What the 2019 Reform Changed
Before July 2020, Michigan had the most expensive auto insurance in the nation — and it wasn't close. The state's unlimited lifetime PIP benefits meant that catastrophic accident victims could receive millions of dollars in medical care over their lifetime, and those costs were spread across all policyholders.
The 2019 reform (Public Act 21 of 2019) introduced tiered PIP options for the first time, allowing drivers and fleet operators to choose their level of medical coverage. The tiers range from unlimited (the old default) down to $50,000 in PIP medical coverage, with corresponding premium reductions.
For commercial fleet operators, this reform was significant. A company with 20 vehicles could see meaningful savings by selecting a lower PIP tier — but the decision involves real trade-offs that need to be understood.
The PIP Tier Options for Commercial Auto
Michigan now offers five PIP medical coverage tiers: unlimited lifetime coverage (the pre-reform default), $500,000 in coverage, $250,000 in coverage, $100,000 in coverage (only if the policyholder has qualified health insurance), and $50,000 in coverage (only if the policyholder has Medicaid).
For commercial auto policies, the PIP tier applies to each covered vehicle. The choice affects what happens when your drivers or passengers are injured in an accident — regardless of fault. With unlimited PIP, all medical expenses are covered. With a $250,000 cap, expenses beyond that limit fall to the individual's health insurance or out of pocket.
Most commercial insurers recommend that fleet operators carefully evaluate their employees' health insurance coverage before selecting a lower PIP tier. If your employees have robust health insurance through your company, a $250,000 or $500,000 PIP tier may be appropriate. If many employees are on high-deductible plans or lack coverage, the unlimited tier provides better protection.
Michigan's High Bodily Injury Minimums
Beyond PIP, Michigan requires relatively high bodily injury liability minimums of 50/100 — $50,000 per person and $100,000 per accident. This is double the 25/50 minimum required in many states. Property damage minimum is $10,000, which is on the lower end.
The high BI minimums reflect Michigan's recognition that auto accidents in the Detroit metro area — with its heavy truck traffic, industrial corridors, and urban congestion — tend to produce larger claims. For commercial vehicles, which are involved in more severe accidents on average, these minimums should be treated as absolute floors, not targets.
Most Michigan commercial auto policies carry limits of at least $1 million combined single limit, often backed by a commercial umbrella policy. The cost difference between minimum limits and adequate limits is modest compared to the exposure.
Workers' Comp in Michigan: Moderate Costs
Michigan's workers' compensation rates rank 36th out of 51 jurisdictions at $0.90 per $100 of payroll — 17% below the national median. Coverage is required for all employers with one or more employees, with an exception for agricultural employers with fewer than three employees.
Michigan's workers' comp system has a unique feature: the state allows employers to choose between private insurance carriers and the Michigan Accident Fund (a competitive state fund). This gives employers an additional option when shopping for coverage, and the competitive pressure helps keep rates moderate.
The state's manufacturing heritage means that many Michigan employers are in higher-risk classification codes. If your business involves manufacturing, warehousing, or construction, your actual rates will be significantly higher than the state average. Accurate classification and a strong safety program are essential.
Optimizing Your Michigan Coverage Package
Michigan's unique insurance environment — reformed no-fault auto, moderate workers' comp, and high BI minimums — means that a cookie-cutter approach to commercial insurance won't work. The key decisions are interconnected: your PIP tier choice affects your commercial auto premium, which affects your total insurance budget, which may influence how much you invest in safety programs that lower your workers' comp costs.
Fleet telematics are particularly valuable in Michigan, where winter driving conditions (November through March) significantly increase accident frequency. Carriers that offer telematics discounts can reduce commercial auto premiums by 10-15% for fleets with good driving scores.
