What is one responsibility of the DOT?

One significant responsibility of the Department of Transportation (DOT) is ensuring compliance with international aviation practices. This role is crucial as it involves overseeing the implementation and adherence to regulations and standards set forth by international aviation agreements and organizations. By doing so, the DOT helps to maintain safety, security, and efficiency in air travel, not only within the United States but also in collaboration with international partners.

In this capacity, the DOT monitors and evaluates the practices of airlines and airports, ensuring that they align with established protocols and contribute to the safe operation of air transportation on a global scale. This oversight helps to foster trust and coordination in the international aviation community, ultimately benefiting travelers and the industry as a whole.

The other options are less aligned with the primary functions of the DOT. For instance, while airline ticket pricing may be influenced by regulations, it is not directly overseen by the DOT. Similarly, managing passenger boarding processes and controlling airport security staff typically fall under the purview of individual airlines and airport authorities rather than the DOT.
