Umbrella insurance: liability protection above your auto policy

A personal umbrella policy is extra liability insurance that pays after your auto (or home) liability limits are used up, typically in amounts of $1 million or more. It does not replace your car insurance; the umbrella insurer requires you to keep minimum liability limits on every vehicle in the household, and it starts paying only above them. For drivers with assets or income to protect, it is usually the cheapest way to add a large amount of liability protection.

How an umbrella works with your auto policy

Think of coverage in layers:

1. Your auto policy pays first, up to its liability limits, for injuries and property damage you cause.
2. The umbrella pays next, up to its own limit, once the auto policy's limit for that claim is exhausted.
3. You are responsible for anything above both.

The umbrella insurer sets the floor your auto policy must meet, called the required underlying limits. They are written into the umbrella application and policy, either as split limits or as a combined single limit. If your auto limits fall below that floor, the umbrella does not drop down to fill the gap; you pay the difference yourself. That is the most common and expensive umbrella mistake.

Progressive, for example, tells shoppers on its umbrella page that umbrella buyers can choose "$1 million or more" in added liability protection, depending on the carrier.

A worked example

This example is hypothetical. Sam has auto liability limits of 250/500/100 and a $1 million umbrella that requires underlying limits of 250/500/100. He causes a crash that badly injures another driver, and a court awards $900,000.

• Auto policy pays the per-person limit: $250,000.
• Umbrella pays the remainder: $650,000.
• Sam pays: $0.

Now suppose Sam had lowered his auto limits to 100/300/100 to save money without telling anyone. The auto policy pays $100,000. The umbrella still treats the first $250,000 as the auto policy's job, so it pays only $650,000 above that line. Sam owes the $150,000 gap himself.

What an umbrella usually adds beyond auto

An umbrella covers liability from many parts of your life, not just driving. Typical umbrella policies extend to:

• Injuries to guests at your home and other premises liability.
• Liability from vehicles and watercraft listed on your underlying policies.
• Some claims your underlying policies may not cover at all, such as certain personal injury claims for libel or slander, subject to a self-insured retention you pay first.
• Legal defense costs, which many umbrellas pay in addition to the limit.

The exact list depends on the policy form. Read the coverage section, not just the limit.

What it does not cover

• Your own car or your own injuries. Like auto liability, an umbrella pays others.
• Business and for-hire driving. Rideshare, delivery and other business use are commonly excluded or limited. See using your personal car for work.
• Vehicles or drivers not on the underlying policy. If a household driver or car is not insured on an underlying policy that meets the requirement, expect a coverage problem. Check the household member rules in your policy.
• Intentional acts and contractual liability.
• Uninsured and underinsured motorist protection, unless you add it. Many umbrellas pay only liability claims against you. Some insurers offer excess UM/UIM as an option; ask, because it protects you if a minimum-limits driver injures you. See uninsured and underinsured motorist coverage explained.

Who should consider one

An umbrella deserves a quote if any of these apply:

• Your net worth, excluding protected retirement accounts, is more than your auto liability limits.
• You have a teen or newly licensed driver in the household. See adding a teen driver to your car insurance.
• You own rental property, a pool, a trampoline or a dog breed insurers flag.
• Your income is high enough that a judgment could take a meaningful share of future wages.
• You often drive other people, such as a carpool or youth sports team.

Drivers with substantial wealth sometimes buy auto and umbrella coverage together from a private-client carrier; see high-net-worth auto insurance: what private client carriers add.

How large an umbrella to buy

Umbrellas are usually sold in round amounts, starting at $1 million. A simple way to size one is to add your net worth outside protected retirement accounts to a few years of income, then round up to the next available limit. Someone with $600,000 of home equity and investments and a $150,000 salary might look at $1 million or $2 million rather than the minimum.

The size of the risk matters too. A household with two teen drivers, a long commute and a lake house has more ways to cause a large claim than a retired couple who drive rarely. Price at least two umbrella limits; the step from the first million to the second is often a small addition, because the second million is used even less often than the first.

Buying checklist

1. Get the underlying requirement in writing for auto, home and any other policies, and confirm your current limits meet it.
2. List every vehicle and driver in the household and make sure each is insured on a qualifying policy, including cars owned by adult children living at home.
3. Ask whether the umbrella pays defense costs on top of the limit and whether it has a self-insured retention for claims your underlying policies do not cover.
4. Ask about excess uninsured and underinsured motorist coverage.
5. Consider buying from the same insurer as your auto and home policies. It is not required, but it reduces the chance of mismatched limits and may earn a multi-policy discount.
6. Re-check the requirement at every auto renewal and whenever you change carriers, add a driver or buy a vehicle.

Key takeaways

• An umbrella adds liability protection, usually $1 million or more, above your auto and home limits.
• It pays only after your auto policy's limit is used up, and only above the underlying limits it requires.
• If your auto limits drop below the required underlying limits, you pay the gap yourself.
• Umbrellas do not cover your car, your injuries or most business driving; excess UM/UIM is a separate option.
• Keep every household vehicle and driver on a qualifying underlying policy.
