You should not overtake another vehicle when there are **cyclists traveling in the opposite direction** because this can put them in danger. Overtaking under these conditions involves invading the opposite lane, which reduces the available space for cyclists and increases the risk of collision. Additionally, it is important to maintain a **minimum distance of one and a half meters** when overtaking cyclists to ensure their safety, which would not be possible if there are cyclists in the opposite lane. Therefore, it is better to wait until there are no cyclists in the opposite direction before performing the overtaking maneuver.
