Generally defined as a person with sufficient skill, knowledge, or experience in a given field so as to be capable of drawing inferences or reaching conclusions or opinions that an average person would not be competent to reach.

• A. Fact witness
• B. Lay witness
• C. Expert witness
• D. Character witness

Answer: (C)

An expert witness is defined by having specialized skill, knowledge, or experience that allows them to draw conclusions or opinions that an average person couldn’t reach. This enables them to interpret technical evidence, apply professional standards, and provide informed judgments about complex issues such as fire behavior, cause-and-origin analysis, or safety system performance. This role differs from a fact witness, who testifies only about what they directly observed; a lay witness, who can only convey perceptions within common knowledge; and a character witness, who speaks to a person’s character rather than technical conclusions. The description best matches an expert witness.
