Michigan windshield insurance law under the no-fault system

Michigan's mandatory no-fault auto insurance does not cover windshield or glass damage to your own vehicle. Comprehensive coverage — entirely optional under Michigan law — is the sole practical mechanism for most glass claims, making Michigan an outlier among states with robust no-fault systems. The state has no zero-deductible glass mandate, no OEM glass requirement, and no ADAS recalibration statute, though it does maintain an explicit anti-steering law (MCL 500.2110b) that specifically names auto glass. PA 21 of 2019, Michigan's landmark no-fault reform, left glass coverage entirely untouched — its PIP tiers, medical fee schedules, and MCCA restructuring all apply exclusively to bodily injury claims. This report details exactly how Michigan's system creates a unique coverage landscape for glass claims, where the law is clear, and where it is silent.

Michigan's no-fault framework creates a glass coverage gap unlike any other state

Michigan's Insurance Code (MCL 500.3101 et seq.) mandates three coverages: Personal Injury Protection (PIP, MCL 500.3107), Property Protection Insurance (PPI, MCL 500.3121), and Residual Liability Insurance (MCL 500.3131). None of these mandatory coverages pay for windshield or glass damage to the insured's own vehicle under normal driving conditions. This structural gap distinguishes Michigan from every other state's insurance framework.

PIP is exclusively a bodily injury coverage. MCL 500.3105 limits liability to "accidental bodily injury arising out of the ownership, operation, maintenance, or use of a motor vehicle." MCL 500.3107 defines the three benefit categories — allowable medical expenses, work loss, and replacement services — all tied to an injured person's care and recovery. PIP has zero application to property damage of any kind, including glass. This is one of the most common misconceptions among Michigan drivers.

PPI sounds like it should cover property damage, but critical exclusions eliminate most glass scenarios. MCL 500.3121(1) establishes PPI as covering "accidental damage to tangible property arising out of the ownership, operation, maintenance, or use of a motor vehicle." However, MCL 500.3123 imposes two dispositive exclusions. First, MCL 500.3123(1)(a) excludes "vehicles and their contents, including trailers, operated or designed for operation upon a public highway" — meaning any vehicle being driven is excluded. Second, MCL 500.3123(1)(b) excludes property owned by the named insured, their spouse, or domiciled relatives when they were the owner, registrant, or operator. PPI is fundamentally a third-party property coverage: it pays when your vehicle damages someone else's fence, building, or properly parked car. It does not cover damage to your own vehicle.

The mini-tort provision (MCL 500.3135(3)(e)) offers limited, narrow relief. Michigan's no-fault system abolishes tort liability for vehicle-to-vehicle property damage, replacing it with a mini-tort allowing recovery of up to $3,000 (increased from $1,000 by PA 21 of 2019, effective July 1, 2020) from an at-fault driver. Mini-tort applies only when another driver is more than 50% at fault and only for damage not covered by the claimant's own insurance. For the most common windshield damage scenario — road debris striking the windshield while driving — mini-tort is inapplicable because there is typically no identifiable at-fault driver.

Comprehensive coverage is the primary glass mechanism, and it is entirely optional. MCL 500.3101 makes no mention of comprehensive coverage among required coverages. DIFS official publications (FIS-PUB 0202A) explicitly classify both comprehensive and collision as optional. A Michigan driver carrying only the mandatory minimum insurance (PIP + PPI + BI/PD liability) has zero coverage for windshield damage under virtually all circumstances.

This differs fundamentally from states like Florida, where F.S. 627.7288 mandates zero-deductible windshield replacement under comprehensive, and from traditional at-fault states like Ohio or Illinois, where a driver can sue another negligent driver's liability insurer for the full cost of glass damage. Michigan's abolition of tort liability for vehicle property damage (MCL 500.3135(3)) forecloses that option, leaving consumers more dependent on their own optional coverage than drivers in any other system.

How glass damage actually gets paid — coverage by scenario

The coverage that pays for glass damage in Michigan depends entirely on the circumstances. Understanding these distinctions is essential because Michigan law draws sharp lines between coverage types that do not exist in most other states.

For non-collision glass damage (road debris, hail, vandalism, falling objects, temperature stress) — which represents the vast majority of windshield claims — only comprehensive coverage applies. This coverage is optional, subject to the policyholder's chosen deductible (typically $100–$1,000), and governed by the individual insurance contract rather than any Michigan-specific glass statute. Many insurers voluntarily waive the deductible for minor chip repairs (typically cracks under six inches) because repairs cost less than replacements.

