When dealing with the public, a technician should NOT?

Threatening anyone while dealing with the public is highly inappropriate and unprofessional. It undermines the trust and respect needed to effectively communicate and resolve issues. In any public-facing role, especially as a traffic signal technician, maintaining a safe and respectful environment is paramount. Threats not only escalate situations but can also lead to serious consequences for both the technician and the organization they represent.

In contrast, the other options focus on positive and constructive interactions, such as using clear communication, maintaining professionalism, and listening to the public's concerns. These behaviors promote a better understanding and foster a collaborative atmosphere, essential for effective problem-solving in community settings.
