What Is a Spoliation Letter? Preserving Evidence After a Crash

A spoliation letter is a written demand that someone keep evidence instead of destroying, altering, or losing it. After a truck accident it is usually the first thing a lawyer sends, because the trucking company holds most of the evidence and is allowed to discard some of it within months.

The short version:

• “Spoliation” means destroying or failing to preserve evidence that matters to a legal claim. The letter puts the other side on notice not to.
• It is also called a preservation letter, a litigation hold letter, or an evidence preservation demand.
• In truck cases timing is the whole point. Federal rules let carriers discard driver logs after six months.
• If evidence is destroyed after a proper letter, a court can penalise the party that destroyed it.

This is general information, not legal advice. Evidence rules and deadlines vary by state and by court.

What a spoliation letter does

The letter does two things. It tells the recipient that a claim is likely, and it lists the evidence they are expected to keep. Once a company knows a claim is coming, it generally has a legal duty to preserve what is relevant. The letter removes any argument that it did not know.

It does not force anyone to hand evidence over. That happens later, through insurance negotiations or the formal discovery process in a lawsuit. The letter only makes sure the evidence still exists when that time comes.

Why it matters so much after a truck accident

In an ordinary car crash, most of the evidence is at the scene or in the drivers’ phones. In a truck crash, the most important records sit inside the trucking company, and federal regulations set how long it has to keep them:

• Driver logs. Carriers must keep records of duty status and their supporting documents for six months. After that they can lawfully be discarded.
• Maintenance records. Inspection and repair records are kept for one year while the vehicle is with the carrier, and six months after it leaves.
• Driver qualification file. This is kept for as long as the driver is employed and three years afterwards.
• Electronic data. Engine control modules and other onboard devices can overwrite crash data as the truck keeps running, or lose it when the truck is repaired.

A carrier that follows its normal retention schedule is not doing anything wrong, unless it already knows the records are needed for a claim. The letter is what changes that.

What the letter asks them to keep

A thorough letter in a truck case typically lists:

• the truck and trailer themselves, unrepaired, until they can be inspected;
• electronic logging device (ELD) and engine control module (“black box”) data;
• hours-of-service logs and supporting documents such as fuel receipts and bills of lading;
• the driver qualification file, including licence, training, and medical certification;
• post-crash drug and alcohol test results;
• inspection, maintenance, and repair records;
• dispatch records and messages between the driver and the company;
• dashcam or other video, and any GPS or telematics data;
• cargo, loading, and weight records.

Being specific matters. A vague request to “preserve all evidence” is easier to argue about later than a list that names the records.

Who sends it, and when

Usually an attorney sends it, on letterhead, by a method that proves delivery. You are allowed to send one yourself, and a clear written demand is better than none. A lawyer’s letter tends to be more complete and is taken more seriously.

It goes to the trucking company, and often to its insurer, the driver, and any other company that may hold evidence, such as a maintenance contractor or the shipper.

Send it as early as possible. Days are better than weeks. The six-month retention period for logs sounds generous, but electronic data and the condition of the truck can change within days of the crash.

What happens if evidence is destroyed anyway

Courts treat destroying evidence after notice seriously. What a court can do depends on the state and on whether the case is in state or federal court, but the usual options include:

• telling the jury it may assume the missing evidence would have been bad for the party that destroyed it;
• barring that party from using certain evidence or arguments;
• ordering it to pay costs and fees;
• in extreme cases, deciding the issue or the whole case against it.

In federal court, lost electronic information is governed by Rule 37(e) of the Federal Rules of Civil Procedure, which reserves the harshest penalties for a party that acted with intent to deprive the other side of the information. State courts have their own standards.

Frequently asked questions

Is a spoliation letter the same as a preservation letter?

Yes. Spoliation letter, preservation letter, litigation hold letter, and evidence preservation demand all describe the same thing: a written notice to keep evidence relevant to a likely claim.

Can I send a spoliation letter without a lawyer?

Yes. Nothing requires a lawyer to send it. Put it in writing, be specific about what must be kept, date it, and send it in a way that proves it was received. A lawyer will usually know more precisely which records to name.

How soon after a truck accident should it be sent?

As soon as you can, ideally within days. Some electronic data can be overwritten quickly, and the truck may be repaired and returned to service.

Does the trucking company have to give me the evidence once it gets the letter?

No. The letter requires them to keep it, not to hand it over. Evidence is obtained later through negotiation or through discovery if a lawsuit is filed.

What if I already missed the six-month window?

Some records may be gone, but not all. Driver qualification files and some maintenance records are kept longer, and police reports, witness statements, medical records, and third-party data may still exist. Speak to an attorney about what can still be recovered.
