Under FRE 701, lay opinions are admissible if:

• A. They are about the ultimate issues in the case.
• B. They are based on the witness's perception and help explain testimony in a non-technical way.
• C. They are based on scientific data and require expert testimony.
• D. They are legal conclusions.

Answer: (B)

Under Rule 701, lay opinion testimony is allowed when it rests on the witness’s own perception and helps explain the testimony in a way that is non-technical. This means a witness can share simple, common-sense judgments drawn from what they personally saw, heard, or observed—things like noting someone appeared intoxicated, or that a vehicle was moving quickly—without needing specialized knowledge. Such opinions help the fact-finder understand the facts without involving expert analysis or legal conclusions. That's why the correct choice describes opinions that are based on perception and presented in a non-technical way.
