Question 690 in the bank

What is the meaning of the following traffic sign?

Two tall white posts, each with a black band with slanted ends; the left shows two white circles, the right a vertical white rectangle. Meaning: Direction and warning posts at the side of the road.
  1. Level crossing 300 meters ahead.
  2. Correct answer: Direction and warning posts at the side of the road.
  3. Guardrail marking.
  4. Railway barrier ahead at a work-site

Why this is the answer

The correct answer in the official bank: Direction and warning posts at the side of the road.

These white posts with a black band and reflectors stand along the edges of the road. They mark where the road ends and show its course, especially at night, in fog or in rain, helping drivers keep a correct position in the lane. They have nothing to do with a level crossing or a barrier, and they are not a guardrail marking.
