What documentation must be visible to clients at all times by tour guides?

Tour guides are required to have a valid license visibly displayed to clients at all times as it serves as proof of their qualifications and adherence to local regulations governing tours. This license ensures that the guide has met specific training and regulatory requirements, providing clients with an assurance of professional standards. It demonstrates the guide's legitimacy and capability to conduct tours safely and responsibly.

While other documentation like a state ID, an employee handbook, or a company identification badge might be relevant in various contexts, they do not convey the same level of professional credibility as a valid license. A state ID could verify identity, but it does not demonstrate the necessary tourism credentials. An employee handbook is for internal use and does not pertain to client interactions. A company identification badge may identify someone as an employee, but without a valid license, it does not establish their authority or experience in conducting tours. Thus, having a valid license is crucial for ensuring compliance and building trust with clients.
