Lay witness testimony is typically limited to which of the following?

• A. A complex medical diagnosis
• B. A witness's expert opinion on the law
• C. Simple conclusions derived from direct observation
• D. Hearsay statements

Answer: (C)

Lay witnesses testify about what they personally perceive and about simple inferences drawn from those perceptions. They’re not there to offer specialized analyses or legal conclusions; that role belongs to experts. So their testimony tends to be straightforward observations or common-sense conclusions that a layperson could derive from direct experience. That’s why describing simple observations—like what a person saw or heard in the situation—fits best. Complex medical diagnoses require medical expertise, expert opinions on the law fall to professionals in those fields, and while a lay witness may recount statements they heard, that involves hearsay rules and isn’t the normal scope of lay testimony.
