The signs and rules with no equivalent back home.
Droga z pierwszeństwem
Yellow diamond, white border. You are on the priority road. Traffic joining from side roads must give way to you. Keep going.
Koniec drogi z pierwszeństwem
Same diamond with a black slash. From here on, give way to the right. This is the one people miss — you keep driving as if you still have priority.
Ustąp pierwszeństwa
Upside-down triangle. Same as a US yield sign, but taken seriously — you are expected to stop if anything is coming.
Skrzyżowanie równorzędne
Nobody has priority by sign, so priority to the right applies. Often there is no sign at all — the rule still applies.
Tabliczka T-6a
A small white plate under the diamond showing the junction. The THICK line is the priority road. If it bends and you are going straight, you are leaving the priority road and must give way — including to a car turning across you.
You are driving up from the bottom. The priority road comes up with you and then turns off to the left. Carry straight on and you have left the priority road — so the car following it has right of way, even though from your seat he is cutting across you.
