LANSING, Mich. (AP) — Michigan drivers with auto insurance will soon starting getting previously announced $400 refunds per vehicle.

Gov. Gretchen Whitmer and the state's top insurance regulator said Monday that a $3 billion transfer of surplus funds from the Michigan Catastrophic Claims Association to car insurers will be completed this week.

The companies will have 60 days to issue the refunds — no later than May 9.

The governor has attributed the surplus and refunds in part to 2019 law that curbed or cut what health providers and attendant care aides can charge auto insurers.

Critics say the slashed reimbursements have led to injured motorists losing quality care.
