In which department do I need to apply for a business car to call a travel agency?

This situation needs to be applied in the transportation department.

Commercial vehicles are affiliated with travel agencies to handle road passenger transport business licenses according to law. Travel agencies do not have their own commercial vehicle licenses, and they can only operate legally by relying on the affiliated fleet. Affiliated travel agencies still need to operate in accordance with relevant laws and regulations and bear corresponding responsibilities. Violation of relevant laws and regulations will be punished accordingly.
