Box Junction Penalty
"Roland Perry" wrote in message
... In article m, Martin Underwood writes It seems to me that this advice is rather naive, because it assumes that the only impediment to the "car in front of you that's also waiting to turn right" is the flow of oncoming traffic - which will eventually stop. What if the real reason that the car in front can't turn right is a traffic queue on the road to the right. In that event, both of you will be "marooned" in the middle of the box junction when the lights change :-( Isn't the situation that you describe covered by the "are only stopped from doing so by oncoming traffic, or by other vehicles waiting to turn right" clause - the implication being that you must not enter the box if anything *else* prevents you completing the turn - for example the fact that traffic on your right is backed-up as far as the box. I think you need a crystal ball. Imagine you are the first of the right- turning cars. The road to the right is clear (at least one space to turn into). But the oncoming traffic prevents you turning. And then an oncoming car turns left, and fills up that space you used to have. Are you suddenly a criminal? The same for the next car back, observing (if indeed the sight-line is unobstructed) that there are spaces for two cars in the road to the right, initially. You've misunderstood what I said. As I see it, there are two situtations: 1. If you're turning right and traffic on the road that you want to take is backed-up as far as the box junction, you do not enter the box junction, even though you are wanting to turn right - because you are not *only* prevented from turning by the oncoming traffic but *also* because your exit from the box junction isn't clear. 2. If the exit on the right is clear but the only reason you can't turn right is because of oncoming traffic, you may enter but must remain in the middle of the road and not go as far as the exit from the box because this would block oncoming traffic. It is usually only practicable for one vehicle to sit in the centre of the road - any cars behind the "lead car" will form a barrier which will block oncoming traffic that wants to turn to its right. In case 1, when your exit becomes clear you enter the box junction and wait in the centre - unless there's no oncoming traffic in which case you complete the turn. In case 2, when there's no more oncoming traffic you complete the turn. In either case, an oncoming, left-turning car may "steal" your space between the time that you start to move and the time when you would complete the turn and leave the box junction. In this case you will be stranded on the box junction, probably just before its exit, blocking oncoming traffic. In all cases, I'm using "oncoming" to mean traffic that's going in the opposite direction to your original direction before turning right. |
