After a serious commercial truck accident, the physical damage to the vehicles may reveal only part of what happened. Important evidence can also exist inside the truck’s electronic systems, including information about speed, braking, driving hours, and vehicle operation immediately before the collision.
Unlike photographs or physical debris, electronic evidence may be overwritten, deleted, or lost during routine business operations.
When a trucking company fails to preserve relevant information after a Missouri crash, determining what caused the collision can become considerably more difficult.
At Gogel Law Firm, our St. Louis truck accident attorney understands the importance of identifying and preserving evidence that may establish negligence by a commercial driver, trucking company, or another responsible party.
What Electronic Evidence May Exist After a Commercial Truck Crash?
Modern commercial trucks often have multiple systems that record vehicle and operation data.
Depending on the truck’s equipment and the company’s technology, potentially relevant evidence may include:
- Electronic Logging Device (ELD) Records: Information about driving time, duty status, and compliance with federal hours-of-service requirements.
- Engine Control Module (ECM) Data: Available records of vehicle operation, potentially including speed, engine activity, and other information.
- Event Data Recorder Information: Data captured around triggering events that may help investigators reconstruct a collision.
- GPS and Fleet Tracking Records: Vehicle location, routes, stops, and movement patterns.
- Onboard Camera Footage: Video that may show traffic conditions, driver behavior, or the moments preceding impact.
- Electronic Maintenance Records: Inspection histories, reported mechanical problems, and repairs.
Not every truck records the same information. The availability and usefulness of electronic evidence depend on the vehicle, installed systems, and crash circumstances.
How Can Important Trucking Evidence Disappear?
Some electronic systems retain information only for limited periods or overwrite older data as they record new information. Other records may be deleted according to company retention schedules.
Evidence can also be lost when a damaged truck is repaired, electronic components are replaced, or a vehicle returns to service before investigators obtain relevant data.
These circumstances make early preservation especially important after a serious collision.
A trucking company may initially retain records as part of its ordinary operations. However, once litigation is reasonably anticipated, its duty to preserve potentially relevant evidence can extend beyond routine recordkeeping.
What Happens When a Trucking Company Fails to Preserve Evidence?
The loss or destruction of relevant evidence is often called spoliation.
In Missouri litigation, spoliation consequences depend on the circumstances, including the nature of the missing evidence, the company’s preservation obligations, and whether the destruction was intentional.
Missouri courts may permit an adverse inference when a party intentionally destroys or conceals relevant evidence under circumstances supporting an inference of unfavorable content. However, missing information does not automatically prove negligence, and an accidental loss does not necessarily justify the same consequences as deliberate destruction.
A trucking company’s explanation for missing records, its knowledge of potential litigation, and the steps it took to preserve information can all become significant issues.
Why Electronic Records Matter When Drivers Disagree
Consider a collision on Interstate 70 near St. Louis involving a commercial truck and a passenger vehicle.
The truck driver claims traffic stopped unexpectedly, leaving insufficient time to avoid the crash. The injured motorist maintains that the truck was traveling too fast and following too closely.
Available electronic records may help investigators assess vehicle speed, braking activity, driving time, and other circumstances before impact.
Without those records, the investigation may depend more heavily on witness statements, physical evidence, photographs, and accident reconstruction.
Electronic evidence does not always establish exactly what happened, but it can provide an independent source of information when accounts conflict.
Why Early Investigation Is Critical in Missouri Truck Accident Claims
An attorney investigating a serious truck accident may send a preservation notice identifying potentially relevant electronic and physical evidence.
Depending on the circumstances, the notice may address vehicle data, driver logs, dispatch communications, camera footage, maintenance records, and other information associated with the collision.
Prompt action can reduce the risk that investigators cannot examine relevant records because they were overwritten or destroyed.
Preservation is only one part of the investigation. Establishing liability still requires determining whether negligent conduct caused the collision and resulting injuries.
Protecting Your Rights When Trucking Evidence Is Missing
When electronic records disappear after a serious truck accident, injured motorists may face additional challenges proving how the collision occurred.
Understanding what information existed, whether it should have been preserved, and why it is unavailable can become an important part of the case.
If you or a loved one was injured in a Missouri commercial truck crash, Gogel Law Firm can investigate the trucking company’s conduct, identify potentially relevant evidence, and pursue accountability when negligence caused your injuries.
