Colin McKenzie gurgled happily, sounding much like
they were saying:

If the wagon overtook the cyclist immediately before turning left, then
the indicators are irrelevant - the HGV driver is absolutely bang-to-
rights guilty.

What about the intermediate situation where the driver started to
overtake some distance back, didn't make it past or pull in, and then
started to indicate. Happened to me with a bus today. I shouted, and he
turned behind me.

I'd have said that was fairly clearly covered in that first scenario.

Same applies if they were both stationary at lights. If the wagon
pulled up next to a cyclist already there, then the driver is utterly
to blame. If the cyclist went up the inside of a stationary wagon, then
the cyclist is utterly to blame.

Unless there are two full lanes, and the lorry is in the offside one and
not indicating.

In L2, and turning left? I'd imagine the cars in L1 would have something
to say about that, too... Unless, of course, L1 was left-turn-only...?

Indicators are definitely relevant in this case.

I'd have said the left-turn-only signage on L1 was probably more
relevant, but that's probably just me...
