Question 172 in the bank

The following illustration shows a wide road. Which number in it marks a road?

A photograph from above of a multi-lane road with two cars. White double-headed arrows, numbered 1 to 8, stretch across different widths.
  1. Correct answer: 2
  2. 8
  3. 1
  4. 3

Why this is the answer

The correct answer in the official bank: 2

A road is the whole area open to traffic, from edge to edge, and it includes the carriageways, the lanes and the shoulders. The arrow marked 2 stretches across this entire area. The other arrows cover only parts of it, such as one carriageway, a lane or a shoulder.

Topic: Rules and regulations. The bank marks it for these classes: Light truck (C1), Heavy truck (C), Bus (D), Motorcycle (A), Tractor (1), Private car (B).
