Iowa sits at the crossroads of major freight corridors, including Interstates 80 and 35, where thousands of commercial trucks travel daily. When a fully loaded big rig collides with a passenger vehicle, the consequences are often catastrophic — and the evidence that proves what happened can disappear within days.
Electronic Logs and Hours-of-Service Records
Federal rules limit how long truckers can drive before resting. Electronic logging devices record driving hours, and these records can reveal a fatigued or over-scheduled driver. But carriers are only required to retain some records for limited periods, so prompt preservation is essential.
The Truck's Black Box
Modern trucks record speed, braking, throttle, and other data in event-data recorders. This information can show how fast the truck was going and whether the driver braked — but it can be overwritten or lost if the truck is repaired or returned to service.
Maintenance and Hiring Records
A trucking company can be liable for negligent maintenance, hiring, or supervision. Maintenance logs, inspection reports, and the driver's qualification file can reveal systemic problems. An attorney can demand these through a litigation-hold letter before they vanish.
Why Speed Matters
Because critical truck evidence is time-sensitive, the days immediately after a crash are decisive. Acting quickly to preserve logs, data, and records is often what determines whether a truck case succeeds.
