Why this is the answer
The correct answer in the official bank: It is forbidden to overtake,inside the tunnel or to try overtaking, within a distance of 50 meters before or after the tunnell
Overtaking in and near a tunnel is dangerous. Therefore it is forbidden to overtake, or to try overtaking, inside the tunnel and also within 50 meters before and after it. Sufficient lighting does not permit overtaking. Stay behind the slow vehicle until you are out of this area.
