How does Michigan's no-fault car insurance work after the 2019 reform?

Michigan's no-fault auto system was overhauled by PA 21 of 2019 (effective July 2020). Before the reform, Michigan required unlimited PIP — your own insurer paid all medical costs for auto accident injuries for life, regardless of fault. The reform created a tiered choice: unlimited PIP (the old level), $500,000, $250,000, or (for Medicaid recipients) $50,000 per person per accident in lifetime medical benefits. Medicare recipients and those with qualifying health coverage have additional opt-out options. Your PIP pays: your medical expenses from accident injuries; 85% of your gross income (up to a monthly max — over $6,000/month in 2024) for wage loss; up to $20/day for replacement services (household tasks you cannot perform). Your PIP pays regardless of who caused the accident — you file with your own insurer, not the at-fault driver's insurer, for medical and wage loss. To sue the at-fault driver for pain and suffering, you must cross the serious impairment threshold (MCL 500.3135). Choosing your PIP level at policy purchase is a critical decision — lower PIP premiums come with significantly lower lifetime medical coverage; for catastrophic injuries, the difference between unlimited and $50,000 PIP is the difference between lifetime care and financial ruin.

What is the 'serious impairment' threshold in Michigan and how do I know if my injury qualifies?

MCL 500.3135 prohibits most tort lawsuits against at-fault drivers for pain and suffering unless the plaintiff can prove 'serious impairment of a body function.' Under Michigan Supreme Court's McCormick v. Carrier (2010), the standard focuses on whether the injury affects the plaintiff's general ability to conduct their life — not merely whether there's a medical diagnosis or a technically impaired body part. The analysis is: (1) Was there an objectively manifested impairment of a body function (demonstrable through medical evidence, not just subjective complaints)? (2) Was an important body function impaired? (3) Did the impairment affect the plaintiff's ability to lead a normal life — looking at what the plaintiff could do before versus after the injury in terms of work, daily activities, hobbies, family life, and recreation? Injuries that typically meet the threshold: permanent disability or limitation; significant spinal cord or back injuries with documented functional limitations; severe brain injury; significant burns or scarring; fractures with long recovery affecting daily life. Injuries that often don't meet the threshold: soft tissue injuries with complete recovery within weeks; minor fractures healing without limitation; temporary pain without lasting functional impact. An experienced Michigan auto accident attorney can evaluate whether your specific injuries and their documented functional impact are sufficient for threshold.

The driver who hit me has different insurance than me. How does Michigan no-fault work for my claim?

In Michigan's no-fault system, the general rule is that your own PIP insurer pays your medical costs and wage loss — regardless of who was at fault. You typically do NOT claim against the at-fault driver's insurer for medical or wage loss benefits. The priority order for who pays PIP if multiple policies could apply: (1) Your own auto policy; (2) A resident relative's auto policy (if no policy on your vehicle); (3) The policy on the vehicle you were in; (4) The Michigan Assigned Claims Plan (if no other applicable insurance). For tort claims (pain and suffering, economic damages beyond PIP): if you qualify under the serious impairment threshold, you can sue the at-fault driver — their liability insurance covers these tort damages. The at-fault driver's liability insurance does NOT provide your PIP benefits — those come from your policy. If the at-fault driver was uninsured, you can make an uninsured motorist claim against your own policy (if you have UM coverage) for tort damages. Michigan does not require UM coverage — it must be purchased separately. Given the complexity of Michigan's no-fault priority rules, retain a Michigan auto accident attorney quickly — priority disputes can significantly affect who pays and when.

What is Michigan's mini-tort and can I use it for my accident?

Michigan's mini-tort provision (MCL 500.3135(3)) allows you to sue the at-fault driver for up to $3,000 for property damage to your vehicle not otherwise compensated — specifically for the collision deductible or unrepaired vehicle damage. If the at-fault driver was more than 50% at fault and your vehicle has damage exceeding what your collision coverage pays (your deductible, or if you have no collision coverage, the entire vehicle damage up to $3,000), you can file a mini-tort claim against the at-fault driver directly. Mini-tort is a simplified, small claims-level property damage claim — not a pathway to pain and suffering. The $3,000 cap severely limits its usefulness for significant property damage. Mini-tort claims are often handled in small claims court or through the at-fault driver's liability insurer directly. If your vehicle damage is $3,500 and you have no collision coverage, the mini-tort gives you a legal right to $3,000 from the at-fault driver. If you have collision coverage, you get your vehicle repaired through your collision coverage and pursue your deductible through mini-tort. Mini-tort has nothing to do with medical benefits or pain and suffering — it is purely a vehicle damage mechanism.

What is the Michigan Assigned Claims Plan and when does it apply?

