- End of urban road.
- End of non-urban road section.
- End of road-section in which trucks are allowed to drive on the road’s “hard shoulder”.

The correct answer refers to signs 422 and 423 because: 422 prohibits overtaking for heavy vehicles only, and 423 cancels this prohibition. These differ from 420/421, which apply to all vehicles.
422/423 = no-overtaking for heavy vehicles only
