The Federal Motor Vehicle Safety Standards (FMVSS) are U.S. federal vehicle regulations specifying design, construction, performance, and durability requirements for motor vehicles and regulated automobile safety-related components, systems, and design features. They are the U.S. counterpart to the UN Regulations developed by the World Forum for Harmonization of Vehicle Regulations and recognized to varying degree by most countries except the United States. Canada has a system of analogous rules called the Canada Motor Vehicle Safety Standards (CMVSS), which overlap substantially but not completely in content and structure with the FMVSS. The FMVSS/CMVSS requirements differ significantly from the international UN requirements, so private import of foreign vehicles not originally manufactured to North American specifications is difficult or impossible.
FMVSS are currently codified in Title 49 of the Code of Federal Regulations, Part 571, Subpart B ( 49 CFR 571 ), with each FMVSS standard as a section of Part 571, e.g., FMVSS Standard No. 101 is 49 CFR 571.101 . FMVSS are developed and enforced by the National Highway Traffic Safety Administration (NHTSA) pursuant to statutory authorization in the form of the National Traffic and Motor Vehicle Safety Act of 1966, which is now codified at 49 U.S.C. ch. 301.
FMVSS are divided into three categories: crash avoidance (100-series), crashworthiness (200-series), and post-crash survivability (300-series). The first regulation, FMVSS No. 209, was adopted on 1 March 1967 and remains in force to date though its requirements have been periodically updated and made more stringent. It stipulates the requirements for seat belts in roadgoing vehicles.

Aside from the FMVSS in Part 571, there are numerous federal regulations pertaining to motor vehicles under Title 49, including:
Automotive safety is the study and practice of automotive design, construction, equipment and regulation to minimize the occurrence and consequences of traffic collisions involving motor vehicles. Road traffic safety more broadly includes roadway design.
A bumper is a structure attached to or integrated with the front and rear ends of a motor vehicle, to absorb impact in a minor collision, ideally minimizing repair costs. Stiff metal bumpers appeared on automobiles as early as 1904 that had a mainly ornamental function. Numerous developments, improvements in materials and technologies, as well as greater focus on functionality for protecting vehicle components and improving safety have changed bumpers over the years. Bumpers ideally minimize height mismatches between vehicles and protect pedestrians from injury. Regulatory measures have been enacted to reduce vehicle repair costs and, more recently, impact on pedestrians.
A Neighborhood Electric Vehicle (NEV) is a U.S. category for battery electric vehicles that are usually built to have a top speed of 25 miles per hour (40 km/h), and have a maximum loaded weight of 3,000 lb (1,400 kg). Depending on the particular laws of the state, they are legally limited to roads with posted speed limits of 35 miles per hour (56 km/h) or less. NEVs fall under the United States Department of Transportation classification for low-speed vehicles. The non-electric version of the neighborhood electric vehicle is the motorized quadricycle.
In the United States and Canada, low-speed vehicle (LSV) regulations allow relaxed design and registration laws for four-wheel vehicles that have a maximum capable speed of about 25 mph (40 km/h). Several other countries have similar regulations.
The National Highway Traffic Safety Administration is an agency of the U.S. federal government, part of the Department of Transportation, focused on transportation safety in the United States.
Brake fluid is a type of hydraulic fluid used in hydraulic brake and hydraulic clutch applications in automobiles, motorcycles, light trucks, and some bicycles. It is used to transfer force into pressure, and to amplify braking force. It works because liquids are not appreciably compressible.
Federal Motor Vehicle Safety Standard 108 regulates all automotive lighting, signalling and reflective devices in the United States. Like all other Federal Motor Vehicle Safety Standards, FMVSS 108 is administered by the United States Department of Transportation's National Highway Traffic Safety Administration.
The World Forum for Harmonization of Vehicle Regulations is a working party (WP.29) of the Inland Transport Committee (ITC) of the United Nations Economic Commission for Europe (UNECE). Its responsibility is to manage the multilateral Agreements signed in 1958, 1997 and 1998 concerning the technical prescriptions for the construction, approval of wheeled vehicles as well as their Periodic Technical Inspection and, to operate within the framework of these three Agreements to develop and amend UN Regulations, UN Global Technical Regulations and UN Rules, kind of vehicle regulation.
A tell-tale, sometimes called an idiot light or warning light, is an indicator of malfunction or operation of a system, indicated by a binary (on/off) illuminated light, symbol or text legend.
A tire-pressure monitoring system (TPMS) monitors the air pressure inside the pneumatic tires on vehicles. A TPMS reports real-time tire-pressure information to the driver, using either a gauge, a pictogram display, or a simple low-pressure warning light. TPMS can be divided into two different types – direct (dTPMS) and indirect (iTPMS).
The following outline is provided as an overview of and topical guide to automobiles:
Vehicle regulations are requirements that automobiles must satisfy in order to be approved for sale or use in a particular country or region. They are usually mandated by legislation, and administered by a government body. The regulations concern aspects such as lighting, controls, crashworthiness, environment protection and theft protection, and might include safety belts or automated features.
Government regulation in the automotive industry directly affects the way cars look, how their components are designed, the safety features that are included, and the overall performance of any given vehicle. As a result, these regulations also have a significant effect on the automotive business by generally increasing production costs while also placing limitations on how cars are sold and marketed. Automotive regulations are designed to benefit the consumer and protect the environment, and automakers can face stiff fines and other penalties if they are not followed.
Title 40 is a part of the United States Code of Federal Regulations. Title 40 arranges mainly environmental regulations that were promulgated by the US Environmental Protection Agency (EPA), based on the provisions of United States laws. Parts of the regulation may be updated annually on July 1.
The Terrafugia Transition is a light sport, roadable airplane under development by Terrafugia since 2006.
Federal Motor Vehicle Safety Standard 208 regulates automotive occupant crash protection in the United States. Like all other Federal Motor Vehicle Safety Standards, FMVSS 208 is administered by the United States Department of Transportation's National Highway Traffic Safety Administration.
Vehicle weight is a measurement of wheeled motor vehicles; either an actual measured weight of the vehicle under defined conditions or a gross weight rating for its weight carrying capacity.
Federal Motor Vehicle Safety Standard 116 regulates motor vehicle brake fluids in the United States. Like all other Federal Motor Vehicle Safety Standards, FMVSS 116 is administered by the United States Department of Transportation's National Highway Traffic Safety Administration.
Federal Motor Vehicle Safety Standard 401 establishes the requirement for providing a trunk release mechanism which allows a person trapped inside the trunk compartment to escape from the compartment in a passenger car in the United States. This standard does not apply to vehicles with a hinged back door found on hatchbacks and station wagons. Like all other Federal Motor Vehicle Safety Standards, FMVSS 401 is administered by the United States Department of Transportation's National Highway Traffic Safety Administration.
Federal Motor Vehicle Safety Standard 138 regulates motor vehicle tire-pressure monitoring system (TPMS) in the United States.
Federal Motor Vehicle Safety Standard 126 regulates motor vehicle electronic stability control (ESC) in the United States.
