How to Send a Spoliation Letter to a Trucking Company After a Crash in Michigan

When a massive commercial truck collides with a passenger vehicle, the trucking company's insurance investigators are dispatched to the scene almost immediately. Their goal is to minimize liability. The most critical evidence to prove the truck driver was at fault-such as speed data, braking records, and driving hours-is entirely in the hands of the trucking company.

Under Federal Motor Carrier Safety Administration (FMCSA) regulations, trucking companies are only required to keep certain records for a limited time. If you do not formally demand that they preserve this evidence, it can legally be deleted or overwritten. This process is called "spoliation of evidence." Sending a spoliation letter is the very first step in building a strong personal injury claim in Michigan.

Step-by-Step: Sending a Spoliation Letter in Michigan

You cannot simply call the trucking company and ask them to keep the records. You must create a verifiable paper trail that holds up in a Michigan court.

Step 1: Hire a Michigan Truck Accident Lawyer

Due to rigorous evidentiary requirements and federal compliance standards, accident victims are generally advised to work with qualified counsel rather than drafting a preservation demand pro se. A local attorney from our US Lawyers Directory will know exactly which federal and state regulations to cite. They will also be able to file the claim in the appropriate jurisdiction, such as the Wayne County Circuit Court, Detroit or the Kent County Circuit Court, Grand Rapids.

Step 2: Identify All Corporate Entities

Trucking operations are often a web of different companies. The cab might be owned by one company, the trailer by another, and the driver employed by a third-party staffing agency. Your lawyer will investigate to ensure the spoliation letter is sent via certified mail to all registered agents involved.

Step 3: Draft and Send the Certified Letter

The letter must explicitly list every piece of evidence to be preserved. It must be sent via Certified Mail with a Return Receipt Requested to prove that the company received it. This puts them on legal notice.

Step 4: File a Lawsuit to Force Compliance

If the trucking company ignores the letter or attempts to tamper with the evidence, your lawyer will file a formal lawsuit. They will use Form MC 01, Michigan, State Court Administrative Office, Summons, and ask the judge for a temporary restraining order to seize the truck and its data.

Critical Evidence to Preserve

A standard car accident involves photos and police reports. A commercial truck crash involves highly technical data systems.

Securing the ECM (Black Box) Data

The Electronic Control Module (ECM) acts as the truck's black box. It records the truck's speed, whether the brakes were applied, throttle position, and engine RPMs in the seconds leading up to the crash. Because trucks are driven daily, this data can quickly be overwritten by new driving data if the truck is put back on the road. The spoliation letter demands the truck be grounded until the ECM is downloaded by a forensic expert.

Demanding Dashcam and Cabin-Cam Footage

Many modern fleets use inward-facing and outward-facing cameras. The outward camera shows exactly what the driver saw, proving if they ran a red light or drifted lanes. The cabin-cam proves if the driver was texting, asleep, or distracted. This video footage is often stored on cloud servers and is routinely deleted after 30 to 60 days unless a preservation letter is received.

Preserving Hours of Service (HOS) Electronic Logs

Driver fatigue is a leading cause of truck crashes. Under 49 C.F.R. § 395.8, drivers must log their driving hours electronically to ensure they are not driving beyond legal limits. However, trucking companies are only required to keep these logs for six months. Your letter ensures these logs, along with fuel receipts and toll tickets (to verify the logs' accuracy), are kept permanently for trial.

Impounding the Physical Cab for Inspection

Sometimes, the crash is caused by poorly maintained brakes or blown tires. A spoliation letter demands that the physical condition of the truck remains completely unaltered. The trucking company cannot repair the brakes, replace the tires, or scrap the cab until your independent mechanical expert conducts a full inspection.

Michigan's Stance on Spoliation of Evidence

Michigan courts take the destruction of evidence very seriously. If a trucking company receives your spoliation letter and destroys the ECM data anyway, your lawyer can ask the judge for an adverse inference jury instruction. As established in the precedent Brenner v. Kolk, 226 Mich. App. 149 (MI Court of Appeals 1997), if a party intentionally destroys evidence, the jury is instructed to assume that the destroyed evidence would have proven the trucking company was at fault.

How Much Does it Cost in Michigan?

Sending a spoliation letter and launching a truck crash investigation involves specialized experts, but you generally do not pay upfront.

How Long Does the Process Take?

A spoliation letter should be sent within days, ideally within 48 to 72 hours of the crash. Once the letter is received, the physical inspection of the truck and the downloading of data can usually be arranged within 2 to 4 weeks. Resolving a commercial truck accident lawsuit, however, often takes anywhere from 1 to 3 years due to the high insurance policy limits and complex liability issues.
