Investigating and Proving a Commercial Truck Collision Claim: A Practical Checklist

Tort > Trucking and Commercial Motor Vehicles | Published 4 March 2025 - Updated 25 September 2025 | UpLaw - uplaw.us

How to Use This Checklist

Parts 1 and 2 must happen in the first week; nothing else in this document can substitute for them. Parts 3 through 11 unfold over the life of the case. Part 12 is written for the carrier and defense side, and Part 13 applies to everyone.

Doctrine is in the comprehensive guide; the narrative introduction is how truck accident cases are actually built; the forms are in the toolkit.

⚠ The evidence clock is shorter than the limitations clock. Records of duty status: six months under 49 C.F.R. part 395. Maintenance records: one year, and ninety days after the vehicle leaves the carrier under 49 C.F.R. part 396. Camera footage: days, with no regulatory retention at all.

Part 1 — Scene and Vehicle

☐ Get someone to the scene before it is cleared — counsel, an investigator, or a family member with a phone.

☐ Photograph final rest positions, gouge marks, skid and yaw marks, debris field, fluid trails, and roadway markings.

☐ Photograph sight lines from the approach of each vehicle, at the same time of day if possible.

☐ Photograph the tractor and trailer: DOT number, license plates, company name, reflective tape condition, lamps, rear impact guard, tires, and visible damage.

☐ Photograph the trailer before it is washed. Conspicuity tape condition is evidence and is destroyed by routine cleaning.

☐ Record weather, light, and road surface conditions.

☐ Identify every witness and every responding officer, including any commercial vehicle enforcement officer.

☐ Ask whether a post-crash roadside inspection was performed, and obtain the report. It frequently documents out-of-service conditions that appear nowhere else.

☐ Obtain the police report, 911 audio, and dispatch logs before they cycle.

☐ Preserve the injured person's vehicle as well; both sides will want it.

Part 2 — The Preservation Letter

☐ Send within days, to the carrier, the driver, the insurer, the broker, and the shipper.

☐ Cite the regulation for each category so the recipient cannot claim ambiguity.

☐ Demand preservation of:

• records of duty status and supporting documents — 49 C.F.R. part 395;
• the complete driver qualification file — 49 C.F.R. part 391;
• maintenance, inspection, and repair records, including driver vehicle inspection reports — 49 C.F.R. part 396;
• controlled substances and alcohol testing records and clearinghouse queries — 49 C.F.R. part 382 and 49 C.F.R. part 40;
• the accident register and prior incident files — 49 C.F.R. part 390;
• the engine control module data, with a request for a joint download and a written protocol;
• telematics, GPS, forward-facing and driver-facing camera footage, collision mitigation and lane departure event logs;
• satellite and messaging communications between dispatch and driver;
• the bill of lading, load confirmation, trip sheets, fuel receipts, toll records, and scale tickets;
• the tractor and trailer themselves, unrepaired, pending joint inspection.

☐ Name the camera system specifically. A general letter frequently arrives after a looped recording is gone.

☐ Request the identity of every entity with an interest in the equipment and the load.

☐ Send by a method that proves delivery and calendar a follow-up in fourteen days.

Part 3 — Parties and Coverage

☐ Identify from the bill of lading and load confirmation: the shipper, the broker, the carrier of record, the carrier whose authority was used, the tractor owner, the trailer owner, and any lessor.

☐ Pull public registration and insurance filings for each carrier and broker.

☐ Pull the carrier's roadside inspection and crash history under 49 C.F.R. part 385.

☐ Request the complete policy including the declarations, the schedule of covered autos, and all endorsements.

☐ Look for the MCS-90 endorsement required by 49 C.F.R. part 387 and 49 U.S.C. § 31139.

☐ Identify excess and umbrella layers and any self-insured retention.

☐ Ask whether non-trucking or bobtail coverage is implicated, and whether the driver was under dispatch.

☐ Evaluate broker liability and the preemption defense under 49 U.S.C. § 14501, reading Rowe v. New Hampshire Motor Transport Association, 552 U.S. 364, and the governing circuit rule.

☐ Check the statutory remedy at 49 U.S.C. § 14704 and definitions at 49 U.S.C. § 13102.

Part 4 — Hours of Service

☐ Obtain the ELD data in native format with the audit trail, not a printed summary.

☐ Obtain the supporting documents 49 C.F.R. part 395 requires the carrier to keep.

☐ Subpoena third-party records with independent timestamps: fuel card transactions, toll transponder data, weigh station records, delivery receipts, and repair invoices.

