The German autobahn

The German autobahn

More German than Lederhosen and German beer, the autobahn has achieved an almost legendary status worldwide as the motorway with no speed limit, but the reality on the roads is a little different. In this guide, we separate the facts from the myths, and offer some handy tips for driving on the autobahn in Germany. 

What is the autobahn?

Officially known as the Bundesautobahn (federal motorway), the autobahn is Germany’s controlled-access highway system. 

How long is the autobahn?

The German autobahn is one of the longest motorway networks in the world (third only to the United States and China), stretching a total length of some 12.996 kilometres. 

A brief history of the autobahn

The idea of a “car-only” road, along which vehicles could travel unhampered by pedestrians, bicycles and animal-powered transportation, was first conceived in Germany in the mid-1920s. However, amid the mass unemployment and hyperinflation in the crisis-stricken Weimar Germany, the idea remained just an idea until 1929, when the first car-only road opened between Düsseldorf and Opladen.

The first crossroad-free road

It was the mayor of Cologne, Konrad Adenauer (who would later become Germany’s first postwar chancellor) who finally managed to finance and construct the first crossroad-free motorway in 1932.

Still in use today as the A 555, this road was a short 20-kilometre stretch between Cologne and Bonn with two lanes in each direction, and a maximum speed limit of 120 kilometres an hour (although most cars at the time could manage little more than 60). 

The Reichsautobahn

Shortly after the Nazis came to power in 1933, this road was downgraded to the status of a “country road”. After years of rejecting car-only roads as benefiting only aristocrats and capitalists, Adolf Hitler came to recognise their potential - their power to simultaneously seduce the public and oil Nazi military might - and decided that he would be the one to build the first autobahn: the Reichsautobahn.

The first section opens

With the opening of the first section between Frankfurt am Main and Darmstadt in 1935, the German autobahns became the first limited-access, high-speed road network in the world. With 130.000 labourers participating in the construction, the goal was to complete 1.000 kilometres of road per year.

But, as the war raged on, more and more workers were swallowed up by the arms industry and few could be spared, with the exception of POWs and Jewish forced labourers. By 1941, just 3.800 kilometres of road had been completed, and by 1942, construction had virtually ground to a halt.

Ruin & Reconstruction

After the war, thousands of kilometres of autobahn remained unfinished, and those that had been completed were in pretty rough shape. In West Germany, the government quickly embarked on a widespread, laborious reconstruction programme, investing in new sections of autobahn and making improvements to older ones. Finishing the incomplete sections took so long that some stretches did not open to traffic until the 1980s. 

Some autobahns were even cut off by the Iron Curtain, meaning they couldn’t be completed until after the Reunification of Germany in 1990. The East German government had rather neglected their autobahns, choosing to use them for heavy military traffic rather than investing in their reconstruction. After German Reunification, the East German autobahns were incorporated into the West German autobahn network, to make a total length of 8.800 kilometres. 

What you need to know before driving on the autobahn in Germany

If you're about the get behind the wheel, avoid traffic mishaps and directional confusions with these tips for driving on the autobahn in Germany. 

Driving on the autobahn: Traffic laws & Regulations

Keep your journey as smooth as the autobahn’s famously well-maintained surfaces, by observing these rules.

General rules

Keep these legal requirements in mind:

  • No passing on the right (except in slow-moving traffic)
  • Always double-check your side-view mirror before moving into the left-hand lane
  • Slower traffic stays to the right
  • Always use your indicators, even for passing
  • Stick to the speed limit (more details below)
  • Tailgating is illegal and punishable with a fine

Legal requirements

If pulled over on the autobahn, you must be able to produce: 

Safety items

You must also have the following items in your car:

  • A reflective vest
  • A warning triangle
  • A first aid kit

Autobahn speed limit

Germany is the only country in Europe to not have a general speed limit. Instead, it has a “recommended speed limit” of 130 kilometres per hour. You can choose to drive faster than this - it’s not illegal, but it’s not recommended. At the other end of the scale, you shouldn’t really be driving any slower than 80 kilometres per hour (even if you're just learning to drive!) 

However - contrary to popular belief in the speed-limit-free-autobahn - there are sections that do have speed restrictions. These might be around construction sites, at junctions, on dangerous sections of roads, or in and around cities. When driving through these sections, you are expected to follow the posted limits, and not resume normal speed until you see an end-of-limit sign or a new speed limit. 

A 2017 report by the Federal Road Research Institute found that 70,4 percent of the German autobahn network had only an advisory speed limit, 6,2 percent had temporary speed limits due to the weather or traffic conditions, and 23,4 percent had permanent speed limits. In the face of concerns about safety and the environment, however, the proportion of the autobahn covered by speed restrictions is steadily growing. 

Traffic jams & The “Rettungsgasse

Whenever traffic backs up on the autobahn due to an accident or any other emergency, German traffic law requires all drivers to form an emergency vehicle lane (Rettungsgasse) to give easy access to ambulances, fire engines or police

If the road you are on has two lanes in each direction, drivers must move their vehicles as far as possible over to the left and right, creating a middle lane that can be used by the emergency services. If there are more than two lanes, drivers in the right lanes move to the far right, while drivers in the third or fourth left lane move to the far left. Keep your doors closed and do not stand in the emergency lane, to avoid impeding emergency vehicles. 

