Which sign indicates that only one lane is available to crossover at contraflow road works?

• A. Road Works Ahead
• B. No Waiting During Times Shown
• C. One Lane Crossover at Contraflow Road Works
• D. Hazard panel indicating flammable liquid

Answer: (C)

In contraflow road works, traffic from both directions is funneled through a single, temporary lane so the works can be carried out while vehicles still move past. The sign that reads “One Lane Crossover at Contraflow Road Works” directly communicates this setup: only one lane is available for crossing to the opposite carriageway, so drivers must share that lane and follow the directions of any controllers or signs. The other signs don’t specify lane capacity or crossover rules: “Road Works Ahead” just warns that works are ahead, “No Waiting During Times Shown” imposes a waiting restriction, and the hazard panel for flammable liquid indicates a hazard, not how many lanes are open.
