National Highway Traffic Safety Administration
Also known as the “NHTSA,” this U.S. governmental agency monitors, tests, and assesses vehicle and automotive equipment safety. The NHTSA provides comprehensive safety testing to all new vehicles which is reported on a vehicle’s Window Sticker. Their testing assesses safety potential under a wide range of conditions and usage to ensure a clear and comprehensive understanding of driver risk. The agency also may test vehicles and order recalls or authorized repairs when other serious safety defects are detected within construction, performance, and even the overall design.
Natural Gas Engine
A vehicle’s internal combustion engine which uses natural gas as its source of fuel rather than gasoline or other common fuel types.
The method of user interaction for a vehicular navigation system. Common interface options include a touch screen, push buttons, jog dials, and voice activation. Many navigation systems feature multiple interface options for easier and safer use while driving.
A vehicular system used to send location data from the vehicle to a global positioning satellite to determine its specific physical location and report it to the occupants in real-time on a stored or cloud-based mapping system. These devices also create driving routes using multiple calculation formulas and instruct drivers on which direction to move, which way to turn at intersections, and when they arrive at their destination.
NHTSA Campaign ID Number
Identifying number for a vehicle recall assigned by the National Highway Traffic Safety Administration. These numbers are used as reference for each recall scenario to better track, assess, and repair safety defects in recalled vehicles.
NHTSA Item Number
The number associated with each technical service bulletin provided by the National Highway Traffic Safety Administration for quick access to important safety information about a vehicle.
An exterior system which uses an infrared camera for added visibility while driving in darkness. The exterior camera is mounted somewhere on the front of a vehicle. When conditions are too dark for traditional headlights or bright settings, this camera can provide an added layer of visibility and safety while operating the vehicle.
Abbreviation for the “National Low Emission Vehicle Program,” this program provides a standard benchmark new automobile manufacturers must meet for a low emissions distinction. Outside of California, this program is enforced and operated by the Environmental Protection Agency. It is primarily used to help reduce total vehicular emissions for light-duty vehicles and trucks. An opt-in program, it has been continually grown on a state-by-state basis as a standardized method for improving emission amounts for all vehicle manufacturers.
Also known as smog, a shorthand term for the mono-nitrogen oxides nitric oxide (NO) and nitrogen dioxide (NO2). It is produced from the reaction of hydrocarbons, nitrogen, and oxygen during engine combustion. In urban areas with more drivers, smog can accumulate to dangerously high levels with observable gases and reduced visibility. It creates an extensive range of negative effects – both on the environment and on those living and working in high smog areas.
Number of Speeds
The total number of different speed levels (drive ratios) equipped within a vehicle’s transmission. Three to five speeds are generally equipped in most vehicles. However, additional speeds may be available on specialized models, sports cars, or other vehicles.
A series of vehicle devices which work to reduce the overall vibration, shakiness, and noise within the cabin. These may include engine soundproofing, electronic stability control, and other devices. The overall aim is to provide a more comfortable and less harsh ride for all vehicle occupants.
