Query: What's the speed limit on the A6 motorway?
The speed limit for most of the length of A6 is default 90 km/h (outside city limits). The section from Kaunas to Jonava has been upgraded to a dual carriageway with at-grade junctions and traffic-lights. The remaining sections are roads with one lane in each direction, leading through towns like Ukmergė, Utena and Zarasai.
In 1965, the first known experiments with variable speed limit signs took place on a 30 km stretch of German motorway A8 between Munich and the border city of Salzburg, Austria. Mechanically variable message signs could display speeds of 60, 80 and 100 km/h, "danger zone" or "accident". Personnel monitored traffic using video technology, and manually controlled the signage. Beginning in the 1970s, additional advanced traffic control systems were put into service. Modern motorway control systems can work without human intervention using various types of sensors to measure traffic flow and weather conditions. In 2009, of German motorways were equipped with such systems.
Vehicles with a top speed less than (such as quads, low-end microcars, and agricultural/construction equipment) are not allowed to use the autobahn, nor are motorcycles and scooters with low engine capacity regardless of top speed (mainly applicable to mopeds which are typically limited to or anyway). To comply with this limit, heavy-duty trucks in Germany (e.g. mobile cranes, tank transporters etc.) often have a maximum design speed of (usually denoted by a round black-on-white sign with "62" on it), along with flashing orange beacons to warn approaching cars that they are travelling slowly. There is no general minimum speed but drivers are not allowed to drive at an unnecessarily low speed as this would lead to significant traffic disturbance and an increased collision risk.
Top speeds are in practice limited by the longest straight at the track and by the need to balance the car's aerodynamic configuration between high straight line speed (low aerodynamic drag) and high cornering speed (high downforce) to achieve the fastest lap time. During the 2006 season, the top speeds of Formula 1 cars were a little over 300 km/h (185 mph) at high-downforce tracks such as Albert Park, Australia and Sepang, Malaysia. These speeds were down by some from the 2005 speeds, and from the 2004 speeds, due to the recent performance restrictions (see below). On low-downforce circuits greater top speeds were registered: at Gilles-Villeneuve (Canada) 325 km/h (203 mph), at Indianapolis (USA) 335 km/h (210 mph), and at Monza (Italy) 360 km/h (225 mph). In testing one month prior to the 2005 Italian Grand Prix, Juan Pablo Montoya of the McLaren-Mercedes F1 team recorded a record top speed of 372.6 km/h (231.5 mph), which got officially recognised by the FIA as the fastest speed ever achieved by an F1 car, even though it was not set during an officially sanctioned session during a race weekend. In the 2005 Italian GP Kimi Räikkönen of McLaren-Mercedes was recorded at 370.1 km/h (229.9 mph). This record was broken at the 2016 Mexican Grand Prix by Williams driver Valtteri Bottas, whose top speed in race conditions was 372.54 km/h (231.48 mph). However, even though this information was shown in FIA's official monitors, the FIA is yet to accept it as an official record. Bottas had previously set an even higher record top speed during qualifying for the 2016 European Grand Prix, recording a speed of 378.035 km/h (234.9 mph), albeit through the use of slipstream drafting. This top speed is yet to be confirmed by any official method as currently the only source of this information is the Williams team's Twitter post, while the FIA's official speed trap data measured Bottas's speed at 366.1 kmh in that instance. At the moment Montoya's speed of 372.6 kmh (231.5 mph) is still regarded as the official record, even though it was not set during a sanctioned session.
Typical travel times in minutes by road "(peak times in italics)" are: central London 75 "(110)", Birmingham 45 "(60)", Manchester 120 "(175)", Leicester 50 "(65)", Oxford 50 "(60)", Cambridge 85 "(130)", Milton Keynes 20 "(30)". Travel times (peak) by rail (from April 2008) by West Midlands Trains - as well as Virgin Trains services in minutes are: from Northampton to Central London (Euston) 55, to Birmingham 65; from Milton Keynes to Central London 40 and Manchester 120. Airports at Heathrow, Gatwick, and Stansted as well as Birmingham Airport, Luton and East Midlands are all within easy reach. The village has bus services to Northampton, Towcester and Milton Keynes, though this is poor on Sundays and weekday evenings.
If all these motorways are opened, Ireland will have a ratio of 1 km of motorway to every 4,277.56 people (assuming a population of 4.5 million) by 2015. This compares to a current ratio of 1 km of motorway to every 6,017.32 people in Belgium. Although welcomed by many people, the construction of new motorways in Ireland has not been without controversy or opposition. In particular, the construction of the M3 motorway through the archaeologically significant Tara-Skryne valley (or Gabhra) near Tara has led to protests and calls for protection of its landscape from many, including Pat Wallace, Director of the National Museum of Ireland, and other prominent figures in Ireland and other countries. The Smithsonian Institution in the US has placed the Hill of Tara archaeological complex on its list of endangered cultural treasures as a result of the M3's construction.
In 1973, in the wake of the 1973 oil crisis, a federal speed limit of 100 km/h (62 mph) on Autobahns was imposed to help conserve fuel for fear of impending future shortages (not for environmental or safety reasons). The measure only lasted from December 1973 to March 1974; while the administration and the Bundestag were in favor of keeping the speed limit, the Bundesrat pushed to repeal the law. As a compromise, a "recommended speed" was introduced on Autobahns and "highways outside of built-up areas with a center divide or without a center divide and a continuous lane for overtaking in both directions". This law is basically still in effect today. Unrestricted non-Autobahn highways, however, have since become virtually non-existent or replaced by "Schnellstraßen", Autobahn-like expressways typically limited to 120 or 130 km/h and normally only covering a few kilometers.
Several A roads pass through the city. The A449 road runs south-west to Malvern and north to Kidderminster. The A44 runs south-east to Evesham and west to Leominster and Aberystwyth and crosses Worcester Bridge. The A38 trunk road runs south to Tewkesbury and Gloucester and north-north-east to Droitwich and Bromsgrove and Birmingham. The A4103 goes west-south-west to Hereford. The A422 heads east to Alcester, branching from the A44 a mile east of the M5. The city is encompassed by a partial ring road (A4440) which is formed, rather inconsistently, by single and dual carriageways. The A4440 road provides a second road bridge across the Severn (Carrington Bridge) just west of the A4440-A38 junction. Carrington Bridge links the A38 from Worcester towards Gloucester with the A449 linking Worcester with Malvern.
General speed limits in Germany are set by the federal government. All limits are multiples of 5 km/h. There are two default speed limits: 50 km/h (31 mph) inside built-up areas and 100 km/h (62 mph) outside built-up areas. While parts of the autobahns and many other freeway-style highways have posted limits up to 130 km/h (81 mph) 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 which may be rendered in English:
Any person driving a vehicle may only drive so fast that the car is under control. Speeds must be adapted to the road, traffic, visibility and weather conditions as well as the personal skills and characteristics of the vehicle and load.
This requirement applies to all roads, and is similar to the "reasonable speed" legal obligation levied in other nations.
A 2008 estimate reported that 52% of the autobahn network had only the advisory speed limit, 15% had temporary speed limits due to weather or traffic conditions, and 33% had permanent speed limits. Measurements from the German State of Brandenburg in 2006 showed average speeds of on a 6-lane section of autobahn in free-flowing conditions.
The minimum driving age in the United Kingdom is 16 for mopeds under , and 17 for cars and motorcycles. Access to motorcycles producing more than is restricted to riders with two years experience or aged 21. The British Overseas Territories and the British Crown dependencies issue their own driving licences. There is no legal requirement for a non-professional driver to carry a driving licence in the UK whilst driving, although it must be produced at a police station within seven days, if required to do so by a police officer.
Open-wheeled racing is among the fastest in the world. Formula 1 cars can reach speeds in excess of . At Autodromo Nazionale Monza, Antônio Pizzonia of BMW Williams F1 team recorded a top speed of in the 2004 Italian Grand Prix. Since the end of the V10 era in 2006 speeds like this have not been reached, with contemporary machinery reaching around . It is difficult to give precise figures for the absolute top speeds of Formula 1 cars, as the cars do not have speedometers as such and the data are not generally released by teams. The 'speed traps' on fast circuits such as Monza give a good indication, but are not necessarily located at the point on the track where the car is travelling at its fastest. BAR Honda team recorded an average top speed of in 2006 at Bonneville Salt Flats with unofficial top speed reaching using modified BAR 007 Formula 1 car. Speeds on ovals can range in constant excess of , and at Indianapolis in excess of . Some sources claim that in 1996, Paul Tracy recorded a trap speed of at Michigan International Speedway. In 2000, Gil de Ferran set the one-lap qualifying record of at California Speedway. Even on tight non-oval street circuits such as the Grand Prix of Toronto, open-wheel Indy Cars attain speeds of .
