Which persons may you refuse to transport?

In this case, the selected options are correct because they address specific scenarios that pose risks to the safety and order of transport. According to German traffic regulations, transport operators have the right to refuse service to individuals who may compromise the safety of the vehicle, the passengers, or the driver's ability to operate the vehicle safely.

1. Persons who would endanger the safety and order of operation refer to individuals whose behavior could disrupt the driver's focus or the vehicle's operational integrity.

2. Persons who would endanger the safety of other passengers indicates situations where a passenger might cause harm or create an unsafe environment for others in the vehicle.

The inclusion of both options emphasizes the dual responsibility of ensuring the safety of all individuals within the transport out of respect for the law and others' rights to safe travel. Each of these factors is critical in maintaining a safe transportation environment on the roads according to German traffic laws.
