Choosing the right uninsured motorist (UM) coverage is one of the most important protection decisions in an auto policy. Many drivers are uninsured, and even “insured” drivers may carry only minimum limits that don’t go far after a serious crash. The Insurance Information Institute highlights ongoing uninsured motorist concerns across the U.S., which is exactly why UM coverage exists. [1]

The challenge is that insurers price and structure UM/UIM differently. Instead of calling multiple companies one-by-one, using reliable comparison tools can help you view options side by side and understand what you’re paying for. If you want a deeper explanation of UM vs. UIM before shopping, see our guide to
uninsured vs. underinsured motorist coverage.
NerdWallet also provides a helpful overview of how UM/UIM works. [2]

Below you’ll find the best comparison tools for uninsured motorist coverage, plus a practical checklist for comparing UM limits, add-ons, and claims reputation. For an advanced side-by-side breakdown of policy structures, you may also want our guide on
comparing uninsured and underinsured motorist coverage options.

Why Uninsured Motorist Coverage Matters

Uninsured motorist coverage helps protect you if you’re hit by a driver who has no insurance. Underinsured motorist coverage (often paired with UM) helps when the at-fault driver has insurance, but not enough to cover the damage. Depending on your state and policy type, UM/UIM can help pay for medical bills, lost wages, and other injury-related costs. [2]

Protecting Your Finances (Not Just Meeting Minimums)

State minimums can be surprisingly low compared with modern medical costs and repair bills. That’s why many drivers choose UM/UIM limits that match their liability limits, then increase from there if they have assets, limited savings, or a higher-risk driving pattern (commuting, heavy traffic, frequent passengers). [2]

Comparison tools help you focus on the real question: which policy gives the best protection for the price. The goal isn’t “cheapest UM,” it’s “best value UM”—limits, options, and claims reliability aligned with your risk.

Top Comparison Tools for Uninsured Motorist Coverage

Most tools compare full auto policies, but you can usually adjust UM/UIM choices during the quote flow (or immediately after). Here are the most useful tools, grouped by how people actually shop:

Best for multi-quote comparison (one form, multiple insurers)

• The Zebra — A dedicated comparison platform designed to help you compare multiple insurers in one process. Use it to shortlist carriers, then verify UM/UIM limits inside each quote. :contentReference[oaicite:3]{index=3}
• Insurify — Positions itself as a digital agent offering real-time quotes from many partner insurers, which can be helpful for quickly testing different coverage levels and price ranges. :contentReference[oaicite:4]{index=4}
• Compare.com — A quote comparison site that advertises quotes from a large set of insurance companies; useful for fast pricing checks and limit changes, then you can confirm details directly with the insurer. :contentReference[oaicite:5]{index=5}

Best for quoting directly with a specific insurer

• Allstate — Helpful if you want to understand UM coverage options and then run a direct quote through one insurer’s flow. Allstate publishes UM guidance and provides online tools for exploring coverage needs. :contentReference[oaicite:6]{index=6}

Best for education + shopping strategy

• NerdWallet — Strong for learning how UM/UIM works and comparing insurance shopping approaches (comparison sites vs. direct vs. agent). :contentReference[oaicite:7]{index=7}
• Insure.com — Useful research tools and calculators; better for understanding coverage levels and pricing context than for guaranteed multi-quote results. :contentReference[oaicite:8]{index=8}
• DMV.org — Helpful for state-level explanations of uninsured motorist coverage and what may be required or offered where you live. :contentReference[oaicite:9]{index=9}
• Forbes Advisor — Best used as an editorial research hub (reviews, comparisons, educational explainers) while you get quotes elsewhere. :contentReference[oaicite:10]{index=10}

At-a-Glance Comparison of Popular Tools

Key Factors to Compare (So You Don’t Miss the Important Stuff)

• UM/UIM limits: Many drivers choose limits that match their liability coverage, then consider higher limits if they have assets or limited savings. :contentReference[oaicite:18]{index=18}
• UMPD availability: Not every state/policy offers it. If your car’s value is meaningful to you, confirm whether UM property damage is included or optional.
• Stacking rules: If stacking is allowed, it can meaningfully increase protection. Confirm eligibility and cost.
• Exclusions and claim steps: Ask how the insurer handles proof of uninsured status, hit-and-run rules, and documentation requirements.
• Claims satisfaction: When you need UM coverage, claims handling matters. (Industry studies can help you benchmark customer satisfaction.) [3]

How to Use Comparison Tools Effectively

The best approach is to compare “apples to apples.” If one quote uses low UM limits and another uses high limits, the cheaper policy may simply be weaker. Keep the coverage settings consistent while you compare.

Step-by-Step (Fast, Clean, and Repeatable)

1. Gather what you need: Driver’s license info, VIN, current coverage, mileage, address/ZIP, and prior claims (if any). Tools and insurers commonly ask for these details to provide accurate quotes. :contentReference[oaicite:19]{index=19}
2. Set a baseline: Start with UM/UIM limits that match your liability limits, then price-check one step higher so you can see the real cost difference. :contentReference[oaicite:20]{index=20}
3. Run 2–3 methods: Use one comparison site + at least one direct insurer quote. This reduces the odds you miss a better rate or a better UM structure.
4. Record the details: For each quote, note UM/UIM limits, deductibles (if any), UMPD availability, stacking, rental/roadside add-ons, and total premium.
5. Verify before you buy: Once you pick your top 1–2, confirm the exact UM/UIM language and endorsements with the insurer or a licensed agent.

Agent Insight (From the Author)

Common Misconceptions About Uninsured Motorist Coverage

• “I only need UM in high-risk states.” Uninsured and underinsured drivers exist everywhere, and minimum limits often don’t go far after serious injuries. [1]
• “UM is only for catastrophic crashes.” Even moderate injuries can lead to medical bills and time off work. UM/UIM helps close that gap. [2]
• “Health insurance makes UM unnecessary.” Health insurance may not cover lost wages or other damages UM/UIM can address, and deductibles/copays can still be significant.

FAQ

What is uninsured motorist coverage?

Uninsured motorist coverage helps protect you if you’re hit by a driver with no insurance. It commonly helps with injury-related costs (and in some cases property damage, depending on the state/policy). [2]

Is uninsured motorist coverage mandatory?

It depends on your state. Some states require UM/UIM, others make it optional but require insurers to offer it. DMV.org provides a state-level overview and explains why many states require it. :contentReference[oaicite:22]{index=22}

Do comparison tools show UM/UIM details clearly?

Some do, some don’t. The best approach is to use comparison tools to narrow down carriers and pricing, then verify UM/UIM endorsements and options directly with the insurer or a licensed agent before purchase.

Can I change UM/UIM limits later?

Usually yes—either at renewal or sometimes mid-term. Ask about the effective date, underwriting review, and how the premium changes before you make the adjustment.

How do I know if my UM/UIM limits are high enough?

Many drivers start by matching UM/UIM limits to their liability limits, then consider higher limits if they have assets to protect, limited savings, frequent passengers, or higher exposure (commuting). A licensed agent can help you stress-test limits against real-world medical and income scenarios. [2]

Conclusion

Uninsured motorist coverage is a critical piece of a well-built auto policy. When the at-fault driver has no insurance (or not enough), UM/UIM can be what prevents a crash from turning into a long-term financial problem. [1]

The fastest way to shop smarter is to compare quotes with consistent UM/UIM settings, shortlist the best-value options, and then confirm details directly with the insurer before you buy. If you want to refine your decision further, revisit our guide on
