Window Tinting Laws in Australia: What’s Legal & What’s Not?
For many drivers in Western Australia, window tinting is a sought-after upgrade for its sleek look, enhanced privacy, and protection from the harsh Australian sun. However, navigating the legal requirements can be a challenge. At Trident Car Care, we believe in keeping your vehicle both stylish and street-legal. This guide breaks down exactly what’s permitted on WA roads.
Why Tinting Laws Exist
Window tinting regulations are not arbitrary; they are carefully designed to balance the benefits of tint—such as reduced glare, UV protection, and improved cabin comfort, with critical safety considerations. These laws ensure drivers maintain sufficient visibility, particularly during night driving or in low-light conditions, and that law enforcement can see inside a vehicle when necessary. Non-compliance can result in significant fines and your vehicle being deemed unroadworthy .
Western Australia’s Tinting Regulations Explained
The laws in WA are clear and specific. The darkness of tint is measured by Visible Light Transmission (VLT), which is the percentage of visible light that passes through the window film and glass.

Here’s a quick overview of what’s legal:
Windshield: Only the top 10% of the windshield can be tinted. This is typically a shaded band that must not extend below the highest point swept by the windshield wipers. Clear, non-reflective UV shields are also permissibl.
Front Side Windows: These must allow at least 35% of visible light (VLT) to pass through. This ensures sufficient visibility for drivers.
Rear Windows: All windows behind the driver, including the rear windshield and back side windows, can have a darker tint, with a minimum 20% VLT.
Additional Important Rules
Reflectivity: Tints with more than 10% reflectivity are prohibited, as they can dazzle other drivers.
Mirrors: If rear windows are tinted below 35% VLT, dual exterior rearview mirrors are mandatory.
Film Quality: Bubbled, discoloured, or damaged tints that impair vision are not allowed.
Medical Exemptions and Vehicle Exceptions
WA does allow exemptions for certain medical conditions that require a higher level of sun protection. If you qualify, you’ll need to seek approval from the Department of Transport’s Vehicle Safety and Standards unit.
Furthermore, specific commercial vehicles like trucks, vans, hearses, and buses may have darker tints on all windows behind the driver, as their design doesn’t require inward visibility for driving. It’s important to note that SUVs are generally not included in this exception.
