Which persons may you refuse to transport?

You answered correctly. According to German traffic regulations, you are allowed to refuse transporting people if they would endanger the safety and order of the operation, or if they would put the safety of other passengers at risk. This helps prevent dangerous situations and ensures the safety of everyone in the vehicle. However, simply being accompanied by a dog is not a valid reason to refuse transportation unless the animal itself poses a danger. Knowing these rules helps you make the right decisions for safe and responsible driving.
