What makes Michigan different
The insurance side has no such ceiling, and Michigan is the state where that gap is widest. Premiums here are among the highest in the country, so the same conviction that costs a bounded amount at the courthouse can cost a multiple of it across the following three years. On this page, more than on most, the three-year figure is the number worth reading first.
What connects the two is the abstract — the record the Secretary of State keeps of convictions and points. A Michigan traffic case is in practice a negotiation about what appears on that abstract, which is why a reduction to a non-moving violation is the outcome so many Michigan drivers ask for by name.
