Key Takeaways
- It Protects You When The Other Driver Cannot: Uninsured motorist coverage fills the gap when the at-fault driver has no insurance or insufficient coverage.
- Two Components Address Different Losses: Bodily injury and property damage are covered separately, and not every policy includes both automatically.
- Wisconsin Has A High Uninsured Driver Rate: Carrying this coverage is a practical necessity, not just an optional add-on for cautious drivers.
You stop at a red light. Another driver runs it, hits your car, and drives away. Or they stay, but their insurance lapsed three months ago. What is uninsured motorist coverage in that moment? It is a part of your own auto policy that steps in when the at-fault driver cannot pay for what they caused. In Wisconsin, where a meaningful percentage of drivers carry no insurance at all, this coverage is not a precaution reserved for worst-case thinking.
At Colonial Insurance Agency, we have helped Wisconsin drivers build auto policies that hold up in exactly these situations since 1975, working across multiple carriers to find coverage that fits both the risk and the budget.
This piece breaks down how uninsured motorist coverage works, what it pays for, and how it fits within your full policy.

The Gap That Appears When The Other Driver Has No Insurance
Not every driver on the road carries the coverage they are legally required to have. Here is what that means for you after an accident.
What is liability coverage, and why does its absence create a problem? Liability insurance is what the at-fault driver’s policy uses to pay for your injuries and vehicle damage after an accident they caused. When that driver has no liability coverage, or coverage that runs out before your losses are fully paid, the legal obligation to compensate you remains, but the financial means to do so often do not. That gap is where uninsured and underinsured motorist coverage becomes relevant.
The Wisconsin Uninsured Driver Reality
Studies consistently show that a significant percentage of drivers on Wisconsin roads are either uninsured or underinsured. State minimums are low enough that even drivers who technically carry liability coverage may not have enough to cover the costs of a serious accident. The financial exposure this creates for other drivers is real, and it does not disappear simply because you are not the one at fault.
Uninsured Versus Underinsured Motorist Coverage
These are two related but distinct protections. Uninsured motorist coverage applies when the at-fault driver has no insurance at all. Underinsured motorist coverage applies when the at-fault driver has insurance, but their limits are insufficient to cover the full extent of your losses. Many policies bundle the two together, but confirming that both are included in your policy, rather than assuming they are, is an important distinction.
For a broader concept, see “What is Liability Insurance?” which applies across different claim scenarios. Understanding the foundational layer of auto coverage helps clarify when uninsured motorist protection matters.
Hit-and-Run Scenarios
Most uninsured motorist policies also extend coverage to hit-and-run accidents where the at-fault driver cannot be identified. This is particularly relevant in urban and suburban Wisconsin driving environments, where hit-and-run incidents occur with some regularity. Confirming that your policy addresses this scenario before you need it is straightforward and worth having a conversation with your advisor about.
What Uninsured Motorist Coverage Pays For
The benefit covers two distinct categories of loss. Knowing what each one addresses prevents gaps in your expectations after a claim.
- Uninsured Motorist Bodily Injury: Covers medical expenses, lost wages, pain and suffering, and rehabilitation costs for you and your passengers when the at-fault driver has no insurance.
- Uninsured Motorist Property Damage: Covers repair or replacement costs for your vehicle when an uninsured driver causes the damage. Not all states require this component, and not all policies include it automatically.
- Underinsured Motorist Bodily Injury: Activates when the at-fault driver’s liability limits are exhausted before your medical costs are fully covered, paying the difference up to your own policy limits.
- Passenger Protection: Coverage extends to passengers in your vehicle at the time of the accident, not just the driver. This is particularly relevant for families and anyone who regularly carries passengers.
- Hit-And-Run Coverage: Most uninsured motorist policies cover losses caused by an unidentified driver, subject to policy terms and any reporting requirements your insurer specifies.
What is personal injury protection differs from uninsured motorist bodily injury in one key way: PIP pays regardless of fault and covers your own injuries from the moment of the accident. What is Personal Injury Protection covers the specifics of how that benefit works and when it applies alongside uninsured motorist coverage in the same claim.

How Uninsured Motorist Coverage Fits Within Your Full Policy
This coverage does not exist in isolation. Understanding how it interacts with your other coverage types reveals where you are protected and where gaps can still form.
The Relationship With Collision Coverage
What is collision coverage in relation to uninsured motorist property damage? Collision coverage pays for vehicle damage regardless of who caused it, while uninsured motorist property damage coverage applies only when an uninsured driver is at fault. If you carry collision coverage, you may be able to use it for vehicle repairs in an uninsured motorist situation, then allow your insurer to seek recovery from the at-fault driver on your behalf. What is Collision Coverage breaks down how that process works and when each coverage type takes precedence.
Stacking Versus Non-Stacking Policies
Some states allow drivers to stack uninsured motorist coverage across multiple vehicles on the same policy, effectively multiplying the available benefit. Wisconsin has specific rules around stacking that affect how much coverage is available per incident. Confirming whether your policy is stackable and what that means for your total available benefit is worth discussing with your advisor.
Where Gaps Still Form
Carrying uninsured motorist coverage does not mean every loss is fully addressed. If your uninsured motorist limits are set at the state minimum, a serious accident involving high medical costs or a total vehicle loss may still leave you short. Evaluating your limits relative to your actual financial exposure, including your vehicle’s value and what a major injury would cost without adequate coverage, is where the right limit becomes a financial decision rather than a default selection.
Deciding How Much Uninsured Motorist Coverage To Carry
The right coverage amount depends on your assets, your vehicle, and the level of financial risk you are willing to absorb after an accident.
- Match Limits To Your Liability Limits: A common starting point is carrying uninsured motorist limits that mirror your liability limits, creating a consistent level of protection on both sides of an accident.
- Consider Your Vehicle’s Value: If your vehicle is worth significantly more than your uninsured motorist property damage limit, the gap becomes your personal responsibility after a total loss.
- Factor In Your Health Coverage: Drivers with strong health insurance may have more flexibility on uninsured motorist bodily injury limits. Drivers without it should prioritize higher limits.
- Review Your Total Policy Structure: What is full coverage insurance in this context means understanding how all your coverage layers interact. What is Full Coverage Insurance covers liability, collision, comprehensive, and uninsured motorist coverage, which combine to form a complete auto policy.
- Work With An Independent Advisor: At Colonial Insurance Agency, we compare auto coverage options from multiple carriers for Wisconsin drivers, ensuring your uninsured motorist limits reflect your actual risk rather than a default minimum.

Final Thoughts
The at-fault driver’s insurance is supposed to cover your losses. When it does not exist or does not stretch far enough, your own policy is the only financial protection you have left.
