Frequently Asked Questions
What is a forensic transportation engineer?
A forensic transportation engineer applies transportation and traffic engineering principles — roadway design, traffic control, human factors, and vehicle dynamics — to investigate crashes and other transportation-related incidents for litigation, providing technical analysis and expert witness testimony.
What does a traffic engineering expert witness do?
A traffic engineering expert witness evaluates roadway design, signal timing, sight distance, work zone conditions, and traffic control devices to determine whether they met applicable standards and contributed to a crash, then presents those findings in reports and testimony.
How do I find an engineering expert witness for a lawsuit?
Look for a firm with ACTAR-accredited reconstructionists, licensed professional engineers (PEs), and a track record of expert witness testimony for both plaintiffs and defendants across the specific specialty your case requires — crash reconstruction, human factors, commercial vehicle compliance, roadway design, and others.
What types of cases use human factors expert witnesses?
Human factors expert witnesses are commonly retained in cases involving driver distraction, perception-response time, sign and signal visibility, and product design — anywhere a person’s perception or reaction to their environment is at issue.
