Evidence Needed After a Michigan Truck Accident

A commercial truck crash can disrupt your life in a single afternoon. While you receive treatment and try to understand your Michigan truck accident claim, the trucking company and its insurer may already be collecting information about the collision.

Much of that evidence remains under the company’s control. The carrier may repair the truck or return it to service, which could overwrite some electronic data. Federal regulations generally require carriers to retain driver logs and supporting documents for only six months, although other records follow different retention periods.

At Matz Injury Law, we treat evidence preservation as an immediate priority. We send preservation demands and work to secure electronic truck data, driver logs, inspection records, and other company documents before they disappear. That early work can help us establish what happened and protect your right to pursue compensation.

What Evidence Do You Need After a Michigan Truck Accident?

Much of the evidence in a truck accident claim does not appear at the scene. The truck’s electronic systems and the company’s business records may contain information that helps explain why the crash occurred. Evidence in a Michigan truck accident case may include:

• Electronic truck data showing speed, braking, throttle use, engine activity, and other recorded information
• Driver logs showing driving time and on-duty hours
• Company records involving hiring, training, maintenance, dispatch, and cargo
• Crash-scene photos, dashcam video, and nearby surveillance footage
• Statements from people who witnessed the crash
• Medical records connecting your injuries and treatment to the collision

We identify which records matter and take steps to preserve them before repairs, continued truck operation, or routine recordkeeping practices affect their availability.

What Electronic Data and Driver Logs Can Reveal

Electronic truck data can help reconstruct the collision, while driver logs can reveal fatigue or hours-of-service violations. Each source answers different questions about what happened.

The Truck’s Electronic Data

Commercial trucks may store crash-related information in an engine control module or another onboard system. Based on the truck and its equipment, the available data may include speed, braking, throttle position, engine activity, and other details from shortly before the collision.

Continued operation, repairs, or routine data management can alter or overwrite some records. We seek to preserve and download the available information promptly.

The Driver’s Electronic Logs

An electronic logging device records driving time and tracks the driver’s duty status. These records can show how long the driver worked before the crash and whether the driver or trucking company violated federal hours-of-service limits intended to reduce fatigue-related risks.

Federal hours-of-service rules generally require a trucking company to retain a driver’s records of duty status and supporting documents for six months. After that period, the hours-of-service rule no longer requires continued retention. However, a duty to preserve relevant evidence may extend beyond six months when the company reasonably anticipates a claim or lawsuit.

Why This Evidence Disappears and How a Preservation Letter Protects It

A preservation letter, sometimes called a spoliation letter or litigation-hold letter, identifies evidence related to the crash and demands that the trucking company, its insurer, and other recipients retain any evidence in their possession or control. It also documents when each recipient learned about the potential claim.

Without early preservation, routine business practices may put records at risk. Retention periods expire, trucks return to service, and repairs or continued operation may alter electronic data.

Michigan law requires a potential litigant to preserve evidence it knows or reasonably should know relates to future litigation. A preservation letter does not create that duty on its own, but it helps establish notice and identify what the recipient should retain. If a party loses or destroys relevant evidence without a reasonable excuse, the court may impose sanctions or allow an adverse inference, depending on the circumstances.

How We Preserve Evidence for Your Truck Accident Claim

You should not have to locate a commercial truck, arrange an electronic data download, or pursue company paperwork while recovering from your injuries. We handle those tasks and begin identifying evidence as soon as we take the case.

Our attorneys may:

• Send targeted preservation letters to the trucking company, its insurer, and other parties with relevant evidence
• Seek an inspection and download of the truck’s electronic data before repairs or continued operation affect it
• Request driver logs and company records, then use subpoenas after filing a lawsuit when necessary
• Consult an accident reconstruction professional when the available evidence requires technical analysis

Early legal involvement gives us time to identify records, communicate with the appropriate parties, and pursue information through formal discovery when necessary.

Michigan’s no-fault system generally provides personal injury protection benefits through the insurer responsible under the state’s priority rules, regardless of fault. A claim against the truck driver, trucking company, or another responsible party requires evidence of fault, causation, and damages.

Michigan allows non-economic damages for death, permanent serious disfigurement, or serious impairment of body function. A person who bears more than 50% of the fault cannot recover non-economic damages. You may pursue certain economic losses beyond no-fault benefit limits without meeting that injury threshold, although comparative fault can reduce the recovery.

While we investigate, keep copies of your crash photos, police report, medical paperwork, and witness information. Before giving a recorded statement to the trucking company’s insurer, consider discussing the request with a lawyer.

Frequently Asked Questions About Truck Accident Evidence

How Long Do I Have to File a Truck Accident Claim in Michigan?

Michigan generally gives you three years from the crash date to file an injury lawsuit. PIP claims follow separate deadlines. You generally must provide written notice within one year, and the one-year-back rule limits recovery for older unpaid benefits, subject to statutory exceptions and tolling.

What Happens If the Evidence Was Already Lost or Overwritten?

Your claim may still have support from photos, witness statements, video, medical records, and other evidence. If someone failed to preserve relevant information after a preservation duty came into effect, we can ask the court for an appropriate remedy. The result depends on why the evidence disappeared and how its loss affected the case.

Is a Police Report Enough to Prove My Truck Accident Claim?

A police report provides a starting point, but it rarely contains electronic truck data, driver logs, company records, or complete medical evidence. We use the report alongside other available proof to establish fault, connect the crash to your injuries, and document your losses.

Does It Cost Anything to Investigate and Preserve the Evidence?

You pay nothing upfront for our investigation, and the initial consultation is free. We charge 22% of the recovery, while Michigan court rules cap contingency fees in personal injury cases at 33%. You owe nothing unless we recover compensation for you. Our written agreement explains how we handle case expenses.
