§ 90.701, Fla. Stat. — Opinion Testimony of Lay Witnesses
Plain English
Regular witnesses are supposed to give the jury facts, not opinions — but Section 90.701 leaves room for the everyday impressions people can’t help forming. A lay witness may offer an opinion or inference about what they perceived when (1) it’s the only practical way to convey what they observed without misleading anyone, and (2) it doesn’t require special knowledge, skill, experience, or training. Think “the car was going really fast,” “he seemed angry,” or “she sounded scared” — common-sense shorthand, not expert analysis. The dividing line is simple: the moment the opinion needs specialized expertise, you’ve crossed into expert territory under § 90.702.
From the Courtroom
The lay-opinion line gets tested most with “he seemed impaired.” A bystander can absolutely say someone slurred, stumbled, and smelled of alcohol — even that they “seemed drunk.” But ask that same witness for a blood-alcohol estimate and you’ve left 90.701 for the expert world of 90.702. Knowing exactly where that line sits keeps good testimony in and junk out.
Key Points & Authority
- § 90.701, Fla. Stat. — A non-expert may give opinion/inference testimony only when it can’t be readily conveyed otherwise and requires no special knowledge, skill, experience, or training.
- Boundary with § 90.702: once an opinion depends on specialized expertise, it must satisfy the expert (Daubert) standard.
- Federal parallel: Fed. R. Evid. 701 states the same limits on lay opinion.
Federal Parallel
The federal counterpart is Fed. R. Evid. 701 — lay opinion is allowed only if rationally based on perception, helpful, and not based on specialized knowledge (which belongs to FRE 702).

Rule Text (verbatim from the Florida Supreme Court)
If a witness is not testifying as an expert, the witness’s testimony about what he or she perceived may be in the form of inference and opinion when:
(1) The witness cannot readily, and with equal accuracy and adequacy, communicate what he or she has perceived to the trier of fact without testifying in terms of inferences or opinions and the witness’s use of inferences or opinions will not mislead the trier of fact to the prejudice of the objecting party; and
(2) The opinions and inferences do not require a special knowledge, skill, experience, or training.
