Do I Have Enough Auto Insurance?

Last Updated on December 31, 2025

Having the right amount of car insurance is a balancing act. Too little coverage can put your savings, income, and assets at risk after a serious crash. Too much coverage can mean you’re paying for protections you’re unlikely to use.

The good news: you can usually tell whether you’re underinsured or overinsured by doing a quick “coverage audit” on your declarations page. Use the guide below to check your limits, deductibles, and optional coverages—then adjust your policy to fit your real-world risk.

Key Takeaways

• “Enough” car insurance means meeting state and lender requirements while choosing limits that protect your finances in a serious accident.
• If you have savings, home equity, or steady income, state minimum liability limits are often too low to fully protect you.
• Collision and comprehensive should be reviewed as your car depreciates—keeping full coverage on a low-value car can be a common overpayment.
• Uninsured/underinsured motorist coverage and PIP/MedPay can be crucial when the other driver can’t pay or when medical bills add up fast.

Start With What’s Required (State Laws and Lenders)

Before you decide what’s “enough,” make sure you meet the minimums you’re required to carry.

State laws: Nearly every state requires some level of car insurance (with special rules in places like New Hampshire). Most states require liability insurance, which typically includes bodily injury liability and property damage liability. Minimum limits can change over time, so it’s smart to review your state’s current requirements once a year. See required limits by state here.

Lenders and lessors: If your vehicle is financed, your lender usually requires more than the state minimums. Many require comprehensive and collision to protect the vehicle while the loan is outstanding. If you’re financing, review these basics on minimum coverage for a financed car and how collateral protection insurance works if coverage lapses.

A Quick “Enough Insurance” Checklist

Pull up your declarations page and answer these questions:

1. Would your liability limits protect your income and assets if you caused a serious accident?
2. Do you have uninsured/underinsured motorist coverage that matches your liability limits (or comes close)?
3. Do you have the right medical coverage (PIP or MedPay) for your state and health insurance situation?
4. Are you paying for collision/comprehensive on a car that isn’t worth much?
5. Could you comfortably pay your deductible tomorrow if you had to file a claim?
6. Are you paying for add-ons you don’t need (or already have elsewhere)?

How Much Liability Coverage Is Enough?

Liability coverage is the foundation of your auto policy because it protects you if you injure someone or damage their property. State minimums are designed to be “legal,” not necessarily “sufficient.” In a serious crash, medical bills, lost wages, and legal costs can add up quickly.

When Higher Limits Usually Make Sense

You’re more likely to be underinsured if you have assets or income that could be targeted after a major accident. Even if you don’t feel “wealthy,” things like home equity, savings, future wages, or business ownership can increase your exposure. If you’ve ever wondered what happens when someone sues you after a car accident, it’s a good reminder that the financial downside of low liability limits can be severe.

Some people with high savings prefer to carry solid liability limits while “self-insuring” for smaller losses. If that’s your mindset, this overview of self-insured car insurance explains what it can (and can’t) realistically do for you.

How to Tell If You’re Underinsured

You may be underinsured if any of the following are true:

• You carry only state minimum liability limits and have savings, a home, or steady income you need to protect.
• You don’t have uninsured/underinsured motorist coverage (or it’s much lower than your liability limits), even though uninsured driving remains common in many states.
• Your medical coverage for car crashes is thin. One accident can lead to costly treatment—see how car insurance can pay for medical bills after an accident depending on your coverages and state rules.
• You couldn’t afford a major out-of-pocket loss (like replacing your vehicle or paying a large deductible) without going into debt.
• You drive a lot, commute in heavy traffic, transport passengers often, or have teen drivers on your policy.

Another simple test: imagine you cause a crash tomorrow and your insurer pays only up to your policy limits. If the “worst reasonable day” would threaten your finances, you likely need higher limits.

How to Tell If You’re Overinsured

Overinsurance usually shows up as paying for coverages that don’t make financial sense for your situation—especially on older vehicles or duplicate protections.

Common signs you might be overinsured include paying for full coverage on a low-value car, choosing deductibles you can’t comfortably afford (which can make coverage feel “useless” in practice), or buying multiple add-ons you’ll never use.

Vehicle Coverage: Collision and Comprehensive

After liability, the next big decision is whether it makes sense to insure your own car for damage and theft.

Collision Coverage

Collision coverage helps pay to repair or replace your vehicle after a crash (regardless of fault in many cases, subject to your policy rules and deductible). It’s often required for financed or leased vehicles.

Collision is a prime area where people overpay on older cars. If your vehicle isn’t worth much, it may be reasonable to drop collision coverage on an older vehicle—especially if the premium savings are meaningful and you could replace the car if needed.

Comprehensive Coverage

Comprehensive coverage (sometimes called other-than-collision) covers many non-crash losses like theft, vandalism, hail, flood, fire, and animal-related damage. It’s often relatively affordable compared to collision, and it can be the difference between “annoying” and “financially devastating” if your car is stolen or badly damaged while parked.

People Coverage: Uninsured Motorist, PIP, and MedPay

Not every accident is straightforward—especially when the other driver doesn’t have enough insurance.

Uninsured and underinsured motorist coverage can protect you if the at-fault driver has no insurance or not enough to cover your injuries. It can also help in certain hit-and-run situations, depending on your state and policy.

For medical bills, drivers usually see one of these two options:

• Medical Payments (MedPay): Often optional, typically helps pay medical expenses for you and your passengers regardless of fault.
• Personal Injury Protection (PIP): Required in some states and may cover medical bills and additional costs like lost income, depending on the state.

If you’re underinsured, these coverages are often where the gap shows up first.

Optional Coverages Worth Reviewing

Optional add-ons can be great—if they match your lifestyle and aren’t duplicating something you already have.

Convenience Coverages

• Roadside assistance: Helpful if you want a single number to call for towing, lockouts, and jump-starts.
• Third-party roadside plans like AAA: Sometimes broader than insurer roadside, depending on your plan and needs.
• Rental reimbursement: Can be worth it if you rely on your car daily and don’t have backup transportation.

“Big Gap” Protections

• Gap insurance: Important if you owe more than your car is worth (common early in many auto loans and leases).
• Umbrella insurance: Extra liability protection above your auto policy limits (often valuable if you have assets to protect).

Vehicle-Specific Extras

• Glass coverage: May reduce or remove your out-of-pocket cost for windshield repairs/replacement depending on the policy.
• Custom parts and equipment coverage: Worth considering if you’ve added expensive aftermarket equipment.
• OEM parts coverage: Helps if you want repairs made with original manufacturer parts instead of aftermarket parts.

Coverage You Only Need in Specific Situations

If you drive for rideshare services, your personal auto policy may not fully cover you while you’re working. In that case, review rideshare insurance so you don’t discover a coverage gap after a claim.

How Often Should You Review Your Coverage?

A quick review once a year is usually enough for most drivers, plus any time one of these changes happens:

• You buy or sell a vehicle.
• You move, change your commute, or your annual mileage changes significantly.
• You add a teen driver or a high-risk driver.
• Your income/assets change (home purchase, business ownership, large savings increase).
• Your loan balance changes (especially if you may no longer need gap coverage).

FAQs About Having Enough Car Insurance

Final Word on Having Enough Car Insurance

Having “enough” insurance means you’re protected against realistic worst-case losses without paying for unnecessary extras. Start with state and lender requirements, then choose liability limits that protect your finances, add the right medical and uninsured motorist protections, and make sure collision/comprehensive still makes sense for your car’s value.

If you’re not sure, ask your insurer for a declarations page review—and compare quotes with different limit and deductible options. A small change to your limits today can prevent a very expensive surprise later.
