Instruction :
Is there really no speed limit on the German Autobahn?

Response:
While it is true that there are sections on the German Autobahn without any speed restrictions, most portions of the Autobahn have speed limits.  Speed limits often range from 80 km/hour to 120 km/hour.  When driving on the Autobahn be aware that speed limits can change with little notice.  You will find your fellow Autobahn users speeding up or slowing down rapidly depending on changes in the posted speed limit.  If this is your first time traveling on the Autobahn you should exercise caution as you might not have experienced driving in conditions with rapidly changing speed limits or with no speed limit at all.
