When is lay opinion permissible?

• A. Only for matters requiring specialized expertise
• B. Based on the witness's perception and helpful to the jury without requiring expertise
• C. It is never permissible
• D. It must be backed by a statistical analysis

Answer: (B)

Lay opinion is allowed when it’s based on the witness’s own perception and helps the jury understand the evidence or a fact in issue, and it does not require specialized expertise. This means a lay witness can offer judgments like “the driver seemed distracted,” “the car was moving fast,” or “she appeared nervous,” as long as those judgments come from what the witness actually perceived and would assist the jury without needing expert training. If a person’s testimony would require scientific, technical, or professional knowledge to be reliable, it should come from an expert rather than a lay witness. The described standard matches the idea that lay opinions are grounded in personal perception and helpful to the jury, not based on statistics or specialized analysis.
