Does car insurance cover flood damage in Texas?

Flood is the peril that behaves differently from every other one, and the reason it confuses people is that the same word gets opposite answers on the two policies most Texans own.

On your house, flood is the famous exclusion — the thing your policy leaves out and a separate flood policy has to pick up. On your car, there is no separate flood policy to buy. Floodwater is covered under a coverage you already know by another name, if you bought it.

The Texas Department of Insurance (TDI) states the car half in one sentence: "If you have comprehensive auto coverage, you're covered for flood damage to your car."

The whole answer sits in that "if". Comprehensive is optional in Texas, and a driver carrying only what the state requires does not have it.

Here's what we'll cover: which coverage pays and whether you have it, why the answer is the opposite of the one on your house, what TDI says to do before trying to start the car, how a flooded car gets declared a total loss, what happens if you owe more than the settlement, the car that floated away, whether the claim can raise your rates, and how to avoid buying somebody else's flooded car later.

The coverage that pays is comprehensive

TDI defines the two physical-damage coverages separately, and floodwater is named in one of them:

• Collision coverage "pays to repair or replace your car after an accident."
• Comprehensive (other than collision) coverage "pays if your car is stolen or damaged by fire, flood, vandalism or something other than a collision."

TDI's storm-preparation guidance says the same thing in the language of a storm: comprehensive "will pay to repair or replace your car if it's damaged or destroyed by hail, wind, fire, or flood."

And in TDI's table of what most auto policies cover, the entry reads: "Damage to your car because of fire, hail, theft, flood, flying gravel, or hitting an animal (if you have comprehensive coverage)."

Three separate TDI pages, the same parenthesis every time. Flood damage to a car is a comprehensive claim, and comprehensive is not automatic.

Whether you have it is a two-line check

Texas requires liability coverage — the coverage that pays for the harm you cause other people. It does nothing for your own car. TDI: "There are eight basic auto insurance coverages. You can choose whether to buy the others."

So comprehensive is a coverage you either bought or didn't, with two common exceptions worth knowing:

• If you're still paying for the car, you almost certainly have it. TDI: "If you still owe money on your car, your lender will require you to have collision and comprehensive coverage."
• If you own the car outright, nothing forces the issue, and dropping comprehensive on an older car is a decision plenty of drivers make deliberately. The trade-off is that a flood is exactly the loss it was protecting against.

TDI points at where to check: "You can find coverage information on your policy's declaration page. If you don't have your policy, contact your agent or insurer." If you can't find either, TDI's Help Line at 800-252-3439 can "get a contact number for your insurance company."

One more line to read while you're on that page: comprehensive claims carry a deductible. TDI: "You must pay a deductible for collision, comprehensive, and uninsured/underinsured motorist claims. A deductible is the amount of a claim that you must pay yourself." Our guide on how home insurance deductibles work in Texas covers the mechanism generally; on your car it's the figure printed beside the comprehensive line.

Why your house answers the opposite way

This is the part worth carrying around, because it's the reason so many households discover the gap on the wrong day.

TDI on the home side: "Most home policies don't cover damage caused by floods." The fix is a separate policy — from the National Flood Insurance Program or from a private company — and TDI adds a timing warning that matters more than any other sentence in this article: "Most flood policies have a 30-day waiting period before kicking in so don't wait for an approaching storm before deciding to buy coverage."

TDI also disposes of the assumption that flood is a coastal or floodplain problem: "floods can happen anywhere. More than half of homes flooded by Hurricane Harvey were outside of designated flood zones."

Put the two halves side by side and the shape is clear:

A household can therefore be fully covered for a flooded car and completely uncovered for the flooded house it was parked at. Our guide on flood insurance in Texas covers the home side, and what home insurance doesn't cover in Texas sets flood among the other standard exclusions.

Before you do anything else: don't start it

The single most expensive mistake after a flooded car is a mechanical one, and TDI is direct about it.

On drying it out: "This task is best left to a professional if water got in your car. If it's not dried out correctly, your car will be at risk of mold, electrical issues, and other problems."

On the engine: "Experts recommend that you have a mechanic look at a flooded car before trying to start it to avoid more damage."

Two things follow from that. The obvious one is that turning the key to "see if it's alright" can convert a repairable car into a wrecked one. The less obvious one is that the damage you're most likely to be arguing about later — mould and electrics — is the damage that develops after the water has gone, which is a reason to document the car wet.

