European route E6 is the main north-south thoroughfare through Norway as well as the west coast of Sweden. It is 3,056 km (1,899 mi) long and runs from the southern tip of Sweden at Trelleborg, into Norway and through almost all of the country north to the Arctic Circle and Nordkapp. The route ends in Kirkenes close to the Russian border.
A limited-access road, known by various terms worldwide, including limited-access highway, dual-carriageway, expressway, and partial controlled-access highway, is a highway or arterial road for high-speed traffic which has many or most characteristics of a controlled-access highway, including limited or no access to adjacent property, some degree of separation of opposing traffic flow, use of grade separated interchanges to some extent, prohibition of slow modes of transport, such as bicycles, (draught) horses, or self-propelled agricultural machines; and very few or no intersecting cross-streets or level crossings. The degree of isolation from local traffic allowed varies between countries and regions. The precise definition of these terms varies by jurisdiction.
The Autostrade are roads forming the Italian national system of motorways. The total length of the system is about 7,016 kilometres (4,360 mi), as of 30 July 2022. In North and Central Italy, the Autostrade mainly consists of tollways managed by Autostrade per l'Italia, a holding company controlled by Cassa Depositi e Prestiti. Other operators include ASTM, ATP, and Autostrade Lombarde in the north-west; Autostrada del Brennero, A4 Holding, Concessioni Autostradali Venete, and Autovie Venete in the north-east; Strada dei Parchi, SALT, SAT, and Autocisa in the center; and CAS in the south.
The registration plates of cars in Norway are maintained by the Norwegian Ministry of Transport and Communications. As in most countries, cars are identified only by number plates read visually. Each plate is a legal document that both identifies the vehicle and permits its use, and shall be returned to the registration authority when the vehicle is no longer in use.
Road speed limits in Ireland apply on all public roads in the state. These are signposted and legislated for in kilometres per hour. Speed limits are demarcated by regulatory road signs. These consist of white circular signs with a red outline. Speed limits are marked in black with "km/h" below the speed limit. Smaller "repeater" speed limit signs are used along stretches of road where there is no change in speed limit, in order to remind motorists currently on the road and to inform traffic merging from junctions that a certain speed limit applies.
Speed limits in Australia range from 5 km/h (3.1 mph) shared zones to 130 km/h (81 mph). Speed limit signage is in km/h since metrication on 1 July 1974. All speed limits are multiples of 10 km/h – the last digit in all speed signs is zero. Speed limits are set by state and territory legislation albeit with co-ordination and discussion between governments.
Road signs in Norway are regulated by the Norwegian Public Roads Administration, Statens vegvesen.
Norwegian driving licences adhere to a standard set in the European Economic Area.
A speed limit is the limit of speed allowed by law for road vehicles, usually the maximum speed allowed. Occasionally, there is a minimum speed limit. Advisory speed limits also exist, which are recommended but not mandatory speeds. Speed limits are commonly set by the legislative bodies of national or local governments.
Speed limits in the Czech Republic vary depending on the type of road, and whether the road is within a settlement or not. The top speed limit is 130 km/h (81 mph) for motorways outside of settlements, whereas on regular roads within a settlement the speed limit is 50 km/h (31 mph). outside of the settlement and other than motorway the speed limit is 90 km/h. Various other special restrictions are applied for certain types and weight categories of vehicle.
Denmark has three general speed limits:
Sweden has speed limits ranging from 30 km/h to 120 km/h, where 30, 40, 50, 60 and 70 km/h are used within towns and cities. Outside schools and hospitals the limit is often 30 km/h. 70, 80, 90 and 100 km/h are mainly used outside built-up areas where the speed limit depends on the standard and safety of the road. 90 and 100 km/h are used mainly on roads with separated lanes, however local exceptions may apply, mainly in northern Sweden, where 100 km/h (62 mph) is legal on roads with no separated lanes and where the standard of the road often is poor. The main reason for setting 100 km/h on these roads is because of their high importance to the region. Earlier it was permitted to drive 110 km/h (68 mph) on these roads but due to the poor standards the speed limit was lowered to 100 km/h in 2008.
The speed limit in localities is set at 50 km/h, but the owner of the road can apply for permission to raise it up to 90 km/h for automobiles and motorcycles or decrease it as low as 30 km/h for tramways and 40 km/h for automobiles. It is because of this that some city boulevards have a speed limit of 60 km/h, and some National Road stretches that pass through villages have a speed limit of 70 km/h.
Spain has different speed limits for every kind of road and vehicle. Until 1973, there were no speed limits on Spanish motorways, a generic limit of 130 km/h was instated then in order to save fuel during the 1973 energy crisis. It was lowered to 100 km/h to prevent accidents, but it was raised again in 1992, this time to 120 km/h. There have been proposals to raise the speed limit to 130 km/h, but have been rejected so far.
The default speed limits in the Netherlands are 50 km/h (31 mph) inside built-up areas, 80 km/h (50 mph) outside built-up areas, 100 km/h (62 mph) on expressways (autowegen), and, as of 16 March 2020, 100 km/h from 6:00 to 19:00 and 130 km/h from 19:00 to 6:00 on motorways (autosnelwegen).
General speed limits in New Zealand are set by the New Zealand government. The speed limit in each location is indicated on a nearby traffic sign or by the presence of street lighting. The limits have been posted in kilometres per hour (km/h) since 1974. Before then, when New Zealand used imperial units, maximum speeds were displayed in miles per hour (mph). Today, limits range from 10 km/h (6.2 mph) to 110 km/h (68 mph); in urban areas the default speed limit is 50 km/h (31 mph).
Road signs in Switzerland and Liechtenstein generally conform to the 1968 Vienna Convention on Road Signs and Signals.
Four general speed limits apply on roads in Serbia:
Speed limits in Thailand are a set of maximum speeds applicable on any road in Thailand. For small cars that weigh less than 1,200 kg (2,646 lb), the maximum limits within the built-up area and outside are 80 km/h (50 mph) and 90 km/h (56 mph) respectively. The exception applies to motorways, in which small cars can use up to 120 km/h (75 mph). Heavier cars, buses and trailer have more restrictive limits. Despite having the general maximum speed limits, the limits may be altered by a roadside sign.
