Query: What's the speed limit on the A6 motorway?
General speed limits in Germany are set by the federal government. All limits are multiples of 5km/h. There are two default speed limits: 50km/h (31mph) inside built-up areas and 100km/h (62mph) outside built-up areas. While parts of the autobahns and many other freeway-style highways have posted limits up to 130km/h (81mph) based on accident experience, congestion and other factors, many rural sections have no general speed limit. The German Highway Code (Straßenverkehrsordnung) section on speed begins with the requirement [1] which may be rendered in English:
Different default speed limits apply to particular categories of roads. Default speed limits are termed as "ordinary speed limits" by the Road Traffic Act 2004. There are also speed restrictions for certain classes of vehicles. As of 2007, the ordinary speed limits are as follows:There are particular powers available to local county councils under the "Road Traffic Act 2004" to apply "special speed limits" to particular stretches of road. Special speed limits of 30, 50, 60, 80, 100 and 120 km/h (19, 31, 37, 50, 62 and 75 mph) can be imposed, but only 30 and 60 km/h (19 and 37 mph) are exclusively "special" as opposed to the others which are "ordinary". The limit is ordinary for motorways but can be special for dual carriageways forming part of a national primary road. Special speed limits are usually lower than normal, for schools, etc. One instance of higher speed limits being applied is that of the new N2 route from the M50 motorway in Fingal (Dublin) to north of Ashbourne, County Meath where a special speed limit of 120 km/h (75 mph) was imposed from 15 June 2006, therefore becoming the first non-motorway road in Ireland to obtain this speed limit. According to the project engineers, the National Roads Authority decided due to the lack of available space at the M50 junction to accommodate a parallel joining non-motorway route that they would designate the new road as high quality dual carriageway and block off the existing road from the M50. The 2004 Act has therefore allowed Local Authorities to get around such issues as the implications of motorway restrictions on learner drivers as under this act such drivers are now permitted to travel at speeds up to on such roads as this section of the N2. The N1 dual carriageway north of Dundalk has also recently been granted a special speed limit of , in line with its preceding M1 motorway. As of 2 March 2007, Cork County Council and Limerick city and county councils have published amendments to local bye-laws to adjust several High Quality Carriageways' speed limits to . S.I. No. 331 of 2012 allowed a new speed limit of 40km/h to be applied by a city or county council.
110 km/h and 120 km/h are the main speed limits on motorways. 120 km/h (75 mph) is only set on the best, safest and straightest motorways, usually the newest, which mostly are present in the southern parts of Sweden on the E4 and E6, in total about 300 km out of the 1500 total motorway km. 110 km/h is still the most common speed limit on motorways in Sweden.
On all non-urban roads and motorways, school buses and vehicles containing contaminant, explosive or flammable materials must decrease their speed limit by 10 km/h.On motorways, a minimum speed of 60 km/h is mandatory for all kinds of vehicles. Minimum speeds in the rest of roads are one half of the generic speed limit for every vehicle. If a posted speed limit sign is below this value, the minimum speed is the posted limit minus 10 km/h.
In July 1967, Castle announced that was to become the permanent maximum speed limit for all roads and motorways. She had accepted RRL evidence that the speed limit had reduced the number of casualties on motorways. She ruled out minimum speed limits for motorways which would also reduce the danger of slow traffic as being too difficult to enforce and likely to increase congestion off the motorways.
The A6 motorway runs near a number of Croatian cities, provides access to Risnjak National Park and indirectly to numerous resorts, notably in the Istria and Kvarner Gulf regions. The motorway route was completed in 2008. The motorway is nationally significant because of its positive economic impact on the cities and towns it connects, and because of its contribution to tourism in Croatia. The importance of the motorway as a transit route will be further increased upon completion of a proposed expansion of the Port of Rijeka and Rijeka transport node.
The motorway consists of two traffic lanes and an emergency lane in each driving direction separated by a central reservation. Sections of the motorway that have a gradient greater than 4% are divided into three lanes to prevent traffic problems caused by slower vehicles. These sections have no emergency lanes. Similarly, there are no emergency lanes in the tunnels. All intersections of the A6 motorway are grade separated. As the route traverses rugged mountains it requires numerous long bridges, viaducts, tunnels, and other structures. As of 2010 there are nine exits and three rest areas situated along the route. The majority of the motorway is a ticket system toll road with pricing tied to vehicle classification. Each exit between Grobnik mainline toll plaza and Bosiljevo 2 interchange has a toll plaza. No toll is charged at Bosiljevo 2 where the traffic switches to the A1 motorway; traffic is tolled upon leaving the A1 motorway. Exits between the mainline toll plaza and Orehovica interchange have no toll plazas, as that part of the A6 route is not tolled.
