Junction with vehicles R, L, D and B

The diagram contains four vehicles, R, L, D and B. The mapped official questions do not establish a complete sequence that omits L; they establish precise relationships. R may enter without giving way to any vehicle, D may proceed after R, and B must wait for all the others, including R, D and L. Therefore D does not pass first, B cannot move together with R or before D, and R does not wait for B and D. Apply the priority rules to the actual paths and account for every visible vehicle even when an individual statement names only some of them.
