Especially if you are used to the traffic of another country, it is hard to drive through a crossing without to protect yourself with breaking and looking. But this is necessary when you have priority. The risk of collision because of a break at a green light is much higher than a collision with someone who drive over red light.
Exceptions are crossings with priority to right. But there you should just do a short look to left. If you see a car, which is not doing an evidently mistake, you should not stop.
The sign “Give way” doesn´t force you to stop like the “stop sign” if no car with right of way is close. But sure the priority rules for pedestrians and bicycles are still valid.