Parking, rest & truck stops

You should take a break at least every two hours. The autobahn has plenty of rest stops (Raststätten) with petrol stations, restaurants, shops, eating areas and toilets. German service stations have a reputation for being expensive and fairly low-quality, but the situation is gradually improving. 

Note, however, that you will normally have to pay to use the toilet - and it’s common autobahn practise to bring your own loo roll with you!

Toll roads

Unlike plenty of its European neighbours, Germany allows passenger cars to drive on its autobahn network for free (for the time being). Drivers of vehicles weighing 7,5 tons and above must pay a toll via an automatic system known as Toll Collect. A toll for passenger cars looks set to be introduced in the near future, but disputes over EU law have caused long delays. 

If you cross the border into either Austria, Switzerland or France, however, you will be expected to pay a charge for using their high-speed motorways. While in France you pay per kilometre at a turnpike toll, in Switzerland and Austria you need a flat-rate toll sticker (Vignette) to display in your car’s windscreen. 

Finding your way

If you’re used to driving on highways - like those in America - that mention compass directions, it can be confusing trying to navigate your way from A to B on the German autobahn. The blue directional signs don’t tell you which direction you are travelling in - instead, you need to know the names of the major cities along your route (or use a GPS system!) 

Good to know: The autobahn numbering system (see below) is another way of telling if the road you are on runs East to West or North to South. 

How fast can you drive on the autobahn?

If the section of autobahn you are on has a speed limit - temporary or not - you must stick to it. In sections without a limit, driving faster than the advisory speed limit of 130 kilometres per hour is not illegal. 

However, you should note that driving this fast can result in you having increased liability - from the point of view of your car insurance company - in the case of a collision. Some insurers will not pay out for any damages.  

How safe is the autobahn?

With cars zipping back and forth between lanes and overtaking each other at speeds of 200 kilometres an hour plus, the autobahn can seem intimidating to the uninitiated. But the lack of speed limit is actually justified on the grounds that it makes driving safer. As recently as 2019, Federal Transport Minister Andreas Scheuer boasted that Germany’s motorways were the “safest in the world.” 

In general, motorways are certainly safer than other types of roads - with the risk of fatality on highways approximately six times lower than on urban and rural roads - but the OECD also holds that the risk of fatality increases significantly with speed. 

Thanks to better engineering and road construction, the fatality rate on German roads has declined consistently since the 1970s; nonetheless, it is still well above the European average. As of 2019, the fatality rate over each 1.000-kilometre stretch of German autobahn is 30,2 percent, compared with the EU average of 26,4 percent. 

You might argue, therefore, that the German autobahn is not even the safest motorway in Europe, let alone the whole world.

Do other countries have an autobahn?

Everywhere else in the world, the word “autobahn” is used to refer specifically to the German highway network. In German, however, it is a generic term used to describe the motorway system in any given country. 

In theory, then, plenty of other countries have an autobahn. It just might be nothing like the German autobahn! In Germany, the word “Bundesautobahn” is preferred to make specific reference to the German autobahn network. 

Autobahn facts & Figures

Here are some useful and fun facts about the autobahn in Germany:

  • The autobahn’s total length is 12.996 kilometres, enough to drive from Berlin to Darwin in Australia!
  • The longest possible fast stretch of autobahn is between Hamburg and Berlin down the A 24 - 150 kilometres of road with no speed limit in sight.
  • Maintaining the autobahn costs Germany 825.000 euros per mile each year.
  • The biggest autobahn pileup in history occurred near Hamelerwald in 2009, and involved a whopping 259 cars!
  • The autobahn’s numbering system is very logical: East-West routes are even-numbered, while North-South routes are odd numbered (see below). 

Autobahn map

The current autobahn numbering system was introduced in 1975. All autobahn routes are prefixed with a capital “A”, which stands for “Autobahn”, followed by a blank space and a number. 

The main autobahns crossing Germany have a single-digit number, while shorter autobahns of regional importance (e.g. those connecting major cities) have a double-digit number and lesser roads have a three-digit number.  

While North-South autobahns are usually numbered from West to East (easterly roads have higher numbers), East-West routes are numbered from North (lower numbers) to South (higher numbers). 

The system is as follows:

  • A 10 to A 19 cover parts of eastern Germany, including Berlin, Saxony-Anhalt, parts of Saxony and Brandenburg
  • A 20 to A 29 cover northern and northeastern Germany, including Hamburg
  • A 30 to A 39 cover northwestern Germany, including Lower Saxony and Thuringia
  • A 40 to A 49 cover the Rhine-Ruhr region, including Frankfurt and the Rhine-Main region
  • A 52 to A 59 cover the Lower Rhine region, including Cologne
  • A 60 to A 67 cover Rhineland-Palatinate, Saarland, Hesse and northern Baden-Württemberg
  • A 70 to A 73 cover Thuringia, northern Bavaria and parts of Saxony
  • A 81 covers Baden-Württemberg
  • A 90 to A 99 cover southern Bavaria
