Michigan drivers have one more reason to try and go green—the Michigan Supreme court has ruled that the price of car insurance premiums can now be based on a person’s credit score, and the worse the score, the higher the premium. This is unfortunate for many people who may have made a bad decision in the past and are now reaping unimagined consequences.

Adding to the burden is the fact that the state of Michigan has been notably hard-hit by the recent economic downturn, and many people are out of work. This means less money to pay off debts, and therefore a poorer credit score. Interestingly enough, recent studies have been conducted about the correlation between a person’s driving record and their credit score, and none can be found.

In Washington and Oregon, legislations has passed that prohibits the tying of an individual’s credit score to their insurance premiums. Unfortunately, this is the opposite of what has recently happened in Michigan.

It is unclear where the fight to remove the tying of credit scores to insurance premiums will now progress to in Michigan, but a spokesperson for the state Office of Finance and Insurance says that it will go on.
