This sign means?

1. River ahead
2. Bump or uneven pavement
3. There may be water flowing over the road ✓
4. Pavement is slippery when wet

Answer: C. There may be water flowing over the road

The sign means that there may be water flowing over the road.

Why this is the answer

The handbook's list of common warning signs includes a sign whose meaning is that water may be flowing over the road. Warning signs tell you about dangerous conditions, so this sign points to water crossing the pavement rather than a river, a bump, or a generally slick surface. The passage gives this meaning directly, so the answer follows from the handbook.

Why the other answers are wrong

• A. River ahead — The passages do not list a river-ahead meaning among the warning signs, so this choice does not match the sign described.
• B. Bump or uneven pavement — Bump or uneven pavement is not mentioned as the meaning of this warning sign in the passages.
• D. Pavement is slippery when wet — The rain passage explains that wet roads can be slippery, but it does not say this sign means the pavement is slippery when wet.

Remember it

Remember it as water moving across the roadway, not a river beside it or a slick wet surface.
