Do the traffic signs in Czech and Austria drive the same as us ?

Drive according to the traffic lights, and it should be fine in general. At intersections without traffic lights, note that the yellow triangle has the right of way and can proceed first. The red inverted triangle does not have the right of way and must yield. When entering a roundabout, you do not have the right of way, but when exiting a roundabout, you do. Except for overtaking, don't drive on the leftmost lane. That's about it.
