Quick takeaway: Uninsured motorist (UM) coverage is often one of the more cost-efficient protections on an auto policy, but the price depends heavily on your state, your chosen limits, and your overall rating factors. The goal is to match “cheap” with “usable” — limits that would actually help if the other driver can’t pay.
Understanding the costs associated with uninsured motorist coverage matters because it protects you when the at-fault driver has no insurance — or not enough insurance — to cover injuries and related losses. In many states, UM can also apply to certain hit-and-run situations (policy conditions vary), which is one reason many drivers consider it a practical add-on rather than a luxury.
The price you pay for uninsured motorist coverage depends on your state, your driving profile, the limits you select, and the insurer’s rating rules. For a state-focused breakdown, review uninsured motorist coverage costs in your area. Looking at state-specific context helps you pick limits that match both your budget and your real exposure.
For many drivers, uninsured motorist coverage is a cost-effective way to avoid major out-of-pocket bills after a serious accident. This is especially relevant in areas where uninsured-driver rates are higher or where minimum required liability limits are low.
Understanding Uninsured Motorist Coverage
Uninsured motorist coverage is designed to help when you are hit by a driver who has no liability insurance. Underinsured motorist coverage (UIM) addresses a different problem: the at-fault driver has insurance, but the limits are too low to cover the injuries and losses involved. Depending on your state and insurer, these protections may be offered separately or packaged together.
Many policies split UM into:
- UMBI (Uninsured Motorist Bodily Injury): May help with medical bills, lost wages, and (in some cases) pain and suffering up to your limits.
- UMPD (Uninsured Motorist Property Damage): May help with vehicle damage in some states, sometimes with a deductible (availability varies).
UM/UIM is different from liability coverage. Liability protects other people from damage you cause. UM/UIM protects you and your passengers when the other driver can’t pay. If you want a side-by-side breakdown, see uninsured vs. underinsured motorist coverage.
What UM Coverage Typically Pays For (and What It Doesn’t)
UM/UIM can be a strong financial backstop, but it is not a “blank check.” What’s covered depends on your state’s rules and your policy language. Common examples include:
- Medical expenses related to covered injuries
- Lost wages and, in some cases, reduced earning capacity
- Pain and suffering (where allowed and where supported by documentation)
- Vehicle damage only if UMPD is available/selected or if you use collision coverage instead
UM typically does not replace collision coverage in every state, and it may not cover every out-of-pocket cost you face after a crash (for example, deductibles, certain exclusions, or non-covered expenses). This is why reviewing your declarations page and policy forms is essential.
The Factors Influencing the Cost of Uninsured Motorist Coverage
The cost of uninsured motorist coverage is driven by many of the same factors that affect your overall premium, plus a few that are especially relevant to UM/UIM exposure. Here are the most common pricing drivers:
| Factor | How It Can Affect Your Cost |
|---|---|
| State rules and uninsured-driver environment | Where uninsured driving is more common, UM claims may be more frequent, which can influence pricing. |
| UM/UIM limits you choose | Higher limits generally cost more but provide better protection when injuries are serious. |
| Deductibles (mostly for property damage, if offered) | A higher deductible can reduce premium, but increases your out-of-pocket cost after a claim. |
| Driving record and claims history | Accidents/violations can raise overall premium and may influence UM pricing indirectly. |
| Vehicle, garaging location, and annual mileage | Higher exposure (more time on the road, higher-traffic areas) can increase premium. |
| Insurer pricing and discounts | Each carrier rates differently, so the same driver can see meaningful quote differences. |
Age, household drivers, and prior lapses can also affect total pricing. For a broader view of why premiums vary by company, see comparing insurance premiums for the best rates.
How Much Coverage Should You Buy?
A practical rule many agents use is to keep UM/UIM limits close to your bodily injury liability limits, because the potential injury costs after a crash can be similar whether you caused the accident or someone else did. The “right” limit depends on how a serious accident would affect your:
- Income and ability to work
- Savings and emergency fund
- Household obligations (rent/mortgage, dependents, medical needs)
- Health insurance deductibles and out-of-pocket maximums
If you want a state-and-budget focused look at what limits can cost, start with uninsured motorist coverage costs in your area and compare at least a few carriers.
Comparing Insurance Providers
Because insurers weigh risk differently, comparing quotes is one of the best ways to manage UM cost. Don’t assume your current company is automatically best, especially if you haven’t shopped recently.
When comparing, look beyond price and check:
- Whether UM and UIM are offered, and how limits can be set
- Whether UMPD is available (or whether collision will handle car damage instead)
- How claims are handled (communication, timelines, documentation expectations)
- Discounts that lower total premium
For a practical starting shortlist, review top affordable auto insurance providers and use those names to request comparable quotes.
Long-Term Financial Benefits of UM Coverage
Although uninsured motorist coverage adds premium, it can protect you from much larger losses. Injuries can cause medical costs, time away from work, and ongoing treatment or rehab. Without UM/UIM, recovering those losses often means relying on health insurance alone (which doesn’t cover everything) or pursuing the at-fault driver — and collection may be difficult if they have few assets.
Having UM/UIM in place usually simplifies the process because you work with your own insurer under your policy’s rules. For context on how uninsured situations can hit your finances, see the financial impacts of driving uninsured.
Common Misconceptions About UM Coverage
- “My health insurance is enough.” Health insurance may help with medical bills, but it generally won’t replace lost wages or address non-economic damages where applicable.
- “I only need UM in high-crime areas.” Uninsured driving exists everywhere—urban, suburban, and rural—and policies lapse for many reasons.
- “I’ll deal with it if it happens.” Pursuing an uninsured driver after a crash can be slow and may not lead to meaningful recovery if they can’t pay.

