Are speed limits in Poland, both the motorways and in built up areas and, also in Germany on the Autobahn, sign posted well? Or not?
Yes, Poland is fantastic at signing speed limits. No hassle here - after every junction, the speed limit (if different from the normal limit for that type of road) will be signed. When you enter/leave a town, it's also very clearly marked. The speed limit signs are the least of your problems ;)
in Germany there is no speed limit on the Autobahns unless there are those overhead sings lighted showing you the speed limit - in good conditions these are visible from about a mile
Not always, I can think of the A12 from Swiecko to the Berliner Ring - there's only about 4-5 signs the whole way, warning you that it's 120km/h for the entire motorway. Ridiculous.
On entering Poland make sure you have a pack of XL pampers ready. Not for faint-hearted motorists I,m afraid. Good luck.
Ah, it's not that bad. Either that, or I'm just used to it.
