Vehicle History Glossary
Plain-English definitions for 97+ VIN, title, and vehicle-history terms — from "actual cash value" to "rebuilt title".
Every vehicle history report is packed with industry jargon — title brands, odometer codes, auction shorthand, and DMV acronyms — that can be hard to parse when thousands of dollars are on the line. This glossary covers the most common terms you’ll encounter when checking a VIN, reviewing a title history, or shopping for a used car.
Jump to any letter below, or browse the full A–Z list. Each entry is written in plain English and updated to reflect current U.S. title, inspection, and odometer disclosure rules.
- Abandoned
- An abandoned vehicle is any registered car, truck, trailer, boat, or similar transport left on public or private property for a period defined by state law without the owner's consent or retrieval. A vehicle may be labeled abandoned after being lost, stolen, unclaimed, or simply parked indefinitely, and is typically subject to removal and auction under state abandonment statutes.
- Accidents
- Also called a motor vehicle collision, an accident occurs when a vehicle strikes another vehicle, a stationary object such as a building, pole, tree, or parked car, or a moving object such as a pedestrian, cyclist, or animal. Accident events appear on a vehicle history report whenever they are reported to police, insurance carriers, or repair facilities.
- Actual Cash Value
- The estimated retail value of a vehicle at the moment it was submitted to auction by the seller, reflecting its worth before any reported damage occurred. Auctions list Actual Cash Value (ACV) for informational purposes only and make no guarantee of accuracy, so buyers should treat it as a reference point rather than a binding appraisal.
- Airbag Deployment
- A record that one or more airbags in the vehicle were triggered during a collision. Airbags deploy when crash sensors detect an impact above a preset threshold, and any deployed airbag must be replaced by a qualified technician. An airbag deployment event on a vehicle history report usually signals a prior collision of at least moderate severity.
- Assembled
- A vehicle constructed from new or used parts by a party other than a recognized original equipment manufacturer. Kit cars, hot rods, and rebuilt classics fall into this category and typically receive an "Assembled" brand on their title.
- Assignment
- The legal transfer of ownership rights, claims, and interests in a vehicle from one party to another, formalized by completing and signing the assignment section on the back of a certificate of title.
- Auto Auction
- A sales channel in which vehicles are offered to the highest bidder. Insurance, salvage, and dealer-only auctions process millions of vehicles each year, and the auction record is often the first time a damaged vehicle's condition is publicly documented on a history report.
- Body Style
- The manufacturer's classification of the vehicle's overall configuration — sedan, coupe, SUV, pickup, hatchback, convertible, wagon, or minivan. Body style is encoded in the VIN and is used for insurance, registration, and valuation.
- Bonded Title
- Also known as a Certificate of Title Surety Bond, a bonded title is issued when the legal owner cannot produce original ownership documents. The owner posts a surety bond — obtained through an insurance or bonding agent — guaranteeing their claim of ownership for a defined period, typically three years. If no one successfully challenges the bond during that period, the owner gains full legal and financial rights over the vehicle.
- Bond Released
- The return of a monetary bond previously required by a government agency once the underlying ownership claim has cleared, confirming the owner's rights to the vehicle without further restriction.
- Branded as Lemon
- A permanent title brand applied when a new vehicle has been repurchased by the manufacturer because a recurring defect could not be repaired under warranty within a reasonable number of attempts. Lemon law buyback rules vary by state, generally apply only to new vehicles still under the original manufacturer warranty, and protect consumers from repeatedly paying to fix the same unresolved defect.
- Brands
- Permanent notations applied by a state DMV to a vehicle's title, registration, or permit that signal a significant change in its condition or status. Common brands include salvage, junk, flood, fire, hail, totaled, stolen, scrapped, rebuilt, and "exceeds mechanical limits." A branded title stays with the vehicle for life and typically reduces resale value.
- Broken Odometer
- A designation indicating the odometer has failed and can no longer record traveled distance accurately. A broken odometer must be repaired or replaced, and the event should be documented so that future owners understand why the displayed mileage may not reflect true mileage.
