In Sardinia, there are no highways, so there are no tolls to pay.
At the same time, although the main roads are four-lane roads, they do not have an emergency lane. The speed limit is 90 km/h, with a few exceptions in the vicinity of Cagliari.
Like in the rest of Italy, it is mandatory to keep the headlights on during the day for safety reasons.
Certain roads have fixed speed control systems, and they are indicated. However, most of the time, the police conduct speed checks by positioning radars in different locations across the island for a few hours.
The lands hosting animals near the roads are fenced, but it is always advisable to be cautious of possible animals on the roads. You may even encounter a flock of sheep on the asphalt as they move from one flock to another.
The speed limits in urban areas are certainly lower, and Olbia, for example, is among the first cities in Italy to adopt a 30 km/h speed limit within the urban perimeter.
Street parking is possible where indicated. Parking areas with white lines are free, while those with blue lines require payment. You can pay using parking meters or various parking payment apps (the specific apps vary depending on the location).
Amongst the most commonly used to pay your parking: Easypark e MooneyGo.
