Which of the following is an indicator that someone might identify as a Sovereign Citizen?

Claiming to be a Sovereign Citizen is a clear indicator of someone who identifies with that movement. Sovereign Citizens often assert that they are not subject to government authority and may reject the legitimacy of laws and regulations. This self-identification can manifest in various ways, including the use of specific language or legal arguments that align with the ideology of the movement.

In contrast, frequent travels for work, participation in community events, and maintaining a regular job are common behaviors that can be exhibited by individuals from various backgrounds and do not serve as indicators of Sovereign Citizen beliefs. These actions do not specifically relate to the ideology that dismisses government authority and legal structures. Thus, the most definitive indicator within the options provided is the active claim of being a Sovereign Citizen.
