Which sign warns of the risk of grounding?

• A. A triangular warning sign showing a boat near shore
• B. A sign indicating traffic turning right
• C. A sign indicating a pedestrian crossing
• D. A sign indicating no entry

Answer: (A)

In road sign language, a triangular sign with a red border is a warning sign, and the symbol inside tells you the specific hazard ahead. A sign that shows a boat near the shore communicates a water-related hazard: the risk of grounding, where a vessel could run onto the seabed in shallow water or changing tides. That’s why this sign is the one that warns about grounding.

The other signs point to different, non-water hazards or rules—turning right, a pedestrian crossing, or no entry—so they don’t signal the risk of grounding. When you see the boat-near-shore sign, slow down and be alert for shallow water or submerged hazards if you’re near a coast or tidal area.
