Question 652 in the bank

What does it mean when a yellow arrow pointing straight ahead is marked on the road?

A grey surface with a yellow arrow pointing up. On either side of it, white arrows curve to the left and to the right. Meaning: Only public vehicles are permitted to continue driving straight ahead at the coming intersection.
  1. All vehicles are permitted to drive straight, but right-of-way should be given to buses.
  2. Every vehicle carrying at least six passengers is permitted to continue straight forward.
  3. Correct answer: Only public vehicles are permitted to continue driving straight ahead at the coming intersection.
  4. Private vehicles are permitted to carefully drive straight.

Why this is the answer

The correct answer in the official bank: Only public vehicles are permitted to continue driving straight ahead at the coming intersection.

A yellow arrow marked on the road is meant for public vehicles. When the yellow arrow points straight ahead, only a public vehicle may continue straight at the coming intersection. All other vehicles turn in one of the directions shown by the white arrows. The number of passengers in the vehicle makes no difference, and driving carefully or giving right-of-way to buses does not allow a private vehicle to drive straight.
