Hazard signs of Hong Kong. Hazards or warnings are symbolised in Hong Kong by the signature red outline over a white background. Text or symbols are rarely used in signage, rather using symbols and images to depict and communicate the warning at hand.
The first picture warns patrons about crossing the road while there is traffic. The second is a road works hazard sign. The bottom sign indicates a red light camera on the road ahead, and the final picture indicates a no standing zone in public areas.
