Uninsured motorist coverage can protect you when the at-fault driver has no insurance, not enough insurance, or cannot be identified in a covered hit-and-run situation. It is often overlooked because drivers focus on liability, collision, and comprehensive coverage first, but UM/UIM can be one of the most important protections after a serious accident.
NAIC notes that 49 states and Washington, D.C. require drivers to have auto liability insurance before legally driving, although requirements vary by state [1]. Yet uninsured drivers remain a real issue: Insurance Research Council data shows uninsured motorists rose from 12.6% in 2017 to 15.4% in 2023 [2].
If you are comparing protection, start with uninsured vs. underinsured motorist coverage, then review uninsured motorist coverage costs, essential uninsured motorist coverage limits, and how to add uninsured motorist coverage.
Protects Against Uninsured Drivers
UM coverage may help when another driver causes an accident and has no liability insurance to pay for your injuries or losses.
Helps With Coverage Gaps
UIM coverage may help when the at-fault driver has insurance, but their limits are too low to fully cover the claim.
Supports Financial Recovery
Depending on your policy and state, UM/UIM can help with medical expenses, lost wages, and other covered damages.
Why Uninsured Motorist Coverage Matters
Uninsured motorist coverage matters because you cannot control whether the other driver carries enough insurance. Even responsible drivers can be hit by someone who has no coverage, has allowed their policy to lapse, or only carries low minimum limits.
The financial impact can be serious. Medical bills, time off work, follow-up care, rehabilitation, vehicle repairs, and transportation costs can create a large burden. Without UM/UIM, you may need to rely on health insurance, collision coverage, personal savings, or direct recovery from the at-fault driver.
| Risk | Without UM/UIM | How UM/UIM May Help |
|---|---|---|
| Uninsured driver | You may need to pay out of pocket or pursue the driver directly. | UM may help pay covered injury-related losses up to your limits. |
| Underinsured driver | The other driver’s policy may run out before your losses are paid. | UIM may help cover the gap, subject to policy terms. |
| Hit-and-run | You may have no at-fault driver to recover from. | UM may apply in many states, but rules and reporting requirements vary. |
| Lost wages | Health insurance may not replace income. | UM/UIM may help with covered lost wages in some policies and states. |
Types of Uninsured Motorist Protection
UM/UIM protection can be structured differently depending on your state and insurer. Some policies focus on bodily injury, while others may include property damage options. Always check your declarations page and policy wording.
Common UM/UIM Types
- UMBI: Uninsured motorist bodily injury.
- UIMBI: Underinsured motorist bodily injury.
- UMPD: Uninsured motorist property damage, where available.
- Hit-and-run protection: May apply under UM rules in many states.
What to Check
- Your per-person and per-accident limits.
- Whether UMPD is included or optional.
- Whether stacking is allowed.
- Whether a police report is required for hit-and-run claims.
How Much Uninsured Motorist Coverage Do You Need?
There is no single perfect limit for every driver. A practical starting point is to compare UM/UIM limits with your bodily injury liability limits. If you would want strong protection for someone else when you cause an accident, it often makes sense to consider similar protection for yourself when another driver is uninsured or underinsured.
| Limit Level | May Fit | Important Note |
|---|---|---|
| State minimum or low limits | Drivers with very tight budgets. | Better than no coverage, but serious injuries can exceed low limits quickly. |
| $50,000 / $100,000 | Drivers wanting more than minimum protection. | A more realistic midpoint for many households. |
| $100,000 / $300,000 | Frequent drivers, families, and drivers with income to protect. | Often compared by drivers who want stronger financial protection. |
| Higher limits | Higher-income households or drivers with larger assets. | Ask how UM/UIM coordinates with umbrella or excess coverage. |

Financial Implications of Not Having UM Coverage
Not carrying UM/UIM can expose you to costs that are difficult to recover from the at-fault driver. If the driver has no insurance, they may also have limited assets. That means a court judgment may not translate into fast or meaningful payment.
Medical Bills
Emergency care, imaging, surgery, physical therapy, and follow-up appointments can create large costs after a crash.
Lost Income
Time away from work can create stress even if health insurance helps with some medical bills.
Vehicle and Transportation Costs
Repairs, towing, rental cars, and rideshare costs may add pressure while the claim is pending.

Common Misconceptions About Uninsured Motorist Coverage
Misconceptions
- “Health insurance is enough.”
- “Full coverage always includes UM/UIM.”
- “Uninsured drivers are rare.”
- “Minimum limits are always enough.”
- “I only need UM in big cities.”
Reality
- Health insurance may not replace lost wages or handle every loss.
- “Full coverage” is not a standardized term.
- Uninsured motorist rates vary, but the risk is real nationwide.
- Serious injuries can exceed minimum limits quickly.
- UM/UIM risk can exist in urban, suburban, and rural areas.
How to Add UM Coverage to an Existing Policy
Adding uninsured motorist coverage is usually a policy-service request. Contact your insurer or agent and ask what UM/UIM limits are available, whether UMPD is offered, and whether the coverage can be added mid-term or only at renewal.
- Open your declarations page and check whether UM/UIM already appears.
- Ask for quotes at multiple limit levels.
- Confirm whether your state allows stacking.
- Ask whether hit-and-run claims require a police report.
- Compare the added cost against the financial risk of not carrying the coverage.

Final Thoughts
Uninsured motorist coverage is important because it protects against a risk you cannot fully control: another driver’s failure to carry enough insurance. Even if you drive safely, you can still be hit by someone who has no coverage, low limits, or no identifiable insurance information after a hit-and-run.
Before choosing limits, compare your UM/UIM options, check state rules, review your financial exposure, and ask how much it costs to raise limits. A modest premium increase may provide meaningful protection after a serious accident.
