Here's a scenario that happens more often than you'd think: you're stopped at a red light in Columbus when someone rear-ends you. You exchange information, but when you try to file a claim, you discover the other driver has no insurance. Now what? If you don't have uninsured motorist coverage, you might be stuck paying your own medical bills and repair costs out of pocket—even though the accident wasn't your fault.

In Ohio, nearly one in five drivers doesn't carry insurance. That's a sobering statistic when you consider how many cars you pass on your daily commute. Uninsured motorist coverage is your financial safety net for these situations, and understanding how it works could save you thousands of dollars.

What Is Uninsured Motorist Coverage?

Think of uninsured motorist coverage as a backup plan. When another driver causes an accident and doesn't have insurance to pay for your damages, your UM coverage steps in to cover you. It pays for medical expenses, lost wages, pain and suffering, and other costs you'd normally recover from the at-fault driver's liability insurance.

Ohio doesn't require you to buy this coverage, but here's the catch: your insurance company must offer it to you. If you didn't explicitly reject it in writing when you purchased your policy, there's a good chance you already have it. Check your declarations page to be sure.

Underinsured Motorist Coverage: The Other Half of the Equation

Underinsured motorist coverage handles a slightly different problem. Let's say someone hits you and they do have insurance, but their policy limits are only $25,000 per person—Ohio's minimum requirement. If your medical bills total $75,000, their insurance maxes out at $25,000, leaving you $50,000 short. That's where UIM coverage comes in.

Your underinsured motorist coverage pays the difference, up to your policy limits. If you have $100,000 in UIM coverage, your insurance would cover that $50,000 gap. One important detail: the total amount paid by both insurance companies combined cannot exceed your UIM limit. So in this example, you'd receive $25,000 from the at-fault driver's policy plus $50,000 from yours, totaling $75,000.

Understanding Coverage Limits in Ohio

Ohio law sets specific rules about how much UM/UIM coverage you can buy. You can purchase coverage up to the same limits as your liability insurance, but you cannot exceed those amounts. For example, if you carry $50,000 per person in liability coverage, you can buy up to $50,000 per person in uninsured motorist coverage.

Most Ohio drivers start with Ohio's minimum liability requirements: $25,000 per person for bodily injury, $50,000 per accident, and $25,000 for property damage. This is expressed as 25/50/25. But here's the uncomfortable truth—those minimums often aren't enough to cover serious accidents. A single night in the hospital can easily cost more than $25,000, and if you're seriously injured, your medical bills could reach six figures.

Consider increasing both your liability and UM/UIM limits to at least $100,000 per person and $300,000 per accident. The additional premium is typically modest compared to the financial protection you gain. You can also explore umbrella policies for even higher limits if you have significant assets to protect.

Why This Coverage Matters More Than You Think

The statistics are eye-opening. According to the Insurance Research Council, 18.5% of Ohio motorists were uninsured in 2023. That means if you're in an accident with another vehicle, there's nearly a one-in-five chance the other driver can't pay for the damage they cause.

Even when drivers do carry insurance, many only purchase the state minimum. If you're seriously injured by someone with minimal coverage, you could face enormous out-of-pocket expenses. Medical bills, lost income from missing work, ongoing physical therapy—these costs add up fast. Without UM/UIM coverage, you'd need to sue the at-fault driver personally to recover these expenses. And here's the harsh reality: if they couldn't afford adequate insurance, they probably don't have assets you can collect from anyway.

How to File an Uninsured Motorist Claim

If you're hit by an uninsured or underinsured driver, follow these steps to protect your rights. First, call 911 and request a police report. This documents the accident and confirms the other driver's insurance status. Take photos of the damage, get witness contact information, and seek medical attention even if you feel fine—some injuries don't show symptoms immediately.

Next, notify your insurance company that the other driver was uninsured or underinsured. You'll file the claim with your own insurer, not the other driver's. An adjuster will investigate your claim, reviewing medical records, lost wage documentation, and other evidence of your damages. They'll calculate what you're owed based on your policy limits.

Here's some good news: filing an uninsured motorist claim typically won't increase your insurance rates. You're claiming under coverage you already paid for, and the accident wasn't your fault. You generally have two years from the accident date to file your claim in Ohio, though some policies have shorter deadlines, so don't delay.

Getting the Right Coverage for Your Situation

Pull out your current auto insurance policy and check your declarations page. Look for uninsured motorist and underinsured motorist coverage. If you don't see it listed, or if your limits match Ohio's minimums, it's time to have a conversation with your insurance agent.

Ask about the cost difference between your current coverage and higher limits like 100/300/100. You might be surprised at how affordable it is to significantly increase your protection. Also inquire about stacking versus non-stacking coverage if you insure multiple vehicles—stacking allows you to combine limits from all your cars for greater protection.

Uninsured motorist coverage isn't just another line item on your insurance bill. It's financial protection against a very real risk. With one in five Ohio drivers on the road without insurance, this coverage could be the difference between a manageable inconvenience and a financial disaster. Take a few minutes today to review your policy and make sure you're adequately protected.

Frequently Asked Questions

Is uninsured motorist coverage required in Ohio?

+

No, Ohio doesn't require uninsured motorist coverage. However, insurance companies must offer it to you when you purchase a policy, and you must reject it in writing if you don't want it. Given that nearly 18.5% of Ohio drivers are uninsured, most experts strongly recommend purchasing this coverage.

How much does uninsured motorist coverage cost in Ohio?

+

Uninsured motorist coverage is typically bundled into full coverage policies and adds a modest amount to your premium. The exact cost varies based on your limits, driving history, and location, but increasing from minimum coverage to higher limits like 100/300 often costs less than you'd expect—sometimes just a few dollars per month for significantly better protection.

What's the difference between uninsured and underinsured motorist coverage?

+

Uninsured motorist coverage pays when the at-fault driver has no insurance at all. Underinsured motorist coverage kicks in when the at-fault driver has insurance, but their policy limits are too low to cover your full damages. Both protect you from out-of-pocket expenses when other drivers can't pay for the harm they cause.

Will filing an uninsured motorist claim raise my insurance rates?

+

Generally no. Since you're filing a claim under your own policy for an accident that wasn't your fault, most insurance companies won't raise your rates for an uninsured motorist claim. You're simply using coverage you already paid for to protect yourself from an uninsured driver.

How much UM/UIM coverage should I buy in Ohio?

+

While you can match Ohio's minimum liability limits of 25/50/25, consider purchasing at least 100/300/100 coverage. Medical costs from serious accidents easily exceed $25,000, and higher limits provide much better protection. You can buy UM/UIM coverage up to the same limits as your liability coverage, so if you increase liability, you can increase UM/UIM to match.

How long do I have to file an uninsured motorist claim in Ohio?

+

Ohio's statute of limitations gives you two years from the accident date to file an uninsured motorist claim. However, some insurance policies have shorter deadlines written into the contract, so notify your insurer immediately after an accident and review your policy's specific timeframes to avoid missing important deadlines.
