A traumatic brain injury is one of the most devastating outcomes of a truck crash — and one of the most frequently missed in the critical early days. Because the forces in a truck collision are so extreme, even occupants who “walk away” can suffer a brain injury that changes their life. Here’s what you need to know about TBI after a Michigan truck accident.
What is a traumatic brain injury?
A TBI is damage to the brain caused by a sudden blow, jolt, or penetrating injury. In a crash, it can happen when the head strikes an object — or even without direct impact, when the violent motion causes the brain to move inside the skull. TBIs range from “mild” concussions to severe, permanent brain damage, but even a “mild” TBI can have serious lasting effects.
How truck crashes cause TBI
The enormous energy of a commercial-truck collision makes head and brain injuries especially likely. Rapid acceleration and deceleration, being struck by debris, air-bag impact, and the head hitting the window or steering wheel can all cause a brain injury. The greater the forces, the greater the risk — which is why truck crashes produce so many TBIs.
Levels of severity
Doctors generally classify TBIs as mild (including most concussions), moderate, or severe, based on factors like loss of consciousness and cognitive effects. Importantly, “mild” refers to the initial presentation, not the long-term impact — a “mild” TBI can still cause persistent, disabling symptoms.
Warning signs and symptoms
TBI symptoms can appear immediately or emerge over hours and days:
- Headaches, dizziness, or nausea
- Confusion, memory problems, and trouble concentrating
- Sensitivity to light or noise
- Mood changes, irritability, anxiety, or depression
- Sleep disturbances
- In severe cases, loss of consciousness, seizures, or worsening confusion
Because these overlap with stress and exhaustion, they’re easy to dismiss — which is dangerous.
Why TBIs are so often missed
In the chaos after a crash, adrenaline masks symptoms, and a person may seem fine at the scene. Standard imaging like a CT scan doesn’t always reveal a mild TBI. As a result, brain injuries are frequently undiagnosed at first — which is why anyone in a serious truck crash should be evaluated promptly and watch for delayed symptoms in the days that follow.
Long-term effects and the cost of care
Serious TBIs can permanently affect memory, concentration, judgment, personality, and the ability to work. Care may include hospitalization, neurology, neuropsychological evaluation, cognitive and physical rehabilitation, medication, and long-term support. These costs — especially future care and lost earning capacity — can be enormous, which is why accurately valuing a TBI claim requires medical and economic experts.
How TBI affects your case value
Because of their severity and permanence, TBIs are among the highest-value truck-accident injuries. A TBI will typically clear Michigan’s serious injury threshold, opening the door to a claim against the trucking company for pain, suffering, and losses beyond PIP.

Proving a brain injury
TBI claims are proven with medical evidence: imaging where available, neuropsychological testing, treating-physician opinions, and documentation of how the injury affects daily life — often supported by testimony from family and coworkers about the changes they’ve witnessed. Consistent treatment and follow-up are essential, because insurers aggressively dispute brain injuries they claim aren’t “objectively” shown.
How Michigan No-Fault applies
Your PIP benefits pay for reasonably necessary TBI treatment regardless of fault, while the liability claim against the trucking company compensates for the human cost. Given how expensive lifetime TBI care can be, and how the 2019 reform may cap PIP coverage, the liability claim is often critical to making a brain-injured victim whole.
Frequently asked questions
My CT scan was normal — does that mean I don’t have a TBI? Not necessarily. Some brain injuries don’t show on standard imaging; specialized testing may be needed.
How long do TBI symptoms last? It varies widely — some resolve, others are permanent. Prompt, consistent care gives the best outcome and documents your claim.
Is a concussion a TBI? Yes — a concussion is a form of mild TBI and should be taken seriously.
