ZTL (Zona a Traffico Limitato): Be very careful when driving! The historic centers of most cities are Limited Traffic Zones (ZTL), restricted to residents. Entering without a permit results in heavy fines that will arrive months later. It's better to park outside and walk.

Ticket Validation: When using regional trains or buses, you must validate ('convalidare') your ticket in the small green or yellow machines available on the platform or upon boarding the bus. Traveling with an unvalidated ticket can result in fines.

The 'Coperto': In many restaurants, you will see a charge called 'coperto' on the bill. It is a fixed fee per person for table service (bread, tablecloths, etc.) and is completely legal. It is not a tip.

Dress Code in Churches: To enter most churches, especially major ones like St. Peter's Basilica or cathedrals, modest dress is required. This means covering your shoulders and knees. It's a good idea to carry a scarf or shawl to cover up if needed.
