    When following directly behind a large vehicle ahead that has already entered the box to go straight through
  4. D
    Under no circumstances, as stopping within any part of a yellow criss-cross marking is strictly prohibited at all times

Answer

You are permitted to enter and wait inside a yellow box junction when you want to turn right and your exit is clear, but oncoming traffic or other right-turning vehicles prevent you from completing the turn.
According to UK Highway Code Rule 174, drivers must not enter a box junction unless their exit road is clear. However, you are legally permitted to enter the box and wait if you wish to turn right and are only prevented from doing so by oncoming traffic or other vehicles waiting to make a right turn.

Step-by-Step Solution

1
Identify the core restriction of yellow box junction road markings.
Drivers must not enter the marked box area unless their exit road or lane is clear.
This prevents vehicles from obstructing cross-traffic and creating gridlock at busy junctions.
2
Apply the statutory exception defined in Highway Code Rule 174.
A driver turning right may enter the box to wait if their exit is clear and they are only held up by oncoming vehicles or others waiting to turn right.
This allows right-turning traffic to position itself efficiently without impeding other junction movements once oncoming traffic clears.
