If you arrive in Florence by car, it is worth paying attention at the ZTL, Restricted Traffic Zone.
Those who reach Florence by car must be informed about private traffic rules in the city centre. The historic center is not suitable for cars. In some part of it pedestrian areas or bus lanes are absolutely forbidden to traffic.
ZTL (Low emission zone) covers large parts of the historical centre and lots of tourist attractions, traffic-light controlled by telematic gates. The system -detecting the plate number of all the vehicles in transit- shows if the access is allowed (green) or forbidden (red).
ZTL schedule: Monday to Friday: 7:30-20:00; Saturday 7:30-16:00. ZTL is off on Sundays and holidays. From the 1st Thursday of April to the 1st Sunday of October the ZTL is extended to the night hours (23:00-03:00) on Thursday, Friday and Saturday.
If you are a tourist and your accommodation is located within the ZTL area, it is always possible to reach it; remember, in order to avoid a fine, upon arrival, you have to communicate your vehicle data to the accommodation facility staff so they will forward them to the Municipal Police.
Inside the ZTL area you cannot park for free, it is possible only in allowed spaces (hotel parking areas or private garages).
Parking facilities located outside the ZTL area have lower fares than those located inside it. There are also many parking spaces that borders the ZTL.
Peripheral areas, instead, have several parking lots, such as: Villa Costanza (Scandicci), Viale Guidoni, Via del Gelsomino, Via Sansovino, Viale Europa, well connected to the historical centre by public transport: Tramway and Bus.
The overall parking system is managed by Firenze Parcheggi ,Scaf, Metropark, Aeroporto
