Then we have this odd type of road used to save money: One lane in each direction plus a center lane that alternates between the directions. For maybe a kilometre, the northbound traffic has two lanes and then the southbound traffic has two lanes for a kilometre instead
We have that on hills and mountains. Going up there are two lanes, but where visibility is good enough, the lane going down has an interrupted double line towards the center lane, which menas you can use the center lane for overtaking from both lanes. For that reason everybody calls the center lane overtaking lane. Works quite well where it is used but led to frequent frontal crashes when they tried to introduce it everywhere. Now you have some roads with two incredibly wide lanes...
In Austria we always used to have yellow lines everywhere, with the exception of hard shoulder lines and zebra crossings that where always white. The border lines where yellow though, so when the hard shoulder ended at an exit ramp you suddnely had the line change from white to yellow and back again. In 1994 a worldwide treaty came into force and they changed everything but no parking lines to white. Actually they even changed those and then changed them back to yellow again...
We also have blue lines in the limited time parking zones.
Speed limit is 50/100/130, and now they're discussing a 160 speed limit. the best argument against: We're in Austria. With a 130 limit people go 160. With a 160 limit they'd go 220. So we best leave the speed limit as is.
The Germans don't have a general expressway speed limit at all.
