It is useful to remember that free camping in Sardinia is not always possible, but there are authorised stop-over sites that can also be used for the discharge of water and rubbish.
At all airports and in major cities you can rent cars and other vehicles. In the high season it is best to book them in advance. Besides the B license (or equivalent if you are not Italian) you may be required a to provide a credit card in the name of the driver.
In summer, especially along the coast, the roads are very busy, so please take that into account when planning your journey and remember that, when not signposted, the speed limit is 50 km/h inside built-up areas and 90 km/h for non-urban roads.
Remember that it is illegal to drive after taking alcohol or drugs and also to throw rubbish out the window, especially cigarette butts due to the risk of fire. In inland areas of the island pay attention to wild animals that may cross the street.

The railway line connects Cagliari with Sassari, Porto Torres, Golfo Aranci, Iglesias and Carbonia. Buses connect all locations, including the smaller ones. In major cities there are special lines of urban transport. In the case of long journeys you will need to change your means of transport - check the site http://www.sardegnamobilita.it/ for timetables, travel times and connections.

The island can be crossed by the SS 131, a fast dual carriageway that connects Cagliari to Sassari and Porto Torres. From the Abbasanta junction the road forks to Olbia through Nuoro: other fast roads intersect with the 131 connecting other locations. Cagliari is connected with the SS 130 in the south west of the island and with the new SS 125 at the eastern part and up to the north.
Petrol stations are located along the main arterial roads but also in towns crossed by the dense network of secondary roads.