- Certified Pre-Owned Vehicle
- A used vehicle that has passed a manufacturer-authorized multi-point inspection, met age and mileage limits, and had any needed repairs completed. Factory Certified Pre-Owned (CPO) programs typically bundle an extended warranty, roadside assistance, and a detailed inspection report, offering added confidence beyond a standard used-car purchase.
- Class
- A grouping of vehicles with similar size, purpose, or specifications across multiple manufacturers — such as compact, mid-size, full-size, luxury, or heavy-duty — used for comparisons, fuel economy reporting, and insurance rating.
- Clear Title
- A title that shows no brands, liens, or outstanding financial claims against the vehicle. A clear title is the strongest form of ownership documentation and indicates the vehicle has not been declared a total loss or otherwise rebranded.
- Color
- A plain-language description of the vehicle's exterior color — black, white, silver, red, and similar — used on titles and history reports. This is not the manufacturer's marketing name for the paint, but a general descriptive label.
- Commercial
- A registration classification indicating the vehicle is used to transport goods or passengers for business purposes, such as delivery vans, rideshare vehicles, and freight trucks.
- Corrected Title
- A replacement title issued when information on a prior title must be amended. Rules vary by state, but corrected titles are commonly issued to add or remove an owner after marriage or divorce, or to correct a misspelled name, wrong address, or incorrect odometer reading.
- Cylinders
- The number of combustion chambers in a vehicle's engine — typically 3, 4, 6, 8, 10, or 12. Cylinder count is encoded in the VIN and is a standard specification on titles, registrations, and service records.
- DMV
- Short for Department of Motor Vehicles, the state agency that administers vehicle titles, registrations, license plates, and driver licensing. DMVs are the primary source of title history data reported to NMVTIS.
- Damage Severity
- A classification of how serious the reported damage to a vehicle is. Minor damage covers cosmetic issues like scratches, dents, and minor bumper scuffs that do not affect safety. Moderate damage involves multiple components and may or may not affect drivability. Severe damage affects structural or critical safety systems and usually precedes a total loss determination.
- Date Reported
- The date on which a specific title, insurance, service, auction, or inspection event was recorded with the reporting source.
- Dismantled Title
- A title issued when a vehicle has been damaged so severely that the cost of repair exceeds its value and it may only be used for parts or scrap metal. Unlike a salvage title, a dismantled vehicle cannot legally return to the road.
- Drive
- The drivetrain configuration of the vehicle — front-wheel drive, rear-wheel drive, all-wheel drive, or four-wheel drive — as encoded by the manufacturer and reflected in the VIN.
- Duplicate Title
- A replacement title issued by a state DMV after the original has been lost, stolen, destroyed, or mutilated. A duplicate is simply a new copy of the same title and does not indicate a change of ownership.
- Emission / Safety Inspection
- A state-mandated test performed at an authorized inspection station to measure tailpipe emissions and verify that the vehicle meets environmental and mechanical safety standards. Inspection results often include a recorded odometer reading and contribute to a vehicle's history timeline.
- Engine
- The motor specification of the vehicle, typically including displacement, cylinder count, and fuel type, as identified by the VIN.
- Exceeds Mechanical Limits
- A notation applied when an odometer has rolled past its maximum value — 99,999 on a five-digit odometer or 999,999 on a six-digit odometer — and can no longer display accurate mileage. Titles issued for such vehicles usually carry this brand.
- Exempt
- A vehicle that is not subject to standard odometer disclosure laws, typically due to its age, class, or gross vehicle weight.
- Exempt from Odometer Disclosure
- Under federal law, odometer disclosure is required only for vehicles under a defined age (historically ten years, now expanded to twenty under updated NHTSA rules). Older vehicles are exempt, so a written odometer statement is not required when ownership changes hands.
- Failed Emissions Inspection
- An inspection outcome indicating the vehicle's tailpipe emissions exceeded state-allowed limits. Causes range from a faulty oxygen sensor or catalytic converter to missing or modified emissions components, and repeat failures often point to deeper engine problems.
- Failed Safety Inspection
- An inspection outcome indicating the vehicle did not meet minimum state safety requirements for items such as brakes, tires, lights, steering, or suspension.
