Why rates in Michigan look the way they do
Michigan dropped from the most expensive auto state to roughly average in three years — NAIC 2023 reports $2,014/yr, down from $2,800+ before reform. Most savings came from drivers choosing the $250K or $500K PIP tier instead of unlimited.
Michigan rewrote its auto-insurance law in 2019 (PA 21-22), ending the country’s only unlimited-PIP requirement and letting drivers pick coverage tiers from $50K to unlimited. Premiums fell significantly in 2020-2022 but have begun climbing again.
A few state-specific dynamics worth knowing:
- PA 21-22 (effective July 2020) ended unlimited PIP; drivers now choose $50K/$250K/$500K/unlimited tiers.
- Michigan Catastrophic Claims Association (MCCA) handles claims over the chosen PIP threshold.
- Detroit ZIP codes still pay materially more than statewide average due to historical loss patterns.

Michigan auto insurance — what affects your rate

The four factors that drive your specific rate the most: ZIP code (theft + claim density), age (under 25 and over 70 pay materially more), vehicle (repair-cost class and theft rate), and driving record (one at-fault accident or moving violation typically lifts a rate 20-40%).
Minimum auto insurance required in Michigan
$50,000 BI per person / $100,000 per accident / $10,000 PD plus PIP coverage. PIP tier is selected by the driver post-2020 reform ($50K to unlimited).
