Michigan car insurance requirements and laws

Minimum car insurance requirements

Michigan's no-fault system was overhauled by the 2019 reform law, and the main changes took effect for policies issued or renewed after July 1, 2020. Every Michigan policy still includes three no-fault parts, but you now make two important choices: how much PIP medical coverage to buy and whether to accept the new default liability limits. See michigan's no-fault reform explained and compare states with the state car insurance requirements lookup.

The six PIP medical choices (per person, per accident), as listed by DIFS:

1. Unlimited — the default if you do not choose.
2. Up to $500,000.
3. Up to $250,000.
4. Up to $250,000 with exclusions — the named insured or household members can be excluded if they have non-Medicare health coverage that covers auto accident injuries.
5. Up to $50,000 — only if the named insured is enrolled in Medicaid and household members have other auto or health coverage for auto injuries.
6. Opt out of PIP medical — only if the named insured has Medicare Parts A and B and household members have other qualifying coverage.

Insurers must give you a form explaining the risks of each option. To use a health plan to justify a lower option, the plan generally must cover auto injuries and have an individual deductible below a limit DIFS publishes each year ($6,579 on its current page). The reform also required insurers to cut average PIP medical premiums for eight years. Why Michigan car insurance costs what it does covers the trade-offs.

What the minimums mean in practice. Suppose you choose the lowest 50/100 liability limits and cause a crash that seriously injures another driver, whose PIP covers medical bills only up to $250,000. If their care costs $400,000, they can sue you for the $150,000 their PIP does not pay, plus pain and suffering. Your $50,000 limit leaves the rest to you. That exposure is why the law made 250/500 the default.

Fault system and what it means after a crash

Michigan is a no-fault insurance state. Your own PIP pays medical bills (up to the limit you chose), plus lost wages and replacement services, whoever caused the crash. Damage your car does to other property in Michigan is paid by PPI, not liability coverage. Tort lawsuits are limited (MCL 500.3135):

• Pain and suffering: only for death, serious impairment of body function or permanent serious disfigurement, and not if you are more than 50% at fault.
• Excess medical costs: since the reform, you can sue an at-fault driver for medical expenses above your PIP limit or excluded by your choice.
• mini-tort: you can recover up to $3,000 (up from $1,000 for crashes after July 1, 2020) from an at-fault driver for vehicle damage your insurance does not cover, such as your deductible.

Michigan applies modified comparative negligence: if you are more at fault than the others combined, your economic damages are reduced and you receive no noneconomic damages (MCL 600.2959). Lawsuits must generally be filed within three years, but PIP claims require written notice or a lawsuit within one year of the accident (MCL 500.3145; statutes of limitations for car accident claims).

Optional coverage worth considering here

• Uninsured/underinsured motorist coverage. It is optional, but the Insurance Research Council estimates 22.3% of Michigan drivers were uninsured in 2023, the fourth-highest rate in the country. With pain-and-suffering suits now more common after the reform, UM/UIM fills an important gap (uninsured and underinsured motorist coverage explained).
• Collision. Because no-fault limits suits over vehicle damage to the $3,000 mini-tort, collision is how most drivers repair their own car. Insurers offer standard, broad form and limited options.
• Comprehensive for theft and deer strikes.

What drives rates in Michigan

The NAIC puts Michigan's average annual expenditure at $1,444 in 2023, above the national average of $1,282, but down from $1,499 in 2019, before the reform took effect (What NAIC auto insurance data measures).

Historically, unlimited lifetime PIP medical benefits and the assessment to fund the Michigan Catastrophic Claims Association made Michigan coverage among the most expensive in the country. The reform's PIP choices, fee schedules for medical providers and required premium reductions brought average costs down. Detroit still pays much more than the rest of the state because of claim frequency, theft and litigation (Why your ZIP code changes your car insurance price). The reform also restricted insurers' use of non-driving factors such as sex and marital status.

Penalties for driving uninsured

Driving without required no-fault security, or knowingly letting someone drive your uninsured car, is a misdemeanor punishable by a fine of $200 to $500, up to one year in jail, or both (MCL 500.3102). An uninsured owner injured while driving their own car generally cannot collect PIP benefits, and the law bars them from recovering pain-and-suffering damages (MCL 500.3135). See penalties for driving without insurance and no pay, no play laws.

SR-22 and high-risk drivers

Michigan drivers rarely need an SR-22 filing; license reinstatement after serious violations runs through the Secretary of State. Drivers who cannot get coverage in the voluntary market can apply through the Michigan Automobile Insurance Placement Facility, the state's assigned risk plan. See SR-22 insurance explained and high-risk car insurance: options when insurers say no.

Insurers with a strong presence in Michigan

Michigan has one of the strongest home-state markets. Lansing-based Auto-Owners Insurance, AAA (AAA Michigan, based in Dearborn), Farm Bureau Insurance of Michigan, Frankenmuth Insurance and The Hanover (whose Citizens Insurance unit is based in Howell) compete with national writers State Farm, Progressive and Allstate. See regional car insurers: when smaller carriers can beat the giants.
