Truck Accident Expert Witness

What a semi truck expert witness examines after a crash

A truck accident case is rarely decided by the moment of impact alone. It is decided by what the driver's duty status actually was, what the carrier knew about that driver, and whether the vehicle was maintained and inspected as the Federal Motor Carrier Safety Regulations require. Bill reviews electronic logging device records against fuel receipts, toll transactions, dispatch communications, and shipper check-in times to reconstruct the hours preceding the collision. Where the records conflict, the conflict itself is often the finding.

The same review extends to the driver qualification file, the carrier's safety management controls, prior roadside inspection history, and maintenance records under Part 396. Each element is mapped to the operative regulation so the opinion states a standard rather than an impression.

Evidence that disappears first

ELD records carry a six-month federal retention floor. Dashcam footage and engine control module data are commonly overwritten in days or weeks. Counsel who send a preservation letter naming the correct systems in the first weeks of a truck accident matter usually end up with a stronger record than counsel who request documents generically. Bill's post-crash evidence preservation checklist sets out what to demand and when. For counsel new to expert work in this space, how a trucking expert witness works in a case explains the engagement from preservation through testimony.

Where truck accident cases most often turn

Most commercial vehicle crash matters resolve around a small set of recurring regulatory failures. Fatigue and Hours of Service issues are addressed in fatigue and HOS cases. Falsified or edited records are addressed in logbook falsification cases. Hiring, training, and supervision failures are addressed in carrier liability cases, and file defects in driver qualification cases.

Retaining Bill on a truck accident matter

Engagements begin with a case review and consultation, which gives you a direct read on whether the regulatory theory holds. From there Bill produces written expert reports and provides deposition and trial testimony. He reviews every matter personally and responds Monday through Friday, typically within one business day.
