A bike lane marked by a solid white line, that motorised vehicles are
banned from entering. Unlike a one with dashed lines, where they can
if necessary to avoid another vehicle.

Um, the bus lanes that I see in London have solid white lines, so not sure
how that works :/

Quite well, because they are mandatory *bus* lanes. As well as the
signage, the width is a bit of a giveaway. You might have to travel a
bit out from central London to see a bike-only lane.
