Strade extraurbane principali


The strade extraurbane principali or type B road, better known as a "superstrada", are a type of roads of Italy defined within the Italian Highway Code.

Characteristics

Therefore, compared to motorways, roads of this type have some technical differences, the color of the signs, the speed limit for cars and motorcycles, the radius of curvature, the presence of the emergency lane and the presence of SOS columns. For transit on main extra-urban roads, unlike many motorways, there is currently no toll system, except for the Pedemontana Veneta.

Transit restrictions

The circulation of the following vehicles on the autostrade and roads referred to in paragraph 1 is prohibited:
  • cycles, scooters, mopeds, motorcycles with a displacement of less than if with a combustion engine, or with a power of less than if with an electric motor, and motorbikes with a displacement of less than if with a combustion engine;
  • other motor vehicles with an unladen mass of up to or a total mass of up to, with the exception of tricycles, with a displacement of not less than if with a combustion engine and in any case with a power of not less than, intended for the transport of people and with a maximum of one passenger in addition to the driver;
  • vehicles not equipped with tyres;
  • agricultural machines and operating machines;
  • vehicles with disorganized loads that are not solidly secured or which protrude beyond the permitted limits;
  • non-watertight vehicles with uncovered cargo, if they transport materials susceptible to dispersion;
  • vehicles whose load or dimensions exceed the limits set by articles 61 and 62, with the exception of the cases provided for by art. 10;
  • vehicles whose conditions of use, equipment and tires may constitute a danger to traffic;
  • vehicles with cargo not properly positioned and secured.
The movement of pedestrians and animals is prohibited, except for service areas and rest areas. In these areas animals can circulate only if duly guarded. Pedestrians are only allowed to pass along the emergency lanes to reach the emergency call points. On carriageways, ramps, junctions, service or parking areas and in any other motorway area it is prohibited:
  • tow vehicles other than trailers;
  • request or grant passages.
These restrictions are the same as those that apply along Italian motorways. Roadside assistance is permitted, as along motorways, only to authorized companies. Furthermore, the circulation of pedestrians and animals is only permitted within the service areas and rest areas.

Speed limits

On strada extraurbana principale, the speed limit for cars, motorcycles and trucks with a laden mass not exceeding is, unless otherwise indicated, for buses with a laden mass between and and for trucks with a laden mass between and it is, for trucks with a higher laden mass to and for vehicles towing trailers it is. For other categories of motor vehicles, the limit is lower and depends on the type of vehicle.

Administrative classification and signage

The strade extraurbana principali do not follow a specific nomenclature; they are classified administratively as Italian state roads, Italian regional roads, Italian provincial roads or Italian municiapal roads. Therefore, some state, regional, provincial, municipal roads may have sections technically classified as strade extraurbana principali, others as strade extraurbane secondarie and still others as urban roads.
Along the strade extraurbana principali the background of the road signs are blue, therefore not different from the signs installed along the strade extraurbane secondarie.

Types of homologous roads in other countries

In other European states, what in Italy are known as the strade extraurbana principali, roads with separate carriageways with two or more lanes in each direction, without at-grade intersections, are not classified as highways, but in different ways. For example:
  • voies rapides ;
  • gelbe Autobahn ;
  • autovías ;
  • hitre ceste.
