Yellow box junction rules first started in London in 1967. They help to ensure that junctions on busy roads are kept clear. The basic rule is that you shouldn’t stop in one. You shouldn’t enter the box unless you’re sure you can reach the other side without stopping in the middle. You will normally see them at crossroads controlled by traffic lights. Although any busy area which needs to be kept clear may have a box junction.
There is an exception to this however; when waiting for oncoming traffic before completing a right turn, you CAN wait within the box providing that stationary traffic is not blocking your exit.
How many cars do the yellow box junction rules allow area?
There is no limit to the number of drivers who can wait in the box. But you do need to take into account how much space is available beyond the yellow road markings. If queuing traffic means for instance that there’s only enough space for a couple of cars at the exit, then you should hold back if there are two or more drivers ahead of you.
The trick is to keep your distance from drivers ahead when you’re approaching any kind of junction. Open up some space so that you have a better view of the room available. That way, you will have time to decide on whether you can forward into position, or whether you should hold back and wait outside the box.
Yellow box junction rules mean that you may earn yourself a fine if you block one, and some of them even have cameras triggered by sensors. Fall foul of one of these and you may find yourself getting a demand for payment dropping through your letterbox!
