Can You Sue the At-Fault Driver After a Michigan Car Accident?

One of the most common questions I hear from car accident victims in Michigan is: “Can I sue the person who hit me?”

It sounds like it should be simple. Someone ran a red light, rear-ended you, or crossed the center line — and now you’re dealing with serious injuries. In most states, you’d file a lawsuit against the at-fault driver and move on. But Michigan isn’t most states.

Michigan’s No-Fault insurance system works differently, and understanding the rules can mean the difference between getting compensated for your pain and suffering or walking away with nothing beyond your PIP benefits.

Michigan Is a No-Fault State — What Does That Mean?

Under Michigan’s No-Fault Act (MCL 500.3101 et seq.), your own auto insurance company pays for your medical bills, lost wages, and other expenses after an accident — regardless of who caused the crash. These are called Personal Injury Protection (PIP) benefits, and they’re one of the most generous benefit packages in the country.

But here’s the tradeoff: because the No-Fault system covers your economic losses, Michigan limits your ability to sue the other driver. You can’t just file a lawsuit because someone caused your accident. You have to meet a specific legal threshold first.

The “Serious Impairment of Body Function” Threshold

Under MCL 500.3135, you can only sue the at-fault driver for non-economic damages (pain and suffering, emotional distress, loss of enjoyment of life) if you suffered a “serious impairment of body function.”

The statute defines this as “an objectively manifested impairment of an important body function that affects the person’s general ability to lead his or her normal life.”

That’s a lot of legal language. Let me break it down into the three elements a court will look at:

Objectively manifested — Your injury must be observable or detectable through medical evidence. MRIs, X-rays, medical records, and clinical findings all count. Purely subjective complaints of pain, without supporting medical documentation, may not be enough on their own.
Important body function — The injury must affect a body function that matters. This is interpreted broadly by Michigan courts — your spine, brain, limbs, vision, mobility, and cognitive function all qualify. Most legitimate injuries meet this element.
Affects your general ability to lead your normal life — This is where most cases are won or lost. The court compares your life before the accident to your life after. Can you still work? Exercise? Play with your kids? Do household chores? Drive comfortably? If the accident has genuinely changed how you live your daily life, this element may be satisfied.

What Injuries Typically Meet the Threshold?

Every case is different, but here are examples of injuries that often qualify:

Herniated or bulging discs in the neck or back, especially when they require surgery or ongoing treatment
Traumatic brain injuries (TBIs), including concussions with lasting cognitive effects
Broken bones that require surgery, hardware, or extended recovery
Torn ligaments (ACL, rotator cuff, meniscus) requiring surgical repair
Chronic pain conditions that develop after the accident and are supported by medical evidence
Scarring or disfigurement

On the other hand, minor soft tissue injuries that resolve within a few weeks — while painful and real — may not meet the threshold if they don’t significantly impact your daily life over a longer period.

What About Death or Permanent Disfigurement?

Michigan law also allows a lawsuit against the at-fault driver if the accident caused death or permanent serious disfigurement. These are separate grounds under the same statute, and they don’t require the same “serious impairment” analysis.

Who Decides Whether You Meet the Threshold?

This is an important question. Whether your injury meets the serious impairment threshold can be decided by either a judge or a jury, depending on the facts.

If the facts are straightforward and not in dispute, the judge may decide the issue as a matter of law — which means the insurance company can file a motion to throw out your case before it ever reaches a jury. This happens more often than people realize, and it’s one of the reasons having an experienced attorney matters so much in Michigan car accident cases.

When the facts are disputed — when reasonable people could disagree about whether your injury affects your normal life — the question goes to the jury.

What Damages Can You Recover If You Meet the Threshold?

If your injury qualifies, you can pursue a third-party lawsuit against the at-fault driver (or their insurance company) for:

Pain and suffering
Emotional distress
Loss of enjoyment of life
Loss of consortium (for your spouse)
Excess economic damages not covered by your PIP benefits

These damages can be significant. While PIP benefits cover your medical bills and a portion of lost wages, they don’t compensate you for the human cost of your injuries — the sleepless nights, the activities you can no longer enjoy, the toll on your relationships and mental health.

Why You Need an Attorney Who Understands Michigan No-Fault Law

The threshold requirement makes Michigan car accident cases more complex than in most other states. Insurance companies know this, and they use it to their advantage. They’ll argue your injuries aren’t “serious” enough, that you can still lead a “normal life,” or that your symptoms are pre-existing.

An experienced Michigan auto accident attorney knows how to:

Build a medical record that clearly demonstrates the impact on your life
Gather the right evidence — medical documentation, witness testimony, expert opinions
Counter the insurance company’s threshold arguments
Present your case in a way that resonates with a judge or jury

I’ve handled hundreds of these cases. The difference between winning and losing often comes down to how well the case is prepared from day one.

The Bottom Line

Yes, you can sue the at-fault driver after a Michigan car accident — but only if your injuries meet the serious impairment threshold under MCL 500.3135. This isn’t something you should try to figure out on your own. The legal standard is nuanced, the insurance companies are aggressive, and the stakes are too high.
