Which sign shows the appropriate traffic lanes at a junction ahead?

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

Answer: (D)

Positioning in the correct lane before a junction is guided by signs that show which lanes lead to which exit or movement. The sign that shows the appropriate traffic lanes at junction ahead directly provides this guidance, mapping each lane to its intended destination. This lets you settle into the right lane well before you reach the junction, reducing last‑minute lane changes and increasing safety.

The other options relate to motorway features rather than lane usage at a junction: one marks the end of a motorway, another shows countdown markers to an exit, and another marks the start of a motorway. They don’t tell you which lane to be in for the upcoming junction, so they don’t fit the question.
