What Michigan requires by law
Michigan runs the most complicated auto insurance system in the country. Here is the plain version.
You need bodily injury liability with a statutory minimum of $50,000 per person and $100,000 per accident. The default on every policy is 250/500 unless you sign for less. You need personal injury protection, where you now choose a medical coverage level, from unlimited lifetime benefits down to capped options, with opt-outs for some drivers whose health insurance qualifies. You need $1 million of property protection insurance for damage your car does to Michigan buildings and parked vehicles. The $10,000 property damage liability line only matters when you crash outside Michigan.
Driving uninsured is a misdemeanor and worse than it sounds. Uninsured drivers cannot claim PIP benefits and, if 50 percent or more at fault, cannot recover pain-and-suffering damages at all.
Is the minimum enough? Selecting every floor saves real money and rebuilds the exact gaps the old system existed to prevent. Keep the 250/500 default if you can. Michigan juries see catastrophic crash injuries regularly. That is why the default is high.
What drives premiums in Michigan
- The no-fault legacy. Decades of unlimited lifetime medical benefits made Michigan the most expensive state in America. The 2019 reform (effective July 2020) cut costs meaningfully, but PIP claims and the catastrophic claims fund still set a high floor.
- Uninsured drivers. The Insurance Research Council put 22.3 percent of Michigan drivers as uninsured in 2023, fourth highest nationally, a hangover from years of unaffordable premiums.
- Detroit-area frequency and theft. Metro Detroit’s crash and theft rates remain elevated, though the rating-factor reforms spread costs more fairly than the old ZIP-code pricing did.
- Collision-heavy structure. Because your own policy pays for your car’s damage in-state, collision coverage does more work in Michigan and costs accordingly.
How to pay less in Michigan
- Reshop since the reform, and again now. Carriers repriced Michigan unevenly after 2020, and the spread between quotes is still unusually wide. Start with our cheapest auto insurance guide.
- Choose your PIP level deliberately. If you have qualifying health coverage, a lower PIP level or opt-out is the single biggest lever on a Michigan premium. Read the exclusions before you sign.
- Do not skim the liability default away. Cutting 250/500 to 50/100 saves little and exposes much.
- Raise your collision deductible. Collision is a big share of a Michigan premium, so deductible moves pay more here.
- Check that the banned factors stayed banned. Quotes should not ask about your credit or marital status for rating. If something smells off, the DIFS consumer line exists. More moves in how to lower your premium.