For collision-related glass damage (windshield broken during a crash), collision coverage applies under MCL 500.3037. Michigan offers three collision variants — limited, standard, and broad form. Under broad form collision, the deductible is waived when the insured was not substantially at fault (50% or less). Under limited collision, no benefits are paid if the insured was more than 50% at fault. Collision coverage is also entirely optional.

The one scenario where Michigan's mandatory no-fault system does cover glass involves properly parked vehicles. Under the parked-car exception in MCL 500.3123(1)(a), if a properly parked vehicle's windshield is damaged by another moving vehicle, the at-fault vehicle's PPI pays for the damage — without regard to fault (MCL 500.3121(2)), without a deductible for the claimant, and up to $1,000,000 per accident (MCL 500.3121(5)). The parked vehicle owner does not need comprehensive coverage to receive this benefit. This mechanism is genuinely unique to Michigan and provides a narrow but real advantage over other states, where a parked-car glass claim would typically require either the victim's own comprehensive coverage (with deductible) or proof of fault against the other driver's liability insurer.

| Scenario | Coverage that pays | Key MCL reference | Deductible | |---|---|---|---| | Road debris cracks windshield while driving | Comprehensive (optional) | No glass-specific MCL | Policy deductible applies | | Hail, vandalism, or falling object damages glass | Comprehensive (optional) | No glass-specific MCL | Policy deductible applies | | Windshield broken in a collision | Collision (optional) | MCL 500.3037 | Depends on collision type | | Properly parked car's glass hit by another vehicle | Other driver's PPI (mandatory) | MCL 500.3121; 500.3123(1)(a) exception | None for claimant | | At-fault driver causes glass damage in collision | Mini-tort recovery up to $3,000 | MCL 500.3135(3)(e) | N/A — tort recovery | | No comprehensive or collision carried | Out of pocket | N/A | Full cost borne by driver |

PA 21 of 2019 left glass coverage entirely untouched

Michigan's 2019 no-fault reform (PA 21 of 2019, signed May 30, 2019) was the most significant restructuring of the state's auto insurance system in four decades. It contains no provisions that directly address windshield repair, glass replacement, or auto glass coverage of any kind. The reform focused almost exclusively on PIP medical benefits, medical provider reimbursement, and catastrophic claims — all of which pertain to bodily injury, not vehicle property damage.

PIP coverage tiers do not affect glass claims. MCL 500.3107c, added by PA 21, created four PIP options: $50,000 (Medicaid enrollees only), $250,000, $500,000, and unlimited. These tiers govern only allowable medical expenses for bodily injury. A driver who selects reduced PIP coverage saves on the PIP portion of their premium but experiences no change whatsoever to their glass coverage, which remains governed by their optional comprehensive policy.

The medical fee schedule does not apply to glass. MCL 500.3157, as amended by PA 21, caps reimbursement for medical treatment of bodily injury at 190% of Medicare rates (after July 1, 2023) for most providers. This fee schedule applies exclusively to "treatment or rehabilitative occupational training" rendered by "a physician, hospital, clinic, or other person" for "accidental bodily injury covered by personal protection insurance." Auto glass repair shops are not medical providers, and glass damage is not bodily injury. The fee schedule has no application to glass claims. DIFS Bulletin 2021-38-INS confirmed that products and services not provided by medical professionals are not subject to MCL 500.3157 caps.

Two indirect effects merit mention. First, the mini-tort cap increase from $1,000 to $3,000 (MCL 500.3135(3)(e), effective July 1, 2020) marginally expanded recovery options for uninsured vehicle damage in fault-based collisions, including glass. Second, MCL 500.2111, as amended, prohibited certain non-driving rating factors (sex, marital status, credit score, education, occupation, postal zone) for all auto coverages including comprehensive, effective July 1, 2020. This could indirectly affect comprehensive premiums but does not change the nature of glass coverage itself.

The Milliman Report (December 2025), commissioned by DIFS to study PA 21's impacts, specifically confirmed: "The cost of providing Physical Damage coverage was not materially impacted by the reform." Physical damage coverage encompasses both collision and comprehensive — the coverages that actually handle glass claims.

The MCCA has zero involvement with glass claims

The Michigan Catastrophic Claims Association (MCL 500.3104) is a mandatory reinsurance mechanism created in 1978 to indemnify member insurers for catastrophic PIP claims exceeding a specified retention threshold. The current threshold is approximately $635,000 (adjusted biennially under MCL 500.3104(2)(o) by the lesser of 6% or CPI).

The MCCA covers only "ultimate loss sustained under personal protection insurance coverages" (MCL 500.3104(2)). This language is dispositive: the MCCA reimburses insurers exclusively for PIP (bodily injury) claims. It has no jurisdiction over comprehensive claims, collision claims, PPI claims, or property damage claims of any type. A glass damage claim cannot reach the MCCA for two independent reasons: it is categorically the wrong type of coverage, and a typical windshield replacement ($100–$500) is astronomically far from the $635,000 threshold designed for catastrophic injuries like spinal cord trauma and traumatic brain injuries.