☐ Build a timeline comparing logged status against every independent data point.

☐ Check each limit: eleven-hour driving; fourteen-hour window; thirty-minute break; sixty-in-seven or seventy-in-eight; and any restart.

☐ Verify any claimed exception — short-haul, adverse driving conditions, sleeper berth splitting — actually met its conditions.

☐ Obtain dispatch communications and look for scheduling that could not be met inside the limits.

☐ Check the fatigue prohibition in 49 C.F.R. part 392, which binds the carrier as well as the driver.

Part 5 — Driver Qualification

☐ Obtain the full file under 49 C.F.R. part 391, component by component.

☐ Check the employment application for a complete ten-year history and unexplained gaps.

☐ Check for written inquiries to every prior employer, and for responses. Subpoena the prior employers directly.

☐ Check the motor vehicle records from every state where the driver was licensed in the preceding three years, at hire and annually.

☐ Check the annual review of driving record and the written evaluation.

☐ Check the medical examiner's certificate, its currency, and any restrictions.

☐ Check the road test certificate or equivalent.

☐ Check CDL status and any disqualification under 49 U.S.C. § 31310, 49 C.F.R. part 383, and 49 C.F.R. part 384.

☐ Obtain the driver's personnel and disciplinary file, training records, and scorecards.

Part 6 — Equipment and Maintenance

☐ Obtain the maintenance file under 49 C.F.R. part 396, including the systematic program, annual inspections, and repair orders.

☐ Obtain driver vehicle inspection reports for the ninety days preceding, and match reported defects to repair orders.

☐ Check equipment requirements under 49 C.F.R. part 393: brakes, lamps, reflective devices, rear impact guard, coupling devices, tires, and cargo securement.

☐ Obtain the post-crash inspection report and any out-of-service determination.

☐ Arrange a joint physical inspection of the tractor and trailer before repair.

☐ Evaluate a product claim against a component or trailer manufacturer, with attention to preemption; see Freightliner Corp. v. Myrick, 514 U.S. 280, and Product Liability: A Comprehensive Guide to Defects, Warnings, Causation, and Defenses.

☐ For hazardous materials loads, check 49 C.F.R. part 397 routing, attendance, and parking rules.

Part 7 — Testing

☐ Determine whether post-accident testing was required under 49 C.F.R. part 382.

☐ Obtain the results, the chain of custody, and the medical review officer file, with procedures under 49 C.F.R. part 40.

☐ If no test was performed, obtain the documentation of why, which the regulation requires.

☐ Obtain clearinghouse query records at hire and annually.

☐ Obtain the random testing program records and the carrier's selection rates.

☐ Check statutory authority and history at 49 U.S.C. § 31306.

Part 8 — Written Discovery

☐ Draft requests from the regulations, one request per component, so partial production is visible.

☐ Request the categories with no regulatory retention — telematics, GPS, camera, event logs, dispatch messaging, scorecards, safety meeting minutes — and pair them with the preservation demand.

☐ Interrogatories: every entity with an interest in the tractor, trailer, and load; every policy including endorsements; the identity of the dispatcher; every recording system installed on the vehicle; whether post-accident testing occurred and if not, why. See Answering Rule 33 Interrogatories: A Practical Checklist.

☐ Requests for admission narrowing scope of employment, applicability of the regulations, and non-retention of specific records. See Answering Rule 36 Requests for Admission: A Practical Checklist.

☐ Third-party subpoenas to fuel card vendors, toll authorities, prior employers, repair facilities, and cell carriers. See The Subpoena Survival Guide: Rule 45 From All Three Sides.

☐ Negotiate an ESI protocol covering native formats, metadata, and the ELD audit trail. See Civil Discovery: A Comprehensive Guide to Requests, Depositions, ESI, Privilege, and Sanctions.

☐ Negotiate a protective order on scope rather than resisting the concept, preserving trial use.

☐ Move to compel promptly where production is partial; delay compounds. See Moving to Compel Discovery and Seeking Rule 37 Sanctions: A Practical Checklist.

Part 9 — Depositions

☐ The driver: route, schedule, sleep, meals, prior day's activity, dispatch communications, pre-trip inspection, familiarity with the equipment, training received, and the seconds before impact.

☐ The corporate representative under Federal Rule of Civil Procedure 30, with topics listed by regulation so the designation duty is unambiguous.

☐ The safety director: the compliance program, log auditing practices, how violations are addressed, and what the company knew about this driver.

