Which sign tells you the lanes to use at a junction ahead?

• A. Appropriate traffic lanes at junction ahead
• B. Start of motorway
• C. End of motorway
• D. Countdown markers

Answer: (A)

Signage that shows which lanes to use at an upcoming junction is specifically there to guide you into the correct lane in advance, so you reach the right exit or continue straight without last‑minute lane changes. This sign will illustrate the lanes and the corresponding directions, helping you position early, reduce speed appropriately, and indicate when a lane change is needed.

The other signs mentioned don’t serve this purpose. A sign marking the start of a motorway simply tells you you’re entering a motorway, not how to position yourself in lanes for a junction. A sign for the end of a motorway signals you’re leaving the motorway, again not about lane choices at a junction. Countdown markers provide distance information or timing cues, but they don’t tell you which lanes to use for a junction ahead.

So the sign that communicates the appropriate traffic lanes at the junction ahead is the one you’d rely on to choose the right lane.
