Paris Refuses a 2010 Euro 4 Diesel in 2026 — Crit'Air 3

Checked against official sources 19 Sep 2026 · Next review 2026-12-18

No. A 2010 diesel Euro 4 is classed Crit’Air 3, and Greater Paris has excluded Crit’Air 3, 4, 5 and unclassified vehicles from everything inside the A86 since 1 January 2025. The restriction bites Monday to Friday, 08:00-20:00, public holidays excluded. One reprieve applies: an educational period means no fine is issued before 31 December 2026.

Enter your vehicle's fuel + Euro class → instant verdict for Paris (ZFE). Fine if wrong: EUR 68 (cars, motorcycles, light commercial) / EUR 135 (HGV, buses, coaches) under art. R411-19-1 — not applied until 31 December 2026, while the metropolitan educational period runs and checks stay informational.

Can a diesel Euro 4 car enter Paris?

Not on a weekday daytime. The Ville de Paris states that “les véhicules catégorisés Crit’Air 5, Crit’Air 4, Crit’Air 3 et Non Classé ne peuvent pas rouler” in the metropolitan low-emission zone (paris.fr, updated 30 December 2025). A diesel certified to Euro 4 is Crit’Air 3 under the nomenclature set by the arrêté of 21 June 2016, so it falls inside that list.

The lowest class still admitted is Crit’Air 2, which for a diesel means Euro 5 or Euro 6, first registered from 1 January 2011. A 2010 build date sits one year and one class short of it — and unlike some borderline cases, no Certificate of Conformity reading changes the outcome if the car genuinely is Euro 4.

The fine that is not being issued yet

This is the detail most write-ups skip. The Métropole du Grand Paris runs an educational period to 31 December 2026, during which “aucune sanction ne sera appliquée” and roadside checks are occasional and informational. So driving this car into Paris on a Tuesday morning in 2026 breaks the rule without currently producing a fine.

That is a reprieve with a date on it, not permission. The penalty behind the rule already exists in law: article R411-19-1 of the code de la route makes it a third-class offence, fixed fine EUR 68 for a car, and a fourth-class offence at EUR 135 for HGVs, buses and coaches. If this car will still be making the trip in 2027, plan for the fine rather than around it.

  • Weekends. The car restriction runs Monday to Friday only.
  • Evenings and early mornings. Outside 08:00-20:00 the zone imposes nothing.
  • Public holidays. Explicitly excluded — “exceptés les jours fériés”.
  • 24 days a year on a pass. Crit’Air 3 vehicles get a 24-hour pass usable on 24 days annually.

What to arrange before driving in

  1. Check the CoC, not the year. If the car turns out to be Euro 5 rather than Euro 4, it is Crit’Air 2 and the verdict flips to yes.
  2. Order the Crit’Air vignette anyway, EUR 5.11 from certificat-air.gouv.fr. It is still required for the hours and the French ZFEs where this car is admitted.
  3. Use the A86 as the bypass. The motorway itself is outside the zone; the boulevard périphérique is inside it.
  4. Park & Ride at an outer RER station if the destination is central Paris on a weekday — it costs less than the eventual fine and far less than the argument.
