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?
Yup, that part is easy enough. The part in doubt is who has to indicate in this scenario. I contend section 45(2) and (3) both apply, so both drivers must indicate (blue indicate right, orange indicate left). Others have made cases for only blue, or for neither.
What would the bike even indicate?
Left, because they are merging with the line of traffic to their left.
I think you're imagining these sort of "two merge into one but you have to guess which" lanes. I'm not sure but i think you might.
The image clearly shows the blue lane merging into the orange, not them "merging equally."
But on that note we do have a sign showing that people need to join "like a zipper" as it were, taking turns.
So it'd depend on which lane last had a person merge.
But this is in Finland. Dk bout straya
