1 scheme in 1 city. Every figure comes from an official source and is re-checked.
San Marino has 1 driving restriction that we have checked against an official source, in 1 city. It is a limited traffic zone.
This page lists no country-wide requirement for San Marino. Anything owed before you reach a city is not covered here, so check the national road authority before you leave.
The sources for this country were read on 2026-09-17, from the authorities' own pages. The check is repeated on a schedule, and a rule we can no longer confirm comes down instead of staying up.
San Marino has one driving restriction on our books: the Decreto Delegato 21 ottobre 2021 n.180 — Individuazione della Zona… (limited traffic zone). What is a limited traffic zone?

The historic centre of San Marino — the walled town on Monte Titano that carries the Palazzo Pubblico, the Basilica and the three towers — is a Zona Traffico Limitato, and the Republic created it in one sentence. Decreto Delegato 21 ottobre 2021 n.180 has a single article: the ZTL for the area of the old walls of the Città di San Marino (Centro Storico) is identified as shown in the plan at Allegato A.
That is the whole operative text. Everything else about how the zone works sits in two other places, and it is worth being precise about which, because the answer a driver needs is split between them. The first is the Codice della Strada, Decreto Delegato 26 maggio 2008 n.81, whose article 16 is the enabling power the decree cites.
Article 16 is headed Isole ambientali and defines three instruments an environmental island can use: zone a traffico limitato, which limit the NUMBER of vehicles circulating in a given area; zone 30, which impose a 30 km/h limit; and aree pedonali, for pedestrian movement only. It then says that limited-traffic zones and 30 zones are identified by a decree carrying plans at an adequate scale AND by adequate signage.
So the decree draws the line and the signs state the restriction — which means that what is written on the gate is part of the rule here, not a courtesy.
The second place is the Corpo di Polizia Civile, the police force that actually runs the zone: its published service charter says in as many words that the Sezione Viabilità manages tourist traffic and access to the Centro Storico, and it lists the permit that lets a vehicle in.
The permit is issued on the applicant's own request against a San Marino revenue stamp — 5 euro for someone resident in the Centro Storico, 15 euro for everyone else — together with the registration number to be authorised, and the charter cites as its legal basis a Regolamento per l'accesso e la sosta nel Centro Storico of 17 March 1997 and a Congress of State deliberation of 20 March 1995.
Three gates are named on the decree's own plan, and they are where a driver meets the zone: varco 1 is the Porta della Fratta, varco 2 is the junction of via Donna Felicissima, via Paolo III and via Gino Zani, and varco 3 is the Porta Nova.
One structural fact makes San Marino unlike most entries in this corpus and is the reason this record exists at all: the Republic is divided into nine castelli, each with an elected Giunta di Castello, but a Giunta does not legislate.
The state's own page on them says their functions are deliberative, consultative, promotional, supervisory and about running local services, and that it falls to the Giunta to PROMOTE decisions of the institutional organs. The ZTL of the capital is accordingly not a municipal act at all.
It is a decreto delegato of the Republic, promulgated by the Captains Regent on a Congress of State deliberation, and it is still in force: a decree-law of 12 August 2026 on the pastoral visit of Pope Leo XIV refers to it by number as the definition of the area it temporarily clears.
