Why can't a Euro 4 diesel enter Warsaw now?

The Clean Transport Zone moved to its second stage on 1 January 2026, when the diesel minimum rose to Euro 5. A 2010 Euro 4 diesel met the first-stage rule but falls short of the current one. The zone checks the Euro class on the registration, not the model year.

How much is the fine in Warsaw's zone?

Up to PLN 500 (roughly EUR 115). Poland enforces the zone with checks and cameras, and the rules apply to foreign-registered cars as well as Polish ones.

Do Warsaw residents follow the same rule?

Not exactly — cars registered to residents of Warsaw have a more lenient transitional standard, so a local Euro 4 diesel may still be allowed while a visitor's is not. If you're driving in from outside the city, plan around the stricter visitor rule.

What's the alternative if my diesel can't enter?

Use a Park & Ride (Parkuj i Jedź) on the edge of Warsaw and continue by metro, tram or bus. It's a fraction of the fine and avoids the zone entirely.

Are any diesels or cars exempt?

Fully electric and hydrogen cars are exempt, as are certain historic vehicles. A 2010 Euro 4 diesel is none of these, so no exemption applies — only meeting the Euro 5 minimum or leaving the car outside the zone will do.

Can a diesel Euro 4 car enter Warsaw?

No — not since the start of 2026. Warsaw’s Strefa Czystego Transportu (SCT) tightens in stages, and the step on 1 January 2026 raised the diesel minimum to Euro 5. A 2010 diesel is Euro 4 at best, so it no longer qualifies for the zone, which covers the city centre and inner districts.

What the zone checks is the Euro class on the registration document, not the age or condition of the car.

What it costs

The fine is up to PLN 500 (about EUR 115). Poland enforces the SCT with roadside checks and cameras, and foreign-registered cars are subject to the same rules as Polish ones.

One important exception

Cars registered to Warsaw residents follow a more lenient transitional standard, so a local Euro 4 diesel may still be allowed. If you are driving in from elsewhere, you are held to the stricter visitor rule — don’t assume a neighbour’s car being fine means yours will be.

What to do instead

Park & Ride (Parkuj i Jedź). Leave the car at a P+R on the edge of Warsaw and take the metro, tram or bus into the centre.
Compliant vehicle. Only diesels meeting Euro 5 (or electric and hydrogen cars) may enter freely.
