You must also remember that the speed limits are usually as follow:
ROAD

130 kph
Free highway (Superstrada)
110 kph
Outside of town
90 kph

50 kph
Please pay attention to the signs that indicate changing in speed limits above all in case of bad weather.
Other rules that have to be observe while driving in Italy and which have been recently brought in are indicated below:
