Dual carriageway

Under a motorway-like road is defined as a road that resembles freedom by crossing and usually also by structurally separate carriageways and by their signs a highway. However, the separate carriageways are not mandatory for the official definition.

Similar motorway roads are for Germany defined in the Guidelines for signposting outside of highways, short WARC. Such a road must be of high importance for traffic and make a trip without stopping in control mode. It should ideally be provided with a motorway-like signs. In the administrative regulation for road traffic regulations can be found since the year 2009 for the first time an indication of the legislature on their identification. Accordingly, the yellow or white exit sign is placed exclusively on motorway-type roads. The implication that such a sign must be at such roads, the Regulation does not, however, to. If it is no highway within the meaning of the Road Traffic Act, while the color scheme of white text on a blue background is changed. At federal or other on local roads this is done in black and yellow, as well as on urban roads in black and white. At least any such signposted road is officially verified as road running.

In the hierarchy of road duty for transport of dangerous goods, the motorway-like roads occupy the second place after the highways. This is expressed that the legislature such roads ascribes a higher standard of safety.

There are also highways that are not motorways according to the Federal Highway Act. Among the motorway-like roads are also federal highways that are not motorways within the meaning of the Highway Code, so dedicated by the federal highway law as motorways, but are not marked as such.

The yellow signs makes clear is why used in everyday language, the term Yellow motorway, although this is also carried out on the rare white Innerortstraßen. A large majority of motorway-type roads is also shown as a dual carriageway.

In the administrative regulation for road traffic regulations can be found since 2009, two passages for signs:

  • To 333 characters exit from the highway Outside of highways, the characters only at a highway-like class roads (see point II to mark 330.1, paragraph 2 ) may be arranged. Then, the character either a yellow or - if it follows character 332 in white with objectives set out characters 432 - white base. The Scriptures and the edge are black.
  • On highway-like -maintained roads, the characters 332, 448, 449 and possibly 453 in accordance with the Guidelines for signposting outside of motorways ( RWB ), if possible.

Thus, the yellow or white exit sign may be placed only on motorway-type roads. The implication that such a sign must be at such roads, the Regulation does not, however, to.

To mark 453 additionally there is a special feature on the B6 towards Goslar and Bad Harzburg, that after the departure of the Federal Highway 395 or a yellow sign of type 453 follows. This has the reason that until 2001, the section to Bad Harzburg also belonged to the A 395, but was then demoted to the section.

Speed limits

Contrary to widespread opinion is valid on a motorway-like road is not necessarily a speed limit for cars and other motor vehicles up to a gross vehicle mass of 3.5 tonnes:

  • To a non- local motor roads without physical separation, but with at least two lanes in each direction ( that is, only a solid line between the directions of travel ) applies to cars and other motor vehicles up to 3.5 tonnes gross vehicle weight no speed limit, unless that such has been expressly arranged. Then for these vehicles, just like on the highway, only a general recommended speed of 130 km / h ( according to § 1 motorway - directional speed regulation ( BABRiGeschwV ) in conjunction with § 3 paragraph 3 No. 2.c Highway Code ). For other vehicles shall be on such roads, however, the same speed limits as they are otherwise applied to non- local roads, eg 60 km / h for trucks (in contrast to 80 km / h on motorways or at physical barrier separating, see u. ).
  • (Eg grass strips, median barrier ) shall apply to motor roads with structural separation of the lanes - regardless of the number of lanes - even for all vehicle types have the same speed limits as motorways ( § 18 para 5 Highway Code ).

If none of these two cases is true (eg, typically at 2 1 systems, see below), the otherwise usual speed limits apply (§ 3 Highway Code ).

Similar motorway roads with separated two-lane carriageways

Similar motorway roads with separated two-lane carriageways have, in some cases, such as the B 6n, no obvious difference to a highway on, except that the signs are yellow and black instead of blue and white. Reasons for this may include:

  • The development standard is well below that of a highway: smaller standard cross-section with a narrow median strip (eg B239 in Herford )
  • Tight curve radii,

Sometimes such upgraded roads are only closed for bicycles and mopeds, which allows drivers of agricultural vehicles and the intrusion by pedestrians. Some cases there are also no restrictions on vehicle traffic.

In some cases, even those roads with a motorway-like signs are provided, in which each two-lane carriageways are separated only by solid double stripes.

2 1 system

The 2 1 system has released a new high-speed variant of a crossing-free dual carriageway with separate carriageways and motorway-like ascents and descents dar. Even those roads are partially to the motorway-like signs (see above) provided. Here, the journey directions are in exchange for about 1.5 to 2 km two-lane, while the opposite direction has only one track. The carriageways are separated as strictly as in highways. Use of the oncoming lane and their entries and exits is prohibited. These roads require a total of only three tracks, but still offer a good Überholkomfort. However, the signs and road marking are extremely complicated, since each 2-1 - change must be announced on several occasions. In addition, this complex road marking must be maintained especially in the exchange area absolutely in a good state.

Since mid-2013, these roads are called highways. From this point on newly built roads of this system marked with a green colored stripes between the carriageways to better visually delineate as the roadways.

The system was created in order to create a good Überholkomfort with relatively little consumption of landscape. Thus, the system is to be managed on a road width of three lanes, if you dispense with a structurally -scale median strip, which is also handled in a variety of cases like this. The track separation then consists mostly of a doppelstreifigen continuous road marking or a concrete wall. After the good results on some benchmark times the system is often used for new highways when highway traffic volumes would not be appropriate, but especially in rural areas long distances to be bridged.

In the case of a missing structural separation (eg solid line instead of median barrier or green stripes), vehicles can easily fall into the oncoming traffic, especially if narrow two tracks back to a track. For such roads without physical separation, therefore, the usual rules apply also in the 2 1 system ( according to § 3 para 3 No 2 Highway Code ) to the speed limit on roads outside city limits, that is usually speed 100 part, however, are at clear distances higher speeds permitted; so, for example, on the B 31n to Stockach both in the dual than in the single-track speed of 120 fields allowed.

In hilly areas the lane change usually takes place exactly in the valley or on the top. This ensures that there is always the uphill direction, two strips available and trucks and slower vehicles may be outdated.

Examples: B 1, B 2 between White Castle and Roth, B 4 in Uelzen, B 10 between Pirmasens and Landau, B 16, B 20, B 25 between Möttingen and Harburg ( Schwaben), B 33, B 54, B 56n, B 59n between Rommerskirchen and the A 1 in Cologne -Bocklemünd, B 67 between Bocholt and Maria Veen, B 72, B 71 at Gardelegen, B 178, B 210, B 300, B 314 with Blumberg, B 482, B 54 between the motorway Haiger -Burbach (A 45) and the winner Agriculture airport.

Free two-lane road height

In the two-lane road, the height- free motorway similarity exists only in the exit notice and the height- free exits and entrances (for example: B 218, bypass Bramsche - Engter ).

Construction sites

Construction sites are on motorway-type highways usually less expensive set up as on highways. While one always tries at highway construction sites, where possible, provide at least two lanes in each direction of travel is, at roadworks on motorway-type highways often provided only one lane in each direction.

Truck toll

Since 1 January 2006, the truck toll applies to selected federal motorway-like roads, corresponding sections are signposted.

Other countries


In the Netherlands there are motorway-like roads. These roads are usually as Autoweg (plural: car because of) designated and posted as a dual carriageway (). You are officially no motorways, but some have two structurally separate carriageways or "only" motorway-like ascents and descents. The top speed is 100 km / h An example is N 281


In Italy, motorway-like roads that are not subject to toll, highway ( German: expressway, literally: Super Street ) called. Formally called such roads Strada principale extraurbana ( except local main street). On them a maximum of 110 km / h may be driven (for comparison: on the highways max 130 km / h and on non-upgraded state roads 90 km / h. ). It often is the feeder road ( raccordo autostradale ) or bypass roads or upgraded lines of state roads. The signage is blue, like on normal roads, while the highways are marked green.


In Iceland there are no highway signs, but there are some motorway-like roads. By 2008 there were a total of 16 km, all in the vicinity of Reykjavík. The end of 2008, a further 28 km long was opened motorway-like road that leads from Keflavík towards Reykjavík.

Baltic States

In Estonia and Latvia, there is no highway signs, but there's motorway-like roads near Tallinn and Riga.


