Question 358 in the bank

Which of the following traffic signs informs about a change in the number of lanes?

Signs 622: blue square, bent line joining upward arrow; 145: red triangle, up and down arrows; 109: red triangle, inward-curving lines; 308: blue square, red and white arrows.
  1. 109
  2. 145
  3. Correct answer: 622
  4. All four signs.

Why this is the answer

The correct answer in the official bank: 622

Sign 622 is a blue square information sign that shows the lanes of the road, with one line joining the main arrow to indicate that a lane ends and the number of lanes changes. Sign 145 warns of two-way traffic, and sign 109 warns that the road narrows. So not all four signs announce a lane change. When you see it, prepare early to merge into the continuing lane.
