Uninsured & Underinsured Motorist Claims in Michigan

Michigan consistently ranks among the states with the highest rates of uninsured drivers in the country. Studies estimate that roughly 20 to 25 percent of Michigan motorists carry no auto insurance at all. If you are injured by a driver who has no coverage or insufficient coverage, uninsured and underinsured motorist (UM/UIM) protection may be your only path to full compensation. Understanding how these claims work under Michigan law is critical for every driver in the state.

What Is Uninsured and Underinsured Motorist Coverage?

Uninsured motorist (UM) coverage pays for your injuries and damages when the at-fault driver carries no liability insurance whatsoever. Underinsured motorist (UIM) coverage applies when the at-fault driver does have insurance, but their policy limits are too low to cover the full extent of your losses. Together, UM/UIM coverage acts as a safety net provided by your own insurance policy, stepping in to cover the gap left by an irresponsible or inadequately insured driver.

In Michigan, UM/UIM coverage is optional but strongly recommended. Your insurer is required to offer it to you when you purchase or renew a policy, but you may decline it in writing. Given the state's high uninsured driver rate and the fact that Michigan's minimum bodily injury liability limits are just $50,000 per person and $100,000 per accident, carrying UM/UIM protection is one of the smartest financial decisions a Michigan driver can make.

Michigan's Insurance Requirements and the Uninsured Driver Problem

Michigan requires all drivers to maintain no-fault personal injury protection (PIP) and residual bodily injury liability coverage. However, despite these requirements, a significant portion of the driving population remains uninsured. High insurance premiums in cities like Detroit, Flint, and Pontiac drive many residents to let their coverage lapse. When an uninsured driver causes a collision, the injured party cannot collect bodily injury liability compensation from a nonexistent policy. Without UM coverage on your own policy, you may have no source of recovery for pain and suffering, lost wages beyond PIP limits, or other non-economic damages.

How Underinsured Motorist Coverage Applies

Underinsured motorist coverage is triggered when the at-fault driver's liability limits are exhausted but your damages exceed that amount. For example, if the negligent driver carries only the state minimum of $50,000 in bodily injury coverage and your injuries result in $200,000 in damages, UIM coverage on your own policy can make up the difference up to your policy limits. In Michigan, you generally must exhaust the at-fault driver's available liability coverage before your UIM benefits become available. This means settling with or obtaining a judgment against the at-fault party first, then turning to your own insurer for the remaining balance.

Stacking of UM/UIM Policies

Stacking refers to the ability to combine the UM/UIM limits from multiple policies to increase your total available coverage. In Michigan, whether you can stack depends on your specific policy language and the number of vehicles on your policy. If your policy covers multiple vehicles, you may be able to stack the UM/UIM limits for each vehicle, effectively multiplying your available coverage. For instance, if you carry $100,000 in UM coverage on a policy insuring three vehicles, stacking could provide up to $300,000 in total UM protection. However, many Michigan insurers include anti-stacking clauses in their policies. An experienced attorney can review your policy language to determine whether stacking is available to you and maximize your recovery.

The Arbitration Process for UM Claims

Most Michigan UM/UIM policies contain a mandatory arbitration clause. This means that if you and your insurer cannot agree on the value of your claim, the dispute is resolved through binding arbitration rather than a jury trial. In arbitration, one or more neutral arbitrators hear evidence from both sides and issue a decision. The process is generally faster and less formal than litigation, but it carries its own challenges. Your insurer will be represented by experienced defense counsel, and the arbitration decision is typically final with very limited grounds for appeal. Having skilled legal representation during the arbitration process is essential to ensure your injuries are properly valued and your rights are protected.

Hit-and-Run Accidents and UM Coverage

Hit-and-run collisions present a unique challenge because the at-fault driver flees the scene and may never be identified. Under Michigan law, a hit-and-run driver is treated as an uninsured motorist for the purpose of UM claims. This means your own UM coverage can pay for your injuries even when the responsible party is unknown. However, there are important requirements you must meet. You must report the hit-and-run to police promptly, typically within 24 hours. You must also be able to demonstrate that the accident was caused by physical contact with another vehicle or, in some cases, that you took reasonable steps to identify the fleeing driver. Preserving evidence such as dashcam footage, witness statements, and photographs of vehicle damage strengthens your claim significantly.

How to File a UM/UIM Claim with Your Own Insurer

Filing a UM/UIM claim involves notifying your own insurance company that you were injured by an uninsured or underinsured driver and that you intend to seek benefits under your policy. Key steps in the process include:

• Report the accident promptly. Notify your insurer as soon as possible after the crash, even before you know the at-fault driver's insurance status.
• Document your injuries and damages. Gather medical records, bills, proof of lost income, and evidence of pain and suffering.
• Confirm the at-fault driver's insurance status. Obtain a police report and request insurance information. If the other driver is uninsured or underinsured, notify your carrier in writing.
• Submit a formal demand. Present your claim with supporting documentation to your insurer, specifying the compensation you are seeking.
• Negotiate or proceed to arbitration. Your insurer may offer a settlement. If the offer is inadequate, the dispute moves to binding arbitration as outlined in your policy.

Be aware that your own insurer is not on your side in this process. Although you pay premiums for UM/UIM coverage, when a claim is filed, the insurance company's goal is to minimize the payout. They may dispute the severity of your injuries, question causation, or argue that your damages are lower than claimed.

Why UM/UIM Coverage Is Essential in Michigan

Given Michigan's combination of high uninsured driver rates, relatively low minimum liability requirements, and expensive medical care, UM/UIM coverage is not a luxury but a necessity. Without it, an accident caused by an uninsured driver could leave you responsible for hundreds of thousands of dollars in medical expenses, lost income, and other damages with no way to recover those losses. UM/UIM coverage is typically affordable relative to the protection it provides, often adding only a modest amount to your annual premium. Drivers should consider purchasing UM/UIM limits that match their bodily injury liability limits to ensure comprehensive protection.

If you have been injured by an uninsured or underinsured driver in Michigan, or if you are unsure whether your policy provides adequate UM/UIM protection, consulting with an experienced personal injury attorney can help you understand your options and pursue the full compensation you deserve.
