On every german Autobahn which is also a paneuropean road you show in OM3 the euro road sign, but thats not used in germany on road signs in reallity.
We are using here the national road numbers, the european number is in very selden cases shown as side mark on a road sign.
For example: OM3 shows E37 (Euro road 37, green label) but when you look to the road signs you will find only the A1 (Autobahn 1, blue label)