Historically Silverstone has suffered traffic congestion on race days. This problem has been largely eliminated with the completion of the A43 Silverstone bypass, a dual-carriageway road just to the north of the circuit. When the race was moved to an April date in 2000, rainy conditions turned the fields used for car parking into mud baths, causing chaos for spectators trying to park. On F1 race day in 1999 there were some 4200 helicopter journeys made to Silverstone Heliport, which was the busiest airport in the UK on that day.
To facilitate this development (and wider national infrastructure needs for outer orbital routes around London), two major projects are underway or planned. Work has begun to extend East West Rail from Bicester to the West Coast Main Line at (Milton Keynes); onward extension to Cambridge is planned. Concurrently, detailed route options planning has begun on the Oxford-Milton Keynes phase that is to complete the Oxford-Cambridge Expressway (linking the A34 with the A14).
In 2011, the Department for Transport confirmed that ministers were studying a proposal for a 180 mph line between London Heathrow and Gatwick Airports. The journey would take 15 minutes and provide the first direct rail link between the two airports. The plan could virtually make Heathrow and Gatwick into a single hub. In 2018 a proposal was put forward by a British engineering consultancy, Expedition Engineering, for HS4Air, a high-speed railway line that would run to the south of Greater London, creating a 140km link between HS2 and HS1 via Heathrow and Gatwick Airports.
One distinguishing characteristic between German "Bundesstraßen" and "Autobahnen" is that there usually is a general 100 km/h (62 mph) speed limit on federal highways out of built-up areas, as opposed to the merely advisory speed limit ("Richtgeschwindigkeit") of 130 km/h (83 mph) in unmarked sections of the autobahns. However, a number of "Bundesstraßen" have been extended as expressways (dual carriageways) (colloquially called "Yellow Autobahns"). Many of these have speed limits of usually 100–120 km/h, others have only an advisory speed limit like autobahns. Most sections of the federal highways are only single carriageway with one lane for each direction and no hard shoulder pull-out area.
"Gran Turismo 6" was announced on May 15, 2013, when Sony Computer Entertainment Europe hosted a celebration of the 15th anniversary of Gran Turismo at Silverstone Circuit in the United Kingdom. Kazunori Yamauchi said at the official announcement, "Gran Turismo 6" will feature 71 layouts of 33 tracks, 1200 cars, a new flexible rendering engine that features adaptive tessellation, and a redesigned simpler menu interface with faster loading times. An early build of Gran Turismo 6's updated physics was shown to the public when GT Academy 2013 was released on the PlayStation Store on July 2, 2013.
On July 10, 2013, game developers announced that the Goodwood Festival of Speed hill climb course will be included on the game. The 1.16 mile strip of road that runs through the Earl of March's family home's grounds hosts the annual Festival of Speed and current Formula One, Moto GP, World Rally Championship cars and racers as well as other famous drivers and cars from all ages and aspects of motor sport. This gave the game developers the idea to base a track here due to the wide variety of vehicles that use the hill climb in front of 185,000 spectators. Yamauchi said "I have always been a huge admirer of the Festival of Speed and what Lord March has achieved, I love the incredible range of cars on display – from the priceless, rare and exotic, to the latest family hatchback and full on racing cars – I love the challenge of the Hill Climb and the rally stage. Goodwood represents every type of motoring and motor sport which very much mirrors what we aim to achieve with Gran Turismo and so it is very special that we have forged this partnership. There will be no better feedback than that provided by the Goodwood fans to tell me if we are heading in the right direction with "Gran Turismo 6"!" A demo of GT6 was made available at the Festival, to give spectators the chance to challenge Nick Heidfeld's 41.6-second course record set in 1999 in a Formula 1 car.
