Start with the signals and the actual situation when deciding who goes first. Priority from the right is a general rule with exceptions, not an automatic answer. These Spanish Category B examples are original learning material, not official questions.
The same junction, without signs
Both roads are paved. There is no officer, traffic light, rail vehicle or special manoeuvre. A yields to B, approaching from A’s right. Article 57 includes exceptions: paved roads over unpaved approaches, rail vehicles, traffic already in a roundabout, and motorway traffic over joining vehicles.
Change only B’s sign
Now B yields to A on the priority road. B cannot use the right-hand rule to ignore the sign. A STOP at that approach would also require a complete stop before proceeding when permitted.
Yielding means not forcing another driver to change speed or direction abruptly. It does not mean racing across before they arrive.
Entering a roundabout
Unless signals provide otherwise, circulating traffic has priority over entering traffic. B waits for A here. This drawing concerns entry only, not lane choice for an exit.
Once inside, do not cross an occupied lane to exit from an inner lane. Signal and change lanes when safe, respecting traffic in the lane you are joining. Having entry priority does not grant priority for every later manoeuvre.
Three quick checks
Can A go first in the first drawing because its street is wider? No. Width does not replace the rule applying in this example.
Does B still have priority in the second drawing because it is on the right? No. It must obey give way.
Can priority let you enter a blocked junction? Not if you would stop inside and obstruct it. Article 59 requires avoiding that blockage.
Practise the detail that changes the decision
Before choosing, explain which signal controls your approach and who would have to brake if you moved. Then repeat the example with just one signal changed.
Review road signs, speed in context and three reasoning scenarios. Open the priority lessons.
