You are driving on a road with one lane for each direction. A convoy of motor vehicles is driving up ahead of you. Why should you refrain from overtaking in order to prevent a dangerous situation from occurring?

Your selections are correct. Overtaking a convoy of vehicles is especially risky for several reasons according to German road rules. First, the overtaking distance required is much longer compared to passing a single vehicle, increasing the time you spend in the oncoming lane. Second, if you feel pressured to return to your lane too soon, you might cut into the convoy, disrupting their formation and causing confusion or even an accident. Third, it's often difficult to see the traffic or road conditions ahead of the entire convoy, so you may not be able to react to hazards in time. All three reasons combine to make overtaking a convoy particularly dangerous and should be avoided unless you are absolutely sure it can be done safely. This ensures your safety, the safety of the convoy, and of oncoming traffic.