- Fire Brand
- A title brand applied to a vehicle damaged by fire. In many states, a fire brand is issued when the cost of repairing the fire damage exceeds the vehicle's market value.
- First Owner
- The first individual or entity to receive a title from a state DMV as the owner of the vehicle after it left the dealer or manufacturer.
- Fleet Vehicle
- A vehicle owned or leased by a company, government body, or other organization rather than a private individual. Rental car companies, taxi services, delivery fleets, and corporate pools are common fleet operators, and fleet vehicles often carry higher mileage and more documented service history than privately owned cars.
- Flood Damage
- A designation indicating the vehicle has been damaged by flooding or exposure to standing water. Flood-damaged vehicles often suffer long-term electrical and mechanical issues even after visible repairs, making them one of the highest-risk purchases on the used market.
- Fuel
- The type of fuel the vehicle's engine is designed to use — gasoline, diesel, electric, hybrid, flex-fuel, or compressed natural gas — as encoded in the VIN.
- Government Use
- An indication that the vehicle was previously operated by a federal government agency.
- Grey Market Vehicle
- A vehicle manufactured for sale outside the United States and imported without meeting U.S. federal safety and emissions standards. Grey market vehicles can be difficult to register, insure, and service domestically.
- Hail Brand
- A title brand applied to a vehicle damaged by hail. It is typically issued when the cost of repairing the hail damage is greater than the vehicle's market value.
- High-Speed Crash Test Vehicle
- A vehicle that was subjected to a high-speed crash test by a manufacturer or testing agency and may exhibit structural or mechanical damage as a result of that test.
- Independent Inspection
- An inspection carried out by a qualified third party unrelated to the state DMV — commonly commissioned by buyers before purchasing a used vehicle to confirm condition and mileage.
- Inspections
- State-mandated periodic safety or emissions checks. Some states inspect annually, others biennially, and most record an odometer reading at each inspection, creating a mileage timeline that helps detect odometer rollback.
- Insurance Records
- Reports from insurance companies covering claims, accidents, theft events, and fault determinations. Insurance records are a key source for vehicle history data, especially for total-loss and salvage events.
- Junk Title
- A title issued to a vehicle that has been damaged beyond approximately 75 percent of its pre-damage value. Junk-titled vehicles cannot legally return to the road and are restricted to parts or scrap. Some states treat junk and salvage titles interchangeably.
- Lease
- A financing arrangement in which a leasing company buys a vehicle from a dealer and rents it to a driver for a fixed term — commonly 24, 36, or 48 months — in exchange for monthly payments. Leasing companies may be manufacturer captive finance arms or independent firms, and leased vehicles typically re-enter the used market at the end of the lease.
- Major Damage Incident
- An event in which an independent source reported that the vehicle sustained significant damage, such as a collision, flood, fire, or theft recovery.
- Make
- The brand name of the vehicle's manufacturer — Ford, Toyota, BMW, Honda, Chevrolet, and so on.
- Manufacturer Buyback
- A situation in which the vehicle manufacturer repurchases a vehicle from its owner, typically because the vehicle has repeatedly required warranty repairs for the same unresolved defect. Buyback vehicles are often rebranded under state lemon laws.
- Manufacturer Recall
- A notice issued by the manufacturer when a defect, safety risk, or failure to meet federal safety standards is identified in a specific group of vehicles. Recall repairs are performed free of charge at authorized dealerships, and owners are notified by mail. Checking open recalls by VIN is an essential step before buying any used vehicle.
- Mileage Discrepancy
- A situation in which reported odometer readings are inconsistent with earlier records, suggesting the odometer may have been tampered with, rolled back, or replaced without proper disclosure.
- Model
- The specific nameplate used by a manufacturer to identify a vehicle within its lineup — for example, Camry, F-150, Civic, or Silverado.
- Municipal Use
- An indication that a city, county, state, or federal government agency previously operated the vehicle.
- NHTSA Crash Test Vehicle
- A vehicle that was used by the National Highway Traffic Safety Administration for crash testing to evaluate occupant protection and assign federal safety ratings.