As the A6 motorway route runs through mountainous terrain of Gorski Kotar, it comprises a substantial number of major structures—bridges, viaducts, tunnels, underpasses, flyovers, and culverts. Out of the total length of the Rijeka–Zagreb motorway of , are situated within such structures. The northern part of the Rijeka–Zagreb motorway, designated as the A1 motorway, comprising between Zagreb and Karlovac, contains only of such structures as the section is situated in a plain. The between Karlovac and Bosiljevo 2 interchanges, contains as much as of the structures. Thus the A6 motorway has , or 21% of the route, located within such structures. The Rijeka–Zagreb motorway has a total of 24 viaducts, 13 tunnels, 5 bridges, 45 underpasses, and 26 flyovers. All of the bridges, viaducts, and tunnels on the A6 motorway have at least two driving lanes in each direction.
The longest tunnel on the A6 motorway route is the Tuhobić Tunnel, located on the Oštrovica–Vrata section. The tunnel was initially opened as a single-tube tunnel in 1996. The second tunnel tube was excavated in August 2007 and opened to traffic in 2008. The European Tunnel Assessment Programme (EuroTAP), a tunnel safety assessment programme supported by the European Commission, coordinated by FIA and led by the German motoring club ADAC, tested Tuhobić Tunnel twice—once in 2004, when it achieved poor results, and again in 2009 after implementation of EuroTAP safety recommendations. The 2009 test ranked the tunnel as the second safest in Europe. An unusual feature associated with the A6 tunnels is the close proximity of the Javorova Kosa and the Podvugleš tunnels—they are separated by less than of road. In order to prevent abrupt changes in road conditions caused by the weather, the distance between the tunnels is covered by translucent roofing. The tunnels are located on the Vrbovsko–Ravna Gora section. Other significant tunnels on the A6 motorway are the Veliki Gložac and Vrata tunnels. While the former, as with all the other tunnels mentioned, is significant due to its length, the latter is notable for the large cavern encountered during its excavation.
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 for motorways outside of settlements, whereas on regular roads within a settlement the speed limit is . 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.
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 130 km/h (81 mph) on motorways ("autosnelwegen"). On September 1, 2012, the motorway default speed limit was raised from 120 km/h (75 mph) to 130 km/h (81 mph) 
, but it applies to only 48% of all motorways with the intent of 60% of motorways.
The A6 motorway () is a motorway in Croatia spanning . It connects the nation's capital, Zagreb, via the A1, to the seaport of Rijeka. The motorway forms a major north–south transportation corridor in Croatia and is a part of European route E65 Nagykanizsa–Zagreb–Rijeka–Zadar–Split–Dubrovnik–Podgorica. The A6 motorway route also follows Pan-European corridor Vb.
Historically the motorway speed limits were 90 km/h before 2000 (there were not many of them and most had dense traffic). The motorway speed limits was raised to 100 km/h for less densely trafficked motorways in 2000, and to 110 km/h in 2014.
Variable speed limits with the hard shoulder operating as it would on a conventional motorway. They have most often been installed where a motorway has previously been widened but with a discontinuous hard shoulder to incorporate existing bridges, therefore using the hard shoulder as a running lane is ruled out. Existing gantries are upgraded to support signals capable of displaying a mandatory speed limit and speed cameras.Variable speed limits with the hard shoulder selectively opened as a running lane during periods when there is a lower speed limit in force.
Variable speed limits with the hard-shoulder removed and converted to a permanent running lane.
Local exceptions to motorway speed limits may apply, mainly near cities and on inner-city motorways. One of the lowest speed limits on a Swedish inner-city motorway is 70 km/h (43 mph). This has been set on E4 Essingeleden through Stockholm. This is an 8-lane motorway passing near central parts of the capital. It is also present through Gothenburg. However this speed limit only applies on a short part of the motorways. The reason is the high risk of jams.
Dobra Bridge is located between the Vrbovsko and Ravna Gora interchanges of the A6 motorway in Gorski Kotar, Croatia, spanning Dobra River. It is long and carries the motorway across five spans. The bridge consists of two parallel structures, both completed in 2003 by Primorje. The bridge is tolled within the A6 motorway ticket system and there are no separate toll plazas associated with use of the bridge. The bridge is located in a water protection area.
The speed limit on motorways is generally 110 or 120 km/h (68 or 75 mph). Speed limits of 70 and 90 km/h are often used on urban motorways, and electronic signs can show a lower limit in bad weather.
The primary high-speed motorways are called autoceste (; singular: "autocesta"), and they are defined as roads with at least three lanes in each direction (including hard shoulder) and a speed limit of not less than . They are marked with a special road sign, similar to the road sign depicting a motorway/autoroute/autobahn in other parts of Europe. In Croatia this sign has green background. The national speed limit on an "autocesta", effective in case no other speed limits are present, is , with a legal tolerance of 10% on speeds over 100 km/h (as of 2009). The Croatian motorway (autocesta) network is long.
The A6 is a Swiss motorway. Up until the mid-1990s it was called N6. This denomination is still used in certain documents. The A6 has two sections. the first section starts in Biel / Bienne and goes to Schönbühl. This section is a cantonal road belonging to the canton of Berne, but in 2014 it will be taken over by the Swiss federation and thus turn into a national road. In Schönbühl the A6 joins the A1. A few kilometers south, at the junction Bern-Wankdorf, the two motorways separate again. The A6 leads up the Aare valley to Thun, and from there to the junction of Lattigen near Spiez. At this junction, the A6 turns west to Wimmis while the motorway going south changes into the A8. It ends right after the Simmenfluh-Tunnel where the road turns into a cantonal road. Earlier, there had been plans to continue the national road through the Simmental and then connect it with the Canton of Valais through the Rawil-Tunnel, but this project was abandoned in 1984. The road and the tunnel were never built.