The Michigan Assigned Claims Plan (MACP) is the no-fault system's safety net for accident victims who have no applicable insurance. The MACP pays limited PIP benefits when: (1) the accident victim has no auto insurance; (2) no household member has auto insurance; (3) the vehicle involved has no applicable insurance; and (4) the vehicle is owned by someone with no insurance. The MACP pays benefits at a reduced level — currently up to $250,000 in medical benefits and reduced wage loss — not unlimited benefits. The MACP assigns the uninsured claimant to a specific insurer from a pool of Michigan no-fault insurers, who then handles the claim. Important: if you are involved in an accident and have no PIP coverage, immediately contact the MACP (operated by the Michigan Automobile Insurance Placement Facility) to file for benefits. The MACP has strict notice deadlines — you must provide written notice within 1 year of the accident. Failing to timely notify the MACP can bar you from benefits entirely. The MACP is a last resort — the preferred approach is maintaining at least the minimum PIP coverage, which in Michigan now starts at $50,000 for Medicaid recipients.

Q: What is Michigan's fault rule for car accidents?

Michigan follows modified comparative negligence. You can recover only while your share of fault stays under the state bar (generally 50–51%); your award is cut by your fault percentage, and at or above the bar you recover nothing.

Quick Answers — verified January 2026

Is Michigan a no-fault state?

Yes — Michigan is a no-fault state. Your own Personal Injury Protection (PIP) pays your medical bills first, no matter who caused the crash. You can step outside no-fault and sue the other driver only if your injury meets Michigan's tort threshold.

What is the statute of limitations for a car accident in Michigan?

In most Michigan car-accident injury cases you generally have 3 years from the date of the crash to file a lawsuit (MCL § 600.5805). Treat this as the general deadline, not a guarantee: claims against a government agency, wrongful-death claims, property-damage-only claims, injured minors, and later-discovered injuries can follow different limits. Missing the deadline usually ends the claim, so confirm the current statute before you rely on it.

Michigan Car Accident Law — Key Facts

Michigan has the most complex no-fault auto insurance system in the country — reformed by PA 21 of 2019
Unlimited PIP (Personal Injury Protection) still available; tiered PIP options allow lower coverage levels
Serious impairment threshold: must prove "serious impairment of body function" to sue in tort (MCL 500.3135)
Modified comparative fault: 51% bar (MCL 600.2959)

Michigan's no-fault auto insurance system — overhauled by 2019's PA 21 — is the most complex in the United States. Michigan was the only state with unlimited lifetime medical benefits for accident injuries; the 2019 reform created a tiered PIP system with options ranging from $50,000 to unlimited, at varying premium levels. Despite the reform, Michigan's no-fault system remains far more extensive than other states' PIP systems. The tort threshold — requiring proof of "serious impairment of body function" to sue the at-fault driver in tort — filters most claims through the no-fault system rather than through litigation.

Michigan No-Fault PIP — Post-2019 Reform

PA 21 of 2019 (effective July 1, 2020) created a tiered PIP system for Michigan auto insurance:

Unlimited PIP: Available — still the maximum level; provides lifetime unlimited medical coverage for accident injuries
$500,000 PIP: Per-person per-accident lifetime limit
$250,000 PIP: Per-person per-accident lifetime limit
$50,000 PIP: Available for Medicaid recipients only
Medicare opt-out: Available for Medicare recipients; Medicare becomes primary payer
PIP opt-out: Available only for those with qualifying health insurance that covers auto accident injuries (must have $250K+ coverage)

PIP covers: medical expenses (coordinated with or primary over health insurance depending on election); wage loss (85% of gross income up to a statutory maximum, adjusted periodically — roughly $6,000+/month in 2024); replacement services (up to $20/day for household services the injured person cannot perform). Michigan's PIP coverage is first-party — your own insurer pays regardless of who was at fault.

Michigan's Tort Threshold — Serious Impairment of Body Function

To sue the at-fault driver in tort for pain and suffering damages beyond PIP, a Michigan plaintiff must prove "serious impairment of a body function" under MCL 500.3135. The Michigan Supreme Court in McCormick v. Carrier (2010) established the current standard: the impairment must affect the plaintiff's ability to lead a normal life — how the injury has affected the plaintiff's general ability to conduct their life, not just whether there is a measurable physical deficit. Factors courts consider: how the injury affected the plaintiff's lifestyle, hobbies, employment, relationships, and daily activities. Threshold analysis is heavily fact-specific. Injuries commonly meeting the threshold: permanent disability; significant back injuries affecting major life activities; severe scarring; brain injuries. Injuries commonly not meeting the threshold: soft tissue injuries with full recovery; minor fractures with complete resolution; temporary limitation.

Michigan Mini-Tort

Michigan's "mini-tort" provision (MCL 500.3135(3)) allows an at-fault driver to be sued for up to $3,000 in property damage not covered by the other driver's collision insurance (or the other driver's unrepaired vehicle damage). The mini-tort is a very limited property damage remedy — intended to cover the no-fault collision deductible. It is NOT a pathway to pain and suffering — it is purely for vehicle property damage exceeding $3,000 that the at-fault driver can be held responsible for.
