The road sign shows Falling or Fallen Rocks. Which hazard does this warn about?

• A. Slippery Road
• B. Falling or Fallen Rocks
• C. Two-Way Traffic Ahead
• D. Traffic Signals Ahead

Answer: (B)

This sign is warning you about a rockfall hazard. It shows rocks tumbling down from a cliff or hillside, so drivers need to be prepared for rocks on the road or debris that could suddenly block your path. The best approach is to slow down, scan the road and verge ahead, and be ready to stop or steer around any rocks you might encounter. Avoid stopping directly under slopes or cliffs where rocks could fall, and follow any directions from road crews if debris is present.

Other common warning signs indicate different dangers: slippery road signs show a car with skid marks, two-way traffic ahead signs have arrows in opposite directions, and signals ahead signs depict a traffic light. Those do not describe rockfall, which is why this sign points to falling or fallen rocks.