☐ The dispatcher: how the schedule was built, what the driver said, and what pressure was applied.

☐ The maintenance supervisor: the systematic program, deferred repairs, and the specific defects at issue.

☐ The broker's carrier-selection personnel where a selection theory is pleaded.

☐ Prepare with the documents, not from an outline. See Preparing to Take a Deposition: A Practical Checklist and The Federal Deposition Toolkit: From Notice to Trial Testimony.

Part 10 — Spoliation

☐ Document the timeline: when the duty attached, when the letter was sent and received, and when the evidence was lost.

☐ Identify the retention setting for each system, and who had authority to change it.

☐ Determine whether an internal litigation hold issued, when, and to whom.

☐ Analyze the remedy under Federal Rule of Civil Procedure 37(e): curative measures on prejudice; an adverse inference, presumption, dismissal, or default only on a finding of intent to deprive.

☐ Consider state-law remedies where they are broader.

☐ Preserve the record for trial even if sanctions are denied; the loss itself is frequently admissible.

Part 11 — Damages and Resolution

☐ Commission a life care plan early in catastrophic cases; it drives everything.

☐ Retain an economist for present value and earning capacity.

☐ Obtain a vocational assessment.

☐ Document household services and the cost of replacing them.

☐ Identify every lien: health plan, Medicare, Medicaid, hospital, workers' compensation, disability.

☐ Confirm whether damages caps apply and whether they attach to non-economic damages only.

☐ Evaluate punitive damages against the state standard and the corporate evidence developed.

☐ Plan the settlement structure, including any need for benefit preservation. See The Special Needs Trust and Benefit Preservation Toolkit.

☐ Prepare for mediation with the documents, not just the medicals. See Preparing for and Attending a Mediation: A Practical Checklist.

Part 12 — For the Carrier and Defense Counsel

☐ Execute the written post-accident protocol the same day: secure and image the ECM; quarantine the equipment; pull ELD, telematics, camera, and dispatch data; conduct required testing; and issue an internal litigation hold.

☐ Do not return the equipment to service after notice of a claim without documenting an inspection opportunity.

☐ Send your own preservation letter for the other vehicle, the phone, and social media.

☐ Audit compliance immediately and under privilege, so counsel knows what the file says before the plaintiff does.

☐ Investigate comparative fault with the same rigor applied to the carrier.

☐ Separate violation from causation in every analysis and every argument.

☐ Research the admission-of-agency rule in the forum before answering.

☐ Prepare the corporate representative on every regulation, well before the notice arrives. See Defending Depositions in Federal Court: A Comprehensive Guide.

☐ Evaluate early resolution where falsification, coercion, or deferred out-of-service defects appear in the file.

☐ Confirm the coverage tower and whether the MCS-90 is implicated.

Part 13 — Quality Control

☐ Was a preservation letter sent within days, citing each regulation, and is delivery proof in the file?

☐ Was a joint ECM download requested and, if refused, was the refusal documented?

☐ Were third-party records with independent timestamps subpoenaed?

☐ Is the ELD data in native format with the audit trail?

☐ Is the driver qualification file complete, and is every gap documented?

☐ Do driver vehicle inspection reports match repair orders?

☐ Was post-accident testing performed or its absence documented?

☐ Is every potential defendant identified from the shipping paperwork?

☐ Is the complete insurance tower, with endorsements, in the file?

☐ Has the forum's negligence per se and admission-of-agency rule been researched in writing?

☐ Is causation for each violation stated explicitly, rather than assumed?

☐ Are all liens identified before any distribution?

Part 14 — What Each Document Actually Proves

Checklists of documents are only useful if you know what each one is for. Here is the translation.

The engine control module download. Speed, throttle position, brake application, and hard-braking events in the seconds before impact. It proves or disproves the driver's account of reaction, and it is the single most persuasive piece of evidence in most cases because it is mechanical rather than testimonial. Its limitations — sampling rate, trigger thresholds, tire size calibration — are the defense's cross-examination and should be understood before the plaintiff's expert relies on it.

The electronic logging device record. Duty status over time. Standing alone it proves compliance, because it is generated by the system the carrier controls. Compared against fuel, toll, and delivery records, it proves either corroboration or falsification — and falsification changes the character of the case entirely, because it converts a negligence dispute into a credibility dispute the carrier cannot win.

Dispatch and satellite messages. What the company asked for. A message directing an arrival time that cannot be met within the hours available under 49 C.F.R. part 395 is the corporate liability case in a single document.