In Poland, highways (Polish: Drogi ekspresowe; singular Droga ekspresowa ) highway-like, usually with two lanes and at least two lanes, expanded. However, there are also two-lane highways with one lane available in this a top speed of 110 km / h applies. On motorway-like highways a speed limit shall be 120 km / h In Polish motorways (Polish: Autostrady; singular Autostrada ), characterized by a greater width of the driving and hard shoulder and a larger turning radius in contrast to the expressways, a top speed valid from 140 km / h In contrast to the motorways the highways are toll free for passenger cars.


In Russia, the streets of the highest order Magistralen hot. This is not about highways, but often at highway Similarly developed highways with multiple lanes. In more remote areas, they may also consist of only one road with one lane around large cities also hundreds of kilometers with three or more lanes to be expanded to include two lanes.


In Slovakia highways (Slovak Rýchlostné cesty, singular rýchlostná cesta ) are highway-like, mostly expanded with directional dual carriageway with two lanes, but there are also single-lane highways exist. Legally, they are largely equated the highways ( Slow Diaľnice, singular DIAĽNICA ), but have narrower lanes and a hard shoulder and small turning radius and are posted as a dual carriageway. The speed limit on the motorways as 130 km / h, on a single-lane sections 100 km / h


In the Czech Republic the highways (Czech: Rychlostní silnice ) are mainly expanded highway-like. One difference between these roads and the Czech motorways (Czech: Dálnice ) is the narrower shoulder. Both on the highways as well as on the highways the speed limit is 130 km / h


The national roads are signposted in blue font transport GR. Until the early 1990s did not prepare a highway construction, the national roads were instead since the late 1950s performed with two tracks and two emergency lanes. When overtaking, it was common that the car on the hard shoulder dodged to allow overtaking, with increasing levels of traffic all four tracks were used regularly. Much of the four-lane national roads are now often serves as a toll- free alternative to the highway, but they are rarely continuously crossing-free and have tighter radii and tracks.

Great Britain

In addition to the highways, there is also a dense network of four-lane highways separate direction (A roads ), but in which all species are approved by vehicles and which intersect with other roads. This type of highways is also known as dual carriageway and correspond to the motorway-like roads in Germany. Motorway roads have at irregular intervals so-called "U- Turns" ( German: semi-circle turn ) or roundabouts ( traffic circles ). The top speed is like on the British motorways 70 mph (112 km / h).

The great north-south A1 road (London- Edinburgh) has several sections motorway status, bears there but no motorway (M, motorway ) name, but is - even on road signs - as A1 (M ) are shown.


In U.S., there are at least 80,000 km of car -track-like roads that have no separate highway signs. Most highways are part of the federal -funded interstate highway system, the counterpart of the national motorway network. In addition, there are federal funded U.S. highways, the black and white design of the license plate of which builds on the license plate of the Interstates and State Routes (or State Highways, depending on the state ). Within the larger cities and in their environment, but also between cities, where an interstate " missing", these two types are in part as highways with limited driveways and / or structurally separate two-lane carriageways.


In Canada, there are plenty of motorway-like roads with a total length of approximately 15,000 km. You have no separate highway signs. In the province of Quebec they are called Autoroutes ( with separate signs).


In Spain, there are plenty of motorway-like roads, called dual carriageway, with a special signage. The majority are "real" highways for which no toll is payable, as undertaken by public institutions and some were built with EU funds. On a Autopista must expect tolls against it. On all autovías the maximum applies. permissible speed limits for highways (currently 120 km / h ) unless otherwise indicated.


In Greater Lima, the Pan-American Highway and some other main roads are expanded highway-like.


There are in Sweden approximately 300 km motor roads with 2 1 system, intersection freedom and structural separation. They have similar highways a level of security.


In addition to the highways, there is also a dense highway- like expressway network in Thailand. Thailand's highways have a total length of over 60,000 kilometers. Most Thai highways are two lanes open to traffic and often have a hard shoulder, hard shoulder called. Multi-lane roads have periodically so-called "U- Turns" ( German: semi-circle turn ) and traffic light controlled intersections, which slow the flow of traffic. These lanes are comparable to those in the UK "dual carriageway ". You are in Thailand also called "Divided Highway", where the two carriageways are separated. In many local through traffic and at some intersections, there are parallel on each side of a minor road ( Frontage Road). The speed limit is city 50 km / h out of town 90 km / h
