On the narrow one-way street in Beuningen a parking bay becomes free, exactly big enough to back into. May you carry out that manoeuvre?
Yes, backing into a parking bay is allowed, even on a one-way street
No, on a one-way street any backward movement is forbidden
Explanation
Wrong — trap: exception omitted. The prohibition applies to reversing along the road and U-turns; backing into a parking bay is explicitly allowed (Book p.61-62).