PA 21 of 2019 significantly restructured the MCCA. Post-reform, MCCA indemnification is limited to policies with unlimited PIP (MCL 500.3107c(1)(d)) for policies issued after July 1, 2020. Drivers who choose capped PIP tiers forgo MCCA catastrophic coverage. The MCCA per-vehicle assessment, which peaked at $220 pre-reform, dropped to $100 in 2020–2021, then shifted to a deficit recoupment model. None of these changes have any connection to glass claims. The MCCA assessment does marginally affect total auto insurance premiums — and thus the overall affordability of carrying comprehensive coverage — but this is an extremely indirect relationship.

MCL 500.2110b explicitly protects glass shop choice, but OEM glass is unregulated

Michigan possesses one notable consumer protection specifically relevant to glass claims. MCL 500.2110b (enacted 2004, Act 190), titled "Use of automobile repair or automobile glass repair or replacement service," contains three substantive provisions:

MCL 500.2110b(1) prohibits automobile insurers, their employees, agents, and adjusters from "unreasonably restrict[ing] an insured from using a particular person, place, shop, or entity for the providing of any automobile repair or automobile glass repair or replacement service or product covered by the policy."

MCL 500.2110b(2) requires insurers to disclose, prior to or at the time of claim filing, whether they have agreements with any repair or replacement facility, and to inform the insured "that he or she is under no obligation to use a particular repair or replacement facility."

MCL 500.2110b(3) mandated DIFS to develop a consumer education plan about repair rights, including the insured's ability to report violations through DIFS's toll-free number or website.

The anti-steering standard is "unreasonably restrict" — not an absolute prohibition. Insurers may recommend preferred vendors (such as Safelite) but cannot coerce, pressure, or materially penalize consumers for choosing independent shops. Critically, MCL 500.2110b(3) also notes that "the insurer is not required to pay more than a reasonable amount for repairs and parts," preserving the insurer's right to limit reimbursement to prevailing market rates even when the consumer chooses a higher-priced shop.

Michigan law is silent on OEM versus aftermarket glass. The Aftermarket Crash Parts Act (MCL 257.1361–1364) regulates non-OEM parts but defines "aftermarket crash part" as "a replacement part for a nonmechanical sheet metal part or plastic part that constitutes part of the exterior of a motor vehicle." Glass falls outside this definition. No Michigan statute requires insurers to provide OEM glass or grants consumers the right to demand it. The choice between OEM and aftermarket glass is governed entirely by the individual insurance contract and the insurer's claims policies. Federal Motor Vehicle Safety Standard 205 (FMVSS 205) governs the safety certification of all automotive glazing used nationwide, but this is a federal standard, not a Michigan requirement regarding insurance coverage.

ADAS recalibration exists in a complete statutory vacuum

Michigan law contains no statute, regulation, or DIFS guidance addressing how Advanced Driver Assistance Systems recalibration is classified or covered when performed as part of a windshield replacement. This is a significant regulatory gap given that an increasing percentage of vehicles on Michigan roads feature forward-facing cameras, lane-departure warning systems, and other ADAS components mounted to or near the windshield that require recalibration after glass replacement.

By inference from general insurance principles, ADAS recalibration performed following a covered windshield replacement is treated as a necessary and consequential component of the glass claim under comprehensive coverage. The need for recalibration arises directly from the covered loss. Most major insurers operating in Michigan will cover recalibration when the vehicle manufacturer documents it as required, though some require pre-authorization and apply it under the same deductible as the glass claim. Recalibration typically costs $200–$500 on top of the replacement itself.

The Auto Glass Safety Council's AGRSS Standard (ANSI/AGSC/AGRSS 005-2022) establishes voluntary industry standards for recalibration, requiring purpose-built equipment, qualified technicians, and return to OEM specifications. Michigan has not adopted this standard by statute or regulation, but it represents the recognized standard of care. Several other states have moved ahead of Michigan on ADAS legislation: Arizona enacted SB 1410 requiring glass shops to inform customers about calibration needs, New York has pending legislation (S.4879-B/A.6943-B) establishing ADAS calibration standards, and NCOIL approved a Motor Vehicle Glass Model Act in early 2025 that includes ADAS provisions. Michigan has taken no comparable action.

