What does the "dip" sign warn you about on the road?

  1. School crossing

  2. Downgrade

The correct answer is: Downgrade

It is important to slow down when approaching a dip to ensure safety while driving through the area. The other options are incorrect because: A. The "School crossing" sign warns about the presence of a school zone and the possible presence of children crossing the road. C. The "No passing zone" sign indicates areas where passing another vehicle is not allowed, typically due to limited visibility or potential hazards. D. The "Farm machinery" sign is used to warn drivers about the possible presence of slow-moving farm equipment on the road.
