TMR put this up on their Facebook asking who has to give way, but that’s too easy. A much more complicated question is: what does the law say around indicating?
I’ve seen people say only blue must indicate, others say both must indicate, and yet others say neither must indicate. Which is correct?
Good point, and you’re right. That statement I made was not well thought through.
I agree that two lanes become one centre lane (and it’s possible that I interpreted the last photo example wrong with the photo quality).
What would you think if a car on the centre lane put their left indicator on? Personally, I would assume they want to enter that side road or a driveway. That’s my reasoning for why I don’t believe an indication would be appropriate.
I think neither is obliged to indicate here, they’re both continuing fully in the direction of their lanes. The lane changes, and just as you don’t indicate in the T intersection example when the lane curves left, you wouldn’t need to indicate as the lanes blend (rather than one merging into the other, which to be honest, doesn’t benefit from an indication either).