DIFS has issued no glass-specific guidance

A comprehensive review of DIFS bulletins from 2019 through early 2026 reveals no bulletin, advisory opinion, or regulatory guidance specific to glass claims, glass repair standards, or windshield replacement practices. The only DIFS bulletin with tangential relevance is Bulletin 2025-25-INS (Improper Claims Administration Practices in Automobile Insurance, issued October 24, 2025, superseding Bulletin 2025-19-INS), which broadly addresses improper practices for "automobile collision and comprehensive coverages." This bulletin identifies violations including misrepresentations during claims administration, failure to make timely payments, and failure to investigate claims promptly — all of which could apply to glass claims where insurers engage in steering or claim suppression, but the bulletin does not mention glass specifically.

DIFS's consumer complaint process (michigan.gov/DIFScomplaints, 877-999-6442) remains available for consumers who believe their rights under MCL 500.2110b have been violated, but no publicly available DIFS data disaggregates glass-specific complaints. The general unfair trade practices provisions of MCL 500.2006 and MCL 500.2026 provide additional enforcement authority against insurers who mishandle glass claims.

What Michigan consumers actually face compared to other states

Michigan's system creates a distinctly challenging landscape for consumers dealing with windshield damage. The practical reality operates on three tiers of disadvantage.

First, PLPD-only drivers have zero glass coverage. A Michigan driver carrying only the mandatory minimums — which is legal and not uncommon, particularly in economically disadvantaged areas like Detroit — has absolutely no insurance mechanism to cover windshield damage. The only exception is the narrow PPI parked-car scenario. In a traditional at-fault state, this same driver could at least pursue the negligent party's liability insurer for glass damage caused by another driver. In Michigan, MCL 500.3135(3) abolishes that tort right, leaving only the $3,000 mini-tort for collision scenarios.

Second, high-deductible comprehensive policyholders are functionally uninsured for glass. A driver with a $500 or $1,000 comprehensive deductible facing a $300–$500 windshield replacement gains nothing from filing a claim. This is true nationally, but Michigan provides no statutory remedy — unlike Florida (F.S. 627.7288), Kentucky (KRS 304.20-060), and South Carolina (SC Code §38-77-280), which mandate zero-deductible glass coverage for comprehensive policyholders, or Arizona (ARS 20-264), Connecticut, Massachusetts, Minnesota, and New York, which require insurers to at least offer optional zero-deductible glass riders.

Third, road debris — the leading cause of windshield damage — falls into a coverage gap by design. This damage is non-collision (so collision coverage does not apply), typically involves no identifiable at-fault driver (so mini-tort does not apply), and is not covered by PIP or PPI. Only optional comprehensive coverage addresses it, and Michigan imposes no special protections for glass within that coverage.

Michigan's system does offer one genuine, if narrow, advantage. The PPI parked-car mechanism (MCL 500.3121, via the MCL 500.3123(1)(a) exception) provides no-fault, no-deductible recovery up to $1,000,000 when a properly parked vehicle's glass is damaged by another motor vehicle. No other state offers an equivalent automatic, no-fault property damage benefit for parked vehicles. Additionally, Michigan has avoided the fraud-driven premium inflation that Florida experienced under its zero-deductible glass mandate, where Assignment of Benefits abuse by glass shops significantly inflated claims costs before Florida's 2023 reforms.

Conclusion

Michigan's no-fault system creates a uniquely fragmented coverage landscape for windshield and glass claims. The mandatory coverages — PIP (MCL 500.3107), PPI (MCL 500.3121), and residual liability (MCL 500.3131) — were designed to address bodily injury and third-party property damage, not damage to the insured's own vehicle. Glass claims fall almost entirely outside this framework, dependent on optional comprehensive coverage that Michigan neither mandates nor specifically regulates for glass.

The 2019 reform (PA 21) was silent on glass, and no subsequent legislative or regulatory action has addressed this gap. MCL 500.2110b remains the only Michigan statute that specifically names auto glass, providing anti-steering protections but nothing regarding coverage scope, deductibles, OEM parts, or ADAS recalibration. DIFS has issued no glass-specific guidance. ADAS recalibration, OEM glass requirements, and zero-deductible glass mandates all exist in statutory vacuums — areas where Michigan trails states like Arizona, Florida, and New York that have enacted targeted legislation.

The key insight for Michigan consumers is counterintuitive: despite living in a state with one of the nation's most comprehensive mandatory auto insurance systems, they have fewer statutory protections for windshield claims than consumers in most traditional at-fault states. The no-fault system's abolition of tort liability for vehicle property damage (MCL 500.3135(3)) removes a recovery avenue that exists elsewhere, while the absence of zero-deductible glass mandates leaves Michigan among approximately 42 states where standard deductibles apply without special glass protections. For a state whose roads generate significant windshield damage from construction, potholes, and harsh winters, this regulatory silence carries real economic consequences for consumers.
