Road numberGermany
1. Road number
A road number is a number or combination of letters and numbers used to identify a particular road or route within a road network. Road numbers help drivers follow routes, distinguish between different types of roads and navigate between cities, regions and countries.
Road numbers are commonly displayed on route markers and direction signs. Their format, colour and prefixes vary between countries and may indicate whether a route is a motorway, national road, regional road or international route.
How are road or route numbers identified in Germany?
Common examples include A Autobahnen and B Bundesstraßen. Follow the route shield and destination signs, because some routes share a section of road or change designation at a border.

Does a route number by itself establish a speed limit in Germany?
No. A route number is an identification and navigation reference. Legal speed limits and other restrictions come from the applicable road category, vehicle rules and regulatory signs; the same route number may include sections with different limits.

What should you check when following a numbered route in Germany?
Check the route number, destination, direction and junction or exit signs. If the route shares the road with another number or continues onto a different road class, follow the signs rather than relying solely on a navigation app.