Filing the claim

TDI's instructions are short and in order:

• "Call your insurance agent or company as soon as possible. Your policy should have a number to call to report a claim."
• "Take photos of the damage and, if possible, of your car submerged."
• Expect the adjuster to take time. TDI: "It might take time for your company to send an adjuster out to look at the damages. Texas law requires companies to pay claims timely, but those deadlines can be extended for disasters."

That last sentence is TDI's, and it's the honest expectation-setter after a widespread event: the deadlines exist, and they stretch when a whole region files at once. Our guide on how to file a car insurance claim in Texas covers the general process, and how to file a hail or storm damage claim in Texas covers the storm version on the property side.

If you need paperwork you lost in the flood, TDI notes that a replacement title comes from the Texas Department of Motor Vehicles, "by mail or in person."

Will it be totalled?

Often, and for a reason that has changed in the last decade or so.

TDI describes the test: "The insurance company will look at your car's actual cash value vs. the cost of repairs. If fixing your car will cost more than what it's worth, your insurance company will consider it totaled."

Then it retires the rule of thumb most people are working from:

"There was an old rule of thumb that once water reached the dashboard, the car was likely to be a total loss. But today's cars have more electronics and can cost more to repair so a car may be totaled even if water didn't get into the engine."

That's the flood-specific finding worth knowing before you argue with anyone: the waterline is no longer the test. A modern car carries control modules, wiring harnesses and sensors low in the body and under the seats, and water that never reached the dashboard can still total it on repair cost alone.

If you'd rather keep the car, TDI sets out what that means: "the insurance company will subtract the car's salvage value from the amount it was planning to pay you. The car also may be issued a salvage title. After it's repaired, you'll need to get a new title from the Texas Department of Motor Vehicles before you can drive it." And the consequence to weigh: "a vehicle that had a salvage title could be harder to sell or insure in the future."

If you think the settlement is too low

TDI treats the car's value as negotiable and tells you what to bring:

"If you think your car is worth more than what the insurance company decided, you can try to negotiate. Be prepared to show what the car would sell for in your area. Get quotes from used car dealers. View prices online and look for local ads for similar vehicles. Document any special features or custom parts on your car."

Two practical notes on that. Local comparables carry more weight than national averages, because that is the market TDI points you to. And custom parts and options are the part nobody documents until it's too late — photos of the car as it was are worth taking now, flood or no flood.

If you owe more than the settlement

A flood total loss is where negative equity turns into a real bill, and TDI states the position plainly:

"If you have a gap policy, it will pay the difference between what you owe and the settlement amount. If you don't have a gap policy, you'll be responsible for paying off the remainder of the loan."

There is no softer version of that sentence. A totalled car pays out its value, not your loan balance, and the shortfall belongs to whoever signed the loan. TDI's separate guidance on gap products adds one thing worth knowing in advance: "Gap products you get from a car dealer or bank might not be insurance. TDI can't help if you have a problem with these."

What if the car floated away?

It happens in flash floods, and TDI has a specific answer rather than a general one: "Contact the police department's unclaimed autos department to see if your car has been recovered."

Report it to your insurer at the same time. A car that has been moved by water and not yet found is a claim you can open now rather than after it turns up.

Can a flood claim raise your rates?

Different question from whether it's covered, and one where the home and auto rules are not the same — so be careful importing what you know from your house.

TDI's general position: "Home and auto insurance companies can raise your premium for filing most types of claims."

TDI then lists what home and auto companies can't charge you more for:

"Claims you file that the company didn't pay. This includes claims the insurance company denied because your policy doesn't cover the damage."

"Calling your company or agent to ask questions about your policy or the claims filing process."

And separately, what home companies can't charge more for: "Claims for damage from natural causes, including weather."

Read that boundary carefully. The weather-claim protection appears in TDI's home list, not its auto list, so don't assume a weather event gets the same treatment on the car side. What is clearly safe on both is the phone call: asking your agent whether you have comprehensive is not a claim, and it costs nothing to ask before the forecast turns.

Worth knowing too: claims records travel. TDI notes that most companies use the Comprehensive Loss Underwriting Exchange (CLUE), and "because most companies use CLUE, they can learn about home or auto claims you've filed, even if the claim was with another insurance company." You can get a free copy of your report each year by calling 866-312-8076. Our guide on do car insurance claims follow you in Texas covers how that history is used.

Buying a used car after a flood season

The other side of a Texas flood is the resale market a few months later, and TDI's warning is blunt: "Once an engine gets waterlogged, it's almost impossible to ever make it right. Unfortunately, some unscrupulous sellers will buy these salvage cars at auction and resell them to unsuspecting buyers across the state and nation."

