Michigan’s auto insurance reform law has contributed to an 18 percent drop in average premium costs from 2019-20, the steepest decline in the country over that time period, according to a new analysis by Poverty Solutions at the University of Michigan.
However, Michigan still has the most expensive auto insurance in the United States, and a 2019 law has failed to reduce disparities in cost by race and geography.
A new policy brief, “Building on Michigan’s auto insurance reform law,” offers recommendations to further reduce premiums and address the unintended consequences of reform that led to some catastrophic accident victims losing access to medical care.
“The 2019 reform law was a first step, but lawmakers should not be content. More must be done to eliminate discriminatory rate-setting practices and further reduce premiums,” said Amanda Nothaft, senior data and evaluation manager at Poverty Solutions and co-author of the policy brief with Patrick Cooney, Poverty Solutions assistant director of policy impact.
“We also need to consider the impact on people who have been catastrophically injured in auto accidents and ensure medical providers are appropriately reimbursed for long-term care.”
Cooney also co-authored a March 2019 policy brief that examined the cost of auto insurance in Michigan as an economic mobility issue that prevented people across the state — and especially in Detroit, where average premiums are more than double the statewide average — from moving out of poverty.
That research informed the bipartisan auto insurance reform law that passed in May 2019 and which started to take effect in July 2020. Implemented policy changes recommended by Poverty Solutions included eliminating mandatory unlimited personal injury protection coverage, restricting the use of non-driving factors like one’s ZIP code and credit score to set auto insurance rates, and enforcing fee limits for medical care related to injury accidents covered by auto insurance.
The new analysis — based on data from The Zebra, an auto insurance comparison marketplace that collects rate information — shows the reforms have already lowered costs. Key findings include:
The policy brief also includes recommendations on how to further lower rates and ensure Michigan’s auto insurance system does stand as a barrier to economic mobility. While unlimited personal injury protection coverage is no longer mandatory, Michigan is still an outlier in the amount of PIP that drivers have to purchase. Offering more PIP coverage options would help reduce rates overall.
To address persistent racial disparities in auto insurance rates, the researchers recommend more regulation of the factors used to set rates by establishing mandatory driving-related factors that must carry a certain weight in the calculation.
The 2019 reform prohibited the use of certain non-driving factors, but insurance companies can still use proxies for those factors — like “territories” instead of ZIP codes and insurance scores that include a credit score component — that reinforce insurance redlining.
Another recommendation is to revisit reimbursement rates for medical procedures not on the Medicare fee schedule.
Containing the medical costs for auto accident victims is key to reducing auto insurance costs, but the sharp reduction in reimbursement rates for certain services under the 2019 reform has forced some medical providers out of business and jeopardized access to long-term care for some catastrophic accident victims.
Lawmakers could restructure the Catastrophic Claims Fund to support long-term care facilities and cover higher reimbursement rates.
“Michigan’s Catastrophic Claims Fund could play a much larger role in ensuring long-term support for people catastrophically injured in an auto accident,” Cooney said. “The 2019 auto insurance reform made meaningful changes that lowered rates for Michigan drivers. But there is much more to do. We need to acknowledge what’s working and fix what’s not.”
“Michigan still has the most expensive auto insurance in the United States, and the 2019 law has failed to reduce disparities in cost”. I told you so.
