To pass a NSW pink slip inspection and avoid a police defect notice, your vehicle needs to meet these Visible Light Transmission percentages. VLT is simply the percentage of visible light that passes through the glass and film together. Lower number, darker window.

Source: Transport for NSW, Light Vehicle Safety Check Standards, Rule 105.03, March 2025.

Reflective and mirror finish film is not permitted on any window, and neither is spray-on tinting, regardless of how much light gets through.

The inspection standards give examiners two numbers per window rather than one. One is the legal minimum. The other is the point where the examiner has to fail you. The gap is there because the meter itself can be up to 5% out.

Do not get excited about that second column. The legal minimum is still 35% and 20%. The lower figure is meter tolerance, not a licence to fit a 30% film to your front windows and argue the point at the roadside. Police issuing a defect notice work to the limit, not the tolerance, and a film ordered at 30% will read closer to 25% once it is sitting on factory glass. We aim for a comfortable margin above the minimum so your reading is never a coin toss.

Your factory glass is not clear. Most modern cars leave the factory at somewhere around 70% to 80% VLT on the front side windows because of the tint in the laminate. When a 35% film goes onto 75% glass, the combined result is roughly 26% VLT, which is illegal, even though the film itself was sold as a legal 35%.

This is the single most common reason a car fails a tint check. The film was compliant. The finished window was not.

Rear windows work differently, and this is where the advice online is usually wrong. Factory glazing is exempt from the light transmission requirements. The inspection standards state plainly that the requirements do not apply to glazing fitted as equipment by the vehicle manufacturer, which is why a new SUV can roll out of the dealership with rear glass well under 20% and be perfectly legal.

Film changes that. The reading taken at inspection covers the window including any applied film. If your rear glass already sits near 20%, there is very little room left to work with behind the driver. If your rear side windows carry a small stamp reading “Privacy” near the edge, that is what you are dealing with, and it needs metering before anyone quotes you. There is a fuller answer on how much darker your back windows can go if that is the main thing you came here for.

The reasoning is set out in the Transport for NSW standards sheet, and it is not what most people assume. Windscreen manufacturers advise the glass already filters out at least 98% of UV, and the film manufacturers themselves advise that medical grade film, the film used to protect people with skin conditions, is clear and does not reduce visible light transmission at all. So there is no UV argument for darkening a windscreen, and there is a straightforward safety argument against it. That is why film is not generally permitted on the main area of the glass, and we go through what you can and cannot do to a front windscreen in more detail on its own page.

Two more rules trip people up. Reflective or mirror finish film is not acceptable because it can dazzle other drivers by bouncing back sunlight or headlight beams. Spray-on tinting and finishes are not acceptable at all. And any film that is damaged, bubbled or discoloured to the point that it affects the driver’s view has to come off, along with the leftover adhesive, before the vehicle will pass.

1. Save the blueprint table above to your phone so you can hold an installer to it.
2. Look along the bottom edge of your rear side windows for a privacy glass stamp.
3. Ask your installer to put a VLT meter on your bare glass before you choose a film, then ask them to state the expected combined figure. If they cannot do this, book somewhere else.

At EverClear Window Tinting we meter every vehicle before we recommend a film, and we meter it again once the film is on. You leave with a finished window we can stand behind at a roadside check.

Choose 35% for the front side windows because the law requires it, and because it keeps your night vision intact. Choose 20% on the rear if you want genuine privacy for passengers, child seats, or tools in the back.

For most drivers the answer is a 35% front and 20% rear combination, which is the darkest legal configuration available on a standard passenger car in NSW.

35% VLT. The legal maximum darkness for front side windows. Comfortable to drive at night, including reversing out of a dark driveway or reading a poorly lit street sign. From outside, someone can make out your silhouette but not much detail. On a quality ceramic film this level still rejects the vast majority of infrared heat.

20% VLT. The legal maximum for everything behind the driver. Noticeably darker from outside and effective at hiding bags, tools, or car seats in the rear. Rear visibility at night is reduced, though your side mirrors do most of that work anyway. If that worries you, we have covered whether it is illegal to not be able to see out your back window separately.

15% and 5% (limo). Illegal on NSW roads on every window of a standard passenger vehicle. These levels belong on show cars and off-road vehicles only. At 5% you are effectively driving blind at night, and no insurer wants to hear about it after a crash. If you want a sense of just how little gets through, have a look at what you can actually see out of 5% tint.

