You’re allowed to turn right at a box junction, but you must do it in a very specific way to stay legal and safe.

Key rule in one line

If there’s oncoming traffic, you may wait in the box junction only if your exit road is clear; otherwise, wait before the box.

What you should do step by step

  1. Check your exit first
    • Look at the road you’re turning into.
    • If there isn’t enough space for your car to fully clear the box, stay back and do not enter the yellow criss‑cross area.
  1. If your exit is clear but oncoming traffic is blocking you
    • Drive slowly into the middle of the box, positioning your car ready to turn right, but still in your lane.
    • Stop there and wait for a safe gap in oncoming traffic.
    • When there’s a safe gap, complete your right turn and clear the box.
  1. If there’s a traffic light at the junction
    • Move into the box and wait to turn right (again, only if your exit is clear).
    • If the light turns red while you’re waiting in the box to turn right, you may still finish the turn as soon as it’s safe, so you’re not left stranded in the junction.
  1. What you must NOT do
    • Don’t enter the box if your exit is blocked by stationary traffic.
    • Don’t stop in the box “just in case” it moves; you must be sure you can clear it, unless you’re turning right and only held up by oncoming traffic or right‑turning vehicles.

In theory‑test style wording, if you want to turn right at a box junction and there’s oncoming traffic, the correct choice is: wait in the box junction if your exit road is clear.

Mini “Quick Scoop” recap

  • Box junction = yellow criss‑cross area meant to keep the junction clear.
  • General rule: don’t enter unless you can clear it.
  • Special right‑turn rule: you can stop in the box while waiting for oncoming traffic to clear, but only if your exit is clear.
