As of September 2026. Rules checked against the Polish regulation on vehicle technical conditions and the inspection regulation on 22.09.2026. Sources are listed at the end.
Poland's regulation on vehicle technical conditions says: front and front side windows must have a light transmission of at least 70%. It gives one figure for both. Nothing is set for the rear.
| Window | Poland | UK, for comparison |
|---|---|---|
| Windscreen | at least 70% | at least 75% |
| Front side windows | at least 70% | at least 70% |
| Rear side windows | no limit | no limit |
| Rear window | no limit | no limit |
If you drive a UK-legal car, its front glass is within the Polish figures as well.
Clear factory glass lets through roughly 78–80% of light on its own. That leaves a margin of a few percentage points above 70%. Dark tint film takes far more than that. Even very light film can push a window under the limit, because what counts is the reading on the glass with the film on it. The film maker's figure for the film alone doesn't matter here.
So in practice:
Behind the driver, Polish rules have no lower limit. Rear side windows and the rear window can take 50%, 35%, 15% or 5% limo film. The practical condition is working exterior mirrors on both sides, because you will rely on them at night. There is one limit on the rear too: no window may reflect light in a way that dazzles other drivers, and the inspection rules name reflective film.
Many cars already have privacy glass, tinted right through at the factory. It looks dark but absorbs heat and warms up. A film on top rejects infrared before it enters the cabin, so we often add film to privacy glass to cut heat.
When to go lighter: if you often reverse at night without a camera, 5% on the rear window makes that hard. On a car you drive mostly after dark, 15–35% is the easier choice.
Bought a used car and not sure the front windows are factory glass? Lower a front window by 2–3 cm and look at the top edge. Film shows as a separate thin layer that usually stops a millimetre or two short of the edge. Then look at the small glass maker's stamp in the corner: on film-covered glass it sits under a visible layer. If the front windows look darker than the windscreen, assume film until measured.
The inspection regulation lists two tint-related defects:
Rear film in good condition is fine at the inspection. The problem is peeling or bubbling film that limits the view.
A car on dark front film will also fail the inspection required before its first registration in Poland. Expats who import a car should plan for that.
Traffic police carry portable light meters. If the front windows read under 70%, you can expect:
For a Polish-registered car, retention is an entry in the central vehicle register (CEPiK). To get it back:
We do not offer film removal. If you bought a car with illegal front tint, a glass or tint shop that removes film is the place to go.
A car on foreign plates in international traffic is expected to meet its home country's technical rules. Whether the Polish 70% figure formally binds a foreign-registered car is not clear-cut, and we are not lawyers.
What is written in Polish law:
For a car you need to drive home, that means finding a shop to strip the film within the week. Keep the front windows clear and tint the rear however you like.
| Service | Price |
|---|---|
| Rear windows, hatchback or saloon | from 650 zł |
| Rear windows, SUV or estate | from 800 zł |
| Sun film on the windscreen | from 900 zł |
| Athermal film, windscreen and front side windows | from 1,500 zł |
Film types and the full process: window tinting in Kraków.
Yes, on the rear side windows and rear window, in any shade. The windscreen and front side windows must let through at least 70% of light.
The glass with film must read at least 70%. Factory glass starts at roughly 78–80%, so only very light athermal film fits.
Rear tint in good condition passes. Front windows under 70%, or damaged film that limits visibility, fail.
Yes. They can retain the registration certificate and fine you. A foreign document comes back once the film is off, if you reclaim it within 7 days; after that it goes to your embassy or consulate.
Tinting the rear windows costs from 650 zł on a hatchback or saloon and from 800 zł on an SUV or estate. It usually takes one working day.
