The Preservation Letter That Decides a Truck Case by Day 30
Federal rules tell trucking companies how long to keep their records, and the honest answer is: not long.
Driver inspection reports can be lawfully destroyed after three months.
Driver logs can go after six.
The truck itself can be repaired, sold, or scrapped whenever the carrier likes.
A spoliation letter is the formal demand that stops all of it, and it is the first thing that should happen in a serious truck case.
Nothing in a truck case is more perishable than the proof, and the other side is the one holding it.

At-a-Glance: Evidence Preservation in a Truck Case
- The duty to preserve evidence begins when litigation is reasonably foreseeable, and the letter makes that date undeniable
- Every case we take is prepared as if the preservation fight will end up in front of a judge
- Destroyed evidence can earn the carrier court sanctions, including a jury instruction that the missing proof was unfavorable
What a Spoliation Letter Is and What It Legally Obligates
A spoliation letter, sometimes called a preservation letter or litigation hold demand, is written notice to the carrier, its insurer, and anyone else holding evidence that a claim is coming and that specific categories of evidence must not be altered or destroyed.
The legal duty it invokes already exists: a party that knows litigation is reasonably foreseeable must preserve relevant evidence. What the letter adds is proof of knowledge, a written demand naming the crash, the truck, and the records, with a date on it.
Sent within days of the crash, it reaches the records while they still exist. Sent after the first settlement call months later, it often arrives at an empty filing cabinet.
Carriers do not have to destroy evidence in bad faith. The retention rules do it for them, politely and on time. The first document we send in a truck case is usually not a demand for money. It is the letter that takes away the carrier's right to shred on schedule. A carrier that receives our preservation letter in week one has a choice to make, and either answer helps us: produce the records, or explain to a judge why they are gone.
The Evidence a Preservation Letter Demands From a Motor Carrier
The letter is written against the federal retention rules, because those rules are the destruction schedule the carrier will otherwise follow.
Driver logs and supporting documents. Hours-of-service records and the documents that verify them must be kept for only six months from receipt.[1] The electronic logging device data behind them is the version worth preserving, because paper summaries can be edited and the device record is harder to dress up.
Driver vehicle inspection reports. The daily defect reports drivers file on their trucks, and the certifications that repairs were made, can be destroyed after three months.[2] In a brake or equipment case these are often the whole story.
Maintenance and repair records. Kept for one year where the vehicle is housed, and only six months after the carrier gives up control of the truck.[3] Selling the tractor starts a clock on its history.
The vehicles themselves. The tractor, the trailer, and the engine control module they carry. A truck returned to service overwrites its own data with every mile, which is why the black box download has to be demanded before the wheels turn.
Post-crash drug and alcohol test results, or the federally required record explaining why no test was done.
Dispatch and communications records. Load assignments, delivery windows, messages between dispatch and the cab, and the bills of lading that show what schedule the driver was actually running.
Camera footage. Inward and outward dashcams, terminal yard cameras, and any third-party footage the carrier collects, which is routinely overwritten in days.
The list flexes with the case. A cargo-shift wreck adds the load documents and securement equipment. A hiring case adds the qualification file and the background investigation behind it.
What Happens When a Carrier Destroys Evidence Anyway
Spoliation is the legal term for destroying or failing to preserve evidence a party was obligated to keep. Courts do not treat it as a paperwork problem.
In federal court, Rule 37(e) governs lost electronic evidence and lets a judge order curative measures when a party failed to take reasonable steps to preserve it. Where the destruction was intentional, the court can instruct the jury to presume the lost evidence was unfavorable, or in extreme cases enter judgment against the destroying party.[4] State courts apply their own versions of the same idea, and some states also recognize separate spoliation claims. The details vary by jurisdiction; the direction does not.
An adverse-inference instruction changes a trial. The carrier that shredded the inspection reports no longer gets to argue the brakes were fine. The jury is told it may assume the destroyed records said otherwise.
"A preservation letter does two jobs. It saves the evidence, and if the carrier destroys it anyway, it turns the destruction itself into proof."
Why the First Thirty Days Decide What a Truck Case Can Prove
Add the clocks up. Camera footage overwrites in days. Electronic control module data can be lost the next time the truck is driven or repaired. Inspection reports become lawful shredder-feed at three months, logs at six, and the truck itself can leave the carrier's control at any moment. Meanwhile the carrier's rapid-response team is often at the crash scene the same day, photographing and downloading for the defense.
Your lawsuit's filing deadline runs in years under your state's statute of limitations, and waiting even a fraction of that time can cost the case its best proof. The claims that settle well are the ones where the evidence was locked down before anyone discussed money. That is also why the preservation demand is drafted to support the liability theories that come later, from driver error to negligent hiring and retention claims built on the carrier's files.
Spoliation Letters and Truck Accident Evidence: Frequently Asked Questions
- Q: How fast should a spoliation letter go out after a truck crash?
-
A: Within days. Camera footage and electronic data can be gone inside a week, and the shortest federal retention periods are measured in months. The letter should reach the carrier before the truck is repaired, the data is overwritten, or the routine destruction schedule catches the records that matter.
- Q: Is a trucking company allowed to destroy records after a crash?
-
A: Not once litigation is reasonably foreseeable, and a serious injury crash usually makes it foreseeable on the spot. The federal retention rules set minimums for ordinary operations, not permission slips for destroying evidence of a known claim. A preservation letter removes any doubt about what the carrier knew and when.
- Q: What if the evidence was already destroyed before I hired a lawyer?
-
A: The case does not automatically end. Courts can sanction spoliation, including instructing the jury to presume the missing evidence was unfavorable to the carrier, and much of the story can be rebuilt from other sources: the other vehicles' data, third-party cameras, witness accounts, and records held by shippers and brokers. But every week of delay narrows those options.
- Q: Can I send a preservation letter myself?
-
A: You can, and a prompt letter from anyone beats silence. The risk is scope: a demand that misses the supporting documents, the telematics, or the trailer's separate owner leaves those doors open. Letters drafted against the federal regulations, naming each record and its retention rule, are much harder to evade. The consultation that gets one out the door is free.
