Guiderà in Repubblica Ceca, domanda sull’apprendimento della strada prioritaria.

If I am red and need to go straight and leave the priority road, do I need to yield to someone coming from blue since they are on the priority road?

I think the more unclear situation is for the blue car, if he goes straight (thus leaves the main road) and the red would be coming in the opposite direction from the side road, i.e. from his right. If I remember correctly, the blue car should give way to the car from the right then, but in reality the cars from the right will just stop there and give way to the blue car. It’s confusing and drivers must communicate in such scenarios.

My driving teacher using this comparison (roughly translated), when you’re on a priority road at an intersection, just imagine an unmarked intersection with no cars on the non priority roads and follow the right hand rule. In this case, if it was an unmarked intersection, they’re on your right hand side so they get to go first

Thick line has priority.