The GTA also consists number of King's Highways and supplemented by municipal expressways. One of the most principal highways in the GTA, Highway 401, is also the longest in Ontario and is also one of the busiest highways in the world. Notably, a segment of the highway passing through the GTA holds the distinction of being North America's busiest highway. The GTA is laced with a number of limited-access highways, including the 400-series highways. These include:
Highway 2 has a wide range of traffic levels along its length. At the south end, the highway is a lightly travelled two lane road from the United States border to Fort Macleod. It then doubles to four lanes and volume progressively increases until De Winton north of Okotoks, but remains relatively light. Within Calgary, volume climbs exponentially on Deerfoot Trail through the southern suburbs of the city reaching nearly 170,000 vehicles per day at Memorial Drive near downtown, making that stretch of Highway 2 the busiest roadway in western Canada. Volume swiftly drops north of Beddington Trail in Calgary, but remains moderate on the Queen Elizabeth II Highway until Edmonton where it again increases to nearly 95,000 vehicles per day in the vicinity of Ellerslie Road. Whitemud Drive, Anthony Henday Drive, Yellowhead Trail, and St. Albert Trail are all busy expressways carrying large volumes of local traffic, especially at peak hours. North of St. Albert the drop in traffic is brisk, increasingly so after Morinville where the highway is no longer divided. Volume remains very light through most of the Peace Country before briefly exceeding 20,000 vehicles per day near the northern terminus in Grande Prairie.
The business and bypass cross Route 102 soon after splitting. The western half of the bypass is a two-lane limited access road, with one grade separation — under Gleaner Chapel Road — and one intersection — at Route 102. This newer section ends as it merges with Route 101, once the Rhode Island and Connecticut Turnpike, and now called Hartford Pike. The two parallel alignments cross the Scituate Reservoir and Route 116 before they merge near the east edge of Scituate. This merge was the east end of the Foster and Scituate Turnpike, and was the east end of Route 101 until the early 2000s (when it was truncated to the merge with US 6 Byp.). The Rhode Island and Connecticut Turnpike continued to the Olneyville section of Providence, where it is known as Hartford Avenue.
U.S. Route 6A (US 6A) is an alternate route of US 6 in Rhode Island. The route begins at US 6 and I-295 in Johnston and follows Hartford Avenue through the city. US 6A continues into Providence, traveling along Hartford Avenue to its terminus at US 6.
The 1964 British Grand Prix was a Formula One motor race held at Brands Hatch on 11 July 1964. The event was also designated as the European Grand Prix. It was race 5 of 10 in both the 1964 World Championship of Drivers and the 1964 International Cup for Formula One Manufacturers. The first of twelve British Grands Prix to be held at the southern England circuit, it would alternate with Silverstone until 1987. The race was won by Jim Clark driving a Lotus 25.
The route of the A2 motorway is shared with two major European routes. Between its start, at Amstel Interchange, near Amsterdam, and the Interchange Oudenrijn, near Utrecht, European route E35 follows the A2 motorway. From the Oudenrijn Interchange towards the Belgian border just south of Maastricht, European route E25 follows the route of the A2. Local and express lanes on A2 have different speed limits. The speed limit on express lanes is 120 km/h (75 mph) and locals is 100 km/h (63 mph).
Out of localities, the speed limits for categories A and B (motorcycles and automobiles) are: 130 km/h on motorways, 100 km/h on expressways and E-roads, and 90 km/h on other roads. For categories C, D, and D1 (trucks and buses), the limits are: 100, 80, and 70 km/h respectively, and for categories A1, B1, and C1 (low weight/power motorcycles and automobiles) they are: 80, 70 and 60 km/h respectively. Tractors and mopeds have a maximum speed limit of 35 km/h both in and out of localities, and are not allowed on motorways.
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.
Historically, maximum speed limit in Georgia was 90 km/h as there were no motorways in the country. With the change of government in 2004 and activation of country's economy, the construction of first motorway started. The motorway forms the one of the main transit routes of the country – S1/E60. Currently, the motorway part of the route spans from north exit of Tbilisi to Zemo Osiauri, a small village near Khashuri.
