Short answer: After a hurricane or flood, damaged cars are sometimes cleaned up and taken out of state for sale, so a flooded car can show up far from the storm (FTC). Check for a musty smell or heavy air freshener, mud or waterlines in hidden spots, and unusual rust (NHTSA). Run the VIN through the federal National Motor Vehicle Title Information System (NMVTIS) at vehiclehistory.gov, which keeps every reported "flood" or "salvage" brand so moving a car to another state can't erase it (NMVTIS). Then have an independent mechanic inspect the car (FTC). If your own car floods, that's a comprehensive claim, not collision (NAIC).
This guide applies in all 50 states. It is based on NHTSA, Federal Trade Commission and U.S. Department of Justice (NMVTIS) guidance, plus insurance-regulator consumer guides, checked in October 2026. Title terms differ by state, so check with your state's motor vehicle agency for the brands it uses.
Why flooded cars travel
When an insurer declares a flooded car a total loss, the car gets a new title, called a "salvage" or "flood" title. It's then usually sold at a salvage auction to junkyards or rebuilders. It's legal to resell it to consumers if the damage is noted on the title, the car has been rebuilt, and it has a "rebuilt" title (NHTSA). The trouble comes when that history disappears.
The Justice Department's NMVTIS site gives an example. After Hurricane Katrina, authorities reported truckloads of flooded cars taken from Louisiana to other states, as far as the upper Midwest. There they were dried out and sold to buyers in states that don't brand flood vehicles. Buyers may not have known that saltwater made the cars' electrical systems, including air bag sensors, more likely to fail (NMVTIS).
Title terms, in plain English
| Term | What it means |
|---|---|
| Salvage title | An insurer declared the car a total loss because of a serious accident or other problems (FTC). |
| Flood title | The car was damaged by water deep enough to fill the engine compartment (FTC). |
| Rebuilt title | A salvage or flood car was rebuilt and can legally be resold, with the history noted (NHTSA). |
| Brand | A label a state puts on a title to show current or past condition, like "junk," "salvage" or "flood" (NMVTIS). |
| Title washing | Retitling a branded car in another state that doesn't check prior brands, so the new title looks clean (NMVTIS). |
States don't all use the same rules. One state might brand a damaged car "salvage" while another doesn't, because the damage doesn't reach that state's dollar threshold. Some states have no "flood" brand at all (NMVTIS). NHTSA warns buyers to beware of flood-damaged cars with clean or "lost" titles (NHTSA).
Inspection red flags
From NHTSA and the FTC (NHTSA; FTC; FTC):
- Smell. A musty odor suggests the car has been in water. A strong smell of deodorizer, air freshener or cleaning products may be covering up mildew.
- Dirt and waterlines. Look for mud, sand, silt or water stains under the seats, carpet, floor mats and dashboard, and in the trunk and glove box.
- Rust and corrosion. Check underneath for more rust than you'd expect for the car's age and location, and look around the doors.
- Carpet and upholstery. Watch for loose, stained or mismatched carpet. New carpet or upholstery in an older car is another red flag.
- Lights. Look for fogging inside the headlights and taillights.
NHTSA cautions that flood damage can affect a car's systems for years and may not show up right away (NHTSA). That's why the FTC recommends an independent mechanic's inspection. Water can slowly ruin mechanical and electrical systems and cause rust and corrosion (FTC).
Free and low-cost history checks
- NMVTIS (vehiclehistory.gov). This federal title database pulls in data from state titling agencies, auto recyclers, junk and salvage yards, and insurers. A report shows the title and brand history, the latest odometer reading, any insurer "salvage" or total-loss determination, and transfers to a recycler or salvage yard (NMVTIS). The FTC says you can get free information on a car's title, latest odometer reading and condition there. Approved providers sell fuller reports for a fee (FTC; FTC).
- The NICB database. The FTC notes that the National Insurance Crime Bureau has a free VIN check showing whether a car was flood-damaged, stolen and not recovered, or declared salvage. It only covers cars that were insured when the damage happened (FTC).
- Commercial reports. Some paid reports add accident and repair history (FTC).
