Trucking expert witnesses address FMCSA regulatory compliance, driver qualification, hours-of-service violations, cargo securement, maintenance records, and motor carrier safety management in commercial vehicle accident litigation. CDL instructors, former FMCSA inspectors, and transportation safety engineers are the typical practitioners.
Catastrophic trucking accidents — jackknifes, override crashes, cargo spills — generate high-value claims that justify substantial expert investment. The typical trucking case requires both a trucking regulatory expert (FMCSA compliance) and an accident reconstructionist (crash physics). Budget accordingly.
Electronic logging device (ELD) data, GPS telematics, and dash cam footage have transformed trucking litigation. Experts who understand how to analyze ELD data and identify HOS violations are in high demand. Data extraction and interpretation is often billed at a premium rate.
Negligent entrustment and negligent hiring theories require the trucking expert to review driver qualification files, MVR history, and carrier safety ratings — a document-intensive process that drives up retainer requirements. Carriers with poor CSA scores are particularly vulnerable to these theories.
