The question asked must not seek such a broad range of information that the witness is allowed to narrate the entire story with one or two answers.
Proper examinations proceed in a question and answer fashion.
Generally, the Court may allow some leeway in ruling on this objection. At times the witness s answer may go beyond the scope of the question, even though the question itself called for a specific answer. However, questions about a person s ability to tell the truth are always admissible. If the opinion asked for would be known to a person of common knowledge and the witness had an opportunity to observe the matter for which the opinion is requested, the witness may answer the opinion question. This is called a lay opinion, as distinguished from an expert opinion.