- Recalls. While you have the VIN, check for open safety recalls (FTC). See our vehicle recall guide.
Know the limits. NMVTIS says a clean report is good news, but not every reporting entity sends data yet, so a search can come back falsely clean. About 87% of U.S. vehicles are in the system, with roughly 20 million salvage or total-loss records (NMVTIS). An insurer's "total loss" label also doesn't always mean a car was wrecked. A stolen car not recovered within 30 days may be labeled a total loss, then found later in good condition (NMVTIS). A history report doesn't replace a mechanic's inspection (FTC).
If you suspect fraud. Tell the NICB, report it at ReportFraud.ftc.gov, and contact your state attorney general (FTC).
If your own car flooded
1. Don't start it yet. NHTSA says to assess the car thoroughly first, because there may be damage you can't see (NHTSA).
2. Hybrids and EVs need extra care. Their batteries are highly corrosive and shouldn't sit in standing water. Flooded batteries can short and cause shocks or fires. NHTSA says don't park a damaged lithium-ion vehicle in a garage or within 50 feet of a house, another structure, another vehicle or anything combustible. Contact your dealer (NHTSA).
3. Call your insurer first. NHTSA's first recommendation for a car totaled in a hurricane is to contact your insurance company (NHTSA). Also tell the insurer about damaged equipment such as car seats or mobility equipment (NHTSA).
4. Flood is a comprehensive claim. Comprehensive pays for damage not caused by a collision, including flood, hail, windstorm, fire and theft (NAIC). If you carry only liability, flood damage to your own car isn't covered. You pay your comprehensive deductible (Texas Department of Insurance). If you have a loan, your lender likely requires comprehensive and collision (NAIC).
5. If it's totaled. The insurer pays the car's actual cash value, meaning its value minus depreciation, not the cost of a new car. You can negotiate with written quotes for similar cars. If you owe more than the car is worth, gap coverage pays the difference (Texas Department of Insurance). If you keep the car, the insurer subtracts its salvage value from the settlement (Texas Department of Insurance). See car total loss and gap insurance and total-loss car valuation rules by state.
6. Hand over the title correctly. If the insurer pays a total loss, NHTSA asks owners to make sure the title goes to the insurer with the required federal odometer disclosure, so future buyers are protected (NHTSA). If your title was lost in the storm, your state DMV can tell you how to get a copy (NHTSA).
Home flood coverage is separate. Flood damage to your house and belongings is a different policy. See our flood insurance guide.
Before you buy a car after storm season
- Ask where the car has been titled and registered, and compare that with the NMVTIS report (NMVTIS).
- Do the smell, dirt, rust, carpet and headlight checks above (NHTSA; FTC).
- Pay for an independent inspection before you buy (FTC).
- Before you sign, ask your insurance agent how a branded or rebuilt title would affect your coverage and claim value.
- Get any seller promises in writing.

Frequently asked questions
How can I tell if a used car was in a flood?
Check for a musty smell or heavy air freshener, mud or waterlines under seats, carpet and dashboard and in the trunk, unusual rust, mismatched or new carpet, and fogged headlights. Then have an independent mechanic inspect it (NHTSA; FTC; FTC).
What is title washing?
It's when a car branded salvage, flood or junk is retitled in a state that doesn't check prior brands, so the new title looks clean. NMVTIS keeps all reported brands so a move between states doesn't erase them (NMVTIS).
Is a vehicle history report from vehiclehistory.gov free?
The FTC says you can get free information on a vehicle's title, latest odometer reading and condition starting at vehiclehistory.gov. Approved providers charge for fuller reports (FTC; FTC).
Does car insurance cover flood damage?
Yes, if you carry comprehensive coverage. Comprehensive pays for non-collision damage, including flood, minus your deductible. Liability-only policies don't cover your own car (NAIC; Texas Department of Insurance).
What's the difference between a salvage title and a flood title?
The FTC explains that a salvage title means an insurer declared the car a total loss after a serious accident or other problems. A flood title means water was deep enough to fill the engine compartment (FTC).
