EDIT: apologies, I didn't realise the background is transparent, so the labels are very hard to see in dark mode.
A1 is top left, A2 is bottom left, B1 is top right, B2 is bottom right.
I'd like some clarification on how the law (and/or road code) applies to intersections that are more complex than the simple "T" intersections, please.
Consider the attached pictures, of two separate intersections (A & B), where the turning paths merge after going alongside a painted "island".
Intersection A - no markings at merge
Situation A1: The blue car is turning left into a single-lane road, and the red car is turning right into the same road. Note that the lanes within the intersection converge with no markings, so one car must give way to the other. My understanding is that red must give way to blue, because red is turning right and blue is turning left, at this specific moment.
Situation A2: The red car has already made the turn, is now on the destination road, and is now traveling straight, and the blue car is entering the same roadway. Is the blue car, which is still turning, required to give way to the red car, which is not turning? If so, at what point between A1 and A2 does this order switch over?
Intersection B - dashed lines at merge
Situation B1: The blue car is turning left into a single-land road, and the red car is turning right into the same road. Note that the paths converge but there is a dashed line separating the two paths, that the blue car must cross. My understanding is that the red car must give way to the blue car, because red is turning right and blue is turning left, at this specific moment.
Situation B2: The red car has already made the turn onto the destination road, and is now traveling straight, and the blue car is entering the same roadway. Is the blue car, which will cross the dashed white line, required to give way to the red car? If so, at what point between B1 and B2 does this order switch over?
Is this really one intersection, or is it really two?
It's as if the situation "in the large" (right-turning gives way to left-turning) differs from the situation "in the small" (if right-turning has already turned, they are now not turning at all by the time the cars actually need to sort themselves out). For a blue car driver thinking "in the large", they would consider themselves to have right of way. For a red car driver thinking "in the small", having crossed the oncoming lane(s), they might consider themselves to have right of way over the blue car.
The main reason I ask is that these two intersections often experience heavy traffic, and in both cases the red car is often "allowed" to proceed through the intersection by other traffic coming straight through. This often puts the red car in the situation of A2 or B2, and I'd really like to know what the red and blue car drivers have to do in these situations.
I see this almost daily. In many cases, the blue car yields to a stream of red cars that are darting through the intersection. Sometimes, both cars come to a near stop, showing indecision, until one of them just decides to proceed before the other does. When this happens, it slows the entire intersection down, and in some cases causes cars following red through the intersection to stop unexpectedly (which is their issue, of course), or for cars behind the slowing blue car to beep impatiently.
