.

There’s nothing wrong with having your windows tinted, and it can in fact be a great way to reduce the heat inside your car when done correctly. Just remember that there are limits on how dark it can be.
