Anti-lock Braking System (ABS) means a portion of a service brake system that automatically controls the degree of rotational wheel slip during braking by: (1) Sensing the rate of angular rotation of the wheels; (2) Transmitting signals regarding the rate of wheel angular rotation to one or more controlling devices that interpret those signals and generate responsive controlling output signals; and (3) Transmitting those controlling signals to one or more modulator devices that adjust brake actuating forces in response to those signals.

ESC is a computerized technology that improves a vehicle's stability by detecting and reducing loss of traction (skidding). When ESC detects loss of steering control, it automatically applies the brakes to help steer the vehicle in the driver's intended direction. Braking is automatically applied to wheels individually, such as the outer front wheel to counter oversteer, or the inner rear wheel to counter understeer. Some ESC systems also reduce engine power until control is regained.

A TPMS is an electronic system designed to monitor the air pressure inside the pneumatic tires on various types of vehicles. TPMS can be divided into two different types - direct and indirect. Direct TPMS employ pressure sensors on each wheel, either internal or external. The sensors physically measure the tire pressure in each tire and report it to the vehicle's instrument cluster or a corresponding monitor. Indirect TPMS does not use physical pressure sensors but measure air pressures by monitoring individual wheel rotational speeds and other signals available outside of the tire itself.

A backup camera, also known as a rearview video system, helps prevent back-over crashes and protects our most vulnerable people - children and senior citizens - by providing an image of the area behind the vehicle. A backup camera helps the driver see behind the vehicle while in reverse.

An FCW system monitors a vehicle's speed, the speed of the vehicle in front of it, and the distance between the vehicles. If the vehicles get too close due to the speed of either vehicle, the FCW system will warn the driver of the rear vehicle of an impending crash so that the driver can apply the brakes or take evasive action, such as steering, to prevent a potential crash. FCW systems provide an audible, visual, or haptic warning, or any combination thereof, to alert the driver of an FCW-equipped vehicle of a potential collision.

An LDW system monitors lane markings and alerts the driver if their vehicle drifts out of their lane without a turn signal or any control input indicating the lane departure is intentional. An audio, visual or other alert warns the driver of the unintentional lane shift so the driver can steer the vehicle back into its lane.

Engine displacement (in cubic centimeters) is the volume swept by all the pistons inside the cylinders of a reciprocating engine in a single movement from top dead center to bottom dead center.

Engine displacement (in cubic inches) is the volume swept by all the pistons inside the cylinders of a reciprocating engine in a single movement from top dead center to bottom dead center.

Engine displacement (in liters) is the volume swept by all the pistons inside the cylinders of a reciprocating engine in a single movement from top dead center to bottom dead center.

Engine configuration defines how engine cylinders are arranged. Common values are V6 for V-shaped arrangement, I4 or L4 for in-line arrangement.

Engine model is a name that a manufacturer applies to a family of engine.

This is a numerical field to store the number of cylinders in an engine. Common values for passenger cars are 4 or 6.

Fuel type defines the fuel used to power the vehicle. For vehicles that have two power sources, such as plug-in hybrid vehicle, both primary fuel type and secondary fuel type will be provided.

Body Class presents the body type based on 49 CFR 565.12(b): "Body type means the general configuration or shape of a vehicle distinguished by such characteristics as the number of doors or windows, cargo-carrying features and the roofline (e.g., sedan, fastback, hatchback)." Definitions are not provided for individual body types in the regulation.

This is a numerical field to store the number of doors on a vehicle.

Gross vehicle weight rating (GVWR) is the maximum operating weight of a vehicle including the vehicle's chassis, body, engine, engine fluids, fuel, accessories, driver, passengers and cargo, but excluding that of the trailers. Per 49 CFR 565.15, Class 1 is further broken down to Class A-D; Class 2 is further broken down to Class E-H. This field captures the lower bound of GVWR range for the vehicle.

Cab type applies to both pickup truck and other medium- and heavy-duty trucks. The cab or cabin of a truck is the inside space in a truck where the driver is seated. For pickup trucks, the cab type is categorized by the combination number of doors and number of rows for seating. For medium- and heavy-duty trucks (MDHD), the cab type is categorized by the relative location of engine and cab.

For pickup trucks, there are four cab types.

• Regular: 2 door, 1 row of seats
• Extra/Super/Quad/Double/King/Extended: 2 doors, 2 rows of seats
• Crew/Super Crew/Crew Max: 4 doors, 2 rows of seats
• Mega: 4 doors, 2 rows of seats (with a bigger cabin than crew cab type)

For medium- and heavy-duty (MDHD) trucks, there are several categories as listed below.

• Cab Beside Engine
• CAE: Cab Above Engine
• CBE: Cab Behind Engine
• COE: Cab Over Engine or Flat Nose: Driver sits on top of the front axle and engine
• LCF: Low Cab Forward
• Conventional: Driver sits behind the engine
• Non-Tilt
• Tilt

Per 49 CFR 565, Make is a name that a manufacturer applies to a group of vehicles or engines.

Per 49 CFR 565, Model means a name that a manufacturer applies to a family of vehicles of the same type, make, line, series and body type.

If the model year (MY) is supplied when the VIN is decoded, such as from a crash report or a vehicle registration record, the MY value will be the supplied MY, even if the MY decoded from the VIN differs from the supplied MY. If the MY is not supplied when the VIN is decoded, the MY value will be decoded from the 10th character in the VIN.

This data element captures the city of the manufacturing plant where the manufacturer affixes the VIN.

This data element captures the country of the manufacturing plant where the manufacturer affixes the VIN.

This data element captures the State or Province name within the Plant Country of the manufacturing plant where the manufacturer affixes the VIN.

Per 49 CFR 565, Series means a name that a manufacturer applies to a subdivision of a "line" denoting price, size or weight identification and that is used by the manufacturer for marketing purposes.

Trim levels further identify a vehicle by a particular set of special features. Higher trim levels either will add to the features of the base (entry-level model), or replace them with something else.

This field defines the type of the vehicle based on the World Manufacturer Identifier (WMI).

An internal NHTSA field to capture the body type of the vehicle.

An internal NHTSA field to capture the Make of the vehicle.

An internal NHTSA field to capture the Model of the vehicle.

Brake system type is the type of brake systems used to stop and hold the vehicle or combination of motor vehicles.

Drive type stores information about vehicle drivetrain configuration. The most common drive types for passenger cars, crossover vehicles, and pickup trucks are front-wheel drive (FWD), rear-wheel drive (RWD), all-wheel drive (AWD), and 4-wheel drive (4WD).

This field describes the type of seat belt, such as manual or automatic. Automatic seat belts automatically close over riders in a vehicle. Automatic seat belts were mainly used in some older model GM, Nissan, and Honda vehicles and are rarely seen now.

This field captures the location of curtain air bags. Curtain air bags are side air bags that protect the head.

This field captures the location of frontal air bags. Frontal air bags are generally designed to deploy in "moderate to severe" frontal or near-frontal crashes.

This field captures the location of side air bags, typically designed for three areas of added protection: chest/torso, head, or both.
