Car Accident Laws in Michigan: Fault, Insurance & Deadlines

Michigan is a no-fault auto insurance state. After a crash, your own insurer pays your medical bills through Personal Injury Protection (PIP) benefits, regardless of who caused the wreck — you generally cannot sue the other driver for pain and suffering unless your injury meets a specific legal threshold. Separately, if you want to sue anyone (the at-fault driver or their insurer) for injury or property damage, Michigan's general deadline is 3 years from the date of the crash under MCL 600.5805 — but if you're only filing a claim for no-fault PIP benefits, that deadline is much shorter (generally 1 year), and if a government-owned vehicle was involved, you may have as little as 6 months to give formal notice. Confirm current deadlines with the Michigan Department of Insurance and Financial Services (DIFS) or a Michigan attorney before you assume you have time.

Is Michigan a no-fault or at-fault state?

Michigan is one of a small number of true no-fault states. Under the Michigan No-Fault Act, every auto policy issued in the state must include Personal Injury Protection (PIP) coverage. When you're hurt in a crash, you file with your own insurance company for PIP benefits, which are designed to pay your reasonable and necessary medical expenses, a portion of lost wages, and replacement services (help with tasks you can't do while recovering) — no matter who caused the accident.

The trade-off is that your right to sue the at-fault driver for pain and suffering (non-economic damages) is restricted. You can only step outside the no-fault system and sue in tort if you suffered death, permanent serious disfigurement, or a "serious impairment of body function," as defined under MCL 500.3135. Vehicle damage works differently: Michigan's Property Protection Insurance (PPI) pays for damage your vehicle causes to other people's property (not your own vehicle), and a separate "mini-tort" rule lets you pursue the at-fault driver directly for limited vehicle-damage costs. Because these rules are genuinely more complex than most states' systems, confirm how they apply to your specific injuries and damages with DIFS or a Michigan attorney.

Minimum auto insurance required in Michigan

Michigan's insurance requirements changed substantially under a 2019 reform (effective for policies issued or renewed on or after July 1, 2020). As of this writing, verify current figures with DIFS, since coverage options and dollar amounts can be adjusted by future legislation.

• Bodily injury liability: The standard minimum is $250,000 per person / $500,000 per accident. Drivers may sign a form to select lower limits, down to $50,000 per person / $100,000 per accident.
• Property Protection Insurance (PPI): Generally up to $1 million for damage your vehicle causes to property in Michigan; a lower minimum ($10,000) applies for damage caused outside Michigan.
• Personal Injury Protection (PIP) medical coverage: Since the 2020 reform, PIP is no longer one-size-fits-all. Drivers choose a medical coverage tier — commonly $50,000, $250,000, $500,000, or unlimited lifetime coverage — and some drivers who qualify (for example, those with certain other health coverage) may be allowed to opt out of PIP medical coverage entirely. This is a significant, Michigan-specific choice that affects how much of your own medical care is covered after a crash — review your options with DIFS or your insurer before assuming any particular limit applies to you.
• Uninsured/underinsured motorist (UM/UIM) coverage: Not required by Michigan law. It's sold as an optional add-on. Given that PIP does not compensate you for pain and suffering from an uninsured driver, and that Michigan does not mandate UM/UIM the way many states do, ask your insurer directly whether it's included, offered, or something you must add.

Because Michigan's system is unusually layered — tiered PIP, mini-tort, PPI, and a serious-impairment threshold all interacting — treat any coverage limit you read as a starting point and confirm your actual policy selections with your insurer or DIFS.

