Question 565 in the bank

Is a “restricted vehicle” permitted to use a road in which the following traffic sign is placed?

A round blue sign with a thin white border showing the white number 55.
  1. Yes, driving at a minimum speed of 55 k.p.h.
  2. Yes, driving at a maximum speed of 55 k.p.h.
  3. Yes, on a freeway only.
  4. Correct answer: No.

Why this is the answer

The correct answer in the official bank: No.

The sign marks a road for vehicles that are able and permitted to drive at a speed of at least 55 k.p.h. A restricted vehicle cannot, or is not permitted to, reach that speed, so it may not use the road. The number on the round blue sign shows a minimum speed, not a maximum speed.
