Question 418 in the bank

What is the meaning of the following traffic sign?

A red-bordered white circle with the black number 4.6, a small black triangle above and another below, pointing toward each other. Meaning: Vehicle height restriction. No entry for a vehicle that exceeds, with its cargo, the height that is indicated in the sign.
  1. Tunnel entrance.
  2. Barrier ahead.
  3. Correct answer: Vehicle height restriction. No entry for a vehicle that exceeds, with its cargo, the height that is indicated in the sign.
  4. Narrow and low roadway.

Why this is the answer

The correct answer in the official bank: Vehicle height restriction. No entry for a vehicle that exceeds, with its cargo, the height that is indicated in the sign.

A round sign with a red border is a prohibition sign, and the number between the two black triangles shows the maximum permitted height in metres. The height counts the vehicle together with its cargo, so a load that sticks up higher also breaks the rule. The sign does not mean a tunnel or barrier as such; it warns of a height limit that may come before a bridge, tunnel or any overhead obstacle.
