Calculating the time it takes to travel a distance on the Autobahn can be more difficult than you think, especially if you have a tight schedule.
Free speed of course, but if you have a car with a top speed of 250 km / h, it’s rare to successfully go 250 km per hour anyway. The speed can be quite jerky as speed limits and free speed vary over every kilometer. Keeping a speed of 200 km / h means that you will get very tired in the long run and develop a kind tunnel vision. You get exhausted and must be extremely attentive.
Also, the weather determines. Many stretches have dynamic speed limits, so, for example, rain decreases the allowed speed.
Autobahn stau differs from state to state
Finally, Stau is what really destroys a travel planning. Stau, which means traffic jam, is very common on the Autobahn and sometimes lasts for several hours. The risk for Stau is biggest in the states of western Germany, while the eastern states such as Saxony and Mecklenburg-Western Pomerania have hardly any problems at all. Stau is reported via digital signs by the way or via radio or web.
How many kilometers on Autobahn?
What is a suitable distance to handle on a day in Germany? Around 500-600 kilometers are common. Then you have time to get stuck in Stau, but still be at the hotel for the evening. When I have driven stretches of 1000 kilometers or more on the Autobahn, I have regretted me afterward. So, a journey between Sweden and northern Italy should be planned for more than two days’ journey for all’s well-being.
