Road network

San Marino has no motorways. The republic sits on the steep slopes of Monte Titano, and every road inside its borders climbs or winds considerably. The main approach is a divided superstrada from Rimini, which connects to the Italian A14 autostrada on the Adriatic coast. There is no border checkpoint; the crossing from Italy is marked only by a sign. Once inside, roads narrow quickly as they ascend toward the old town. Large parking garages are cut into the mountainside on the lower approaches, and leaving the car there is the practical choice since driving into the upper streets is difficult and parking is scarce.

San Marino has no toll roads and no vignette. Drivers using the Italian A14 to reach the area will pay Italian motorway tolls on that stretch, so checking current rates before travel is advisable. Fuel is cheaper here than in Italy due to lower local taxes. Speed limits are 50 km/h in urban areas and 70 km/h on rural roads. Daytime running lights are compulsory at all times. The blood alcohol limit is 0.05 percent, the minimum driving age is 18, and winter tires are required from November 15 to April 15. Monte Titano receives snow in winter, and road conditions at the summit can differ sharply from those on the coastal plain below. The emergency number is 112. One detail that catches many visitors off guard: San Marino issues its own vehicle license plates, and locally registered cars are a regular sight on Italian roads throughout the surrounding region.
