What Michigan's Auto Insurance Reform Means for Drivers
The 2018 Michigan auto insurance reform was designed to increase consumer protection, improve transparency, and reduce unfair premium practices. The law requires insurers to disclose how they calculate rates, limits the use of certain data, and mandates a state‑run insurance pool for high‑risk drivers. For most drivers, the biggest impact comes from the use of credit‑based insurance scores (CBIS).

Credit Scores in Michigan Insurance: The Basics
What is a Credit‑Based Insurance Score?
A CBIS is a numeric value derived from a driver's credit history. Insurance companies use it to predict the likelihood of filing a claim. Higher scores generally correlate with lower risk and lower premiums.
How Michigan Law Regulates CBIS Use
Michigan law limits the weight insurers can assign to CBIS in rate calculations. The state's Insurance Division requires that credit information be a "minor factor" and not the primary determinant of rates. Insurers must also provide a written statement explaining how the score influenced the premium.
Jim Stamas: Industry Voice on Reform and Credit Scores
Jim Stamas, a former Michigan Insurance Commissioner and current insurance analyst, has been vocal about the reform's effectiveness. Stamas argues that while the law improved transparency, many insurers still rely heavily on credit scores, especially for drivers with limited driving history. He recommends that consumers regularly review their credit reports and seek rate comparisons to ensure they are not being overcharged.
Practical Tips for Michigan Drivers
- Check Your Credit Score. Obtain a free score from major bureaus and monitor changes.
- Request a Rate Explanation. Insurers must explain how your CBIS affected your premium.
- Shop Around. Compare quotes from multiple carriers; some may weigh CBIS less.
- Consider Credit‑Free Riders. Certain insurers offer policies that ignore credit history.