Statute of limitations: your deadline to file in Michigan

• Injury and property damage lawsuits (general rule): 3 years from the date of the injury or property damage, under MCL 600.5805. This is the deadline to file a lawsuit in court — it is not satisfied merely by reporting a claim to an insurance company.
• No-fault PIP benefit claims: A separate, shorter and stricter rule applies under MCL 500.3145. Michigan generally requires a written claim within one year of the accident and enforces a "one-year-back" limit on how far in the past you can recover unpaid benefits. Because this statute has been amended and interpreted in ways that can trap the unwary, do not wait — notify your insurer and pursue any PIP claim promptly, and confirm the exact current deadline with DIFS or an attorney.
• Minors: Special tolling rules can extend deadlines for injured children (generally measured from the child's 18th birthday) under MCL 600.5851 — verify how this applies to a specific case.
• Claims against a government-owned vehicle or entity: Much shorter. Under MCL 600.6431 and related governmental-immunity provisions, you may be required to file a written and notarized notice of intent to sue with the Court of Claims within roughly 6 months of the crash — far less than the standard 3 years. If a city, county, state, or other government vehicle or road was involved, treat this as urgent and get it confirmed immediately.

Shared fault in a Michigan crash

Michigan uses a form of modified comparative fault that splits differently depending on the type of damages:

• Economic damages (medical bills, lost wages, and similar out-of-pocket losses) are reduced by your percentage of fault, but are not cut off entirely — under MCL 600.2959, even a plaintiff found mostly at fault can recover a reduced share of economic losses.
• Non-economic damages (pain and suffering) are barred completely if you are found more than 50% at fault, under MCL 500.3135(2) and MCL 600.2959 — commonly called the "51% rule."

In practice, this means the percentage of fault assigned to you can eliminate your pain-and-suffering recovery while still allowing a reduced economic recovery. Confirm how an insurer or court is applying fault percentages to your specific claim.

When you must report a crash in Michigan

Under MCL 257.622, a driver involved in a crash that causes injury, death, or property damage that appears to total $1,000 or more must report the crash immediately to the nearest or most convenient police department or officer. The law does not define a specific number of hours or days — it requires immediate reporting — so don't wait if anyone was hurt or the damage looks like it could be at or above that threshold. Ask the responding officer how to obtain your official crash report, since you'll need it for insurance and any legal claim.

Damage caps and government-vehicle claims

• Mini-tort vehicle-damage cap: Michigan's no-fault system generally bars suing another driver for damage to your own vehicle — Property Protection Insurance and your own collision coverage handle that instead. As a narrow exception, the "mini-tort" provision under MCL 500.3135(3)(e) lets you recover a limited amount (currently capped at $3,000, raised from $1,000 under the 2019 no-fault reform effective in 2020) directly from an at-fault, insured driver, often used to cover a collision deductible. This cap can change by amendment — confirm the current figure with DIFS before relying on it.
• Serious-impairment threshold: Effectively acts as a gatekeeper on pain-and-suffering claims — if your injuries don't meet the legal definition under MCL 500.3135, you may be limited to PIP benefits regardless of how the crash happened.
• Government vehicle or road involved: As noted above, the notice deadline can shrink to roughly 6 months instead of 3 years, and governmental immunity can limit or bar claims outside specific statutory exceptions (like the motor-vehicle or highway-defect exceptions). Treat any crash involving a police car, municipal vehicle, school bus, or state/county road defect as time-sensitive from day one.

What to do after a crash in Michigan

1. Call 911 if anyone is injured, and move to safety if the vehicle is drivable and it's safe to do so.
2. Report the crash to police immediately if there's an injury, death, or apparent damage of $1,000 or more, as required by MCL 257.622.
3. Exchange information — names, contact info, insurance details, and license plate numbers — with all drivers involved.
4. Document the scene with photos of vehicle damage, license plates, road conditions, and any visible injuries.
5. Get medical care promptly, even if injuries seem minor — this both protects your health and creates a medical record tied to the crash date.
6. Notify your own auto insurer right away to open your PIP claim, since Michigan's PIP deadlines are shorter and stricter than the general 3-year injury deadline.
7. Request the official police crash report once available, and keep copies of everything — medical bills, repair estimates, wage-loss records, and correspondence with insurers.
8. Note if a government vehicle or road defect was involved and act immediately — the notice window can be as short as roughly 6 months.
9. Track your deadlines: mark the 3-year date for any lawsuit and the shorter PIP and government-notice deadlines separately, and confirm all of them with DIFS or a Michigan attorney given how fact-specific this area of law is.
