When a semi destroys a family's car on I-80, the investigation everyone expects starts at the crash scene — skid marks, black box data, the driver's logs for that day. Those matter, and the trucking company's own rapid-response team is gathering them before the wreckage is cleared.
But some of the most important evidence in a truck case has nothing to do with the crash. It was created months or years earlier, in an office, when somebody at the motor carrier decided this driver was qualified to operate an 80,000-pound vehicle on a public highway. Federal law requires that decision to be documented. The document is the driver qualification file, and it is the first thing I ask for.
What the carrier is required to have
FMCSA's own guidance spells out what belongs in the qualification file a motor carrier must keep on every driver it puts behind the wheel:
- An employment application (49 CFR 391.21). A driver may not operate a commercial motor vehicle without one. Non-CDL drivers list their employers for the past three years; CDL drivers, for the past ten.
- An investigation of previous employers (391.23). The carrier must investigate and document the driver's safety performance history for the three years immediately prior, including accidents and alcohol and controlled-substance violations, and document its good-faith efforts to make contact.
- The driver's state motor vehicle record, placed in the file within 30 days of the inquiry.
- An annual review of the driving record (391.25), with an updated MVR each year and documentation of who reviewed it and when.
- A road test certificate (391.31), or an equivalent — a valid CDL, or a road test certificate issued within the prior three years.
- A medical examiner's certificate (391.41). The driver must pass a medical examination and hold a current certificate, generally renewed every two years.
The file is kept for the period of employment plus three years after the driver leaves.
Why that paperwork decides cases
Read that list again with a crash in mind. Every item is a checkpoint where a company had a chance to learn something about a driver and either took it or didn't.
The three-year safety history inquiry exists so a carrier cannot hire a driver with a trail of preventable crashes and then claim it had no idea. The annual review exists so a company cannot keep a driver on the road for four years without looking at his record again. The medical certificate exists because vision, cardiac conditions and sleep disorders affect whether a person should be driving at all. When a checkpoint was skipped, the crash stops being a story about a bad moment on the highway and becomes a story about a company decision.
That distinction drives how a case is valued. A claim against a driver for negligent driving is one thing. A claim against the motor carrier for putting that driver on the road — its own hiring, qualification, supervision and retention decisions — is a different and usually much larger thing, because it reaches the company's conduct rather than one man's mistake. It is also the claim a carrier's insurer least wants a jury to hear. The same logic extends to the hours-of-service and qualification records the carrier must maintain, where the question shifts from "should he have been hired" to "should he have been driving that day."
Why the letter has to go out immediately
None of this is available at the scene. A qualification file sits in a carrier's office, and beyond its retention obligations, ordinary business records get purged on ordinary schedules. Electronic logs, dispatch messages, maintenance records, telematics data and camera footage all run on clocks of their own, some measured in days.
Which is why a written evidence preservation demand is the first document I send in a truck case — before the medical picture is clear, before anyone has talked about value. A file preserved because somebody asked in writing can be examined. A file that quietly aged out is an argument nobody gets to have.
Why my clients call me for these
Truck cases are not big car cases. They are regulatory cases, won by a lawyer who knows which documents exist, demands them before they disappear, and will put a carrier's own hiring file in front of a jury. I have recovered more than $23 million for injured people and their families, with a top result of $5.4 million, and my clients describe that fight in many five-star reviews. My firm was voted Best of Omaha for personal injury law in 2025 and 2026.
