Legal situation with traffic lights at on-path cycle lanes.

But the cycle lane ends before the lights - by the time you actually reach the lights, you should be on the road, no?

EDIT: What I said above was incorrect. As pointed out by other users, the blue circle sign means that when the cycle lane ends, the path becomes shared use, and it is perfectly legal to continue to cycle on the path (while giving way to pedestrians)

But cyclists arent allowed on the footpath. Do you either move onto the road, or dismount and walk to the next section of cycle lane?

This is an interesting question. Personally I don't stop as the bike lane is off road, I don't see why the lights would apply to a path. In my experience there's usually no way for bike traffic coming from the right side to join the path, at least not around the immediate area of the junction so no real risk of collision plus you'd see them joining up ahead to merge in.

It’s a shared space sign, so legally cyclists are allowed use the path even though there’s no marked cycle lane

Good point, missed that. Shared use path, so just continue on, giving way to pedestrians. I don't believe the traffic lights have any effect in that scenario

That's the standard design being used around Limerick in the suburbs even on brand new roads.

The inverted triangle is generally a Yield sign. Confusing if it also has another meaning i.e. "shared space". Also the lights may well apply to pedestrians if they incorporate a pedestrian crossing, It is not clear to me if they do in this case.

Overall some rather bad and unclear design. Nothing surprising there.

It looks like the cycle lane ends. It then becomes a footpath for pedestrians. Obviously you can't cycle on the path so you should move out onto the bus lane, I would have thought.

Did you miss the blue round sign indicating a shared space?

That's the spirit caller.

Not to mention that, even when it is a legally shared footpath, many pedestrians do not seemed to be aware of the signage and just assume you are cycling illegally on the footpath anyway.
