After a crash on US-131 or a rear-end collision on 28th Street near the Woodland Mall, most people are focused on getting medical help, calling family, and figuring out what just happened. Evidence is probably the last thing on their mind. That’s understandable. But from a legal standpoint, what gets collected in the hours and days after a crash can shape everything that follows.
Our experienced personal injury attorneys at Gruel Mills work with injured people throughout Kent County and West Michigan, and one thing we’ve seen consistently is that the strength of a vehicle accident claim often comes down to the quality of the evidence supporting it. Michigan law requires the injured person to establish negligence, causation, and damages. Without solid documentation, even a serious injury may be contested or undervalued. So here are the types of evidence that tend to matter most in these cases.
A Police Report Is Just The Starting Point
When law enforcement responds to a crash, the responding officer documents the scene, records statements from drivers and witnesses, notes any apparent traffic violations, and may make an initial determination about fault. That report becomes one of the first pieces of evidence in a Michigan car accident claim.
It is not the final word on liability. Insurance companies and attorneys will scrutinize it, and it can be challenged. But it carries real weight, especially in the early stages of a claim. If police were not called to your accident scene, that gap can create complications later. We encourage clients to always involve law enforcement when there are injuries or significant damage involved.
Photos and Video from the Scene
Photographs of vehicle damage, skid marks, road conditions, traffic signals, and visible injuries can be used in court in Michigan. If you are physically able to do so after a crash, document everything you can see before vehicles are moved. The scene changes quickly.
Surveillance footage is another layer of evidence. Businesses along corridors like Alpine Avenue NW or the I-196 interchange area often have cameras covering parking lots and driveways. That footage can capture a crash in real time, and it can be far more persuasive than any verbal account. The challenge is that video footage gets overwritten. Businesses often retain recordings for only a short period, sometimes as few as 30 to 72 hours. Once it’s gone, it’s gone.
Witness memories follow the same pattern. People forget details, move away, or become harder to reach. Prompt action following an accident genuinely reduces the risk of losing this kind of critical evidence.
The Vehicle’s Black Box Data
Most modern vehicles contain what is commonly called a “black box,” formally known as an event data recorder, or EDR. These devices record what the vehicle was doing in the seconds immediately before and during a crash, including vehicle speed, brake application, steering input, throttle position, airbag deployment, and seatbelt status.
That data can be extraordinarily useful when liability is disputed. If the other driver claims they were not speeding, the EDR may tell a different story. Michigan courts have treated this data as admissible evidence, and in serious cases, Michigan State Police may download it as part of their investigation. In most smaller crashes, though, that does not happen automatically. Your attorney may need to take steps to preserve and retrieve it.
EDRs typically operate on a loop. Once a vehicle is driven again after a crash, that data may be overwritten. In some systems, the window is days. In others, it may be shorter. This is one of the concrete reasons why reaching out to an attorney early matters, not as a formality, but as a practical step to preserving evidence that could otherwise disappear.
Medical Records and Treatment Documentation
Medical records serve two purposes in a car accident case. First, they document the nature and severity of your injuries. Second, they help establish the connection between the crash and those injuries. That connection, what lawyers call causation, is something the other side will often challenge.
Gaps in treatment are a common problem. If someone waits weeks to see a doctor after a crash, insurers may argue the injuries were not serious or were caused by something else entirely. We advise clients to seek medical attention promptly after any accident, even when injuries seem minor at first. Some conditions, like soft tissue damage or concussions, do not present their full picture right away.
Economic damages in Michigan car accident cases, including medical bills, lost wages, future care costs, and out-of-pocket expenses, are documented through medical records, employment records, and related financial documentation. The more thorough and consistent the record, the stronger the foundation for your personal injury claim.
Witness Statements
Eyewitnesses to a crash can provide accounts of what they saw, including driver behavior leading up to the impact. A bystander who watched a driver run a red light at the Wealthy Street interchange or saw someone drifting across lanes on I-96 may have information that no other evidence can replicate.
Getting witness contact information at the scene is valuable. Statements taken close in time to the crash tend to be more reliable than recollections gathered weeks or months later. Witness memories fade, details blur, and people become harder to locate. If there were witnesses at your accident scene, their information should be preserved as quickly as possible.
Accident Reconstruction in Complex Cases
Not every case requires this, but in crashes involving serious injuries, disputed liability, or complex circumstances, accident reconstruction may become a necessary aspect of the case. Reconstruction professionals use physics, vehicle data, road evidence, and other materials to recreate what happened. They can offer opinions about speed, point of impact, and driver behavior that go beyond what photographs or witness accounts can establish alone.
In a car accident case, reconstruction is specifically about establishing the sequence of events and assigning fault. Medical experts who are called to testify may also offer opinions about the severity of injuries and their long-term effects. Economic analysts can calculate projected lost wages. These professional opinions can reinforce a claim when liability or damages are disputed.
Your Own Records and Documentation
One category of evidence that often gets overlooked is the personal documentation an accident victim should create and maintain after a crash. A written record of how injuries have affected your ability to work, complete household tasks, or participate in activities you previously enjoyed provides your attorney with additional material to support a claim for non-economic damages, like pain and suffering.
Michigan law sets a threshold for recovering non-economic damages. The injured person generally must show that their injuries have affected their ability to live their normal life in an objectively demonstrable way. Personal journals, photographs of physical limitations, and consistent statements to treating physicians all contribute to building that picture.
Call Gruel Mills Before Time Runs Out
Michigan law generally provides a limited window of time from the date of a crash to file a personal injury lawsuit. Missing a deadline can mean losing the right to pursue compensation entirely, regardless of how strong the underlying evidence might be.
Most people hire lawyers too late. Not only may your right to sue pass, but evidence may be gone by the time you realize that you will need long term care for your injuries. An early consultation with a lawyer prevents problems that cannot always be fixed later.
If you or someone you care about has been injured in a crash in the Grand Rapids area, including accidents on US-131, M-6, or any of the roads throughout Kent County, contact Gruel Mills to discuss what happened and learn what your options may be. Personal injury cases are handled on a contingency basis, which means you pay no lawyer fees unless we obtain compensation for you.
