The Evidence That Trucking Companies Want to Disappear
Commercial trucks generate enormous amounts of data. Every mile driven, every hour logged, every inspection performed, and every maintenance task completed creates a record. These records are governed by federal regulations administered by the Federal Motor Carrier Safety Administration (FMCSA). And when a truck is involved in a serious accident, these records often contain the smoking gun evidence that proves the trucking company cut corners on safety.
The types of evidence that trucking companies routinely try to destroy or fail to preserve include electronic logging device (ELD) data, dashcam and onboard camera footage, driver qualification files, vehicle inspection and maintenance records, dispatch communications, GPS and telematics data, drug and alcohol testing records, and event data recorder (black box) information.
Each of these categories tells a story. And that story often reveals hours-of-service violations, unqualified drivers, deferred maintenance, unrealistic delivery schedules, and a corporate culture that prioritizes profit over public safety.
Federal Regulations Require Record Retention
FMCSA regulations establish minimum retention periods for various categories of records.
Driver qualification files must be maintained for the duration of the driver's employment and for three years after the driver leaves the company (49 C.F.R. Section 391.51).
Hours-of-service records (including ELD data) must be retained for six months (49 C.F.R. Section 395.8(k)).
Vehicle inspection, repair, and maintenance records must be retained for one year and for six months after the vehicle leaves the carrier's control (49 C.F.R. Section 396.3(b)).
Drug and alcohol testing records have varying retention periods depending on the type of record, ranging from one year to five years (49 C.F.R. Section 382.401).
These retention periods establish a floor, not a ceiling. Once litigation is reasonably anticipated, the trucking company has a duty to preserve all relevant evidence regardless of the standard retention period. This duty supersedes any routine destruction policy.
How Trucking Companies Destroy Evidence
Automated Data Overwriting
Many ELDs and onboard computer systems are configured to automatically overwrite data after a set period, often as short as 30 days. If a preservation request is not sent to the trucking company immediately after a crash, the ELD data from the days and weeks leading up to the accident may be permanently lost. This data is critical because it shows the driver's hours on the road, rest periods, and whether the driver was in compliance with federal hours-of-service limits.
Repairing or Scrapping the Truck
After a crash, trucking companies have a financial incentive to get the truck back on the road as quickly as possible or, if the damage is too extensive, to scrap it. Repairing the truck destroys physical evidence of pre-crash mechanical defects. Scrapping it eliminates the opportunity to inspect the tires, brakes, steering components, and other systems that may have contributed to the crash.
The event data recorder (EDR), sometimes called the truck's black box, is installed in the vehicle itself. If the truck is repaired or scrapped before the EDR data is downloaded, that data is lost forever. The EDR records critical information including speed at the time of impact, brake application, engine RPM, seatbelt usage, and whether the driver took any evasive action.
Claiming the Records Never Existed
Some trucking companies, particularly smaller operations with less rigorous compliance programs, simply claim that they never created certain records. They may assert that they did not have a dashcam system, that the driver was using paper logs instead of an ELD (even though ELD mandates have been in effect since 2019 for most carriers), or that vehicle inspection records were lost.
Coaching the Driver
After a serious accident, some trucking companies instruct the driver on what to say (and what not to say) to investigators. They may direct the driver to delete text messages, avoid social media, or refrain from cooperating with the plaintiff's attorney. While the driver has a right to legal counsel, directing the driver to destroy evidence is spoliation and can result in severe sanctions.
The Consequences of Evidence Destruction
When a trucking company destroys evidence, Texas courts have several tools available to protect the injured plaintiff.
Spoliation instructions. As established in *Brookshire Brothers, Ltd. v. Aldridge*, 438 S.W.3d 9 (Tex. 2014), the court can instruct the jury that the destroyed evidence is presumed to have been unfavorable to the trucking company. This is an enormously powerful remedy because it allows the jury to infer the worst.
Sanctions. The court can impose monetary sanctions, preclude the trucking company from presenting certain evidence or defenses, or in extreme cases, enter a default judgment against the company.
Separate tort claim. In some jurisdictions, the intentional destruction of evidence can give rise to a separate cause of action for spoliation. While Texas has not yet recognized an independent tort for spoliation, the evidence destruction can support claims for fraud or obstruction.
Punitive damages. Evidence destruction can support a claim for exemplary damages under Texas Civil Practice and Remedies Code Section 41.003. When a trucking company deliberately destroys evidence to avoid accountability, it demonstrates the kind of malice or conscious indifference that justifies punitive damages.
What Your Attorney Should Do Immediately After a Truck Accident
Time is the enemy in truck accident cases. Your attorney should take the following steps within hours of the crash.
Send a spoliation letter. A written demand to the trucking company, the driver, and any third-party data storage providers requiring immediate preservation of all evidence. The letter should specifically identify ELD data, dashcam footage, driver qualification files, maintenance records, dispatch logs, GPS data, and the event data recorder.
File a temporary restraining order. If there is any indication that the trucking company may destroy evidence, your attorney can seek emergency court relief under Texas Rule of Civil Procedure 680 to prevent the destruction.
Hire an accident reconstruction expert. An expert should inspect the scene and the vehicles as soon as possible, before conditions change and before the trucking company repairs or scraps the truck.
Obtain the police report and FMCSA inspection records. These documents can identify the trucking company, the driver, the carrier's safety rating, and any citations issued at the scene.