The driver qualification file. What the company knew or should have known before it handed over the keys. Missing prior-employer inquiries under 49 C.F.R. part 391 do not merely violate a rule; they establish that the company chose not to learn something it was required to learn.

Driver vehicle inspection reports. What the driver told the company about the equipment, and whether the company did anything. A defect reported three times with no repair order is a maintenance case that requires no expert.

The post-crash roadside inspection. An independent, contemporaneous assessment of vehicle condition by an enforcement officer with no stake in the litigation. It is frequently the most credible document in the file and is often overlooked because it is filed with the state rather than produced by the carrier.

The accident register and prior incidents. Notice and pattern. Relevant to punitive damages and to negligent retention, subject to substantial-similarity analysis and balancing under Federal Rule of Evidence 403.

The safety rating and inspection history. Public data under 49 C.F.R. part 385 that establishes what a broker or shipper could have discovered before tendering the load.

The insurance policy with endorsements. Whether there is money, how much, and — through the MCS-90 under 49 C.F.R. part 387 — whether a judgment is collectible even if coverage fails.

Part 15 — Recurring Errors

⚠ Sending a generic preservation letter. A letter that does not name the camera system, the telematics provider, and the ELD vendor is a letter that will be answered with "we produced everything responsive."

⚠ Accepting a printed log summary. Native data with the audit trail shows edits. A PDF does not.

⚠ Failing to subpoena neutral third parties. Toll and fuel data are the only records in the case that no party controls.

⚠ Litigating the case as an ordinary collision. The medical specials are not the case; the corporate file is.

⚠ Pleading direct negligence claims without researching the admission rule, and losing them along with all the supporting evidence.

⚠ Asserting every violation without connecting any of them to causation, which invites a jury to conclude the plaintiff is reaching.

⚠ For carriers: repairing or selling the equipment after notice. It converts a defensible case into a sanctions hearing.

⚠ For carriers: creating documents after the fact. A file completed post-collision is worse than an incomplete one.

⚠ Missing the trailer wash. Reflective tape condition in an underride case is destroyed by ordinary cleaning within days.

⚠ Ignoring the broker. A separate defendant, separate coverage, and a live legal question under 49 U.S.C. § 14501.

Part 16 — A One-Page Week-One Sequence

1. Someone photographs the scene and the equipment today.
2. Preservation letters go out to carrier, driver, insurer, broker, and shipper by day three, citing each regulation.
3. Request a joint ECM download with a written protocol.
4. Ask that the tractor and trailer be held unrepaired.
5. Order the police report and any post-crash roadside inspection report.
6. Subpoena fuel, toll, and weigh-station records.
7. Pull public safety-rating and insurance filings for every entity on the paperwork.
8. Request the complete policy with all endorsements.
9. Calendar six months for records of duty status and one year for maintenance records.
10. Open a chronology and put every document into it as it arrives.

Part 17 — For the Injured Person and the Family

Much of this checklist is written for lawyers. These items are for the people actually living through it, and they matter as much as anything above.

☐ Get medical care and follow through with it. Gaps in treatment are used to argue that the injury was not serious, and they are the single most common self-inflicted damage to a claim.

☐ Do not give a recorded statement to the trucking company's adjuster without advice. The call will be friendly and the questions will be about your prior medical history.

☐ Do not sign a medical authorization that is broader than the treatment at issue.

☐ Do not post about the collision, your injuries, or your activities on social media. It will be found and used.

☐ Keep a daily journal of pain, limitations, missed activities, and help you needed from others. It becomes the most persuasive evidence of non-economic damages that exists.

☐ Save every receipt — prescriptions, mileage to appointments, equipment, home modifications, and paid help.

☐ Keep the wrecked vehicle until your lawyer says otherwise, and photograph it before storage fees start.

☐ Report to your own insurer promptly, including any uninsured or underinsured motorist coverage. See The Auto Injury and Insurance Claim Toolkit.

☐ Tell your lawyer about every health plan, Medicare, Medicaid, or workers' compensation benefit you received, because those become liens that must be resolved before you are paid.

☐ Ask your lawyer, early: Has a preservation letter gone out? Has an ECM download been requested? Do we know who the broker is? Those three questions tell you whether the case is being handled as a truck case.

☐ Understand the timeline. Serious commercial vehicle cases commonly take one to three years, and the reason is that the corporate evidence takes time to obtain and is what determines value.
