4 way junction, one is private car park

Faith

I've a quick question about right of way here. There's a 4 way junction near me. Three of the roads are main roads, one is the entrance/exit of a supermarket with a private car park.

This is roughly the layout, with the bottom road, as it were, being the one into the supermarket. The junction is controlled by traffic lights, with the supermarket and the road directly across from it getting green lights at the same time. My question is, if you were coming out of the supermarket and turning left, and a car is coming from the main road and turning right, who has right of way? I assumed it was the car turning left, but my mum claims that it's the person coming from the main road no matter what, and the person coming from a private car park must yield any other traffic. Can anyone clarify?

Interesting question.

My immediate reaction is that the person crossing the white line on the road should yield. But on the other hand, I can see the point about the person already being on the road also having precedence.

I think because of the traffic lights controlling the traffic exiting the car park it is treated as any other 4 way junction with the traffic having to cross the white line having to yield. However I am not sure how it would be treated if the junction did not have any lights.

Your mother is wrong. As the junction is controlled by lights, cars turning left have right of way over oncoming traffic turning right. The fact that you're coming out of a supermarket has no bearing on the situation.

....although at many junctions in the Dublin area, traffic turning left must yield to oncoming traffic turning in the same direction.

Would they be controlled by traffic lights? If both junctions have a solid green light then traffic turning left would have right of way. If however the traffic on the main rd has a green light and the traffic coming from the supermarket has a flashing amber arrow, then that's a different story.

I can't think of any junction controlled by solid green lights where traffic turning right has precedence, but I could be wrong.

Yes, now that I think of it, the junctions controlled by lights have flashing amber 'turn left' lights.

The junctions not controlled by lights have a dedicated physically seperated left turn lane with a YIELD sign on it.

Apologies for confusing the matter.
