On the A1 near Lübeck is a sign that irritates me a little bit. Limit is there 120km/h. Then comes a sign “Tempo 80” with the addition “at wet”. About one kilometer further comes a sign “Tempo 100” without additional. In my opinion I should be allowed to drive again 100 from here also at wet. 500m further, however, comes a sign “80 at wet end”. From now on, where does speed 100 apply again? Marcel
