Uninsured and underinsured motorist coverage in Michigan protects you when the driver who caused your accident has no insurance or does not have enough coverage to fully compensate you for your injuries.
These optional coverages can pay for pain and suffering, excess medical expenses, and other losses not covered under Michigan’s no-fault system.
Without them, your recovery may be limited to the at-fault driver’s policy limits, which are often insufficient in serious cases.
Uninsured motorist coverage and underinsured motorist coverage serve a similar purpose, but they apply in very different situations. Understanding that distinction is critical when deciding how to protect yourself after a car accident in Michigan.
Both coverages are designed to address a common problem. The driver who caused your accident may have no insurance at all, or may carry liability coverage that is not enough to fully compensate you for your injuries.
The difference between these two types of coverage determines when each applies and how your recovery works. Knowing how they fit together can make a significant difference in whether you are fully protected after a serious crash.

ToggleUninsured and underinsured motorist coverage protects you when the driver who caused your accident has no insurance or does not carry enough liability coverage to fully compensate you for your injuries. In Michigan, this situation is more common than most drivers realize.
Because auto insurance is expensive, many drivers carry only the minimum bodily injury liability limits allowed under MCL 500.3009. While these limits satisfy the legal requirement, they are often far too low to cover serious injuries.
The reality is simple. When a driver with minimum coverage causes a serious crash, there is often not enough insurance available to fully compensate the injured person for pain and suffering or excess economic losses.
That gap is where accident victims are often left without full financial recovery.
Under Michigan’s no-fault system, your own insurance will cover certain medical expenses and wage loss benefits. But it does not guarantee full compensation. It does not automatically cover pain and suffering, and it may not cover all medical expenses depending on the policy you selected.
In many cases, uninsured and underinsured motorist coverage is the only way to close that gap. It allows your own insurance company to step in and provide the compensation the at-fault driver should have been able to pay.
This is not just optional coverage. In many cases, it is the only real way to fully protect yourself after a serious car accident in Michigan.
Uninsured and underinsured motorist coverage serve a similar purpose. Both are designed to protect you when the driver who caused your accident does not have adequate insurance. But they apply in different situations, and understanding that difference is critical.
📊 Uninsured vs Underinsured Motorist Coverage
| Coverage Type | When It Applies | What It Covers | Key Risk Without It |
|---|---|---|---|
| Uninsured Motorist (UM) | The at-fault driver has no insurance or cannot be identified, such as in a hit-and-run accident | Pain and suffering, excess medical expenses, and other damages | No recovery available from the at-fault driver |
| Underinsured Motorist (UIM) | The at-fault driver has insurance, but the policy limits are too low to fully compensate you | Remaining damages after the at-fault driver’s policy is exhausted | A significant gap between damages and available insurance |
Uninsured Motorist Coverage (UM)
Uninsured motorist coverage applies when the at-fault driver has no insurance or cannot be identified, such as in a hit-and-run accident. In these situations, there is no liability insurance available to compensate you, which means your recovery depends entirely on your own policy. To learn more about how these claims work, see our guide on uninsured motorist coverage in Michigan.
Underinsured Motorist Coverage (UIM)
Underinsured motorist coverage applies when the at-fault driver has insurance, but the available policy limits are not enough to fully compensate you for your injuries. This is common in Michigan, where many drivers carry only the minimum liability limits allowed under MCL 500.3009. Learn more about how these claims work in our guide on underinsured motorist coverage in Michigan.
The distinction is straightforward. Uninsured motorist coverage applies when there is no insurance. Underinsured motorist coverage applies when there is not enough.
In Michigan, both situations occur more often than most drivers expect. Many drivers either carry no insurance at all or purchase only the minimum liability limits allowed under MCL 500.3009. While those limits may meet the legal requirement, they are often inadequate in serious injury cases.
The practical consequence is the same. Without UM or UIM coverage, your ability to recover compensation depends entirely on the other driver’s insurance. When that coverage is missing or insufficient, you may be left without a meaningful path to full financial recovery.
For that reason, most drivers need both.
Uninsured and underinsured motorist coverage are not required under Michigan law. They are optional coverages that must be purchased as part of your auto insurance policy.
In practice, most drivers should carry both.
Without this coverage, your ability to recover compensation depends entirely on the at-fault driver’s insurance. In many cases, that is not enough.
The recommended uninsured and underinsured motorist coverage in Michigan is at least $500,000 per person and $1,000,000 per accident.
Both coverages should be carried at the same limits to fully protect you in the event of a serious accident.
Fortunately, this coverage is relatively inexpensive compared to the level of protection it provides.
Uninsured motorist coverage applies when the at-fault driver has no insurance or cannot be identified. Underinsured motorist coverage applies when the driver has insurance, but the policy limits are not enough to fully compensate you for your injuries.
