You want to overtake. Why should you not do so?

You got the correct answers. When considering overtaking on rural roads in Germany, it is essential to ensure that there is no oncoming traffic and that your view of the road ahead is clear and unobstructed. If there is oncoming traffic, overtaking is too dangerous and not allowed, since you might not have enough space and time to complete the maneuver safely—this is why answer 1 is correct.

Likewise, bends in the road reduce your visibility, making it impossible to judge whether the opposite lane is free for the entire time needed to overtake. Even if the road marking allows overtaking, you must not do so if you cannot clearly see far enough ahead. That's why answer 2 is also correct.

The condition of the road surface (answer 3) could be a factor in some cases if there is, for example, ice, heavy rain, or loose gravel making overtaking specifically dangerous. However, in standard situations like in this scenario, only oncoming traffic and bends are the deciding factors against overtaking.

Whenever you are unsure if you can overtake safely and fully, you must wait until the road ahead is clear and straight, with no oncoming traffic and full sight of the situation. This ensures you stay within German traffic regulations and maintain safety for all road users.
