She's
not entitled to that expectation. It's
illegal for her to do so.
not if she was complying with the HC, which is what I said. Point being that if she's not then she takes liability, there's no argument about that. But if she is, ie if her interpretation of "a large enough gap" is within the bounds of reasonability, then she has a reasonable expectation that the truck driver will comply with the very first bit of 170
170
Take extra care at junctions. You should
* watch out for cyclists, motorcyclists, powered wheelchairs/mobility scooters and pedestrians as they are not always easy to see.
If a car pulls across to turn right the truck will slow, just in case the car doesn't clear the junction in time. Even now the same should be true for cyclists but too often drivers don't create the necessary space and some simply lean on their horn to clear their way. The proposal makes it that much more obvious that they should.
My recollection of my training is that "a large enough gap" means that other vehicles should not need to slow down or swerve to avoid you if you pull out from a side road into a main road. If you're expecting other traffic to do that when you're riding or driving, then you're a dangerous road user and I hope I don't encounter you on the roads.
that sounds right to me (the first bit as well as the second- I actively encourage you to not drive on roads I want to use

) certainly causing someone to swerve cannot be right, but there are times when it's perfectly reasonable to pull out even though that may, or may not, mean others have to slow. Otherwise junctions simply wouldn't work in thick traffic.
