Against whom should insurance for vehicles be filed to ensure compliance?

The correct choice is the Airport ID Badge Office, as this office is typically responsible for enforcing security regulations and ensuring that all personnel at an airport have the required credentials to operate within the airport environment. Filing insurance information with this office ensures that the vehicle you are operating meets the necessary safety and liability standards for compliance with airport regulations.

In addition, the Airport ID Badge Office may require proof of insurance as part of the process for obtaining a badge or permit that allows access to restricted areas of the airport. This requirement helps maintain safety and accountability among all individuals and entities operating on airport grounds.

While the Department of Transportation and the FAA have regulations that might pertain to commercial transport and safety overall, they do not handle individual compliance matters related to vehicle insurance specific to airport operations. Similarly, your direct employer may have their own internal policies regarding vehicle operation, but compliance with airport regulations specifically necessitates interaction with the Airport ID Badge Office.
