In a road works zone with a contraflow arrangement, which sign would indicate this lane setup?

• A. Road Works Ahead
• B. No Entry For Vehicles Over 3.5 T
• C. One Lane Crossover At Contraflow Road Works
• D. Hazard Panel For Flammable Liquid

Answer: (C)

Recognizing the sign that shows a contraflow arrangement in a road works zone. In contraflow, traffic from both directions is moved through a single lane or a narrowed section, so signs that tell you how the crossover works are essential for safe navigation. The best sign is the one that states “One Lane Crossover At Contraflow Road Works” because it explicitly communicates that the works use a single lane for both directions and indicates how traffic should be routed through the area. This helps you slow down, follow the temporary routing, and be prepared for merging or opposing traffic in the contraflow lane. The other options don’t describe the lane arrangement: they either give a general road works warning, impose an unrelated vehicle restriction, or indicate an unrelated hazard.
