You are allowed to wait on the yellow grid (box junction) markings only when you want to turn right and are stopped from doing so by oncoming traffic, or by other vehicles waiting to turn right. In this case, you may enter and wait in the box junction even if your exit road is not clear. You must not enter the box junction if your exit is not clear and you are not turning right, as this can cause traffic obstruction and may lead to a fine. This rule ensures that box junctions are kept clear to maintain traffic flow, except for the specific case of waiting to turn right when blocked by oncoming traffic or waiting vehicles.
