The SS1631 Amalfitana keeps cars with an odd last plate digit off the road on odd-numbered days and even plates on even days, between 10 am and 6 pm, under Anas ordinance 3401/2019.
10 am to 6 pm, and the last digit of your plate
The window is 10 am to 6 pm (10:00 to 18:00 on Italian signs). Inside it, on an odd-numbered day, a plate ending in 1, 3, 5, 7 or 9 is not allowed on the SS1631 Amalfitana; on an even-numbered day, plates ending in 0, 2, 4, 6 or 8 stay off.
Before 10 am and after 6 pm the road takes every plate. That is the single most useful line on this page: the restriction is a shift, not a closure, and an early start beats any workaround.
Nothing on your dashboard will tell you
The 5 Italian cities we verified for camera-gated zones, Rome, Florence, Milan, Naples and Bologna, all restrict a drawn area with a gate you cross, and an unauthorized plate gets a penalty issued automatically.
The SS1631 rule is not one of those. It is a date condition applied to an entire state road, with no gate to cross and no polygon to draw, so a navigation app that knows about restricted zones has nothing to match it against.
That gap is why so many drivers meet the rule for the first time at a police check on the road, having planned the day on a phone that stayed silent.
The practical consequence is that the SS163 ha1s to be planned on a calendar, the way you plan a museum closing day. Look up the date, look at your plate, and decide the hour you leave. Nothing about the car or the route changes the answer.
The 2026 dates we could actually verify
In 2026 the restriction was applied from March 30 to April 6 and from April 24 to May 2, on the municipal notice we read.
Those two windows sit on Easter and on the April 25 and May 1 holidays, which is the pattern: the rule comes out when the road fills, not for the whole season.
Local press also reports August, September and October weekend dates. We could not open the Anas ordinance or any institutional notice confirming that calendar, so it is not printed here as fact. Before a summer drive on the coast, check the comune's own notices for the dates.
7 categories are exempt, and one of them may be you
The 7 exempt categories are residents of the Costa d'Amalfi comuni, vehicles with a disability permit, taxis and NCC cars, emergency and police vehicles, hotel guests with a booking, non-resident workers with a contract, and owners of a house on the coast holding a certificate from their comune.
The hotel line is the one that changes most trips. If your accommodation is on the coast and your booking is confirmed, the restriction is not aimed at you, but the booking has to exist and be produceable at the roadside.
Sources disagree on how many comuni make up the exempt area: 13 or 14 towns of the Costa d'Amalfi, plus Agerola. That is a real ambiguity in the published material, not a rounding.
Motorbikes are outside the rule entirely
The measure applies to cars only: motorbikes and scooters were not subject to the alternating plates on any of the 2026 dates.
It is the reason the road looks the way it does on a restricted afternoon, and the reason a scooter rental is a rational answer to a specific problem rather than a lifestyle choice. It also means a rented car with the wrong final digit is only a problem for 8 hours of the day, and only on the dates the ordinance is actually switched on.
If you are driving anywhere else in the region, the ordinary Italian rule still applies: historic centers are camera-gated zones, the fine is issued automatically, and it can reach your home address months after the trip. See Campania for the wider picture.