The A6 motorway, an Autobahn in Switzerland, connects Biel / Bienne over Bern with Thun. The A6 is located entirely within the Canton of Berne and, in particular, has a great regional significance, as only the section of Bern in the direction Berner Oberland is part of the Swiss national road system.
The A6 motorway is a motorway in the Netherlands. It is just over 100 kilometers in length and it connects the A1 motorway at interchange Muiderberg with the A7 motorway at interchange Joure.
The A6 motorway is a significant north–south motorway in Croatia connecting the largest seaport of the country, Rijeka, to its hinterland and to the rest of the Croatian motorway network via the A1 motorway Bosiljevo 2 interchange. The motorway follows a route through the Gorski Kotar region. Part of the road network of Croatia, the motorway is also part of European route E65 Nagykanizsa–Zagreb–Rijeka–Zadar–Split–Dubrovnik–Podgorica. The motorway is of major importance to Croatia in terms of development of the economy; it is especially important for tourism and as a transit transport route. The road serves tourist resorts in Istria and the Kvarner Gulf islands. Because of the link formed between Zagreb and Rijeka, tourism-related traffic originating from the countries neighbouring Croatia to the north flows via this road to the Adriatic coast on the south. The road also serves tourists originating in the northern inland areas of Croatia. The A6 route predominantly follows an east–west orientation, but the motorway is locally regarded as a north–south communication. The ultimate importance of the motorway as a transit route shall be achieved upon completion of the proposed expansion of Port of Rijeka and the Rijeka transport node. The expansion is planned to encompass an enhancement of the cargo handling capacity of the Port of Rijeka; improved railroad links; and a new Rijeka bypass motorway linking the A6, via a new interchange, with the present routes of the A7 and A8 motorways. One of the aims of the project is to increase traffic along the A6 route. As of the June 1997 Pan-European Transport Conference in Helsinki, the motorway is a part of the Pan-European corridor Vb.
German autobahns are famous for having no universal motorway speed limit, although slightly more than 50% of them have posted speed limits[14] and about 10% are equipped with motorway control systems that can show variable speed limits.[15] There is no national speed limit, either, for cars and motorcycles on any highway outside of towns if it has a central reservation or a minimum of two marked lanes per direction. Due to this it is common to be overtaken by cars or motorcycles travelling over 200km/h (125mph). On such roads, as well as motorways, a recommended speed limit (Richtgeschwindigkeit) of 130km/h (81mph) applies. While driving at higher speeds is not punishable, the increased risk induced by higher speeds (erhöhte Betriebsgefahr) may result in partial liability for damages. Moreover, the law forbids travel at speeds that would extend the vehicle's minimum halting distance beyond the driver's line of sight.[16] On all German roads, there are speed limits for trucks, buses, cars towing trailers, and small motorised vehicles (Mopeds, etc.).
In 1966, at the end of the 4-month trial of a blanket speed limit on previously unrestricted roads and motorways, speed checks on the M6 in Cheshire suggested that although cars were actually being driven about faster, they were still usually travelling at speeds below the new limit. The crash rate was lower on the M6 in Staffordshire (the better weather was noted too) and continued to fall on the M5 in Worcestershire as it had before the new limit was imposed, and there was no change in the crash rate on the M6 in Cheshire or on the M1 in Northamptonshire.
Although these 70mph speed limit road signs are normally not used on motorways (the National Speed Limit road sign is normally used, as it makes it more understandable for motorists their maximum speed on the type of vehicle they're using), they have been used on non-motorway special roads within the UK, and across the motorways within Scotland. 
According to ESTC, German motorways without a speed limit, but with a speed recommendation, are three times more deadly than motorways with a speed limit.
South of Gävle, the road becomes an almost continuous motorway, with the only non-motorway part being a long section past Ljungby, currently a 2+1 limited-access road. Upgrade to motorway standard will start in 2018. With the exception of the Ljungby bypass, the final stretch of the motorway to be opened was the road between Uppsala and Mehedeby, which was inaugurated on October 17, 2007. South of Gävle, the speed limit is on 60% and on 30% of the road. North of Gävle there are varying speed limits, with , and as the most common. The speed limits on the main roads in Sweden were changed on many stretches in October 2008, which saw the introduction of the 120 km/h limit.
Construction of the motorway began in 1996. Part of the motorway was opened along with the Eleftherios Venizelos International Airport to which it connects, in 2001. It started from the Gerakas interchange and led to the airport.
In September 2002, construction of the high-speed Proastiakos railway was begun, in the large median of the motorway. The railway was opened in 2004. In early 2003, the A6 was opened from the Kifisias Avenue Interchange to Eleftherios Venizelos Airport. In November 2003, the western part opened from the junction with the A8 to Kifisias Avenue.
