Since 2003, speed limits on Italian roads are being enforced more than before. There are speed cameras set up in many places. If you are speeding, you may get the ticket months later. It will go to your car rental agency and they will pay it from the credit card you used with them.

Cars and motorbikes (vehicles with engine size over 150 cc):

Urban areas - 50 km/h (31 mph)
Minor out-of-town roads - 90 km/h (56 mph)
Major out-of-town roads - 110 km/h (68 mph)
Motorways (Autostrada) - 130 km/h (81 mph)

In the event of rain on snow, the limit is lowered to 110 k/h on motorways and 90 k/h on trunk roads.

In order to ensure that these limits are complied with, numerous speed cameras have been installed throughout the road and motorway network to keep electronic checks on speed.
