Question 562 in the bank

What is the meaning of the following traffic sign?

A round blue sign with a thin white border showing a white car seen from the front. Meaning: Road for motor vehicles only.
  1. Road for non-motor vehicles only.
  2. Correct answer: Road for motor vehicles only.
  3. Road for commercial vehicles only.
  4. Road for public vehicles only.

Why this is the answer

The correct answer in the official bank: Road for motor vehicles only.

The sign marks a road for motor vehicles only. The car symbol stands for motor vehicles in general, not only commercial vehicles or public vehicles. So non-motor vehicles, such as bicycles, may not use this road.
