What does Rule 406 permit to prove conduct in accordance with routine practice?

• A. Habit evidence is admissible to prove conduct in accordance with habit
• B. Character evidence by reputation
• C. Evidence of a routine practice is admissible to prove misconduct
• D. Expert testimony is required to prove routine conduct

Answer: (A)

Rule 406 lets you use evidence of a person’s habit or an organization’s routine practice to prove that the person acted in conformity with that habit or routine on the occasion in question. The idea is that when a behavior is a regular, automatic response to a specific cue, it’s more reliable to infer that someone will act the same way again than to rely on general character traits. Habit evidence is specifically about those regular, particularized actions, while routine practice works in the same way for groups or organizations.

That’s why this option is the best fit: it captures the essential rule—that evidence of a habitual behavior can be admitted to prove conduct in accordance with that habit. It’s broader than mere reputation or general character, and it doesn’t require expert testimony. The other choices either misstate the scope of Rule 406 (character reputation is not the correct basis to prove routine conduct) or unfairly limit the rule (routine practice proven only as misconduct) or inaccurately demand expert testimony for routine conduct.
