Driving the Amalfi Coast means navigating the SS163 Amalfitana, Positano ZTL cameras, hotel whitelist procedures, and rental-car insurance gaps that can turn a short transfer into a €165–€434 penalty plus agency fees. This guide covers the legal no-go points for Positano, Amalfi, Ravello, and Capri, with practical routing advice from Naples Capodichino (NAP), Rome Fiumicino (FCO), and Salerno Costa d'Amalfi. Two rules matter first: ANAS Ordinance 340/2019 can activate the alternating plate system on the SS163 Amalfitana between 10:00 and 18:00 on designated dates, and Codice della Strada Article 7 governs the camera-enforced ZTL in Positano, Amalfi, and other municipal centres. A rental car in violation can trigger municipal fines of €120–€350 plus agency handling fees, with notices usually processed through the rental desk and later charged to the card on file. These rules apply to rental cars from Avis, Europcar, Hertz, Sixt, Enterprise, Goldcar, Locauto, InterRent, Firefly, Sicily by Car, Primerent, King Rent, Hire Car Positano, Positano Vintage, Positano Car Service, Positano Rent, Rental Car Positano, and Positano.com. Scooters and motorcycles are generally exempt from the plate-restriction system, but they are not exempt from ZTL camera enforcement if they enter restricted urban zones. If you are landing at Naples Capodichino (NAP) or Rome Fiumicino (FCO), compare the rental desk’s plate assignment before you commit to the SS163 route; the same booking can produce an odd or even plate, which affects whether you can legally drive at 10:00–18:00 under ANAS Ordinance 340/2019. A rental company can still bill you for the municipal fine, a notification fee, and its own administration fee even when the traffic offense happened days earlier; under Article 7 Article 142, the ticket often arrives after your trip and the car hire operator—Avis, Hertz, or a local broker—recharges the card later. ANAS Ordinance 340/2019 is the core traffic restriction on the SS163 Amalfitana, designed to reduce congestion on the coastal route between Vietri sul Mare, Cetara, Maiori, Minori, Amalfi, Atrani, Conca dei Marini, Furore, Praiano, and Positano. On even-numbered calendar days, even plates may circulate; on odd-numbered days, odd plates may circulate, usually from 10:00 to 18:00. The restriction covers the coastal axis from Vietri sul Mare to Positano, while access routes such as the A3 Napoli–Salerno motorway, the SS145 Sorrento Peninsula road, the SR 366 Agerolina, and the Provincial Road Valico di Chiunzi are commonly used to bypass the most restricted stretch. In practice, drivers heading to Ravello, Amalfi, or Montepertuso often choose inland routing to avoid a plate mismatch. Official exemptions include residents of the Amalfi Coast municipalities and Agerola, vehicles with a valid disabled permit, taxis, NCC chauffeured vehicles, police, emergency vehicles, and public utility vehicles. A rental car from Positano Rent, Rental Car Positano, or King Rent does not qualify for a special exemption unless the plate is already exempt by status. If your rental car is blocked by plate parity, wait until 18:00, then drive after the restriction ends, or use the off-hours window before 10:00 to reposition through the SR 366 Agerolina toward Ravello or Amalfi. Hotel guests can sometimes use a temporary whitelist, but the hotel must submit the plate to the municipal portal in time; under the operational practice used by Comune di Positano and Polizia Stradale checkpoints, a paper reservation confirmation is safer than a phone screenshot. The Positano ZTL is a camera-enforced Limited Traffic Zone governed by Codice della Strada Article 7, and it is designed to keep non-resident traffic out of the historic centre near Via Pasitea, Via G. Marconi, Via dei Mulini, Spiaggia Grande, and the walkways leading toward Fornillo and Montepertuso. A vehicle entering the zone without authorization can be photographed automatically at the access gates. The fine structure typically includes a municipal penalty of €83–€332, an administrative notification charge of about €42, and a rental agency surcharge of roughly €40–€60, which can bring the practical total to about €165–€434 per entry. Comune di Positano and Polizia Stradale enforcement can be reviewed under the ZTL signage regime, and under Article 7 the camera record is enough to create liability.