How to File a Claim for Uninsured Motorist Coverage
If you suspect the other driver is uninsured or underinsured, your documentation matters. Most insurers follow a similar process:
- Report the crash to law enforcement when appropriate and get the report number
- Take photos, collect witness contact info, and document injuries early
- Notify your insurer promptly and ask whether UM/UIM may apply
- Save medical bills, repair estimates, and proof of missed work

Finding Affordable Uninsured Motorist Coverage
UM/UIM is often affordable, but the best price comes from shopping smart and choosing limits intentionally. Try these strategies:
- Quote UM/UIM limits that align with your liability limits when possible
- Ask about discounts (safe driver, multi-car, bundling, good student, telematics where appropriate)
- Consider deductible tradeoffs for property damage where available
- Reduce non-essential add-ons before cutting core protections

Monitoring Changes in Your Coverage Needs
UM/UIM needs can change after life events like moving, adding a driver, buying a more expensive car, or changes in household income. An annual policy review can help you confirm limits, confirm discounts, and avoid accidental coverage gaps.

FAQs About the Cost of Uninsured Motorist Coverage
Is uninsured motorist coverage required in every state?
No. Some states require it, some require insurers to offer it (but allow you to reject it in writing), and others make it optional. Check your state rules and your declarations page.
How much uninsured motorist coverage should I buy?
Many agents recommend matching your UM/UIM limits to your bodily injury liability limits when possible. The best choice depends on income, savings, health insurance, and how much financial risk you can absorb.
Does UM coverage make my policy much more expensive?
Often, UM/UIM is a smaller portion of the total premium than collision or comprehensive. Your price depends on state, limits, and your rating factors.
Can I add uninsured motorist coverage to an existing policy?
In many cases, yes. Insurers may allow changes mid-term or at renewal, subject to state rules and underwriting.
Conclusion
Understanding the costs and benefits of uninsured motorist coverage is a key part of building a realistic auto insurance plan. UM/UIM can protect you from medical bills, lost wages, and other losses when the at-fault driver has insufficient coverage—or none at all.
By comparing quotes, selecting limits intentionally, and reviewing your policy at least once a year, you can find coverage that balances affordability with meaningful protection.