TDI's checks, starting with the ones that cost nothing:

• Look for the physical signs. "Stains, mildew, rust, and discoloration are signs of water damage. Look for dirt or debris under the floor mats, carpet, or where the spare tire is located." And the counter-signal most people miss: "Mold or mildew will give off a musty odor; if you notice a strong smell of cleaner or disinfectant, it could be an attempt to cover up those odors."
• Check the title. TDI: "When a vehicle is declared a total loss, the title must be changed to a salvage or non-repairable title. You can ask to see the title, and a vehicle history report will list the status of the title."
• Check the VIN. TDI points to the National Insurance Crime Bureau's free VINCheck service, where the database "will show if that vehicle has been stolen or listed as a total loss."
• Have a mechanic look it over. TDI: "Flood damage isn't always obvious."
• Apply the same checks to boats and RVs, which TDI notes also reappear on the resale market after floodwaters.

That matters on the insurance side as well as the buying side, because of TDI's own warning above: a vehicle that carried a salvage title can be harder to insure later.

What to do with this

• Check the declarations page for a comprehensive line. TDI: "If you have comprehensive auto coverage, you're covered for flood damage to your car." No line, no flood coverage.
• Don't reason from your home policy. TDI: "Most home policies don't cover damage caused by floods" — the car answer is the opposite of the house answer.
• If you want flood coverage on the house, don't wait for a storm. TDI: most flood policies have a 30-day waiting period.
• Don't start a flooded car. TDI: have a mechanic look at it first "to avoid more damage."
• Photograph it wet, submerged if you can — TDI names this as a claim step, and mould and electrical damage show up later.
• Forget the dashboard rule. TDI: modern cars "may be totaled even if water didn't get into the engine."
• Bring local comparables if you dispute the value. TDI: quotes from used-car dealers, local ads, and documentation of custom parts.
• Know whether you have gap cover before the loss, and whether the product came from a dealer or bank rather than an insurer.
• If the car floated away, call the police department's unclaimed autos department as well as your insurer.
• Ask questions freely. TDI says companies can't charge you more for "Calling your company or agent to ask questions about your policy or the claims filing process."

Key facts

• Flood damage to a car is a comprehensive claim. TDI: comprehensive "pays if your car is stolen or damaged by fire, flood, vandalism or something other than a collision."
• Comprehensive is optional. TDI: "There are eight basic auto insurance coverages. You can choose whether to buy the others." But "if you still owe money on your car, your lender will require you to have collision and comprehensive coverage."
• A deductible applies. TDI names collision, comprehensive and uninsured/underinsured motorist as the coverages you must pay a deductible for.
• Your home policy is the opposite. TDI: "Most home policies don't cover damage caused by floods," and most flood policies "have a 30-day waiting period."
• Flood is not only a flood-zone problem. TDI: "More than half of homes flooded by Hurricane Harvey were outside of designated flood zones."
• Don't try to start it. TDI: "Experts recommend that you have a mechanic look at a flooded car before trying to start it to avoid more damage."
• The total-loss test is value against repair cost. TDI: "If fixing your car will cost more than what it's worth, your insurance company will consider it totaled."
• The waterline rule is obsolete. TDI: today's cars "may be totaled even if water didn't get into the engine."
• Gap decides who pays the loan shortfall. TDI: without a gap policy, "you'll be responsible for paying off the remainder of the loan."
• The settlement figure is negotiable. TDI: "you can try to negotiate. Be prepared to show what the car would sell for in your area."
• Weather-claim rate protection is stated for home, not auto. TDI lists it under what home companies can't charge more for.
• Flood-damaged cars come back to market. TDI: check the title, run the VIN through NICB's VINCheck, and have a mechanic inspect it.

Take the next step

Everything above reduces to one line on one page. Flood damage to your car is covered if — and only if — comprehensive is on the policy, and that is a line item you can read in about ten seconds.

So the useful sequence is short. Open the declarations page and look for comprehensive. If it's there, note the deductible beside it, because that's your share of any flood claim. If it isn't there, the question is no longer what your policy would pay after a flood — it's whether you want that coverage before the next one, which is a conversation with your agent rather than a claim.

Then do the same check on the house, where the answer runs the other way and the 30-day waiting period means the decision can't be made late. Our guide on does home insurance cover fence damage in Texas works through the same covered-and-not-covered boundary on the property side.
