When approaching an intersection where a green light is illuminated together with a supplementary green arrow pointing right (dopunska zelena strelica), what does this indicate?

1. You may turn right in the direction of the arrow, but you must yield to pedestrians crossing and vehicles moving on the intersecting road
2. You have absolute priority over all other vehicles and pedestrians while turning right
3. Right turns are mandatory and you may not proceed straight even if the main light is green
4. You must come to a complete stop for 3 seconds before turning right
