What Goes Into a Truck Accident Investigation

October 30, 2025

Truck cases are won or lost on the evidence you preserve in the first few weeks.

The Preservation Letter

The day we take a truck case, we send a preservation letter to the trucking company demanding they hold onto driver logs, ECM data, dispatch records, maintenance records, and everything else that could be relevant. Without this letter, records can legally be destroyed on a schedule.

The Black Box (ECM)

Commercial trucks have electronic control modules that capture speed, braking, throttle position, and other critical data. We download this data with the help of experts.

Driver Logs and Hours of Service

Federal regulations limit how long a driver can be behind the wheel. Fatigue is often a factor, and the paper trail proves it.

The Investigation Team

Depending on the case, we work with accident reconstructionists, trucking industry experts, biomechanical engineers, and life care planners to build the full picture.

Why Speed Matters

The trucking company's insurance team is already on scene within hours of a serious crash. You can't afford to wait.