- NMVTIS
- The National Motor Vehicle Title Information System, a federal database administered by the U.S. Department of Justice that consolidates title, brand, total-loss, and salvage data from state DMVs, insurance carriers, and junk/salvage operators. NMVTIS is the authoritative source for title brand information in the United States.
- Not Actual Miles
- A designation applied when the odometer reading does not reflect the vehicle's true mileage, whether due to tampering, replacement, or mechanical failure.
- Odometer Codes
- Standard indicators describing the reliability of an odometer reading. "Actual" means the reading is believed to be true. "Exceeds Mechanical Limits" means the odometer has rolled over and the true mileage can no longer be determined. "Exempt" means federal law does not require a reading for this vehicle. "Not Actual" means the reading is known to be incorrect or cannot be verified.
- Odometer Problem
- A general indication that the odometer has a known issue, including a broken odometer, a mileage discrepancy, an exceeded mechanical limit, or a not-actual-miles designation.
- Odometer Rollback
- The illegal act of tampering with an odometer to display a lower mileage figure than the vehicle has actually traveled. Rollback is detected when a later reading is lower than an earlier recorded one, and it is a federal crime under the Truth in Mileage Act.
- Odometer Rollover
- The point at which an odometer's display reaches its maximum value and returns to zero — 100,000 miles on a five-digit odometer or 1,000,000 miles on a six-digit odometer. Rollover is a normal mechanical event for high-mileage vehicles, not a tampering event.
- Open Recall
- A manufacturer recall that has been issued but not yet completed on a specific vehicle. Open recalls remain outstanding until the repair is performed and documented, and they can pose serious safety risks if ignored.
- Ownership History
- A reconstructed timeline of the individuals or businesses that have owned a vehicle. Because not every title transaction represents a true transfer of ownership, history reports apply proprietary analysis to title events to estimate owner count for U.S.-titled vehicles built after 1992.
- Passed Emission Inspection
- An inspection outcome confirming the vehicle met the state's tailpipe emission standards on the reported date.
- Passed Safety Inspection
- An inspection outcome confirming the vehicle met the state's minimum safety standards on the reported date.
- Personal
- A registration classification indicating the owner uses the vehicle for personal, non-commercial purposes.
- Primary & Secondary Damage
- Labels used at auctions to identify the main location and a secondary location of reported damage on a vehicle. These descriptions are limited to what the seller reported and may not capture every area affected, so auction houses disclaim their accuracy and completeness.
- Prior Police
- An indication that the vehicle was previously used by a law enforcement agency. Former police vehicles often show heavier wear from extended idling, high-speed driving, and aggressive use.
- Prior Taxi
- An indication that the vehicle was previously operated as a taxi. Taxi-use vehicles accumulate mileage rapidly and may have wear beyond what the odometer alone reveals.
- Rebodied Vehicle
- A vehicle that has been reassembled using a replacement body or a new major body component, often as part of a classic-car restoration. A rebodied vehicle is not automatically salvage or scrap, but the reconstruction should always be disclosed to future buyers.
- Rebuilt / Reconstructed Title
- A title issued after a previously salvaged vehicle has been repaired, reinspected, and certified safe for road use. A rebuilt title permanently replaces the original title and generally reduces resale value, even after successful repairs.
- Recall
- A formal notice from a vehicle manufacturer or the National Highway Traffic Safety Administration (NHTSA) identifying a defect that affects safety or compliance with federal standards. Manufacturers must repair recalled defects free of charge regardless of which party issued the recall.
- Reconditioned
- A vehicle that has undergone cosmetic and mechanical repairs to restore it closer to its original condition, typically performed by a dealer or refurbishing service before resale.
- Recovered Theft
- A designation indicating a previously stolen vehicle has been located and returned to its legal owner or insurer.
- Registration / Renewal
- A state DMV event confirming that a vehicle's registration has been newly issued or renewed, allowing the vehicle to be legally operated on public roads.
