Almost places are very well connected by train or by bus SII (http://www.sii.bz.it/en/benvenuti.php) and roads are considered to be the best well-kept in Italy and road signs are not an exception or ambiguous.
By car
Also the smallest and most isolated mountain village is well connected through well-kept road. In South Tyrol there are three kind of roads: local roads, provincial roadsSP/LS meaning Strada Provinciale/LandesstraÃe and statal roads SS meaning Strada Statale/StaatsstraÃe - however both provincial and statal roads are run by the regional government of South Tyrol. Highway A22 is a toll road and paying is compulsory. In South Tyrol police seems to be much less tolerant than in other parts of Italy, so pay attention and keep to the rules.
Traffic signs are always very precise and the usage of pictographs is more common than in other parts of Europe since in South Tyrol two or three languages have to be used. In most parts of South Tyrol signs are written in the German/Italian order, while in Bolzano and other smaller Italian-speaking areas in Italian/German. Also complimentary information is bilingual. In the Ladin-speaking valleys road signs are trilingual - Ladin/German/Italian.
Speed limits are:
130 km/h on highways green traffic sign;
110 km/h on freeways blue traffic sign - similar to a free highway;
90 km/h on single-lane roads blue traffic sign;
50 km/h inside cities after the white traffic sign on which is written the place name.
Italian laws allow a 5% tolerance on local speed limit and fines are generally very expensive.
Motorbikes should drive always with the headlights on, for other vehicles that applies only outside cities. In mountain roads there are a lot of accidents involving bikers - so pay attention.
The tolerated limit of alcohol is 0.50g/L in blood, being above this limit is thus illegal and can entitle you an expensive fine and license withdraw and maybe also a night in jail. Also driving after having taking drugs is illegal.All passengers are required to wear their seat belt and children under 10 must use the back seat.
