Driving in Monza

Italy: 1 scheme to know about before you drive in.

The short answer for Monza

Monza has one driving restriction on our books: the Misure permanenti per la limitazione del traffico veicolare (Regione… (low emission zone). What is a low emission zone?

What it means for your car

Petrol or LPG. Euro 1 and below, for petrol, methane and LPG alike. The region bans Euro 0 vehicles "benzina, metano, GPL o diesel" and Euro 1/I vehicles on the same four fuels in both Fascia 1 and Fascia 2 municipalities, during the weekday window. Above that line petrol is not restricted at all by this scheme: there is no Euro 2, Euro 3 or Euro 4 petrol step anywhere in the permanent measures, and the Euro 5 phase-in that was to begin on 1 October 2026, and that the region postponed to 1 October 2027 on 28 September 2026, was written for diesel only. Nothing about a petrol, methane or LPG vehicle changed either way. A petrol car fitted with a natural-gas or LPG system — from the factory or retrofitted, and including bi-fuel installations that keep the petrol tank — is excluded from the ban outright provided the vehicle is of class Euro 2/II or better, which is a more generous line than the one that catches petrol on its own. Two-stroke mopeds and motorcycles are handled by their own rule rather than by fuel, and it is stricter than anything the car list contains: Euro 0 two-strokes are banned across the whole region seven days a week and round the clock.
Diesel. Euro 4 and below. This is the line that decides most visitors' cases, and it has two steps today where until 29 September 2026 this record described three. First, the region bans diesel of Euro 0, Euro 1/I, Euro 2/II and Euro 3/III in both Fascia 1 and Fascia 2 municipalities. Second, it bans Euro 4/IV diesel as well, but only in Fascia 1 municipalities and in the Fascia 2 municipalities over 30 000 inhabitants — four since 28 September 2026, Varese, Lecco, Vigevano and Abbiategrasso, S. Giuliano Milanese having been dropped; Monza is Fascia 1, which its own council states in terms — "Il Comune di Monza rientra tra i Comuni in fascia 1" — and which the region's own band list confirms by naming MONZA under province code MB inside the ELENCO COMUNI FASCIA 1. So the diesel floor in Monza is Euro 5. 🚨 THE THIRD STEP WAS TWO DAYS AWAY AND HAS BEEN POSTPONED TO 1 OCTOBER 2027. Until 28 September 2026 the governing act was d.G.R. n. 4843 del 28/07/2025, under which Euro 5/V diesel cars of category M1 would have been banned from 1 October 2026 in the urban areas of municipalities over 100 000 inhabitants, the region naming all four: "Comuni aventi popolazione superiore ai 100.000 abitanti (Milano, Brescia, Monza e Bergamo)". It phased the step by vehicle category — M1 cars from 1 October 2026, M2, N1 and N2 from 1 October 2027, everything else from 1 October 2028. On 28 September 2026 the region adopted d.G.R. XII/6846, which resolves «il rinvio delle limitazioni alla circolazione per i veicoli diesel Euro 5 al 1° ottobre 2027» in implementation of decreto-legge 28 settembre 2026, n. 167, and whose Allegato 1 «modifica e sostituisce l'Allegato 1 della d.G.R n. 4843 del 28/07/2025». ✅ Read on 2026-09-29, that replacement Allegato 1 lists the banned classes in full and stops at Euro 4/IV diesel: no Euro 5 row, and no 100 000-inhabitant threshold anywhere in its scope section. The region's own page puts it in terms: «non entrano in vigore dal 1° ottobre 2026 le limitazioni per i veicoli Euro 5 diesel previste dalla delibera n. 4843 del 28 luglio 2025, mentre restano confermate le limitazioni per le altre categorie fino a Euro 4 diesel». ⚠️ Because the 2025 Allegato was replaced outright rather than amended date by date, this record states no future date for the M2/N1/N2 and N3/M3 phases either. A diesel of any class fitted with an abatement system effective against both particulates and nitrogen oxides is excluded, but the bar is high and was deliberately raised: the system must hold real-driving emissions at or below the values set for Euro 6 D / Euro VI diesel, and since 1 October 2024 a filter that only removes particulates no longer counts for any vehicle.
