Can Back Windows Be Tinted Darker?
Articles > Can Back Windows Be Tinted Darker
Thinking about getting your car windows tinted and wondering if the back ones can be darker? It’s a common question, especially if you’re aiming for more privacy or a sharper look.
In Australia, tinting laws differ by state, and what’s permitted in one place could be illegal in another. Going too dark on your back windows could result in fines, failed inspections, or even voided insurance.
Tint a Car have been helping Australians navigate these decisions for over 42 years. We use ARPANSA-certified films, offer a lifetime warranty on most tints, and only install films that meet Australian legal standards. That includes Octane, the darkest legal tint available nationwide.
Back Windows Can Be Darker, Within Legal Limits
Many drivers assume that rear window tints are less regulated. It’s true that most states allow darker tint on back windows than on front side windows. But there are still clear legal limits on how dark you can go.
These limits are measured by Visible Light Transmission (VLT). The lower the VLT, the darker the tint. For example, a 20% VLT film only allows 20% of visible light to pass through.
No matter how much privacy you want, you can’t go below your state’s legal VLT percentage for rear and back side windows.
Legal Tint Percentages by State
Below are the maximum legal VLT percentages for rear and back side windows across each state and territory in Australia:
| State | Back Side Windows (VLT%) | Rear Window (VLT%) |
| ACT | 20% | 20% |
| NSW | 20% | 20% |
| NT | 15% | 15% |
| QLD | 20% | 20% |
| SA | 20% | 20% |
| TAS | 20% | 20% |
| VIC | 20% | 20% |
| WA | 20% | 20% |
These limits apply to private passenger vehicles. Commercial and special-use vehicles may differ. Read our guide to darkest legal tints for more information.
Why Legal Limits Exist
The rules aren’t there to spoil your style, they’re about visibility and safety. Tint that’s too dark can restrict your view at night or in low-light conditions. It can also prevent police or emergency responders from seeing inside the vehicle when needed.
By enforcing these VLT limits, authorities ensure that drivers get the benefits of tint, like glare reduction and UV protection, without compromising road safety.
What Happens If You Go Too Dark?
Pushing past the legal limit may seem harmless, but it can have real consequences:
- Fines or defect notices from police
- Failed roadworthy inspections or registration issues
- Voided insurance claims in the event of an accident
- Extra costs for tint removal and reinstallation
We make it simple to stay compliant. Our team checks local laws and recommends the best legal option for your state.

Common Questions About Back Window Tinting
Can I tint darker with a medical exemption? Yes, but only in some states and only with approved documentation. Check with your local transport authority or contact a Tint a Car expert for specific guidance.
Why do other cars look darker than mine? Some vehicles come with factory privacy glass, which can appear darker. Others may be illegally tinted. Keep in mind that optical darkness isn’t always about VLT alone, film quality and colour density also matter.
Is 20% VLT dark enough for privacy? Absolutely. High-quality films like Octane use a deep black tone to maximise perceived darkness, even at legal limits.
Will window tint affect my phone, GPS, or radio? No. Our films are designed with non-metallic, signal-friendly technology, so you can stay connected without interference.