- Remanufactured
- A comprehensive rebuild in which the vehicle or a major component — engine, transmission, axles, frame, or brakes — is stripped down, worn parts are replaced with parts that meet original manufacturer specifications, and the unit is reassembled. Remanufactured components must be clearly disclosed and typically carry warranties comparable to new parts.
- Rental
- A registration classification indicating the vehicle was operated as part of a rental fleet before entering the used market.
- Repair Cost
- The seller's estimated cost to repair a damaged vehicle, reported to an auction at the time of sale. The figure is informational only, may differ significantly from real-world repair estimates, and is disclaimed by the auction.
- Replaced Odometer
- A notation indicating the original odometer was removed and a new one installed, usually because the original had failed. Replacement odometers start at zero, so either the previous mileage must be transferred by a qualified speedometer shop or the replacement must be permanently disclosed on the title.
- Repossession
- The process by which a lender takes legal ownership of a vehicle after the borrower has defaulted on the loan. Repossessed vehicles often re-enter the market through dealer or insurance auctions.
- Safety Inspection
- A state-mandated mechanical check covering tires, brakes, steering, suspension, lights, and other critical systems to confirm a vehicle is safe to operate.
- Salvage Title
- A title brand applied to a vehicle that has been damaged to the point where the cost of repair exceeds roughly 75 percent of its pre-damage value, or declared a total loss by an insurer. Salvage-titled vehicles can be repaired and rebranded as "rebuilt," but they never regain clear-title status and are typically ineligible for standard financing.
- Scrapped Brand
- A designation indicating the vehicle has been marked for parts or scrap only and cannot legally return to the road.
- State Government
- An indication that the vehicle was previously operated by a state government agency.
- Stolen Vehicle
- A vehicle that has been reported missing to a state DMV or insurance company and not yet recovered. Before buying any used car, verify theft status with the National Insurance Crime Bureau (NICB) by VIN — purchasing a stolen vehicle, even unknowingly, can result in loss of both the vehicle and the purchase price.
- Suspect Miles
- A designation applied when state officials suspect the odometer may have been tampered with but cannot definitively confirm a rollback.
- Theft Insurance Claim
- An insurance claim filed by the owner after the vehicle was reported stolen.
- Theft Records
- Reports indicating the vehicle was stolen from its legitimate owner. Theft data may come from state DMVs, law enforcement agencies, or insurance carriers.
- Title History Information
- A chronological record of every title-related event — issuance, transfer, rebranding, and similar actions — associated with a specific vehicle. The title is the legal proof of ownership and can be reassigned as the vehicle changes hands.
- Title Type
- The specific category of ownership document attached to a vehicle at a given time — clear, salvage, rebuilt, junk, bonded, and so on. Each type grants specific rights and imposes certain restrictions, and reflects only the status recorded at that moment rather than the vehicle's full history.
- Totaled
- A determination that the cost of repairing a vehicle exceeds its pre-damage value, usually made by an insurance company after an accident or theft. Standards for total loss vary between insurers and by state, and a totaled vehicle may or may not receive a branded title depending on how the insurer's threshold compares to state DMV rules.
- Unknown Odometer Reading
- A designation applied when an odometer reading could not be obtained or verified at the time a record was created.
- Vehicle Age
- The number of years between the vehicle's model year and the current calendar year. Vehicle age is commonly used to assess depreciation, inspection requirements, and odometer disclosure rules.
- Vehicle Identification Number (VIN)
- A unique 17-character alphanumeric code assigned to every motor vehicle manufactured since 1981. The VIN encodes the manufacturer, country of origin, model, body style, engine, model year, assembly plant, and serial number, and is the single most important identifier used to pull a vehicle history report.
- Vehicle Service Performed
- A record indicating the vehicle underwent maintenance or repair, often accompanied by a corresponding mileage reading that contributes to the ownership and service timeline.
- Water Damage
- Damage caused by excessive exposure to water or flooding. Water damage can corrode electrical systems, wiring harnesses, and mechanical components long after the vehicle appears dry, and claims for water damage are typically filed with the owner's insurance company.
- Year
- The manufacturer-designated model year of the vehicle, which may differ from the calendar year in which the vehicle was actually built.
