Question 362 in the bank

Which of the following traffic signs will be placed or marked following traffic sign 144?

Five numbered items: 821 road with white triangles, 806 dashed white line, 513 yellow zigzag, 101 red triangle with two humps, 144 red triangle with one hump.
  1. 513
  2. 806
  3. 101
  4. Correct answer: 821

Why this is the answer

The correct answer in the official bank: 821

Traffic sign 144 gives advance warning of a speed bump further along the road. After it, white triangles are marked on the road, marking 821, which show where the speed bump is and remind drivers to slow down. Sign 101 looks similar, but it warns of an uneven road and does not mark the location of the speed bump.
