What are the regulations governing speed when overtaking?

Your answer is correct because all three points are important rules when overtaking in Germany. First, the overtaking vehicle must drive noticeably faster than the vehicle being overtaken to complete the maneuver safely and efficiently. Second, in doing so, the overtaking driver must not exceed the legal speed limit—speed limits always apply regardless of overtaking. Third, the person being overtaken must not speed up during the overtaking process, as this could create dangerous situations and make overtaking more difficult. Together, these rules ensure that overtaking is done smoothly and safely for all road users.
