Habit Evidence (FRE 406)
What is the Habit Evidence (FRE 406)?
Evidence of a person's habit or an organization's routine practice is admissible to prove that on a particular occasion the person or organization acted in accordance with the habit or routine practice, regardless of corroboration.

Definition
Federal Rule of Evidence 406 permits the admission of habit and routine practice evidence to prove conduct on a specific occasion — a sharp contrast to the general ban on character evidence under FRE 404. The rule reflects the common-sense observation that habitual behavior is a reliable predictor of conduct because it involves a semi-automatic, reflexive response to a particular type of situation.
The critical distinction between habit (admissible under FRE 406) and character (generally inadmissible under FRE 404) lies in specificity and regularity. Habit refers to a person's regular practice of responding to a particular kind of situation with a specific type of conduct. It is semi-automatic, invariable behavior — like always locking the door upon leaving, always using a turn signal, or always reading a patient's chart before prescribing medication. Character, by contrast, describes a general disposition or propensity, such as being careful or reckless.
FRE 406 is notably generous in its terms. The evidence may be admitted regardless of whether it is corroborated and regardless of whether there is an eyewitness to the specific occasion in question. Habit evidence may be proved by testimony about specific instances of the conduct or by opinion testimony describing the habitual practice. For organizations, routine practice evidence operates similarly — proof that a company always follows a particular procedure can establish that it followed the procedure on the occasion in question. Courts look for adequacy of sampling (sufficient instances) and uniformity of response (near-invariable behavior) when determining whether conduct qualifies as a habit.
Key Elements
- 1The evidence describes a regular practice of meeting a particular kind of situation with a specific, uniform response
- 2The behavior must be semi-automatic or reflexive, not a general character trait
- 3The habit or routine practice must be adequately established through sufficient instances
- 4The conduct must be nearly invariable — not merely frequent
- 5The evidence is offered to prove conduct on a particular occasion consistent with the habit
- 6No corroboration or eyewitness testimony is required
Landmark Cases
Halloran v. Virginia Chemicals Inc.
41 N.Y.2d 386 (1977)
Distinguished habit from character by requiring proof of a deliberate and repetitive practice, allowing evidence of plaintiff's routine method of heating refrigerant.
Meyer v. United States
464 F. Supp. 317 (D. Colo. 1979)
Addressed organizational routine practice, holding that evidence of a company's standard mailing procedures was admissible to prove a particular letter was mailed.
Loughan v. Firestone Tire & Rubber Co.
749 F.2d 1519 (11th Cir. 1985)
Clarified that habit requires more than a tendency — it must be a regular, semi-automatic response demonstrated through adequate instances.
Exam Tips
- The key exam distinction is habit vs. character: habit is specific, regular, and semi-automatic; character is general and volitional. Always classify the evidence on the spectrum.
- Look for triggering situations — habit evidence involves a specific stimulus producing a nearly invariable response (e.g., 'Every time she leaves the house, she locks the door').
- Remember that habit evidence does not require corroboration — this is a common exam question designed to test whether students know the rule's generous terms.
Common Mistakes to Avoid
- Confusing habit with character — saying someone is a 'careful driver' is character; saying someone 'always stops at the intersection of 5th and Main' is habit.
- Believing that habit evidence requires corroboration or an eyewitness — FRE 406 explicitly states neither is required.
- Failing to establish sufficient regularity — occasional or even frequent conduct is not enough; the behavior must be nearly invariable.
Memory Aid
Habit is SPecific and Semi-automatic; Character is General and voluntary. Think: 'Habits happen without thinking.'