• Do you struggle with night vision, or drive a lot after dark? Stay at 35% all the way around.
• Do you carry tools, or have kids in the back? Go 35% on the front and 20% behind the driver.
• Is heat the real problem, not privacy? Do not go darker. Go better. A 35% ceramic film blocks far more heat than a 5% dyed film, and it is legal.

This is where most people get it backwards. Twenty years ago darkness and heat rejection went hand in hand, because dyed films worked by simply blocking light. Modern ceramic film separates the two. Our ceramic range rejects up to 96% of infrared heat at legal VLT levels, and we can even do it on a near clear film if you want the performance without the look. There is more detail on our ceramic tint and invisible tint pages, and on how IR rejection is measured.

If you have a diagnosed photosensitive condition, medical grade film is clear film. It does not reduce your VLT and it does not require any kind of exemption. Talk to us and we will fit a clear ceramic film that manages UV and heat without touching your light transmission.

Driving with film darker than 35% on the front side windows or 20% behind the driver is a non-compliant vehicle offence in NSW. The on the spot fine sits at approximately $349 along with three demerit points. Penalty amounts are indexed each year, so check the current Revenue NSW schedule for the exact figure.

Three exemptions are worth knowing, because they get misquoted constantly.

Goods vehicles. Utes and vans get a different rear window rule. Under the current inspection standards there is no VLT limit at all on the rear windows of a goods vehicle with at least four wheels, which covers most dual cab utes and commercial vans. One catch: if the vehicle does not have a passenger side rear vision mirror, the rear windows still have to meet 35%. The 35% minimum on the windows beside the driver always applies, with no exception. Your compliance plate is the little alloy plate in the engine bay or on the front door pillar. Send us a photo of it and we will sort your category before we pick a film.

Mirrors change the rear limit. The 20% rear allowance assumes your vehicle has a passenger side rear vision mirror. Without one, the rear windows have to meet 35% instead, whatever you drive. The same standards also require external mirrors on both sides once the VLT of any side or rear window drops below 70%, which in practice means the moment you tint.

Vehicles built before August 1994. Got something built before August 1994? There is no limit on any window but the windscreen, as long as the glass or the film went on before that date. Fit new film to a classic and it has to meet the current limits like anything else. If you are building something and want a statement finish, our coloured tint page covers what is possible.

It is legal to apply tint to your own vehicle in NSW, as long as the finished result complies. Whether you should is another question. This job is not about effort. It is about conditions and equipment. Not to mention, it is very easy to do it wrong if you aren’t properly trained.

Run this three point test before you buy a kit.

1. Do you have a fully enclosed, dust free space? A single speck of dust trapped under the film shows up as a permanent white bubble. Driveways and open carports do not qualify.
2. Do you have a proper heat gun? Film has to be heat shrunk to match the curve of the glass. A hairdryer will not do it, and unshrunk film creases and lifts within weeks.
3. Are you prepared to remove the door trims? Film needs to be tucked below the window seal. Cut it at the seal line and it will peel from the bottom edge.

If you answered no to any of those, skip the kit. The cost of buying it, ruining it, and then paying someone to remove a sticky half finished mess is more than the professional job would have cost from the start. Remember too that film which has bubbled or discoloured badly enough to affect your view is itself a reason to fail a safety check, so a poor DIY job can cost you a pink slip as well as the film. DIY film also carries no manufacturer warranty against bubbling, fading, or delamination.

EverClear Window Tinting has been fitting window film in Sydney for more than 20 years. We are an authorised XPEL dealer, a member of the Window Film Association of Australia and New Zealand, and we have over 150 five star Google reviews from drivers across the Hills District and greater Sydney.

Our process for a legal tint job:

1. Meter your factory glass so we know the starting VLT on every window.
2. Confirm your vehicle category, because a ute and a wagon are not held to the same rear window rule.
3. Recommend a film that lands the combined result comfortably inside the legal limit, front and rear, or you can choose any percentage you like.
4. Fit the film in a controlled, dust managed workshop, with the door trims dropped so the film tucks properly.
5. Meter the finished windows and confirm compliance before you drive away.

Every automotive film we fit carries the XPEL lifetime manufacturer replacement warranty covering discolouration, bubbling, peeling, cracking, and delamination, including parts and labour. The warranty is transferable to the next owner and is honoured at authorised XPEL installers across Australia. On top of that, our own workmanship guarantee covers the installation itself.
