Spoliation Letters: Preserving Truck Accident Evidence
Truck-crash evidence sits in different hands and follows different retention rules. A targeted preservation request identifies what matters, documents notice, and asks the right custodians to suspend routine deletion.
Key Takeaways
- Duty and Notice: The preservation duty generally arises when litigation is reasonably anticipated. A letter documents notice and defines the evidence requested.
- Different Retention Rules: ELD records and backups have a six-month federal minimum. ECM events, video, telematics, and messages may be different.
- Target the Custodians: Identify who likely possesses each category of evidence and tailor the request to that person or organization.
- Remedies Are Not Automatic: Courts examine duty, relevance, prejudice, culpability, and the governing state or federal standard.
Why Evidence Preservation Matters
Relevant evidence may be spread across the carrier, driver, owner, broker, repair facility, insurer, technology vendors, and public agencies. Routine retention systems can continue unless the material and custodians are identified promptly.
Records Can Change
A prompt, specific request helps identify relevant systems before ordinary retention processes affect available records.
Notice Documented
A clear request documents what evidence was identified, who received notice, and when the request was made.
Tests the Accounts
Preserved records can confirm, refine, or contradict the accounts given after a crash.
Routine Systems Still Matter
Automatic deletion, vehicle repair, module replacement, camera overwriting, and ordinary document schedules can affect evidence regardless of who ultimately bears fault. A useful request names the systems and asks that specified routines be suspended.
What Evidence to Preserve
A useful preservation request identifies the evidence and systems reasonably tied to the crash, including material that may not be obvious at first.
The truck-crash evidence matrix maps each major record category to the likely holder, known retention risk, and first preservation action.

Who Should Receive a Preservation Letter
Multiple parties may possess different records. The recipient list should be built from ownership, contracts, technology providers, the police report, and the load documents.
| Recipient | Why They Get a Letter |
|---|---|
| Motor Carrier | May control the truck, driver files, ELD records, dispatch data, and maintenance records |
| Driver | May possess a phone, dash camera, messages, photos, or other relevant evidence |
| Freight Broker | May possess load-assignment, contract, selection, and communication records |
| Insurance Carrier | May possess nonprivileged photos, statements, inspections, or other investigation material |
| ELD or Telematics Provider | May possess provider-side records, depending on the service and retention terms |
| Leasing Company | If truck is leased, may have maintenance and inspection records |
Provider-side evidence: An ELD or telematics vendor may possess relevant records, but availability depends on the product, contract, retention policy, and legal process. Preserve first; confirm possession before making assumptions.
Critical Timing Windows
Different evidence follows different rules and business schedules. The dates below distinguish the federal ELD minimum from records whose retention must be confirmed.

VariesOur Practice
When preservation is warranted, we identify the likely custodians and systems early, tailor the request to the crash, and arrange inspection or formal process when a letter alone is not enough.
Possible Remedies for Lost Evidence
A court first determines whether evidence should have been preserved, whether it was lost, whether it can be restored or replaced, and what prejudice or intent the record supports. The remedy must fit the governing standard.
Adverse Inference Instruction
In federal court, an adverse inference for lost electronically stored information requires a finding that the party acted with intent to deprive another party of the information's use. Other forums apply their own standards.
Monetary Sanctions
A court may award expenses or impose other measures when authorized and supported by the record. The amount and basis are case-specific.
Exclusion of Evidence
A court may limit proof or permit curative evidence when the governing rule and degree of prejudice support that response.
Default Judgment
Terminating sanctions are exceptional and require the findings demanded by the governing law. A preservation letter does not guarantee that result.
