When should you start indicating left when waiting in traffic at a red traffic light? - Whilst waiting in traffic? - 25m before the junction? - Just before you reach the junction?

For those saying he indicated early enough. The vehicle is fitted with an audio device that says “vehicle turning left” when the indicator is turned on. The audio recording only just played that phrase as it started turning. Thus they didn’t indicate early enough.

This instruction video from a HGV driving instructor shows how to indicate for a left turn, he indicates for 10 seconds on approach to the junction.

That is perfect timing, if he indicates earlier it might appear he’s pulling into the bus lane, he is still 30 or 40 metres from the turn. He definitely shouldn’t have been indicating left when sat next to the bus. It really shouldn’t matter no one should be on his inside.

Indicating they are pulling into a bus lane is not a problem. The hazard that needs to be avoided is turning across a cyclist at a junction or pulling across them. Correct you shouldn't indicate too early if crossing multiple junctions, as someone might pull out in front of you

Why where you even trying to squeeze thru the narrower road inside an HGVs blind spot ?

Things that didn't happen for £500 please. I was cycling past stationary traffic in a bus / cycle lane. The lights ahead turned green. I positioned my self to rejoin traffic behind the HGV and in front of the vehicle behind.

In Denmark no vehicles will turn unless the cycle lane is free. All vehicles will wait for the bikes to pass. Denmark is a great place to ride bikes, even in heavy traffic

Technically those are the rules in the UK. But I wouldn’t trust anyone to do that.

according to drivers: the entire time, including the turn, and if you wobble then you're a bad cyclist and road tax etc etc etc

It seems the order has changed from when I took my lessons. It's now manoeuvre, signal, mirror (the last two being optional!)
