A Title 10 infantry company at an inauguration can be ordered to establish traffic checkpoints. True or False?

• A. True
• B. Depends on security level
• C. Only with congressional waiver
• D. False

Answer: (D)

The key idea is that federal troops are restricted from performing civilian law enforcement tasks on U.S. soil. Establishing traffic checkpoints is a police function, and without a specific legal authorization, Title 10 forces cannot be used for that role. At an inauguration, there isn’t an insurrection or equivalent authority in place to justify using an infantry company for traffic enforcement, so a Title 10 unit cannot be ordered to set up traffic checkpoints. Therefore, the statement is false. In practice, security support would come through non-enforcement roles or through other authorized authorities (such as Insurrection Act triggers or other clear statutory approvals), not by directing a Title 10 infantry company to run traffic stops. The other options don’t fit because the limitation isn’t overridden by security level, and a simple congressional waiver isn’t the standard mechanism for enabling this kind of police function.
